The assessment and the farmers’ perceived ranking of feed resources and coping strategies with feed scarcity in smallholder dairy farming in selected district towns of Jimma Zone,Ethiopia

Inadequate quantity and quality of feed resources are major constraints limiting milk production and reproductive performance of dairy cattle in Ethiopia. The aim of this study was to assess dairy cattle feed resources, feeding practices, the farmers’ perceived ranking of feed resources, causes of feed shortage, and coping strategies to feed scarcity in smallholder dairy system in selected district towns of Jimma Zone, Ethiopia. Data were obtained by interviewing 52 randomly selected smallholder dairy farmers using structured questionnaires and through direct observations. Results showed that 20 main feed types used by dairy farmers were identified and categorized into natural pastures, crop residues, green feeds, hay, agro-industrial by-products, concentrate mix, and non-conventional feeds. Overall, natural pasture (mean rank = 0.453), non-conventional feeds (0.307), cut green feeds (0.086), conserved hay (0.076), crop residues (0.049), and concentrate feeds (0.029) were ranked as the main feed resources in decreasing order of importance. Natural pasture grazing (92.2% of the respondents), hay (35.6%), and green feeds (29.4%) were the most important conventional basal feeds used. Wheat bran (11.7% of the respondents) followed by commercial concentrate mix (9.4%), Noug seedcake (8.3%), grain (7.8%), and molasses (6.1%) were the concentrate supplements used. Overall, bulule-flour mill leftovers (67.2% of the farmers), bean and pea hulls (57.2%) and atella-local brew by-product (37.2%), enset (Ensete ventricosum, 34.4%), and sugarcane top (32.2%) were the non-conventional feeds available and used during feed scarcity. Barley and teff (Eragrostis teff) straws and maize and sorghum stovers were the main crop residues used in the dry seasons. Overall, 73.9, 12.2, 12.2, and 1.7% of the respondents practiced free grazing, zero grazing, semi-zero, and a combination of zero- and free-grazing systems, respectively. Over 84% of the respondents in the dry season and 50% in the wet season reported experiencing a shortage of feeds. Poor feed availability (73.9% of the respondents) was reported as the main causes of feed shortage followed by shortage of pastureland (7.8%). Increased use of bulule (55.6% of the respondents), crop residues (16.1%), non-conventional feed resources (14.4%), conserved hay (11.1%), purchased green feeds and concentrates (1.1%), and reducing herd size (1.1%) were the farmers’ adopted coping strategies to mitigate feed shortage. It is suggested that technical intervention to improve the quality and efficient utilization of the existing feed resources is crucial to enable sustainable feed supply and boost milk production. Technologies that are easy to adopt, feasible, and low cost are also needed to be developed in participatory manner.     

Smallholders’ perceptions of goat farming in southern Benin and opportunities for improvement

To be successful, initiatives to improve smallholder’s goat production should directly address the needs and objectives of the keepers while promoting rational use of local genetic resources. This paper identifies the objectives, constraints and needs of goat farmers in southern Benin and discusses their relevance to the development of improvement programmes. Between November and December 2005, structured questionnaires, focus group discussions and participant observation were used to collect information from 38 goat farmers in two selected locations. Goats were kept mainly for sale whenever cash was needed. Traits related to reproduction, to behaviour, to health and to meat production were considered equally important and were ranked very highly by goat keepers. Increased net income per flock through increased number of marketable animals is the derived breeding objective from the trait analysis. Disease outbreaks resulting in high mortality, poor housing, and feed shortages were, in descending order, the most important problems. It was concluded that the development of initiatives to improve management practices is an overriding priority. It will lead to increases in productivity in the short term and foster farmers’ participation in the development of long-term improvement strategies, which should include selection and controlled mating.     

Local breeds,livelihoods and livestock keepers’ rights in South Asia

In South Asia, and throughout the developing world, the predominant official approach to livestock development has been improvement of production by means of upgrading local breeds via cross-breeding with exotic animals. This strategy has led to the replacement and dilution of locally adapted breeds with non-native ones. This has resulted in an alarming loss that has been estimated by the Food and Agriculture Organization of the United Nations to amount to one breed every two weeks. Based on selected case studies this paper argues that development strategies using locally adapted breeds and species are much more likely to benefit livestock keepers whilst also maintaining domestic animal diversity and bearing a smaller ecological footprint. It also analyses the rationale for “Livestock Keepers’ Rights”, a principle that grew out of the struggle of traditional livestock keepers to retain control over their production resources, such as grazing areas and breeding stock, in the face of unfavourable policy environments.     

Calf morbidity and mortality in smallholder dairy farms in Ada’a Liben district of Oromia,Ethiopia

A longitudinal observational study on calf morbidity and mortality was conducted in smallholder dairy farms in Ada’a Liben district of Oromia, Ethiopia. A total of 185 calves from 112 market oriented smallholder dairy farms were selected randomly and regularly monitored for clinical health problems up to six months of age. Information on potential risk factors was collected by personal observation during the regular visit to farms and from questionnaire survey conducted during the study period. The overall incidences of crude morbidity and crude mortality were 62 % and 22%, respectively. The most frequent disease syndrome was calf diarrhea with the incidence of 39% followed by joint ill 6%. The other disease conditions/syndromes diagnosed include navel ill, pneumonia, septicemic conditions, congenital problems and miscellaneous cases. Age of the calves, age at first colostrum ingestion and cleanness of the calf barns significantly influenced morbidity. Older calves (greater than three months of age) were at lower risk of crude morbidity than younger calves (less than three months of age) (HR = 0.42, P = 0.001). Higher risk of crude morbidity was observed in calves that ingested their first colostrum meal later than 6 hours of age compared to those that ingested colostrum earlier (HR = 2.24, P = 0.001). Similarly, calves housed in unclean barns were at higher risk of morbidity than calves housed in clean barns (HR = 1.75, P = 0.024). Of the 20 potential risk factors investigated, age was the only factor that was found significantly associated with mortality (HR = 0.04, P = 0.001). Calves older than three months of age were at lower risk of mortality than younger calves.     

Ecology of Wahlberg’s velvet gecko,Homopholis wahlbergii,in southern Africa

We examined 170 museum specimens of the southern African gekkonid lizard Homopholis wahlbergii, to quantify sexual dimorphism, male and female reproductive cycles and diet. The largest male and female we recorded were 116 and 119 mm snout–vent length (SVL) respectively. We compared SVL, tail length, head length, head width and eye diameter and found no evidence of sexual dimorphism in any of these characters. The smallest female with thickened muscular oviducts and follicles, indicating sexual maturity, was 59 mm SVL, but the smallest female we found with fully developed eggs was 85mmSVL. Virtually all females larger than 59 mm appeared to be in some stage of reproduction, suggesting that females reproduce every year once they reach sexual maturity. Egg size ranged from 17–19mm long. Egg size was not correlated with maternal SVL. We found adult females with ready-to-lay eggs during the warmer months of the year, but not during winter and spring. The smallest sexually mature male was 72 mm SVL. Virtually all males larger than this size displayed at least semi-turgid testes and most adult male testes were at least semi-turgid for much of the year. The only significant decrease in testicular activity was in mid-winter (June–August), thus, spermatogenesis is closely tied to female follicular development and ovulation. Velvet geckos are largely insectivorous (92%) and feed on a broad spectrum of prey. Their diet was dominated both numerically (34%) and volumetrically (22%) by beetles. Lepidoptera were the next most important prey category, suggesting that they exploit both terrestrial and flying invertebrates. They are unusual among lizards because they feed on millipedes. Males and females had very similar diets which may be explained by their lack of sexual dimorphism, although females tended to eat a greater volume of prey. Interestingly, less than half (37%) of the lizards examined contained prey items, suggesting that most individuals were not in positive energy balance. We also found evidence of prey size selection as a function of gape size, such that larger geckos took advantage of larger prey items.     

Assessment of the nutritional status of indigenous scavenging chickens in Ada’a district,Ethiopia

The nutritive values of scavenging feed resource bases and effects of season and chickens age on the latter were studied in smallholder farms in Aad’a, Ethiopia. The study included 210 households and 208 chickens. The mean weight of crop contents in all age groups ranged from 26.2 to 28.2 g, while it was 29.8 g and 24.7 g in the harvesting and non-harvesting seasons, respectively. Grains represented 48–49% of the mean weight of crop contents in all age groups and it was significantly higher (P < 0.05) during the harvesting season than the non-harvesting period in both age groups. Kitchen wastes were next in abundance (26–29%) and were significantly more abundant in non-harvesting season in growers only and in hens than in growers (P < 0.001). The dry matter, crude protein, crude fiber, calcium, phosphorous and metabolizable energy levels of crop contents were 91.1–92.5%, 12.9–15.5%, 4.17–7.07%, 0.43–0.90%, 0.28–0.38% and 3404.3–3636.2 Kcal, respectively. Crude protein, calcium and phosphorus levels were below the requirements for egg production and growth. The scavenging feed resource base was critically deficient in these nutrients during the harvesting season. As these nutrients are vital for production, supplementary feeds rich in these nutrients would probably result in increased egg production and optimum growth.     

Pastoralists’ knowledge and practices towards clinical bovine dermatophilosis in cattle herds of North-Central Nigeria: the associated factors,burden and economic impact

Dermatophilosis is a contagious disease of high economic importance. The study assessed knowledge/awareness and clinical burden of and mitigation measures practised against clinical bovine dermatophilosis in pastoral herds of North-Central Nigeria and associated socio-cultural factors that predisposed to its occurrence in herds. A cross-sectional survey was conducted between October 2015 and September 2016. Questionnaires were administered on pastoralists and clinical assessment of cattle with gross pathological lesions indicative of dermatophilosis conducted. Associated economic impact was estimated. All 384 selected pastoralists participated in the survey. The majorities of nomadic (97.4%) and sedentary (68.2%) pastoralists significantly (p < 0.05) reported to have heard about dermatophilosis. Majorities of the sedentary (91.7%) and nomadic (97.4%) pastoralists mentioned the use antibiotics to manage the disease. Pastoralists in age group 70–79 years were more likely (OR 15.22; 95% CI 4.69, 49.34) to possess satisfactory knowledge about the disease. Culture of giving out cattle as gift or payment for dowry was more likely (OR 28.56; 95% CI 15.64, 52.12) to influence dermatophilosis occurrence in herds. Overall clinical dermatophilosis burden was 3.6% (95% CI 3.46, 3.80) and the annual economic impact was estimated at 908,463.9 USD. This study has given an idea to the status of pastoralists’ levels of awareness about dermatophilosis in Nigeria, which can be harnessed by policy makers to develop its mitigation measures. Significant influence of pastoralists’ socio-cultural activities on dermatophilosis occurrence in herds was identified. Surveillance and control programmes towards dermatophilosis that take these factors into consideration will be beneficial to the herders.     

Feed inventory and smallholder farmers’ perceived causes of feed shortage for dairy cattle in Gisagara District, Rwanda

A survey was conducted to indentify dairy cattle feed resources and smallholder farmers' perceived causes of feed shortage in the central and southern plateaus of Gisagara District, Rwanda. Data were obtained by interviewing 120 smallholder milk producers using structured questionnaires and through direct observations made during transect walks. In all the surveyed areas, rangelands (mean rank?=?1.12), crop residues (1.21), improved grasses (2.34), browse (3.23) and herbaceous (4.84) legumes were ranked as the main feed resources. Pennisetum purpureum (95% of the respondents), Leucaena diversifolia (60%) and Calliandra calothyrsus (40%) were the most cultivated fodders in all the plateaus. The dominant crop residue was Zea mays stover (65% of the farmers) in the surveyed areas. In both plateaus, land scarcity was ranked (mean rank?=?1.45) as the most important cause of feed shortage followed by inadequacy of forage planting material (2.72) and lack of knowledge on forage production and utilisation (3.02). To ensure sustainable viability of smallholder dairying in densely populated highlands, screening and evaluation of high-yielding and easily propagated pastures, incorporation of forages into cropping systems, value addition of low quality roughages and training farmers on forage production and utilisation should be prioritised.     

Clients’ perceptions of delivery of veterinary services in peri-urban Ghana

A study was designed aimed at comparing the assessment of performance of animal health care delivery systems in peri-urban Ghana by livestock and poultry keepers in 4 locations. 889 respondents were interviewed using a questionnaire. A higher proportion of respondents in Location 1 met their needs for animal health by themselves, while in Location 3 these needs were met mainly by veterinarians. The mean distances to veterinary clinics, veterinary technicians or to purchase medicine were significantly higher in Location 1. Higher proportions in 3 locations perceived effectiveness of service delivery to be good. However, equity was poor in all 4 locations. Higher proportions in Locations 2, 3 and 4 said services were unaffordable. Client needs were perceived to have been met by higher proportions in Locations 3 and 4 but not in Locations 1 and 2. Staff attitude and technical competence were good in all 4 locations. The study concluded that the differences reported in the quality of service indicators in the 4 locations were not critical enough to recommend location-specific delivery systems.     

Seroprevalence of infectious laryngotracheitis disease in backyard chickens in villages of Ada’a district,Oromia, Ethiopia: first report

Tropical Animal Health and Production - As per the report from the OIE in 2005, infectious laryngotracheitis (ILT) has not been yet reported in Ethiopia. Hence, considering the evident clinical...     

Investigation of Marek’s disease virus from chickens in central Ethiopia

Marek’s disease (MD) is a lymphoproliferative and neuropathic disease of domestic chickens and less commonly, turkeys and quails, caused by a highly contagious, cell-associated, oncogenic herpesvirus. In Ethiopia, MD is believed to be introduced with importation of exotic and crossbred to improve the poultry production and has been reported to be a potential threat to the poultry sector both in backyard and commercial farming systems. This study was aimed at isolation and molecular analysis of MD virus isolates circulating in chicken population in the central part of Ethiopia where commercial farms are populated. From September 2013 to January 2014, clinical and post-mortem examination were conducted on diseased chickens suspected of MD virus infection. Representative spleen and feather follicle samples were collected following sterile procedure, and infectious virus isolation was performed using primary chicken fibroblast cell culture. Cell culture inoculated with suspension of pathological samples developed characteristic MD virus cytopathic effect of rounding of the cells and small plaques. Further analysis of the virus was conducted by conventional PCR amplifying the ICP4 gene fragment from eleven tissue samples using MD virus specific primers. PCR products were further sequenced and analyzed. Nucleotide sequence similarity search of the local isolates resulted a high degree of sequence similarity with Gallid Herpes virus type 2 strain (Marek’s disease virus type 1, JN034558). To our knowledge, the present study is the first report conducted on virus isolation and molecular characterization of MD virus isolates circulated in Ethiopia. Eleven ICP4-like gene fragment (318 bp) sequences generated in the present study were uploaded in the public database (KU842366–76). Further research on virus isolation, genetic characterization, and infection dynamics is recommended targeting chickens of all age groups reared in different agro-ecological zones under different production system.

     

Are government veterinary paraprofessionals serving the poor? The perceptions of smallholder livestock farmers in Western Kenya

The liberalization of clinical veterinary services in Kenya introduced new service providers into the animal health service sector. This study examines the perceptions of livestock farmers regarding these service providers and analyses the factors that influence their choice of alternative service providers in Kakamega County. The empirical analysis shows that private animal health assistants were perceived to provide better services than alternative providers because they are more accessible and offer services on credit. Results from a multinomial logit model reveal that more educated, wealthier, and older farmers are more likely to use government services. The study concludes that it is imperative to better target the poor and to integrate private service providers into government animal health programs.

     

Status and prospects for livestock production in the Lao People’s Democratic Republic

Some 16 per cent of the Gross Domestic Product of the Lao PDR arises from the livestock sector. Almost all output - live animals and products - is from traditional small scale production and about 90 per cent of all households in the country keep one or more species of livestock. Industrial or large scale production is of very minor importance even for pigs and poultry. Considerable international assistance has been provided for livestock development, initially from the Socialist states that were of the same political persuasion as Lao PDR and more recently from multilateral and bilateral development assistance agencies. In general this assistance has not conferred lasting benefits on the sector in part due to the failure of the Lao Government to provide continuing support commensurate with the sector’s contribution to the national economy. Buffalo (1.1 million head in 2004) and cattle (1.3 million head) are the main ruminant species with goats and sheep (140 000 head) occupying a very minor position. Both pigs (1.7 million) and poultry (19.6 million) are major contributors to the household and national economies. Buffalo are now mainly meat producers, their former draught and transport roles having been taken over by mechanical equipment. Cattle, also once used for draught, are almost exclusively producers of beef. Pigs and poultry produce meat and poultry provide eggs. Lao indigenous livestock are mainly kept in low input systems, thus output is also low. Nothing is known of the genetic potential of the indigenous stock which are the victims of poor management, inadequate nutrition and minimal health care. There is strong and rising demand for products of animal origin within the country and in the greater Southeast Asia and East Asia regions. Given suitable and appropriate support the Lao livestock sector would be in a strong position to contribute to supplying this demand.     

Serological and parasitological survey of dourine in the Arsi–Bale highlands of Ethiopia

This study was conducted from August 2005 to January 2007 to determine prevalence and distribution of dourine in horses and to investigate the occurrence of clinical and carrier cases in donkeys and mules in the Arsi–Bale highlands. Study methodology was based on questionnaire, serological, clinical and parasitological survey. The questionnaire indicated that dourine is a major health problem of equines in the Arsi–Bale highlands. Though dourine is commonly observed throughout the year, it has a seasonal character and occurs mostly during the breeding season from June to late September. Serological screening of 646 horses showed a seroprevalence of 184 (28%), 161 (25%) and 125 (19%) for card agglutination test for trypanosomosis, LATEX and enzyme-linked immunosorbent assay, respectively. Risk factors were parity number, previous history of abortion and body condition score. No trypanosomes could be detected by Giemsa staining or by haematocrit centrifugation technique. Ten puppies inoculated with blood samples, genital washes and oedematous fluids remained parasitologically negative. Different characteristic signs of dourine were observed. During the genital stage, mares showed vaginal oedema, discharge and presence of depigmented scars over the external genitalia. In stallions, oedema of the scrotum and prepuce, prepucial and urethral discharge, and ulceration of the genital mucosae mainly of the penile were observed. In both sexes, lameness in one or both legs, partial dragging and stiffness of the hind legs and incoordination were the dominant signs observed as nervous form of the disease.     

Farmers’ perceptions of goat kid mortality under communal farming in Eastern Cape,South Africa

Rearing of goats under communal farming conditions is characterised by high kid mortality and low weaning percentages. A survey was conducted to determine farmers’ perceptions on the causes of kid mortality during summer under the communal farming system in Nkonkobe Local Municipality in the Eastern Cape, South Africa. This was done by administering questionnaires to a total of 162 respondents in 14 villages around Nkonkobe Local Municipality. The study showed that majority of farmers (75 %) keep flock sizes of less than 10 goats and kids, and this indicates that goat production in Nkonkobe Local Municipality is suppressed. According to the farmers, diseases (89 %), endo-parasites (72 %) and ecto-parasites (68 %) were perceived as the major causes of kid mortality. Other causes reported include starvation (15 %), extreme weather conditions (28 %), abortion (7 %), theft (35 %), diarrhoea (43 %), accidents (10 %) and wounds (9 %). The low number of goats could be attributed to high mortalities. It was also found that all causes reported by farmers played a role in high kid mortality in Nkonkobe Local Municipality. However, the causes which require more emphasis to formulate extension support were tick-borne diseases and parasites. This study provided baseline information on possible causes of kid mortalities in Nkonkobe Local Municipality. There is, however, a need to conduct further studies to determine actual causes of high kid mortalities so as to develop preventive strategies that would minimize kid mortality for good economic returns.     

Studies on the Respiratory Disease ‘Sonbobe’ in Camels in the Eastern Lowlands of Ethiopia

New epidemics of respiratory disease have caused 29.6 morbidity and 6.4% mortality in camels in the Somalia region of Ethiopia. The major clinical signs observed were fever of 40–41.5°C, depression, cough, loss of appetite and a watery nasal discharge that became mucopurulent at a later stage. Finally, the camel became recumbent and extended its neck straight along the ground. Some of the animals died within 8–9 days. The major post-mortem lesions were hydrothorax, adhesion of the lung to the thorax, red and grey hepatization, emphysema, hydropericardium and fibrinous pericarditis. A treatment trial indicated that oxytetracycline was more effective than a combination of penicillin and streptomycin, the results showing a significant difference (p>0.05) between the treated and control groups. The bacteria isolated from lung, thoracic fluid and whole blood were Pasteurella haemolytica. Further studies on the epidemiology of this disease, the identification of the serotypes involved, and the demonstration of any primary viral initiating agent are recommended to allow the development of preventive methods.     

The role of nuclear technologies in the diagnosis and control of livestock diseases—a review

Nuclear and nuclear-related technologies have played an important role in animal health, particularly in relation to disease diagnosis and characterization of pathogenic organisms. This review focuses primarily on how and where nuclear technologies, both non-isotopic and isotopic methods, have made their impact in the past and where it might be expected they could have an impact in the future. The review outlines the extensive use of radiation attenuation in attempts to create vaccines for a multiplicity of pathogenic organisms and how the technology is being re-examined in the light of recent advances in irradiation techniques and cryopreservation/lyophilization that might obviate some of the problems of maintenance of viable, attenuate vaccines and their transport and use in the field. This approach could be used for a number of parasitic diseases where vaccination has been problematic and where investigations into the development of molecular vaccines have still failed to deliver satisfactory candidates for generating protective immune responses. Irradiation of antigens or serum samples also has its uses in diagnosis, especially when the samples need to be transported across international boundaries, or when handling the pathogens in question when carrying out a test presents serious health hazards to laboratory personnel. The present-day extensive use of enzyme immunoassays and molecular methods (e.g., polymerase chain reaction) for diagnosis and characterization of animal pathogens has its origins in the use of isotope-labeled antigens and antibodies. These isotopic techniques that included the use of ⁷⁵Se, ³²P, ¹²⁵I, and ³⁵S isotopes enabled a level of sensitivity and specificity that was hitherto unrealized, and it is prescient to remind ourselves of just how successful these technologies were, in spite of their infrequent use nowadays. Finally, the review looks at the potential for stable isotope analysis for a variety of applications??in the tracking of animal migrations, where the migrant are potential carriers of transboundary animal diseases, and where it would be useful to determine the origins of the carrier, e.g., Highly Pathogenic Avian Influenza and its dissemination by wild water fowl. Other applications could be in monitoring sequestered microbial culture (e.g., rinderpest virus) where in the case of accidental or deliberate release of infective culture it would be possible to identify the laboratory from which the isolate originated.     

Farmers’ perceptions on trypanosomosis and trypanotolerance character of the taurine Sheko

In the humid and subhumid tropics, trypanosomosis is an economically important zoonotic protozoan disease of the commonly kept farm animal species and their wild relatives. For example, more than 20% of the humid western and southwestern Ethiopia, which is home to more than 14 million heads of cattle, is under varying levels of trypanosomosis risk. Our study was, therefore, initiated to document farmers’ perception on trypanosomosis and Sheko’s trypanotolerance character. Our findings showed that trypanosomosis was the most frequently reported cattle disease in the Bench Maji Zone. Accordingly, 76.7% of the farmers reported the epidemiological importance of trypanosomosis, and they also noted that trypanosomosis on average accounted for 63.0% of annualized cattle death. The reported signs of trypanosomosis and trypanotolerance indicators were consistent with literature reports. Moreover, 66.7% of the farmers reported Sheko’s trypanotolerance character. In the course of time, smallholder farmers have developed ethnoveterinary practices that are mainly used to prevent the landing of vector flies on the animal. Wet and warm seasons of the year, i.e., spring and, to some extent, the beginning of summer and autumn, were reported as peak periods of trypanosomosis risk. Therefore, this showed the need for incorporating farmers’ knowledge in trypanosomosis control programs.     

Calf survival and reproductive performance of Holstein–Friesian cows in central Ethiopia

This study was carried out to evaluate the reproductive performance and calves survival rate of Holstein–Friesian (HF) herd in Holeta, central highland of Ethiopia. A retrospective analysis of 26 years data was carried out, from which records of 724 age at first calving (AFC), 2,022 calving intervals (CI), 2,971 breeding efficiencies (BE), 260 abortions, 111 stillbirths were derived from 795 cows. Moreover, 738 female calves’ records were also included for survival rate study. The overall least squares means of AFC, CI, and BE were 40.9 ± 0.33 months, 475 ± 2.84 days, 81.9 ± 0.26%, respectively, while the incidence rates of abortion, stillbirth, and female calves survival rate for this herd were 8.0%, 3.4%, and 77.5%, respectively. The effects of parity number and year of birth/calving on CI and BE were significant (P < 0.001). Moreover, birth year had significant (P < 0.001) effect on AFC and calves survival rate, while calving season had significant effect on BE. The reproductive performance found in this study was lower than the performance reported in many tropical regions and the genetic potential of HF breed in their origins. Moreover, higher loss due to calf mortality was observed. Thus, the centre should consider appropriate measures to improve its herd reproductive performance and calves survival rate for attaining its aspired objectives.
