Retrospective Review of Carriage Horse and Mule Welfare in Charleston,South Carolina (2009–2012)

Equine Welfare and Carriage Horse Companies have been recently highlighted as matters of public concern, although little data exists to describe working conditions, municipal regulations, and veterinary attention. In light of the current pandemic of unwanted horses in this country, it is prudent for the veterinary community to identify objective measurements of satisfactory equine welfare in the carriage horse industry to regulate and maintain working horses in sound conditions. Retrospective data from a carriage company in South Carolina was collected from 2009 to 2012. Variables included days in work, hours and/or tours worked, veterinary charges, management practices, and environmental conditions. City veterinary reports were also reviewed for all five local carriage companies. The average number of days in work per animal ranged from 163 to 188 per year. On average, each animal performed 4.6 hour long tours per working day, resulting in an average 865 tours per year. Each animal cost on average $2.00 per day in veterinary costs, and $0.84 of each animal's tour went toward veterinary bills. Welfare among carriage horses is a subject on which equine veterinarians should be well versed; not only to answer questions from clientele but also to promote good working and living conditions for these animals in an effort to stem the number of unwanted horses in America. The carriage company reported in detail here provides acceptable welfare for their animals. Prospective studies are needed to collect objective, evidence-based data regarding stress levels in the animals.     

The 2011 South Dakota Equitarian Survey and Comparative Analysis of Equine Welfare on a South Dakota Native American Reservation

Economic stress and geographic isolation are barriers to proper veterinary care for horses on Native American reservations. The 2011 South Dakota (SD) Equitarian Survey was distributed to 135 equine veterinarians in SD to detect perceptions of effectiveness and best methodologies for improving reservation equine welfare. There was a positive correlation (P < .005) between the perceived importance and effectiveness of increased veterinary access and the importance of free care and owner knowledge in changing the health and welfare of SD’s reservation equine population. Thirty-nine percent of respondents claimed to have an interest in providing help for reservation equines; those with no veterinary experience on reservations tended not to have interest (P = .05). Previous experience practicing on a reservation impacted how crucial they believed horse owner knowledge or awareness was in changing the health and welfare of reservation equines (P < .04). The most commonly noted health threat and strength were poor nutrition and the absence of internal disease, respectively. In a subsequent analysis, 299 horses on the Cheyenne River Sioux Reservation were observed for welfare indicators and divided into groups by use: saddle, production, bucking stock, and performance. Average body condition score was 5 of 9 and did not differ between the four groups. Coat (P < .001) and hoof (P < .007) conditions varied between groups, with optimal conditions in the performance and saddle horse groups, respectively. Variable hoof, coat, and vaccination practices among the groups of reservation equines present an opportunity for health care education and welfare improvement.

Interface of epidemiology, pet population issues and policy

Progress has been made towards eliminating Rowan's "statistical black hole" regarding pet populations and their dynamics, although deficiencies remain. The challenge in the coming decade will be to continue the progress, and generate meaningful epidemiologic data. Veterinary epidemiologists will continue to play an important role in the generation, dissemination and translation of results from their studies into coherent, effective companion animal welfare policy.     

The change of nursing for oestrus induction (biostimulation): Effect of contact between rabbit doe and its young

This study focused on the effects on subsequent reproductive traits of females and development of the current litter as a result of different contact between the rabbit doe and its progeny when a temporary doe–litter separation was used for biostimulation. Immediately after parturition and adjusting to eight young per litter, multiparous Pannon White rabbit does (n = 400) were divided into five groups based on parity, doe condition, and weight of litter and the kits. Rabbits in the control group (C) nursed freely up to weaning at 35 days of age. In the group following local farm practice (F) using a metal-plate for separation, females nursed once a day (8 am to 9 am) for the first 14 days of lactation and freely afterwards. In three biostimulation groups, there was a change from free to once a day nursing before insemination (i.e. controlled nursing at 8, 9 and 10 days) provided with a wire-mesh separation (BW: permits visual, olfactory, and acoustic contact); using a metal-plate for separation (BM: no visual but possible olfactory, acoustic and vibration contact); or with taking the litter with the nest-tray 5 m away from the doe's cage (BN: there is no contact at all) and returning to free nursing just after AI (at 11 days in the morning) up to weaning. The type of separation exerted a significant influence on oestrus and subsequent kindling of does. Comparing C, F, BW, BM and BN groups, sexual receptivity (30.4, 45.4, 24.0, 25.6, 43.0%, respectively; P < 0.05), fertility (74.4, 84.2, 80.8, 80.3, 89.5%; P < 0.05) and kindling rates (71.1, 85.5, 76.9, 77.3, 88.2%, respectively; P < 0.05) improved in F and BN groups. The total number of kits born (10.0, 10.3, 10.5, 10.4, 9.55, respectively; P = 0.392) and kits born alive per litter (9.25, 9.65, 9.59, 9.83, 9.03, respectively; P = 0.607) were not affected, but newborn kit weight was numerically less in the BW group (69.7, 67.5, 65.5, 67.6, 67.3 g, respectively; P = 0.166). Growth rates of current progeny up to weaning were higher and identical in C and BM but less in F and BN groups (27.5, 25.6, 27.1, 27.3, 26.7 g/day, respectively; P = 0.001). However, the total weight of 70-day-old rabbits per doe did not differ significantly (17.51, 17.53, 17.54, 16.81, 15.81 kg, respectively; P = 0.271). On the whole, the production of the F, BM and BN groups was superior to that of the control and BW groups since subsequent kindling results improved without a significant reduction in slaughter rabbits per doe from current litters.     

Does milk yield reflect the level of welfare in dairy herds?

Under the assumption that milk yield may be reduced in herds with impaired welfare, the present study aimed at investigating whether milk yield could be used as a reliable indicator of welfare. In 125 commercial French dairy herds, the association between the welfare of the herd (evaluated using the Welfare Quality assessment protocol) and cow milk yield was investigated using linear mixed models. Positive associations were identified between milk yield and low aggressions between cows and good emotional state of the herd but there was a negative association with good health assessed through the occurrence of diseases and injuries. These opposite associations resulted in no association with the overall welfare of the herd. Milk yield should not therefore be used as an indicator of overall welfare.     

Casein hydrolyzate intramammary treatment improves the comfort behavior of cows induced into dry-off

The effectiveness of casein hydrolyzate as mean to improve the welfare of cows induced into involution was tested in high yielding cows induced into dry-off by abrupt cessation of milking. Treatment with casein hydrolysate prevented build up of udder pressure in cows induced into dry off and was clearly associated with signs (lying behavior and step numbers) that they were calmer and more comfortable than cows induced into dry off by the conventional means. We conclude that treatment with casein hydrolyzate is a viable treatment tool that can prevent the suffering associated with drying-off of high-yielding modern dairy cows.     

A Descriptive Study of Training Methods for Fédération Equestre Internationale Endurance Horses in New Zealand

Training measures, particularly those that examine the interactions between training volume, speed, and recovery, can improve understanding of training practices that contribute to success and avoid adverse horse welfare outcomes in endurance competitions. This study describes the training of Fédération Equestre Internationale (FEI) 100–160 km level horses in New Zealand. A convenience sample of 16 participants and 25 horses were surveyed before commencement of training. Participants then reported daily data for an entire nine-month season of training and competition. Participants began their season with predetermined goals and individual training plans for each horse. They intended to use competitions for training. Competitions contributed a median of 44% [IQR, 36%–49%] of total accumulated distance (in training and competition) for each horse for the season, despite being only 11% (207/1,933) of all days worked. Most starts (80%) were in domestic-level (CEN) competition ≤80 km. Speed ranged from 2–18 km/hour on home training days to 6–18.5 km/hour in CEN competitions and 10.9–16.9 km/hour in FEI competitions. Horses were worked 34% [IQR, 21–38] of days in training, ranging from 12% to 55% for individual horses. The most common horse health problem was lameness, affecting 12/25 horses, for a median of 9 (range, 1–78) days. This study highlights the potential for CEN data as a resource to improve understanding of training and competition load, speed, and recovery and therefore reduce adverse horse welfare outcomes in FEI competitions.     

Effect of age and sex in determining cognitive ability in Vanaraja chickens

(1) To evaluate the cognitive ability of male and female Vanaraja birds, three hundred and sixty 1-d-old sexed chickens were reared under similar conditions in three treatment groups with 4 replicates in each group: 120 females in Treatment 1, 120 males in Treatment 2 and both males and females (60 + 60) as a mixed group in Treatment 3.

(2) To assess learning ability, the birds were trained in T- and Y-mazes and tested at 3-week intervals in 4 test schedules (21, 42, 63 and 84 d). The birds were put into tonic immobility (TI) in each test schedule.

(3) In each maze test, the latency to find the feed was regarded as a successful completion of the task. In the TI-test, the time taken to stabilise on a plane surface after swinging in the hanging cradle for 20–25 s was recorded.

(4) The results indicated that male birds appeared to be cognitively superior to females in terms of learning and cognitive evolution in all the mazes, but by d 84, the females performed as well as the males. With increasing age, spatial memory gathering and processing improved. In the TI-test, the effect of sex or grouping system had no significant effect on the performance of birds at the various ages.     

Aspects of the owning/keeping and disposal of horses, and how these relate to equine health/welfare in Ireland

Background

Ireland has long been renowned as a major centre for the breeding, rearing and keeping of horses. Since 2007, however, there has been increasing concern for horse health and welfare standards, and links between these concerns and the structures, governance and funding of the Irish equine industries have been reported. This paper addresses two central issues: firstly the local governance of, trade in and disposal of unwanted horses; and secondly mechanisms employed to improve standards of care given to horses owned by certain communities.

Method

Primary information was gathered through visits to horse pounds run by and on behalf of Local Authorities, to social horse projects, to horse dealer yards, ferry ports, horse slaughter plants and knackeries.

Results

The approach adopted by members of a given group, e.g. ferry ports, is described and differences are highlighted, for example in how different Local Authorities implement the Control of Horses Act of 1986, and how the choice, for example, of disposal route affects the standard of animal welfare.

Conclusions

There is a pressing need for a more centrally mandated and uniformly applied system of governance to safeguard the health and promote the keeping of horses to a higher welfare standard in Ireland. Fundamental to an understanding of why there is insufficient oversight of the keeping and proper disposal of horses is the lack of a comprehensive, integrated system for the registration, identification and tracing of equidae in Ireland.     

Aggressive behaviour of sows at mixing and maternal behaviour are heritable and genetically correlated traits

This study was designed to estimate genetic variation in aggressive behaviour of sows at mixing, and in maternal ability for the same sows. The study included 835 sows observed for number of mild or severe aggressions performed (F_A1, F_A2), or received (F_R1, F_R2) during 30 min after grouping. Maternal ability was recorded as sows' response to vocalisation from their piglets when these were handled. Maternal behaviour was studied in 1076 sows as a body reaction (MBR) to their piglets being handled after farrowing. Genetic covariances were estimated using a multi-trait animal model, assuming traits to be normally distributed. The heritabilities of performed aggression traits were intermediate (h² F_A1=0.17, h² F_A2=0.24), but lower for received aggression (h² F_R1=0.06, h² F_R2=0.04), and heritability of maternal behaviour was also low (h²=0.08). Although estimates of genetic correlations had large standard errors, they indicate that less aggressive sows were stronger responding mothers (r_g=−0.3). We conclude that performed aggression in sows is a heritable trait, and selection against aggression is possible without offsetting maternal behaviour.     

Welfare-positive management and nutrition for the dairy herd: A European perspective

As European dairy farms become larger and diverge between grass-based and fully housed systems, interest in the welfare of the dairy cow and related environmental issues by consumers and legislators is increasing. These pressures mean that good nutrition and management, which underpin much dairy cow welfare, is critical. Despite considerable research into the management and nutrition of the dairy cow from calf to adulthood there is much on-farm variability in its application. While the incidences of many endemic diseases are reduced most are still significant, for example lameness. In addition, trade and climate change are bringing a more diverse range of pathogens, parasites and pests into Northern Europe. Housing aspects are limited in application by economics and in most cases still do not match grazing for welfare in temperate climates. Genomic technologies offer increased opportunities to breed for ‘robustness’ but like ‘precision animal management systems’ have still to be fully exploited.     

Description of the Responses of Some Blood Constituents to Rodeo Exercise in Chilean Creole Horses

The aim of this study was to assess the effect of the Chilean rodeo exercise on some blood constituents, classically used to assess welfare, during rest; training with and without steer; and before and after official competitions. During the training season, 13 horses were assessed at their farms of origins, and samples were taken at rest and after training with and without a steer; then during the competition season, 16 horses were assessed at four different times, one before and three after the competition. The blood constituents assessed were packed cell volume (PCV), total proteins, fibrinogen, cortisol, neutrophil:lymphocyte ratio, creatine phosphokinase, aspartate transaminase, glutathione peroxidase, and serum amyloid A. Analysis of variance for repeated measures was applied using the Statistix 8.0 software, and a significance level of P < .05 was applied. For horses assessed during exercise with and without a steer, significant differences were observed for PCV, which were significantly lower at rest than after both exercises, and total proteins, which showed a significant increase only after exercise with steer. In the case of official competitions, PCV was significantly higher immediately after rodeo, and the lowest value for cortisol was observed the evening after competition (P < .05); among the enzymes assessed, creatine phosphokinase plasma concentrations immediately after rodeo and the evening after competition were significantly higher than concentrations the next morning. The use of physiological indicators did not seem to be sufficient to assess the overall effect of rodeo on the welfare of these horses, and other types of indicators should be considered in future studies.     

Factors affecting the success of rehoming dogs in the UK during 2005

In the UK, welfare organisations care for several thousand dogs each year. The successful rehoming of these dogs is a difficult process resulting in some of them being returned to rehoming centres. There have been very few studies examining the underlying mechanisms in the UK. Therefore, this study was conducted to determine those factors which affect the success of rehoming dogs.A prospective cohort study was conducted using a sample of 5750 dogs rehomed by Dogs Trust, a UK based dog welfare charity, during 2005. Dogs were followed up for a period of 6 months after adoption to determine if these dogs were still in their placement home. There was a 78% response rate to the follow-up postal questionnaires sent to the new owners, giving information on 4500 owners. Fourteen percent of adoptions failed. The results showed that behavioural problems are an important factor in the success of adoption such that if dogs had shown aggression towards people and the owners had not sought advice, they had 11.1 times the odds (95% CI: 6.6, 18.8) of being returned compared to those dogs without behavioural problems. Attending training classes significantly decreased the chance that the adoption would be unsuccessful (OR 0.3, 95% CI: 0.2, 0.4). It was shown that those owners who found that the effort and work involved in looking after their dog to be more than they had expected, had 9.9 (95% CI: 4.1, 24.6) times the odds of returning their dog than those who found the effort required to be less than they had expected.The results of this study show that there are many factors involved in a successful adoption and it is important that the new owners are informed of what to expect are encouraged to attend training classes and are prepared to work at any behavioural problems that their dog may have.     

Analysis of Noxious Gas Pollution in Horse Stable Air

The aim of this study was to determine quantitative and qualitative occurrence of noxious gas compounds in the stable, depending on the time of the day (4:00 AM, 12:00, 8:00 PM), the height (20 cm, 150 cm), and the place (boxes, aisle) from which the samples were collected. Seven compounds were analyzed (NH₃, SO₂, COS, HCN, CH₄, NO₂, and CO). For analyzing stable air, a mobile gas analyzer was used. The time of day was a significant differential factor (P < .01) for concentrations of NH₃, COS, and CH₄. The highest concentrations of CH₄, COS, NO₂, NH_3, and CO appeared at 4:00. For the rest of the studied compounds (SO₂, HCN, CO) differences were not statistically significant, but there was a tendency for the highest concentrations at 12:00. The concentrations of gas compounds depending on height did not differ significantly from each other, but there was a tendency for higher concentrations of NH₃, SO₂, CH₄, and CO at 150 cm and for HCN at 20 cm. COS and NO₂ remained constant at both heights in boxes. The places where the samples were collected was a significant differential factor (P < .01) for NH₃ and SO₂. For the rest of the studied compounds the differences were not statistically significant. It can be concluded that many noxious compounds may appear without being noticed, and that is why it is necessary to provide stables with efficient air exchange throughout the day.

Mortality and Operational Attributes Relative to Feral Horse and Burro Capture Techniques Based on Publicly Available Data From 2010-2019

Management of excessive feral horse (Equus ferus caballus) and burro (Equus asinus) populations in the United States and globally has been a controversial subject for decades. I reviewed all available US federal feral horse and burro daily gather reports from 2010 to 2019 to extract equine species, technique (bait trapping or helicopter gathering), reason (emergency or other), number gathered, number of mortalities, and mortality attributes (acute or chronic/pre-existing condition, specific cause). I found 70 reports (bait trapping burros n = 10, bait trapping horses n = 24, helicopter gathering horses n = 21) from 9 states (AZ, CA, CO, ID, MT, NV, OR, UT, WY) representing 28,821 horses and 2,005 burros. For bait trapping, 100 animals died (4 burros, 96 horses) with 16 acute causes (1 burro, 15 horses) and 84 chronic/pre-existing causes (3 burros, 81 horses). For helicopter gathering, 268 horses died with 62 acute causes and 206 chronic/pre-existing causes. Mortality ratios did not differ by capture technique (P > .05) for broken necks, emaciation, acute causes, or chronic/pre-existing causes. The most common mortality-causing problems were structural deformations, club foot, blindness, and emaciation. The more horses gathered per day resulted in a greater proportion of chronic/pre-existing mortalities for both trapping techniques, but only an increase of acute mortalities for helicopter gathering. The slope suggests 1 acute mortality for every 300 horses gathered. The capture mortality rate across all gathers [1.1% (368 mortalities out of 30,826 horses and burros captured)] is below a general threshold of 2% suggested for wildlife studies.
