In order to evaluate the influence of different N rates on percent N derived from fertilizer (%Ndff) at different growth stages, on yields and the percent N use efficiency (%NUE) values of two winter wheat varieties (durum and bread), field experiments on fallow were carried out at four different locations in Central Anatolia, in the 1991–1992 and 1992–1993 growing seasons. At each site the rates of N (0, 40, 80 and 120?kg N/ha) were applied as ammonium sulphate [(NH4)2SO4] using a Latin Square experimental design with four replicates. The total amounts of N fertilizer were applied once after seedling emergence at all experimental sites. Labelled (15NH4)2SO4 fertilizer was applied to sub-plots from which %Ndff values were determined at tillering, booting, grain filling, and harvest stages. Yield sub-plots received unlabelled (NH4)2SO4 from which total dry matter (seed and straw) and N yields were determined. Also the %NUE values were calculated by the 15N and "difference" methods at the harvest stage. Stored soil moisture at 0–90?cm depth, evapotranspiration and water use efficiency values were calculated as well. The results obtained showed that (1) Gerek-79 variety used both the applied N fertilizer and the available soil moisture more efficiently, (2) the percent NUE values obtained overall were generally less than 20 for both varieties and (3) with the 15N method, less variable %NUE values were obtained in comparison to the difference method. 相似文献

The aim of this study was to determine the effects of early feed restriction on performance, carcass characteristics, meat
and liver composition, some blood parameters, H-L ratio, antibody titers against SRBC and tonic immobility duration in broilers.
One hundred ninety male chicks (Ross 308) were randomly allocated into two treatment groups each of 95 chicks. Broilers in
one treatment fed ad libitum until 42 day of age, however in other treatment, broilers were deprived of feed for 4 h per day
from 7 to 21 day. Body weight, feed consumption, feed to gain ratio, carcass characteristics and the percentage of examined
organs except heart were not statistically significant in groups. Percentage of heart was higher (p < 0.05) in broilers fed
ad libitum. At 41 d of age, H-L ratio (p < 0.05) and TI duration (p = 0.001) were higher, serum glucose (p < 0.05) and triglyceride
(p < 0.001) levels were lower in broilers fed ad libitum. Chemical composition of breast and thigh and also fat and ash of
liver were not affected by early feed restriction. Moisture of liver (p = 0.001) was lower and protein of liver (p < 0.01)
was higher in broilers fed ad libitum 相似文献

Randomly Amplified Polymorphic DNA markers were used to determine the genetic relationships among Turkish lentil cultivars
and breeding lines. Fourteen cultivars and thirteen breeding lines were evaluated to determine genetic variability using nine
random 10-mer primers (among 45 primers). Forty-one reproducible bands were obtained, 54% of which were polymorphic. Genetic
distances among cultivars and breeding lines were obtained from the simple matching coefficients (SM). The lowest genetic
distance was observed between the cultivars of Ali Dayi and Kafkas with 5.0%, while ‘Seyran-96’ and ‘Ozbek’ had the highest
genetic distance with 58.3%. An unweighted pair-group method with arithmetic averages (UPGMA) cluster analysis was performed
on the distance matrix using Phylip software. The dendrogram clearly showed two distinct groups. The first group is composed
of Akm 565 and Akm 563. The second group contains all the cultivars and remaining eleven breeding lines. 相似文献

The analgesic effect of wound
infiltration with bupivacaine was evaluated in cats undergoing bilateral mastectomy.
Twenty-one female cats with mammary gland tumors were anesthetized with propofol and
oxygen-isoflurane anesthesia following premedication with atropine. In the trial group
(Group I; n=11), 30 ml of saline containing 2 mg/kg of bupivacaine was
infiltrated topically into the surgical wound right after removal of the mammary glands,
whereas only saline solution was infiltrated in the control group (Group II; n=10). At the
same time, carprofen (4 mg/kg) was also administered subcutaneously in both groups.
Behavioral signs of pain were monitored during the recovery period after general
anesthesia. In order to examine the behavioral changes associated with acute pain, a
questionnaire was prepared and given to the owners to be completed 4 hr and then 10 hr
after the operation. According to the owners’ anwers to the questionnaire, a pain score
was specified using a “numerical rating scale” for each cat. Although some cats showed
mild to moderate pain, the pain score recorded at 4 hr after the operation was
significantly lower in Group I (P<0.001). No significant difference
was found at 10 hr after the operation between the groups. The incidence of vocalization,
aggression and convulsion within 2 hr after the operation was also lower in Group I. In
conclusion, wound infiltration with bupivacaine before incisional closure provided
reliable analgesia at least 4 hr after bilateral radical mastectomy in cats. 相似文献

Equine adenovirus type 1 (EAdV-1) is a cause of repiratory tract infection in equids. In present study for the first time in Turkey, the prevalence of EAdV-1 in nasal swab samples obtained from horses showing respiratory symptoms was investigated by polymerase chain reaction (PCR), and molecular characterization of the hexon gene detected in the Turkish (TR) strain was performed. Overall, the prevalence of EAdV-1 was found low (1.4%) as indicated by a positive PCR reaction from the nasal swab extracts tested. Phylogenetic analysis based on the partial sequences of the hexon gene of a TR-EAdV-1 strain with those of previously isolated AdVs from different mammals and an EAdV-1 M1 strain showed that the EAdV-1 strains were placed into a unique cluster. Although the TR-EAdV-1 strain was closely related to CAV-1, CAV-2 and bat adenovirus reference strains, larger-scale studies are necessary to better understand the molecular epidemiology and population structure of EAdV-1 in Turkey. 相似文献

High concentrations of boron (B) in the soil, reduces plant growth, crops’ yield and quality. Regarding such problem, synergistic and antagonistic relations between the nutrients can be used to ameliorate the B toxicity. Therefore, a greenhouse experiment was conducted to evaluate effects of soil-applied zinc (Zn), nitrogen (N), calcium (Ca), lime (CaCO3), potassium (K), humic acid (HA), and humus on the dry weight and B uptake of maize shoots (Zea mays L.) under high-B containing soil conditions. Increasing doses of B (0, 2.5, 5, and 10 mg kg?1 B) were applied to soil as borax (Na2B4O710H2O), and boric acid (H3BO3). Positive correlations were found between B doses and the uptake amounts (r = 0.934**; – 0.964**). However, the correlations between the dry weight and B doses (r = ?0.314**; – r = ?0.495**) and between the dry weight and the uptake amounts (r = ?0.294*; – r = ?0.497**) were negative. Among the materials, Zn and humus exhibited positive correlations with dry weight values (r = 0.249*; r = 0.525**), and an effective increase (p < 0.01) in the dry weight amounts of maize shoots was observed under toxic B conditions. 相似文献

Effects of kefir on coccidial oocysts excretion and performance of dairy goat kids following weaning
Daş G Ataşoğlu C Akbağ HI Tölü C Yurtman IY Savaş T 《Tropical animal health and production》2012,44(5):1049-1055
The aim of this study was to investigate effects of kefir, a traditional source of probiotic, on coccidial oocysts excretion
and on the performance of dairy goat kids following weaning. Twin kids were randomly allocated to one of two groups at weaning.
Kids of the first group received 20 ml of kefir daily for 6 weeks (KEF), while kids in the control group were given a placebo
(CON). Individual faecal samples were regularly (n = 18 per kid) taken to quantify the number of coccidial oocysts per gram of faeces (OpG). There were no differences between
the groups in terms of body weight development (P > 0.05) and feed consumption. Kids of both groups were not able to consume enough feed to meet their nutrient requirements
during the first 3 weeks following weaning. KEF had a lower frequency of OpG positive samples than CON (P = 0.043). Kefir did not affect the maximum oocyst excretion and age of the kids at the highest oocyst excretion (P > 0.05). KEF shed numerically 35% lower coccidial oocysts than the controls, which corresponded to a statistical tendency
(P = 0.074) in lowering Log-OpG in comparison to CON. While KEF had a lower frequency of OpG positive samples and tended to
shed lower OPG by around one-third, the frequency of diarrhea, level of highest oocyst excretion, and performance of the kids
remained unaffected. Therefore, it is concluded that overall effects of kefir do not have a significant impact on sub-clinical
infection and performance in weaned kids under relatively high-hygienic farming conditions. 相似文献

Amoxicillin is used in the treatment and prevention of a wide range of diseases in poultry breeding. However, its short half‐life and low bioavailability restrict its clinical application in these species. Entrapment of drugs into polymeric nanoparticles (nps) presents a means to improve gastrointestinal absorption and oral bioavailability of drugs. This study was aimed to overcome limitation of amoxicillin use in poultry breeding. Amoxicillin was loaded into sodium alginate‐polyvinyl alcohol (NaAlg‐PVA ) blend nps, and characterization of the prepared nps was performed. For pharmacokinetic study, commercial male broilers were used and comparative pharmacokinetics of free and nanoparticle form of amoxicillin were investigated. Twenty‐one broilers were divided into three groups. All groups received 10 mg/kg drug. Blood samples were collected, and drug plasma concentrations were determined by HPLC . The results demonstrated that the particle size, zeta potential, encapsulation efficiency, and loading capacity of the nps were 513.96 ± 19.46 nm, ?45.36 ± 1.35 mV , 43.66 ± 3.30, and 12.06 ± 0.83%, respectively. In vitro drug release exhibited a biphasic pattern with an initial burst release of 18% within 2 hr followed by a sustained release over 22 hr. The pharmacokinetic results showed that amoxicillin nps have higher bioavailability and longer plasma half‐life (p < .01) than free amoxicillin. These results indicate that amoxicillin nano formulation is suitable for oral administration in broilers. 相似文献

Investigation of tetracycline and degradation products in Euphrates river receiving outflows of trout farms 下载免费PDF全文
In this study, tetracycline (TC), epitetracycline (ETC), 4‐epianhydrotetracycline (EATC) and anhydrotetracycline (ATC) concentrations were determined in the surface waters carrying outflows of trout farms. The samples were taken from downstream of Keban Dam and upstream of Karakaya Dam Lake, which are located in the Euphrates and Tigris River Basin. The occurrence of TC and degradation products (DPs) was proved in the sampling points which take the outflows of the trout farms. Tetracycline and DPs were under the detection limits in sampling points where the trout farms do not exist. The highest TC concentration was detected as 50.0 ± 2.5 μg L?1 (1st week), whereas the lowest TC concentration was 8.2 ± 0.41 μg L?1 (7th week). The highest ETC concentration was 88.1 ± 4.4 μg L?1 (3rd week)and the lowest ETC concentration was 9.4 ± 0.4 μg L?1 (3rd week). The highest and lowest EATC concentrations were detected as 35.8 ± 1.8 μg L?1 (2nd week) and 8.2 ± 0.4 μg L?1 (2nd week) respectively. The highest ATC concentration was 28.3 ± 1.4 μg L?1 (3rd week), whereas the lowest was 6.54 ± 0.34 μg L?1 (7th week). Tetracycline and DP concentrations detected in surface waters followed the following order: ETC>TC>EATC>ATC. 相似文献
