Department of Animal Science: Faculty Publications
Records of 9,055 lambs from a composite population originating from crossing Columbia rams to Hampshire ´ Suffolk ewes at the U.S. Meat Animal Research Center were used to estimate genetic parameters among growth traits. Traits analyzed were weights at birth (BWT), weaning (7 wk, WWT), 19 mo (W19), and 31 mo (W31) and postweaning ADG from 9 to 18 or 19 wk of age. The ADG was also divided into daily gain of males (DGM) and daily gain of females (DGF). These two traits were analyzed with W19 and with W31 in three-trait analyses. (Co)variance components were estimated with REML …

The aim of this study was to estimate genetic and phenotypic (coroariances between objective measures and carcass visual scores, as a test of the potential value afvisual scores in selection programmes to improve carcass composition in crossbred lambs. In each of 1986, 1987 and 1988, 22 Suffolk rams were chosen with either high or low scores on an index designed to increase lean growth rate. These rams were joined with 18 to20 crossbred ewes each and theirlambs were grov.J11 on grass to one of three target live weights (35·5, 41·5 and 47·0 kg) for slaughter. The carcasses of 1881 lambs …

This study was carried out with the aim to investigate of histological structure of duodenum and histochemical character of duodenal mucous on Akkaraman sheep foetus by during intrauterin development. In the study, the number 40 duodenum belonging to the Akkaraman sheep foetus was used as a material. More concentrate neutral mucosubstans and glycogen containing of Lamina epithelialis was determined that it is multilayer structure showing on early development stages not to be found of villi. The later development stages, neutral and asidic mucosubstans containing of goblet cells on Lamina epithelialis was detected that it is convertible to monolayer prizmatic form. …

In this trial based on the reduction of the egg output and on the evaluation of results from larval/egg differentiation, moxidectin (Cydectin, 1% injectable moxidectin) administrated subcutaneously at a dose of 0.2 mg kgbw -1 was found effective on the gastrointestinal nematodes in naturally infected lambs (8 female and 7 male treatment; 8 female and 7 male control) harbored Haemonchus spp, Ostertagia spp, Trichostrongylus spp and Nematodirus spp and in naturally infected female calves (20 treatment and 10 control) harbored Haemonchus spp, Ostertagia spp, Trichostrongylus spp, Bunostomum sppand Cooperia spp.The efficacy was 100% on day +7, 99.9% on day +14 …
Finding Western Australia's Most Profitable Merino Flocks, David Windsor
Finding Western Australia's Most Profitable Merino Flocks, David Windsor
Journal of the Department of Agriculture, Western Australia, Series 4
Wether trials across Western Australia are showing significant differences in Merino flock productivity, which have important implications for whole-farm profitability. David Windsor reports on how wool growers in the 21 st century can maximise productivity by combining superior management skills with the best available genetic material.

Turkish Journal of Veterinary & Animal Sciences
This study was carried out to determine the prevalence of liver fluke infections in cattle and sheep in Trakya (The European Part of Turkey). For this purpose the slaughterhouses of different localities (Tekirdağ, Hadimköy, Lüleburgaz, Çorlu, Kırklareli and Keşan) were visited between 03.03.1997 and 22.10.1997, and a total of 476 sheep and 415 cattle livers were examined. The prevalence rates of fasciolosis hepatica and dicrocoeliosis dendriticum were 3.99% and 23.55% in sheep, and 0.48% and 2.65% in cattle respectively. No changes in livers, which led to the partial or total condemnation, were observed.

This study was carried out on cows, sheep and goats in Salkaya Village, Kovancılar, Baskıl and Sivrice towns and in Elazığ during 1994 and 1995. Fifty two myiasis cases were detected throughout the study. Forty seven (90.38%) and 5 (9.62%) of the cases were determined in sheep and cows respectively, no myiasis case was encountered in goats. Twenty two (42.32%) of the cases were seen in June during 1994 and 1995, 10 (19.23%) in May, 9 (17.31%) in July, 8 (15.38%) in September and 3 (5.77%) in August.

Summary : This research was carried out to compare the fertility traits, greasy fleece weight and wool characteristics in breeding ewes; and the growth and survival rates of lambs in Ankaraman and Malya breeds. The data was obtained for fertility traits from 5581 Malya and 9707 Akkaraman ewes, for growth rates from 100 lambs in each breed, for greasy fleece weights from 100 ewes in each breed and for wool characteristics from 32 Malya and 28 Akkaraman ewes. Fertility traits such as lambing percentage, twinning rate, litter size and number of lambs weaned per hundred ewes lambing between 1992 and …

The animal material of the research was 3, 4 and 5 years old 210 Merino ewes and their lambs. The research was started at the beginning of the last 1.5 months period of gestation and continued until the lambs were reached 60 days age. It has been determined that 500 g and more (especially 1500 g) concentrate feed given fed ewes daily at the last 1.5 months period of gestation increased the liveweight and decreased the weight loss of ewes and increased birth weight, growth and survival rates of lambs.

In this study, the etiology of ovine and caprine abortions was investigated bacteriologically, serologically and pathologically. Tissue samples collected from aborted sheep and goats in Elazığ and its borders were examined bacteriologically and pathologically for brucellosis, campylobacteriosis, salmonellosis and listeriosis. In addition, blood samples collected from aborted sheep and goats were examined by serological tests for the presence of antibodies to these bacteria. Of 110 aborted fetuses, in 22 (20%) Brucella melitensis, in 5 (4.5%) Campylobacter fetus subsp. fetus, in 4 (3.6%) Salmonella abortus ovis, in 1 (0.9%) Listeria monocytogenes and in 3 (2.7%) E. coli were isolated and identified. …
