As a country with not only significant production potential but also fragmented land ownership, the Kyrgyz Republic struggles environmental efficiency, which is strategic element of management in agricultural production. The objective this study was to assess efficiency sheep’s wool when used as fertilizer bean northern Kyrgyzstan. In study, indicator taken be GHG emissions per functional unit ...

In this article, live weight and body size parameters of hybrid lambs obtained from inbreeding F2 sheep with Hisar native breed genotypes were higher than those pure lambs. These results showed that improvement selection traits using rams is great scientific practical value. The the was 5.62 kg at birth, females 5.17 kg, respectively. group I, 0.45 or 8.7%, 0.34 7.2% purebred heifers. However, ...

Factors affecting ewe prolificacy (number of lambs born per ewe lambing) were evaluated using records on 9705 Targhee, 12,721 Suffolk, and 7231 Polypay lambings from flocks participating in the US National Sheep Improvement Program. Factors considered were ewe age and season of lambing. Prolificacy was affected by age of the ewe (P<0.001) and was highest for ewes lambing between 4 and either 7 ...

Abstract We conducted a meta-analysis to evaluate the effects of dietary supplementation dry distillers grains with solubles (DDGS) on performance, fermentation, carcass characteristics, and nitrogen efficiency in meat sheep. A total 36 peer-reviewed manuscripts from 1997 2021 met inclusion criteria for analysis. Data 940 sheep (29.1±11.5 kg) were used estimate magnitude effect between DDGS con...

Brown and Maniatis are also recognized for their extraordinary commitment and generosity in promoting the careers of young scientists. The impact of ...

Between 1996 and 1998, a total of 2,494 samples of blood from humans and animals were collected and tested for brucellosis. This total included 1,594 samples of animal blood, collected from 1,050 sheep from 20 flocks, and 544 goats from eight herds. The serum samples were tested using the Rose Bengal test, the tube agglutination test, the complement fixation test and an enzyme-linked immunosorb...

Two experiments were conducted to determine the effectiveness of a rumen-protected CLA (pCLA) supplement and the impact of feeding this pCLA on carcass characteristics and tissue fatty acid composition of lambs. In Exp. 1, a CLA-80 preparation (80% pure CLA; contained similar proportions of cis-9, trans-11, and trans-10, cis-12 CLA), protected against rumen degradation, was fed to sheep, and th...

Serum samples from 697 Rocky Mountain bighorn sheep (Ovis canadensis) from North America were examined for antibodies to Toxoplasma gondii by the modified agglutination test incorporating mercaptoethanol and formalin-fixed tachyzoites. Antibodies to T. gondii were found in 25 of 697 (3.6%) sheep in titers of 1:25 (8 sheep), 1:50 (4 sheep), 1:100 (7 sheep), 1:200 (1 sheep), 1:400 (1 sheep), 1:80...
