thriteen thousand, seven hundred and fifty two (13752) records on growth tarits (birth weight, 1, 3, 6, 9 and 12 month weights) as well as pelt scores, collected during 1996-2002 as karakul sheep breeding station, sarakhs, iran were employed in this study. best liner unbiased prediction (blup) of breeding values, genetic and phenotypic trends of the traits were estimated as the regression of av...

Twenty Karakul rams were allotted to four groups, subjected first to starvation and then allowed restricted amounts (approximately 1/3 of ad l ib i tum intake) of a high fiber, low energy diet containing no additive (control), 5% 1,3-butanediol (BD), 10% BD, and 5% 1,2-propanediol (PD) for 6 weeks. Starvation elevated (P<.O01) serum ketones (3-hydroxybutyrate and acetoacetate) and decreased (P<...

Abstract Farm diversification is mainly driven by risk mitigation effects and economic gains related to complementarities between production activities. By combining these two aspects, we investigate economies in a sample of French mixed sheep farming systems rank using stochastic dominance criteria. Partially diversified (Sheep-Grass, Sheep-Crop, Sheep-Landless) fully (Sheep-Grass-Crop-Landles...

The seasonal incidence of gastro-intestinal helminths and of Oestrus ovis was determined by slaughter of successive groups of 4 tracer lambs, each exposed on pasture for 33 days. Haemonchus contortus was present from March 1979 to early July 1979, with a generally increasing percentage of 4th stage larvae in each successive month. A "spring rise" in the egg count was seen in flock sheep in Octo...
