Considerable potential exists to improve lambing performance traits in sheep through breeding

ANALYSIS & COMMENTARY Despite Obstacles , Considerable Potential Exists For More Robust Federal Policy On Community

The implementation of the Affordable Care Act of 2010 and the Obama administration’s urban policy create an opportunity to link community development with health in new and powerful ways. The administration’s policy emphasizes improved access to and quality of care through coordinated local and regional approaches, expansion of access to healthy food, and the support of environmental health—inc...

Risk factors associated with lambing traits.

The objective of this study was to establish the risk factors associated with both lambing difficulty and lamb mortality in the Irish sheep multibreed population. A total of 135 470 lambing events from 42 675 ewes in 839 Irish crossbred and purebred flocks were available. Risk factors associated with producer-scored ewe lambing difficulty score (scale of one (no difficulty) to four (severe diff...

Effect of weaning age on hair sheep lamb and ewe production traits in an accelerated lambing system in the tropics.

This study was designed to evaluate the impact of weaning age on lamb and ewe productivity in an accelerated lambing system. St. Croix White (STX) and Dorper × St. Croix White (DRPX) lambs were assigned at birth based on breed, gender, and litter size to be weaned at 63 (Early-1; 106 lambs and 68 ewes) or 90 d of age (Late-1; 99 lambs and 60 ewes) in Exp.1 or at 63 (Early-2; 77 lambs and 57 ewe...

Application of myostatin in sheep breeding programs: A review

Myostatin or growth and differentiation factor 8 (GDF8), has been known as the factor causing double muscling phenotypes in which a series of mutations make the myostatin protein inactive, hence disabling it to regulate the deposition of muscle fibre. This phenotype happens with high frequency in a breed of sheep known as the Texel. Quantitative trait loci (QTL) studies show that a portion of t...
