Publikováno v: Small Ruminant Research. 154:81-91

Meat quality and carcass characteristics are becoming more relevant for the sheep breeding programs because of their economic value. Understanding the genetic basis for these traits and its relationship with standard traits is necessary for this to b

Development of an in situ procedure to evaluate the reticulo-rumen morphology of sheep selected for divergent methane emissions

Autor: Ju Zhang, W. E. Bain, John C. McEwan, Vinod Suresh, Stephen J. Waite, Garry C. Waghorn, John Cater

Publikováno v: Animal, Vol 13, Iss 3, Pp 542-548 (2019)

Published studies have shown that methane yield (g CH4/kg dry matter) from sheep is positively correlated with the size (volume and surface area) of the reticulo-rumen (RR) and the weight of its contents. However, the relationship between CH4 yield a
