Phenotypic characterization of rambouillet sheep expressing the callipyge gene: I. Inheritance of the condition and production characteristics.

Phenotypic characterization of Rambouillet sheep expressing the callipyge gene: II. Carcass characteristics and retail yield.

Paternal half-sibling Rambouillet ram lambs (n = 18) representing two muscle phenotypes were slaughtered at 54.5 kg to evaluate carcass characteristics and composition. Lambs were produced from a sire that was heterozygous for the callipyge gene. Carcasses were broken into wholesale and retail cuts to evaluate percentage bone-in retail yield of carcasses at various fat trim levels and percentag...

Phenotypic characterization of rambouillet sheep expression the callipyge gene: III. Muscle weights and muscle weight distribution.

Paternal half-sibling Rambouillet ram lambs (n = 18) representing two muscle phenotypes were slaughtered at 54.5 kg to evaluate the effect of the callipyge gene on muscle mass. Lambs were produced from a sire that was heterozygous for the callipyge gene. Nineteen muscles were dissected from the right side of each carcass to evaluate muscle weights relative to carcass weight. Excised muscle mass...

Indigenous Sheep Production in Ethiopia: A Review

Research results and facts of indigenous sheep production were reviewed with the aim of delivering relevant information for the beneficiaries. The common production system used in Ethiopia was the extensive type, which was characterized by small flock sizes and the flock being periodically devastated by diseases. Some indigenous sheep groups of the country were characterized and their names wer...

Microsatellite Polymorphism in DRB2 Gene and its Relation to Haemonchus Contortus Parasites Fecal Egg Count in Iranian Ghezel Sheep

Gastrointestinal parasites are one of the main sources of economic decline in sheep production around the world. Resistant sheep do not completely reject the disease; they only harbor fewer parasites than susceptible sheep and therefore have a lower fecal egg count. The present research was designed to evaluate microsatellite polymorphism in intron 5 of DRB2 gene and its correlation with H. con...
