The Evaluation of Genetic and Phenotypic Differences Associated with Short Term Selection of Four Different Feed Efficiency Strategies in Japanese Quail
… outputs are desired in a commercial poultry breeding program, resulting in the need for nutrients to be partitioned in a particular manner. At the broadest level, nutrients are partitioned between production and maintenance requirements. The requirements for production and maintenance varies …

Developing Breeding Objectives for Targhee Sheep
Breeding objectives were developed for Targhee sheep at different levels of prolificacy and triplet survival. Economic weights (EW) were derived for estimated breeding values (BV) from National Sheep Improvement Program genetic evaluations for 120 d weaning weight (WW), maternal milk (MM), yearling …

Genetic Parameter Estimates of Milkability Traits in South African Holstein Cattle
… Milkability traits have not been included in the breeding objectives of South African dairy cattle and their genetic parameters in the population have not been estimated. The primary objective of the study was to estimate genetic parameters for milkability traits in South African Holstein cattle. …
