Because of an increasing interest in crossbreeding between dairy breeds in dairy cattle herds, farmers are requesting breeding values for crossbred animals. However, genomically enhanced breeding values are difficult to predict in crossbred populations because the genetic make-up of crossbred...

In Germany, many autochthonous sheep breeds have developed, adapted to mountain, heath, moorland, or other marginal sites, but breeds imported from other countries have also contributed to the domestic breeds, particularly improving wool and meat quality. Selective breeding and the intense use of...

The role of breed differences in productive traits consider as major genetic resources for enhancing meat quality, quantity and production efficiency. It is important to determine the potential value of carcass traits from breed crosses and breed differences as alternate source of germplasm for...

Currently, enhancing the collaboration between related breeds is of main importance to increase the competitivity and the sustainability of local breeds. One type of collaboration is the development of an across-breed reference population that will allow a better management of local breeds. For...

Interbull's multiple across-country evaluaftion provides national breeding organizations with breeding values for internationally used bulls, which integrate performance data obtained in different breeding populations, environments, and production systems. However, breeding value-based selection...

Southern Multi-Breed (SMB) is a landmark five-year project, collecting high-quality phenotypes and genotypes on animals from six breeds, managed in multi-breed groups at five NSW Department of Primary Industries research herds. Data collected will enhance genetic evaluations and facilitate the...

The objective of the review is to suggest breeding and conservation strategies for the Tikur sheep population. Determination of breeding and conservation strategies for livestock improvement mainly relies on the breed merits of the animals. Tikur sheep are the dominant sheep types in the highlands...

Forward cross-validation analyses were used to quantify the changes in BREEDPLAN EBVs from single-step genetic evaluations compared to traditional pedigree-based evaluations for Angus, Brahman, Hereford, Santa Gertrudis and Wagyu breeds. EBVs were generated from full multi-trait evaluations for...

The specifics of breeding and selection significantly affect genetic diversity and variability within a breed. We present the data obtained from the genetic analysis of 21 thoroughbred and warmblood horse breeds. The most detailed information is described from the following breeds: Arabian,...

Purpose: To discover the breed (lines) characteristics of Peking duck Z9 line, Jingxi hemp duck and Ji'an red feather duck by analyzing the gender and breed difference and also the correlation between body size traits and slaughter performance of three breeds (lines) at 300-day-old. Methods: Peking ...
