Globally, there are approximately one billion beef cattle, and compared with poultry and
swine, beef cattle have the poorest conversion efficiency of feed to meat. However, these …

South American beef production varies due to diverse climates, environmental conditions,
animal breeds (Bos indicus, Bos taurus and crossbreeds), management strategies, and …

Background It has been challenging to implement genomic selection in multi-breed tropical
beef cattle populations. If commercial (often crossbred) animals could be used in the …

Ningxiang pigs are a renowned indigenous pig breed in China, known for their meat quality,
disease resistance, and environmental adaptability. In recent decades, consumer demand …

Background Heterosis has been suggested to be caused by dominance effects. We
performed a joint genome-wide association analysis (GWAS) using data from multi-breed …

Background SNPs are informative to estimate genomic breed composition (GBC) of
individual animals, but selected SNPs for this purpose were not made available in the …

An objective of commercial beef cattle crossbreeding programs is to simultaneously optimize
use of additive (breed differences) and non-additive (heterosis) effects. A total of 6,794 …

The objective of the present study was to quantify the association between both pedigree
and genome-based measures of global heterozygosity and carcass traits, and to identify …

This study evaluated the effects of three genomic indicators of heterosis on female fertility
and lifetime productivity, and quantified changes over 11 production cycles in a crossbred …

The Brangus cattle were developed to utilize the superior traits of Angus and Brahman
cattle. Their genetic compositions are expected to be stabilized at 3/8 Brahman and 5/8 …
