Genome-Wide Association Study of Body Measurement Traits at Birth in Cattle

Hexi cattle are an indigenous beef breed developed through multigenerational crossing of Simmental and Mongolian cattle, exhibiting exceptional adaptability to arid and semi-arid environments alongside robust growth performance. To investigate the genetic architecture underlying...

Genetic Variation and Haplotype Structure of CFAP299 and PRDM8 Associated with Fiber Yield and Hair Length Traits in Tianzhu White Yak

Fiber yield and hair length are important economic traits in Tianzhu White Yak. However, the genetic variants associated with fiber production performance in this breed remain insufficiently characterized. This study aimed to investigate the associations of single nucleotide poly...

Preventive Effects of Fermented Yak Milk-Derived Lacticaseibacillus paracasei CD12-1 Against DSS-Induced Colitis in Mice

Ulcerative colitis is a chronic inflammatory bowel disease characterized by mucosal barrier disruption, dysregulated immune responses, and gut microbial imbalance. However, limitations of current therapies highlight the need for safe probiotic interventions. This study evaluated...

Genome-Wide Association Study and Genomic Selection for Average Daily Gain in Ashidan Yak

Average daily gain (ADG) is a core quantitative trait determining the economic benefits of Ashidan yak, a polled new breed adapted to cold barn feeding on the Qinghai–Tibet Plateau. Unraveling its complex genetic architecture is crucial for early molecular breeding selection. In...
