Article Synopsis
- The study focuses on the role of specific genes related to milk quality traits in Gannan yaks, specifically analyzing the IQ motif containing GTPase activating protein 2 and circulating cartilage acidic protein 1.
- Five significant single nucleotide polymorphisms (SNPs) were identified in these genes, showing a correlation with elevated levels of lactose, milk fat, and total solids in yak milk.
- Mutations at specific loci were found to act as potential molecular markers for improving milk quality, with notable effects on lactose content, milk fat, and total solids in the milk of Gannan yaks.
Article Synopsis
- The tyrosine protein kinase gene, part of the Tec family, and phospholipase C epsilon 1 play crucial roles in signal transduction and muscle differentiation, respectively.
- A study explored the impact of SNPs in these genes on growth traits such as body weight and height in Ashidan yaks.
- Significant correlations were found between specific SNP loci and growth characteristics, suggesting potential molecular markers for improving yak breeding.
Article Synopsis
- - This study investigated the leucine aminopeptidase gene's variations (SNPs) and how they relate to milk quality in Gannan yak, using a sample of 162 animals genotyped with the Illumina Yak cGPS 7K BeadChip.
- - Four SNPs showed polymorphism, with two (g.4494G > A and g.5919A > G) linked to higher protein content, while another (g.8033G > C) was associated with casein and other milk components.
- - The findings suggest that these genetic variations positively influence milk quality traits, highlighting the potential of using this gene as a marker in breeding programs for better milk production in G
The widespread environmental contamination resulting from the misuse of tetracycline antibiotics (TCs) has garnered significant attention and study by scholars. Photocatalytic technology is one of the environmentally friendly advanced oxidation processes (AOPs) that can effectively solve the problem of residue of TCs in the water environment. This study involved the synthesis of the heterogeneous magnetic photocatalytic material of CoFeO/NaBiO via the solvothermal method, and it was characterized using different characterization techniques.

Compared with cow milk, yak milk contains higher levels of nutrients such as dry matter, milk fat, and milk protein, which demonstrates great potential for exploitation and utilization. Protein kinase cGMP-dependent 1 () is an important functional molecule in the cGMP signaling pathway, and its significant influence on milk fatty acids has been discovered.

- The study explores how specific gene variants (SNPs) of certain potassium channels affect the milk quality traits in Gannan yaks, particularly focusing on components like lactose, fat, and protein levels.
- Research utilized advanced genetic techniques to identify three new SNPs in the genes of lactating female yaks, linking these variants to improved milk composition.
- Results indicate that particular mutations in these genes are associated with significant enhancements in lactose, milk fat, casein, and other quality metrics, suggesting their potential as targets for future breeding programs aimed at improving milk quality in Gannan yaks.
Yak () is a unique large ruminant species in the Qinghai-Tibetan Plateau (QTP). Changing the energy levels of their rations can significantly improve their growth performance. Therefore, studying the effects of dietary energy levels on the rumen microflora and metabolites of yak is crucial for enhancing the development of the yak industry.

- The study investigates the coiled-coil serine-rich protein 1 gene's role in determining milk quality traits in Gannan yaks through single nucleotide polymorphisms (SNPs).
- The research involved genotyping 172 yaks and analyzing how three specific SNP loci influenced milk traits such as fat, protein, and casein content.
- Findings show that certain gene mutations significantly enhance milk quality, suggesting these SNPs could serve as molecular markers for breeding better milk-producing Gannan yaks.
This study aimed to investigate the nutritional properties of yak milk in various areas of Gannan. The milk composition analyzer, automatic amino acid analyzer, and flavor analyzer were used to detect the conventional nutrients, amino acids, and volatile flavor substances of 249 yak milks in Meiren grassland, Xiahe grassland, and Maqu grassland (hereinafter referred to as Meiren yak, Xiahe yak, and Maqu yak) in the Gannan area. The results showed that the fat content of Meiren yak milk was significantly higher than that of Maqu yak and Xiahe yak ( < 0.
