The production traits of cattle, especially milk trait, are of great significance to human life. A quantitative trait loci (QTL) associated with milk fat content was detected in the centromeric region of cattle chromosome 14. This QTL harbors a strong candidate gene called responsible for the milk quality. A non-conservative substitution of lysine by alanine () was found in gene producing a strong effect on milk composition and yield. The lysine (K allele) is associated with increased milk fat content, while the decreased milk fat content is linked to the alanine (A allele) amino acid. To estimate the frequencies of the polymorphism in Chinese cattle breeds, PCR and DNA sequencing methods were used to investigate the polymorphism of in a total of 682 individuals, including 655 Chinese cattle and 27 Holstein cattle. The results demonstrated that the frequency of K allele gradually elevated from the northern group to the southern group of native Chinese cattle, whereas the frequency of A allele showed a contrary pattern, displaying a significant geographical difference across native Chinese cattle breeds. Our results confirm that the southern cattle group has higher milk fat content than that of the northern group.

An acute, often fatal disease caused by the ingestion of milk, milk products, or the flesh of cattle or sheep which have a disease known as trembles. It is marked by weakness, anorexia, vomiting, constipation, and sometimes muscular tremors. It is caused by poisoning by white snakeroot (Eupatorium rugosum) and the rayless goldenrod (Haplopappus heterophyllus). (From Dorland, 27th ed)
Allergic reaction to milk (usually cow's milk) or milk products. MILK HYPERSENSITIVITY should be differentiated from LACTOSE INTOLERANCE, an intolerance to milk as a result of congenital deficiency of lactase.
The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.
The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.
The liquid components of milk that remain after the CASEIN, fat, and fat soluble components have been removed. It is also a byproduct of cheese production.
