SITUATION OF RESEARCH ON APPLYING COMPONENTS INSTRUCTIONS IN ASSESSMENT OF PIG BREEDING MODELS

Abstract

The study aims to overview the application of molecular markers in the evaluation of pig breeding models. Specifically, we reviewed the GH (grow hormone) gene in pigs and the relation of the GH gene to growth in pigs. Growth hormone (GH), a single-chain polypeptide hormone secreted by the pituitary gland from animals, plays an integral role in the growth and metabolism of the body by regulating carbohydrate, lipid metabolism. and protein. In pigs, the GH gene is located in chromosome 12, with a total transcription length of 1.7kb, containing approximately 2231bp. CAST gene marker (capastatin) is implicated in meat quality in pigs. In pigs, the CAST gene is located on chromosome 2, about 160kb in length. CAST gene polymorphism affects meat quality and bar performance. The FUT1 indicator gene has been implicated in pig immunity. In pigs, the alpha-1-fucosyltransferase (FUT1) gene is located on chromosome 6q11, with a total transcription length of 3315bp. The FUT1 gene can modulate the plasma metabolic system and specific plasma metabolites involved in intestinal microbial metabolism (hippuric acid, oxindole, betaine).
