The authors found that the density of colostrum in cows with a homozygous genotype for B allele kappa-casein gene was higher compared to A and had greater amount immunoglobulins by 29.5 mg/l, respectively. formation high colostral immunity calves obtained from mothers genotypes AB BB prevented occurrence diseases gastrointestinal tract, AA reduced colostrum, it led development diarrhea 12% newb...

Kappa-casein is a mammalian milk protein involved in a number of important physiological processes. In the gut, the ingested protein is split into an insoluble peptide (para kappa-casein) and a soluble hydrophilic glycopeptide (caseinomacropeptide). Caseinomacropeptide is responsible for increased efficiency of digestion, prevention of neonate hypersensitivity to ingested proteins, and inhibiti...

The influence of kappa casein genotype on the formation economically useful traits Ukrainian black-and-white dairy cattle has been studied. Genotyping 25 heads black-and white breed belonging to Breeding Plant State Enterprise "Research Farm Institute Agriculture Northern East NAAS" was carried out. Determination polymorphism kappa-casein gene performed in genetic laboratory Bogomolets Physiolo...

Transgenic mice were produced by microinjection of a DNA construct composed of the bovine kappa-casein (kappa-CN) cDNA under the control of the goat beta-CN 5' promoter elements and 3' flanking regions into pronuclear-stage embryos. The gene construct targeted the expression of bovine kappa-CN RNA to the mammary gland and secretion of bovine kappa-CN in the milk. In the three lines studied (BC-...

The aim of the present study was to screen the genotype profile of bovine kappa-casein gene among Frieswal (HF × Sahiwal) crossbred cattle developed in India. A total number of two hundred Frieswal cows were evaluated for HinfI RFLP based genotyping of kappa-casein gene. We observed that only two genotypes (AA and AB) exist among the studied population with the genotype frequency of 0.58 (n=117...
