The different types of P in modified caseins and the role of P in casein interactions were studied using 31P nuclear magnetic resonance spectroscopy of whole casein with reduced or elevated P concentrations and using Fourier transform infrared spectroscopy of whole casein with elevated P concentrations. Bovine whole casein (5.7 mmol of P/mmol of casein, 100% P) was either enzymatically dephosph...

background: genetic polymorphism of milk proteins has been associated with composition, manufacture, and traits of milk. caseins are the most important milk proteins whose genes are strongly linked and inherited as a raceme. κ-casein which is a quantitatively minor constituent of bovine milk is thought to play a critical role in organization, fixation and aggregation of casein micelles and firm...

three multiparoys lactating sannen dairy goats in midlactation with mean milk production and dim pf 1.5 ±0.22 kg and 167±4 days were used to determine effects of the abomasal infusion wheat starch, wheat starch or cottonseed oil with casein on performance of sannen dairy goats. goats were fed ad libitum with basal diet include, 40% hay alfalfa and 60% concentrate. treatments were abomasal infus...

Beta-casein (β-CN) is a major dairy protein subject to preferential degradation during storage. Our study aimed isolate β-casein from bovine milk under dissociative conditions by the electrophoretic technique using Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) and optimize an immunochemical such as Mancini radial immunodiffusion in order monitor evolution of this For purp...

The effect of the ingestion of myo-inositol hexaphosphate (IP6) and phytase (EC 3.1.3.26) on the digestibility of casein was investigated using growing broiler chickens. A total of 64 female Ross broilers were used in a precision feeding study. One group of 8 birds was fed a solution of glucose to estimate endogenous losses. Seven groups, each of 8 birds, were fed either casein, casein + 1,000 ...

Malnutrition, particularly protein undernutrition, contributes to the occurrence of osteoporotic fracture by lowering bone mass. In this study, the effects of dietary protein on bone mineral density and body weight in protein undernutrition were compared between gelatin and milk casein. When mice were fed for 10 wk with a low protein diet containing 10(%) casein or 6% casein +4% gelatin, there ...

A new type of cow’s milk, called A2 has appeared in the dairy aisles supermarkets recent years. Cows’ milk generally contains two major types beta-casein as A1 and types, although there are 13 genetic variants ?-casein: A1, A2, A3, A4, B, C, D, E, F, H1, H2, I G. Studies have shown that ?-casein may be harmful, is a safer choice for human health especially infant nutrition health. The cow repor...
