Effect of Cattle Breeds on Milk Composition and Technological Characteristics in China

Abstract

Cattle breeds have a striking effect on milk, including milk composition and technological characteristics. This study aims to compare milk composition, acidification activity, viscosity, milk dispersion system stability and casein molecular weight among three buffalo breeds in China. The technological characteristics of milk produced by three cattle breeds of river buffalo (Murrah), crossbreed 1st generation (F1), crossbreed multiple generation (FH, H≥3) buffaloes were investigated. Cattle breeds showed evident effect on milk protein, fat and total solids content, but little effect on most of buffalo casein molecular weight. Milk fat, protein content and the viscosity of buffalo milk from river buffalo were lower than those of F1 and FH, so was the buffer capacity. The viscosity was negatively correlated to temperature and concentration. Results of stability coefficient showed that milk dispersion system had the best dynamic stability characteristics under pH 6.6 and 6 times dilution, while zeta potential of Murrah milk was slightly higher than that of hybrid offspring (F1, FH). SDS-PAGE results showed that buffalo αs-casein had a slightly faster mobility than standard αs-casein; while buffalo β-casein showed a slightly slower mobility than standard β-casein. There is no clear differences in molecular weight of αs-, β-, and κ-casein among Murrah, F1 and FH.

Changes in milk yield and composition of colostrum and regular milk from four buffalo breeds in China during lactation

“…Yang et al . observed a similar band distribution with the same casein fraction identified in Murrah, F1 and F H buffalos . The major protein fractions in casein and whey protein of buffalo milk are αs‐casein (34.38% of total protein) and β‐lactoglobulin (10.5% of total protein), respectively.…”

“…34 Yang et al observed a similar band distribution with the same casein fraction identified in Murrah, F1 and F H buffalos. 35 The major protein fractions in casein and whey protein of buffalo milk are s-casein (34.38% of total protein) and -lactoglobulin (10.5% of total protein), respectively. In comparison, human milk contains neither the s1-fraction nor -lactoglobulin, which are both very abundant in buffalo milk.…”

Evaluation of Milk Colostrum Derived Lactoferrin of Sahiwal (Bos indicus) and Karan Fries (Cross-Bred) Cows for Its Anti-Cancerous Potential

“…The purpose of utilizing colostrum from one native cow and cross-bred cow was based on the fact that genetic makeup of indigenous (zebu) cattle are known to be different compared to exotic cattle. Previous studies have confirmed the differences in milk proteins and their composition in cattle types with a distinct genetic background [1,[25][26][27][28][29].…”

“…However, the differentially originated proteins and their prospective peptides may have altered properties due to the difference in their origin [33]. Differences in the genetic configuration of cattle breeds affect milk yield, composition, proteins and further affect their implications on human health [1,8,36]. Further, it has been reported that different genetic variants of Lf have differed functional properties [25].…”

“…Cow milk is considered as balanced and nutritive food that becomes an integral part of healthy diet. Cow breeds with difference in genetic makeup have a striking effect on milk composition as well as on the nutritional value of the obtained dairy foods [1,2]. Through series of molecular studies, it has been well demonstrated that Bos indicus (zebu) cattle are genetically distinct from their taurine counterparts [3][4][5][6].…”
