Nentwich I . , Szépfalusi Zs. , Kunz C. , Spuergin P. , Urbanek R.: Antigenicity for Humans of Cow Milk Caseins, Casein Hydrolysate and Casein Hydrolysate Fractions. Acta Vet. Brno 2004, 73: 291-298. Cow milk casein consists of several fractions each of which have different structure and differing antigenicity. The aim of the study was to investigate the capacity of cow milk casein, casein frac...

Twenty-five wether lambs (34 +/- 0.9 kg) fitted with ruminal and abomasal infusion catheters were used in a completely randomized design to determine the effects of differing proportions of ruminal and abomasal casein infusion on N balance in lambs fed a high-concentrate diet (85% corn grain, 1.6% N; DM basis) for ad libitum intake. Wethers were infused with 0 (control) or 10.4 g/d of N from ca...

Milk and milk components are mainly used for related food products. Nevertheless, some of the milk constituents such as casein have alternative non-food applications. In ancient Egypt caseinbased glue was first used. Milk casein proteins are also used for other technical applications [1] including plastic manufacturing [2], fiber textile [3], methane gas production [4]. Casein proteins in bovin...

In the hormonally responsive 7,12-dimethylbenz(a)anthracene (DMBA)or A/-nitrosomethylurea (NMU)-induced mam mary carcinomas, regulatory mechanisms have been altered such that these tumors retain their hormonal dependence for growth but possess only a limited ability to synthesize the mammary gland-specific milk proteins. Quantitation of casein mRNA levels revealed that very low levels of casein...

The present study is the first to examine the hypothesis that dietary supplementation with beta-casein A1 promotes an increased risk relative to supplementation with beta-casein A2 in patients traditionally at high risk of developing CVD. The study was conducted in fifteen asymptomatic participants (six male; nine female) at high risk of developing CVD. A double-blind cross-over study design wa...

Forty-eight barrows with an average initial body weight of 25.5±0.3 kg were assigned to 6 dietary treatments arranged in a 3×2 factorial of 3 graded levels of P at 1.42, 2.07, or 2.72 g/kg, and 2 levels of casein at 0 or 50 g/kg to compare the estimates of true total tract digestibility (TTTD) of P in soybean meal (SBM) for pigs fed diets with or without casein supplementation. The SBM is the o...

When milk is ingested, casein micelles will be successively digested by pepsin in the stomach and trypsin in the intestine. Therefore, we digested casein micelles successively with pepsin at pH 4.0 and trypsin at pH 7.0, and recovered casein phosphopeptides (CPP) as CPP-calcium phosphate (CP) complexes. The CPP-CP complexes contained 248 mg of calcium/g peptides and 175 mg of inorganic phosphor...
