Some observations on the possible nutritional significance of vitamin BIZ - and folate - binding proteins in milk
I . The folate and vitamin BIZ in milk are strongly bound to minor whey proteins. These binder proteins are present in excess, and so milk has capacity which varies between milks of different mammalian species to sequester added cyanocobalamin and folic acid. 2. A study was made of the influence of different milks on uptake of [sH]cyanocobalamin and [’Hlfolic acid in selected bacteria, mostly o...

متن کاملBioavailability of vitamin B₁₂ in cows' milk.
The natural source of vitamin B₁₂ in human diets comes from animal products. For example, one glass (250 ml) of milk provides approximately 50 % of the RDA (2·4 μg/d). It was hypothesised that the provision of vitamin B₁₂ from milk is more efficiently absorbed than the synthetic form used in vitamin supplements. Pigs (n 10) were used as a model for intestinal absorption of vitamin B₁₂ in humans...

Background and purpose: Lactoferrin is a multifunctional protein, which is useful for clinical and commercial applications. Recently it has been shown that ingestion of Lactoferrin has advantages including: immune system modulation, anti-microbial activity and antioxidant in neonates and adults in both animals and humans. The present study has been conducted with the purpose of isolation and op...
متن کاملEffect of butaphosphan and cyanocobalamin on postpartum metabolism and milk production in dairy cows.
The aim of this study was to determine the effect of butaphosphan and cyanocobalamin (BTPC) supplementation on plasma metabolites and milk production in postpartum dairy cows. A total of fifty-two Holstein cows were randomly assigned to receive either: (1) 10 ml of saline (NaCl 0.9%, control group); (2) 1000 mg of butaphosphan and 0.5 mg of cyanocobalamin (BTPC1 group); and (3) 2000 mg of butap...
