The vitamin C content of cow's milk

The effect of feeding cacao shell to cows on the vitamin D content of butter (milk).

IT has recently been reported by Knapp and Coward [1934] that cacao shell, an important by-product of chocolate manufacture, is rich in vitamin D. The sample examined by them contained 28 International Units (i.u.) per g. and was therefore about one-quarter as potent as an average cod-liver oil. For a vegetable product the potency is quite exceptional. As cacao shell is mainly used in cattle fo...

Bioavailability 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...

Vitamin content of camel milk.

The content of vitamin C, vitamin B2 and fat-soluble vitamins E and A in camel milk was studied. The milk samples were collected from 20 individual camels (Camelus dromedarius) in two different occasions. The study showed that camel milk contains considerably less vitamin A and B2 than cow milk while the content of vitamin E was about the same level. The level of vitamin C was in average three ...
