When supplementing lamb diets with vitamin E, an equivalence factor of 1.36 is used to discriminate between RRR-α-tocopheryl acetate and all-rac-α-tocopheryl acetate. However, more recent studies suggest a need for new equivalence factors for lives

This study evaluated the biological discrimination of different α-tocopherol stereoisomers (i. e. RRR-, RRS-, RSR-, RSS- and the four 2S-α-tocopherols) from all-rac-α-tocopheryl acetate supplementation in milk replacer for rearing and veal calves

SUMMARY There is an ongoing discussion regarding the relative effectiveness of the hydroxy analog of methionine (liquid MHA-FA) relative to DL-methionine (DLM). Five experiments were carried out under local conditions in 4 different countries to furt

Vitamin D₂ impairs utilization of vitamin D₃ in high-yielding dairy cows in a cross-over supplementation regimen

Autor: L, Hymøller, S K, Jensen

Publikováno v: Journal of dairy science. 94(7)

Vitamin D exists in 2 forms that are important regarding vitamin D status and supply in cattle: vitamin D(2) (D(2)) and vitamin D(3) (D(3)). To become physiologically active, both D(2) and D(3) must undergo 25-hydroxylation in the liver. The resultin

In swine nutrition, little is known about the vitamin D requirements for reproductive processes and bone health. Consequently, the vitamin D recommendation for sows during gestation and lactation is not based on scientific reports. The current study
