Vitamin D 3 is already found early in the evolution of life but essentially as inactive end
products of the photochemical reaction of 7-dehydrocholestol with ultraviolet light B. A full …

The function of vitamin D in calcium homoeostasis in dairy cows, such as in other
vertebrates, is known for many years. In recent years, new and interesting, non-classical …

In this paper, we present a review of the current knowledge of calcium and phosphorus
metabolism as it relates to homeostatic mechanisms in poultry; contrasts with mammalian …

Although vitamin D is critical to calcium/phosphorus homeostasis, bone formation and
remodeling, there is evolution-based variation between species in vitamin D metabolism …

The demand for vitamin D analysis in veterinary species is increasing with the growing
knowledge of the extra-skeletal role vitamin D plays in health and disease. The circulating …

This study evaluated the effect of dietary calcium (Ca) and available phosphorus (aP)
restriction on growth performance, nutrients retention (ATTR), serum metabolites, and tibia in …

In dogs, optimal growth is critical for future health and wellbeing. Recently, a series of
evidence-based growth standards, based on bodyweight, were developed for male and …
