Sample text

In adults, bones demineralize and become fragile (osteomalacia). Recent studies have shown that vitamin D 3 (cholecalciferol) is only a prohormone activated by hydroxylation in the liver and kidneys. The resultant molecule (1,25-dihydroxycholecalciferol) acts as a true hormone in a number of target organs (intestine, bone, kidney, parathyroid gland); its synthesis is controlled by feedback mechanisms (negative) and to a greater or lesser extent by calcium absorption. Vitamin D2 (ergocalciferol) has no activity in birds.

Vitamin requirements and diet formulation 33 By virtue of intestinal synthesis, the need for dietary levels of vitamin K is only really necessary in rabbits and pigs during the first few weeks of life. On the other hand, it is important to add vitamin K to all diets for poultry due to the short length of the digestive tract in this species and their rearing conditions which reduce coprophagy. The recommendations given for each system of production account for an increase in requirements in those suffering from coccidiosis.

Vitamin B 2 is abundant in milk products, certain plant materials (lucerne) and animal meals but is found only at low levels in seeds and, consequently, it is important to include it in typical diets based on cereals and oil meals. Riboflavin is unstable only in the presence of light and is well preserved in raw materials and compound feeds. A relative degree of confidence may therefore be placed in the tables of composition, and supplementation need only be as a precautionary measure, as the vitamin is inexpensive, to give a dietary level of the order of double the minimum requirement.
