NEW PRINCIPLES OF BALANCING OF CALCIUM AND PHOSPHORUS ON MILK PRODUCTION AND EXCHANGE PROCESSES IN THE ORGANISM OF COWS
Abstract
In the basis of balancing calcium requirements for milk production and metabolic processes in the body, the ratio of the use of the raw protein of the diet to milk protein synthesis is laid, which, depending on the level of daily milk yield, is at the level of 20 to 30%. The need for calcium includes the presence of calcium in 1 kg of milk, which is 1.2 grams, as well as the allocation of it with milk in a day's milk yield, that is, the need for milk formation. The total need for calcium for cows of different levels of productivity includes the need for it for milk formation and metabolic processes in the body. In this case, 48 g of calcium are excreted from the cow's body with milk of 40 kg of milk, and 5 g of calcium are contained in muscle tissue and various body fluids, which in total amounts to 53 g of Ca. With a total requirement of 202 g, its digestibility is 21.2%. Thus, the formation of milk requires 185 g or 91.6% of calcium from the total demand and for metabolic processes in the body – only 8.3%. The phosphorus requirement for the production of 40 kg of milk for cows with live weight of 600 kg is 83.3% of the total demand, and for metabolic processes – 16.6%.
