THE PIGS BALANCE OF NITROGEN AND PHOSPHORUS DEPENDING ON THE SATURATION OF THEIR DIETS WITH ALFALFA GRASS

The calculations in different periods of the experiment showed that the digestibility of such nutrients as dry matter, nitrogen-free extractive substances is almost unchanged when the content of alfalfa grass in the diets of experimental animals have increased. However, there is a slight decrease in the protein and fiber digestibility ratios (the difference is unlikely). The lowest coefficients of fat digestibility were during the second period of the experiment (difference is unlikely). It may be explained by the adaptive restructuring of the digestive processes in the small intestine.
Balance of nitrogen characterizes transformation of protein substances in animal bodies. The nitrogen balance determines the gain or decrease of protein in the animal body during the experimental period.
If feeding involves an increase in the weight of the animals, part of the nitrogen is deposited in the animal bodies. Mud nitrogen, urine nitrogen and deposited nitrogen is equal to the feed nitrogen.
Conducting the experiment to determine the digestibility of nutrients in pigs, depending on the saturation of their diets with alfalfa grass, positive indicators were found that characterize the use of animal nitrogen in the diet. So, at 4.9% of the alfalfa protein content in the total protein of the diet of experimental pigs, 41.3% of the feed taken from the feed or 51.6% of the digested nitrogen was retained in their bodies.
Phosphorus metabolism is closely linked to protein metabolism. The saturation of pigs' diets in the feeding of alfalfa grass did not adversely affect their absorption of phosphorus.
The smallest amount of phosphorus from feed was maintained in the body of animals in the third period, when the amount of alfalfa added to the diet was highest.
Studies have shown a positive effect on pig productivity when alfalfa grass was introduced in summer rations up to 20% by protein or 16% by dry matter.
