Summary

Biopreparations obtained from organs and tissues of health animals have the most important significance for increasing of young pigs resistance. Ferments, tissue preparations and pancrease extracts, blood and lymphogenous preparations, organic acids and provitamins are widely used all over the world. Experiments are currently underway in our country to investigate use of hormone substances synthesized by endocrine cells of intestine, stomach and pancreas. Influence of these preparations on fattening qualities and meat productivity indices of meat types- fast-growing meat type of the Steppe breed and the Don type of the North Caucasion pig breed; evaluation of animal on resistance in use of these preparations; study of influence of intestine polypeptides on fattening and meat qualities of DM-1 and ST; developing of methods of increasing pig productivity is ascertained. Experiments were carried out with three preparations keeping intestinal polypeptides: "Extract of piglet duodenum", "Enterdon", "Gastrin, sekretin, cholecystokinin-pancreosimin". The first preparation was given with drinking water, the second one with feed, the third one by injection. It was found out that the first two preparations have better results for increase of pig fattening and meat qualities.

Key words: fattening and meat qualities of pigs, intestinal polypeptide, gastrin, secretin, cholecystokinin.
