The influence of technological improvement of the methods of providing complete nutrition of pigs on biochemical indicators of blood
Abstract
The results of the influence of the developed balancing feed additives in the composition of small - component compound feeds made on the developed unit on the morphological and biochemical composition of the blood of piglets are highlighted. The study of the effectiveness of the use of balancing additives in the composition of small-component feed produced on the developed unit, was carried out in experimental studies to determine their productive effect on the main economic and useful characteristics of piglets on rearing. The recipe of the developed balancing additives and compound feed on the basis of a grain part from wheat and barley was carried out in production conditions on piglets of breed Welsh (2-4 months) with live weight from 20 kg to 40 kg on balanced rations on all nutrients: protein, carbohydrates, fats, minerals, vitamins, enzymes and others. The experimental groups of piglets differed in the grain part of the feed and the developed composition of BVMD for each group separately: I experimental group - barley + BVMD №1, II experimental - barley + wheat + BVMD №2, III experimental - wheat + BVMD №3, IV control - on economic diet based on barley grits. The results of the study of protein and protein fractions of blood indicate that the change in the level of total protein in the blood is observed in all groups only with age and corresponds to the physiological norm, without significant differences between experimental and control animals. At 2 months of age, the content of total protein in the serum was at the level of 6.21 g% to 6.69 g% with an incredible difference between the groups. Compared with him, at 4 months of age, he increased from 6.34 g% to 7.25 g%. There was a tendency to increase the content of albumin, alpha, beta and gamma globulins with age in all groups. The results of the study of lysozyme activity showed a decrease with age in groups I and II in 0.88 times and 0.93 times and an increase in groups III and IV in 1.04 and 1.28 times. The probable difference in lysozyme activity was in 2 months of groups I and III at P> 0.90 compared with the control. The obtained data on the morphological and biochemical composition of the blood of piglets when grown in terms of hemoglobin and erythrocytes showed that a more productive group of animals tended to increase. Age changes of other indicators corresponded to a physiological condition and did not go beyond physiological norms. Indicators of protein fractions and opsono-phagocytic reactions.
