Abstract
The scientific article presents the results of studying the effect of the use of betaine in the form of a feed additive "Betacorm" on productivity, nonspecific resistance and peroxide oxidation in roosters of the CM 7 line of the "Shift 9" cross in conditions of limited feeding. Day-old progenitor chickens were selected and 2 groups (experimental and control) of 20 heads each were formed. The duration of the experiment was 38 days. The experimental group was included in the diet of the additive "Betacorm" of domestic production, containing 32% betaine, in the amount of 2 g / kg of feed from the age of ten days, gradually reducing the rate of daily feed intake. The chickens were raised in vivarium conditions in VIVIP. . On the 38th day of life, under conditions of limited feeding, in the experimental group receiving betaine, there was an increase in body weight by 5.6%, an average daily gain of 5.7%, as well as a decrease in feed conversion by 5.7%. The assessment of nonspecific resistance showed a tendency to improve the morphological composition of blood and an increase in the bactericidal activity of blood granulocytes by 15.3%. The use of betaine in the diet of chickens contributed to a significant decrease in the level of malondialdehyde by 15.5%. In the study of biochemical parameters of blood plasma (Table. 5) the chickens of the experimental group showed a tendency to increase the amount of total protein and albumin by 4.4% and 7.3%, calcium and phosphorus by 2.5% and 16.8%, as well as a decrease in the activity of aspartate aminotransferase by 3.6%. The results obtained indicate the beneficial effect of betaine in the diet on the health of chickens. An improvement in nonspecific resistance, an increase in productive indicators, bactericidal activity of granulocytes and biochemical parameters of blood were found.
