USE OF PROBIOTICS WITH CHITOSAN AT CULTIVATION OF CALFS
In order to study the effect of probiotic feed additive “Mutsinol Extra” containing chitosan, on the functional state of the organism defense mechanisms, morphological and biochemical blood indices and average daily gains of live weight of calves was conducted of experience in calves black - motley breed 2 - 2.5 months of age with a average live weight of 73,62 ± 1,32 kg. Taking into account the breed, age, body weight, physiological state identity were formed 3 groups of calves on 20 goals each. Animals of the first group was the control, the second group of calves received a probiotic “Mutsinol Extra” 1 time per day to 7 g / head. for 10 days, the third group - 7 g / head. for 20 days. According to the data, desoldering 2 - 2.5 months of age for 10 days probiotic “Mutsinol Extra” led to the optimization of mikrobiotsinoza colon, as indicated by the pronounced tendency to increase the number of Bifidobacterium, Lactobacillus, Escherichia typical and fewer klostrudy fat contents intestine. Watering of the drug for a longer period (20 days) had no significant effect on the studied indicators, but created the conditions that exclude Candida growth in the intestinal contents. Hematological parameters calves experimental groups throughout the experimental period did not exceed the standard values with no significant between-group differences. Calves third group noted a pronounced tendency to increase the level of white blood cells after watering “Mutsinol Extra” of the drug for 20 days, indicating an increase in the body’s defenses. The highest weight gain in calves of all groups was observed in the first 11 days of the test period without significant intergroup differences significantly. Reliably significant differences in the magnitude of the average daily weight gain were observed after 30 - 40 days after the end of watering preparation. During this time, the average daily gains of live weight of calves 2 and 3 groups were significantly higher than that of the control animals at 37.33 and 11.96%, respectively. Over the next decade the test period the average daily gain of live weight of calves was higher than that of the control animals at 43.33 and 36.67%, respectively, followed by significantly higher average daily live weight gains compared to the control animals were only the second group (34, 25%). Gross weight gain of the test period and the average daily gain for the entire test period was also significantly higher compared to the control calves 2 gruppy.Vypaivanie the drug for 20 days had no significant effect on the gross and average daily gain of live weight for the entire test period.
