| description | Antibacterial preparations are used to prevent bacterial diseases in poultry when raising broilers but given the negative factor of their residual accumulation in meat and the acquisition of resistance by pathogens, it became necessary to find alternative means. The purpose of this study was to determine the effectiveness of various concentrations of Bacillus coagulans on the growth and development of broiler chickens. Methods employed: microbiological; physiological to determine the state of health and safety of chickens; zootechnical; pathological; statistical. The chickens in the experiment had a higher live weight at Day 35: in Group 1 – by 11%, in Group 2 – by 15.4%, and in Group 3 – by 18.4%, as opposed to the control. The average daily body weight gain of chickens in groups with B. coagulans was higher, in Group 1–by 10.8%, in Group 2–by 15%, and in Group 3–by 18.3%. The preservation rate in all experimental groups, regardless of the probiotic concentration, was 100%, while in the control group – 80%. There was an increase in live weight in the following groups: Group 1–by 11%, Group 2 – by 15.5%, Group 3 – by 19%. Feed conversion was lower in Group 1 by 5.3%, in Group 2 – by 3.4%, and in Group 3 – by 2%, compared to the control. At the end of the study, the level of Lactobacillus sp. in the intestines of chickens in Group 1 was 33.78% higher, in Group 2 – by 50%, in Group 3 – by 78.37%; a decrease in the content of Enterobacteriaceae sp. in Group 1–by 51.48%, in Group 2 – by 65.11%, in Group 3–by 90.67%; Staphylococcus sp. in Group 1–by 15.04%, in Group 2–by 35.44%, in Group 3–by 51.47% (p≤0.05), in contrast to the control. The average bursal weight in Group 1 was 4.82% higher, in Group 2–30% higher, in Group 3–37.53% higher, and the bursal index was 15%, 25%, and 30% higher, respectively, compared to the control |
