Abstract
Relevance. The use of feed additives in the diet of young sheep allows for better absorption of the components of the feed consumed.
The aim of the study was to investigate the effect of the feed additive “Levibio” on the growth, development and clinical parameters of young sheep.
Methods. Generally accepted research methods. Generally accepted research methods (determination of body weight, external measurements and indices, clinical condition, clinical and biochemical blood parameters of young sheep). The “Levibio” feed additive contains live yeast Saccharomyces cerevisiae, which stimulates the growth of beneficial microflora in the rumen of ruminants.
Results. The greatest positive effect of the feed additive “Levibio” on the implementation of meat productivity in young Romanov sheep is observed at the end of the 3rd month from the beginning of its use. The average live weight of the sheep in the experimental group was 32.44±1.37 kg, which is 5.19% higher than that of the sheep in the control group. Linear measurements of the experimental group animals showed that they were larger in chest girth by 2.2%, height at the withers by 4.5%, height at the sacrum by 2.9%, than their counterparts in the control group. Body constitution indices showed compactness and proportionality of the constitution of animals in the experimental group. Hematological studies conducted during the experiment did not reveal any deviations from the physiological norm. Thus, according to our research, the use of the “Levibio” supplement in feeding young sheep allows for better realization of the genetic potential, expressed in more uniform growth and development, live weight gain, health maintenance, and adaptation to the unstable monsoon climate of Primorsky region.
Supporting agencies: The study was conducted as part of the scientific research of the Ministry of Science and Higher Education of the Russian Federation on topic No. 122022600068-5.
