Influence of probiotics on growth dynamics and blood parameters of Zaanen goats

Abstract

Relevance. In the prevention and treatment of gastrointestinal diseases in the rearing of young animals, the restoration of intestinal biocenosis with the use of probiotics — bacterial preparations from live microbial cultures is of great importance.The purpose of the research is to study the effect of probiotic feed additives Klyuver Pro and BeneFIT Basic on growth dynamics, feed costs and blood parameters of Saanen goats.Methods. The studies were carried out at LLC «Lukoz Saba» of the Sabinsky district of the Republic of Tatarstan. The object of the study is the kids of the Saanen breed at the age of seven days. Scientific and economic experience was carried out according to the method of analogues. The chemical composition and nutritional value of feed, the dynamics of changes in live weight, the morphological and biochemical parameters of the blood of goats were studied. Statistical data processing was carried out using Microsoft Excel. A difference of p ≥ 0.05 was considered significant.Results. Probiotic feed additives Kluver Pro and BeneFIT Basic activate metabolic processes in the body of kids, increase the digestibility and assimilation of feed, which has a positive effect on the growth and development of animals, and reduce feed costs. The live weight of goats treated with probiotics increased (compared with the control) by 7.7% (p ≥ 0.05) and 3.6%. Feed costs decreased per 1 kg of live weight gain decreased by 13.6% and 10.1%.In the blood of animals treated with probiotics, there was an increase in hematocrit, hemoglobin and erythrocytes. In animals of the second group, these indicators increased by 17.4%, 31.7 g/l (39.3%) (p ≥ 0.001) and 4.45 ˟ 1012/l (77.1%) (p ≥ 0.001), in animals the third group — respectively, by 7.5%, 7.7 g / l (9.5%) (p ≥ 0.001) and 1.63 ˟ 1012/l (28.2%), as well as a significant decrease in ESR — by 0, 37 mm/g and 0.18 mm/g (p ≥ 0.001), calcium content by 20% and 24.2% (p ≥ 0.05).
