Influence of feed additives on the reproductive traits of sows

Abstract

Currently, the main condition for the intensification of animal husbandry in Russia is the application of the concept of rational animal feeding. In accordance with this concept, animals should be provided with complete feed, and the organization of feeding should provide conditions for the effective use of feed and the regulation of microbiological digestive processes. The purpose of the work was to study the effectiveness of the effect of the phytobiotic “Intebio” and the probiotic “Profort” on the reproductive traits of sows. The scientific and economic experiment was conducted in 2020 on pregnant and suckling sows under the conditions of OOO “Agrofi rma Ariant” (Krasnogorsky settlement in the Emanzhelinsky area in the Chelyabinsk region). The results of research of the effect of phytobiotic “Intebio” and probiotic “Profort” on the reproductive traits of sows have been presented in the article. It has been found according to the results of the conducted research that feeding sows phytobiotic “Intebio” and probiotic “Profort” in addition to the main diet for 30 days before farrowing and for 30 days after the survey allows to increase the prolificacy of sows by 2,9 and 1,9 %, respectively, the weight of piglets at birth by 12,3 and 10,4 %, the weight at weaning by 11,9 and 11,2 %, the livability of piglets by 6,1 and 4,0 %. This made it possible to reduce expenditures feed per 1 kg of piglets’ live weight gain by 18,4 and 15,6 %. It has been found on the base of conducted research that the use of phytobiotic “Intebio” and probiotic “Profort” in the feeding of pregnant and suckling sows is economically justified.
