The use of premix in feeding of young pigs on fattening

Abstract

Increasing the production of pork meat requires careful work not only in terms of breeding, but also in the organization of complete feeding of animals, the correct selection of feed and feed additives containing the necessary nutrients. The purpose of the work was to analyze the use of premix in feeding young pigs on fattening. Two groups of fattening young pigs (Large White×Landrace) have been selected for the researches using the method of analogous groups, taking into account the breed, age, and live weight per 20 heads in each group with a live weight of 35 kg. Pigs of the control group have received the main economic diet, and animals of the experimental group have received an additional premix Khutorok at the rate of 10 g of premix per 1 kg of feed. The results have shown that the best age to reach 100 kg was in the experimental group of pigs – 215,8 days, which received premix with feed that characterizes their higher precocity by 36,3 days (P < 0,001) than in the control group of animals. The use of this premix had a positive impact on the livability of young animals, in the experimental group it was by 9,3 abs.% more than in the control group of animals. Thus, the best fattening traits have been possessed by young pigl of the experimental group have been received the premix Khutorok in their diet at the rate of 10 g of premix per 1 kg of feed. The obtained data indicate the feasibility of using the premix Khutorok in the feeding pigs for fattening.
