The use of premixes with an increased level of group B vitamins when rearing and fattening of young pigs

Abstract

Vitamins take signifi cant place among the factors of complete feeding of pigs, their lack in the diet causes metabolic disorders, reduced productivity. The purpose of this work was to provide a practical justifi cation of diets for rearing and fattening young pigs based on concentrate mixtures enriched with mineral and vitamin premix with an increased content of group B vitamins. The selection of animals in groups has been carried out taking into account live weight, origin and health status, per 10 animals in each group. Animals in the control group have been fed a basic diet and premix P-554-89 in the amount of 1,0 % of the daily weight of the grain mixture, to piglets of the experimental group to the main diet with the mineral and vitamin premix of 1,0 % of the weight of the grain mixture have been added. The eff ect of the mineral-vitamin premix with increased level of group B vitamins on the digestibility of nutrients and energy metabolism has been studied. The eff ectiveness of rearing and fattening young pigs on diets with a high content of group B vitamins (B1 , B2 , B3 , B5 , B6 , B12) has been proven. Inclusion of a premix with increased content of group B vitamins compared to the recipe P-55-4-89 in the amount of 1,0 % of the weight of the grain mixture increases the productivity of young animals on fattening. At 8 months of age piglets reached a live weight of 109,1 kg, which was 8,8 kg or 8,77 % more than in control animals. The use of this premix in the amount of 1,0 % of the weight of the grain mixture reduces the prime-cost by 7,01 %, and the profi tability of rearing fattening young animals increases by 9,20 %.
