Influence of Primix-Alfasorb on digestibility of nutrients in growing pigs

Abstract

The research was conducted using growing pigs which were divided into four experimental groups. The goal of the digestibility trial was to study the nutritive value of the foods of local origin and the digestibility of nutrients under the influence of the adsorbent Primix-Alfasorb at various levels: 0.2, 0.4 and 0.6 kg/t respectively in the experimental groups EG1, EG2 and EG3. The obtained results showed that the Primix-Alfasorb had a positive impact on the nutrient digestibility in growing pigs in all the experimental groups compared with the control group. No significant differences in digestibility coefficients of dry and organic matter were observed. The data on digestibility of nutrients were higher in all the diets for the experimental groups, but the significant effect (P <0.05) was observed in crude fat in EG1. The digestibility coefficient of NFE (nitrogen-free extract) in the experimental groups EG2 and EG3 was higher respectively by 2.04 and 2.06 % than the digestibility coefficient in the control group (P<0.01 and P<0.05). Only the digestibility of cellulose was lower in the experimental groups compared with the control group, because pigs, especially young animals, digest cellulose worse. There was no significant influence on the animal’s live weight.
