Abstract
The authors carried out researches to study the effect of complex feed hydrolysate on the zootechnical parameters of piglets of the rearing group. As a result of the experiment, it was found that the productivity of piglets in the experimental group was higher than in the control group by 1.07 kg (3.61%), 1.45 kg (4.90%) and 2.10 kg (7.09%). When analyzing the weight gain of piglets, an increase in this parameter was also found in the experimental groups. Thus, in the 1st experimental group, the weight gain of piglets during the study period was 4.42% higher than in the control group, 6.72% higher in the 2nd experimental group and 7.87% higher in the 3rd group. The results of calculating feed costs per 1 kg of animal weight gain showed that in the 1st, 2nd and 3rd experimental groups, the conversion of compound feed was 1.88 kg, 1.82 kg and 1.81 kg, which is respectively lower than in the control group by 4.09%, 6.65% and 7.16%. The results of the general and biochemical analysis of piglets’ blood, reflecting metabolic processes and the state of internal organs, showed the absence of a negative effect of the feed additive on the animals’ body, the studied parameters were within the limits of intraspecific norms. The results of physiological experiments showed that the use of feed additives in the diet of pigs contributed to a positive effect on the level of digestibility of individual nutrients in the diet.
