Abstract

The modern pig breeding is focused on the constant improvement o f pig housing conditions, ensuring high quality and safety o f products, using effective feeding and breeding technologies, as well as the balanced consideration o f ecological and economic aspects. New methods o f rearing andfattening pigs affect not only the quantity, but also the quality o f the slaughter raw materials obtained. Objective. To study the effect o f the complex supplement "Hepasorbex" on the amino acid composition o f the studied groups o f pigs in the conditions o f a commercial enterprise in accordance with the industrial technology. Methods. On the basis o f the above, fo r the assessment o f slaughter qualities, young animals were selected fo r slaughter from groups offattening young animals when piglets reached a live weight o f 100 and 120 kg in the amount o f 10 heads o f each weight condition under the conditions o f the limited liability company "Tavriiski Swyni". Next, it has been studied the effect o f the complex supplement "Hepasorbex" on the amino acid composition o f the muscle tissue ofpigs o f experimental groups with a pre-slaughter live weight o f 100 and 120 kg in the amount o f 5 samples o f each group. Results. It was revealed the deep changes in the animal body: in particular, in the amino acid composition o f muscle tissue (replaceable, essential amino acids and their ratio) by detailed researches. Thus, 100 g o f muscle tissue protein obtainedfrom the carcasses o f pigs o f the III research group: fo r pre-slaughter live weight o f 100 kg, contains 9.11 g o f essential amino acids and 11.43 g o f replaceable amino acids, the amino acid index is 79.7 %; fo r pre-slaughter live weight o f 120 kg - essential amino acids - 10.41 g, replaceable - 13.83 g, amino acid index - 75.27 %. The animals o f the III research group are characterized by the maximum value o f the protein-quality index at slaughter both at 100 kg and at 120 kg - 12.22 and 7.39, respectively, that is, "Hepasorbex" contributed to the biosynthesis o f meat o f better quality. Conclusions. According to the general zootechnical requirements, the protein-quality index (oxyproline, tryptophan and their ratio) o f the III research group corresponds to high-quality pork (7.39 - 12.22), while the II research group (7.02 - 11.58) and the I control group (6.7 - 12.21) meet the requirements ofpork o f normal quality.
