Productivity of pigs when feeding celluloseamylolytic additive

Abstract

The use of different feed processing methods using exogenous feed additives to improve the digestibility of plant feed ingredients in pig feeding has been studied for decades. In the research laboratory of the Institute of Forage and Agriculture of Podillya NAAS, compositions of enzymes with cellulase and amylase activity were studied. They are able to effectively break down non-starch polysaccharides in cereals, increase digestibility and absorption of feed nutrients. The purpose of this work was to study the zootechnical efficiency of the use of biologically active in the composition of feed pigs for fattening. In the presented material, the influence of feeding cellulose amylolytic enzyme additive on the productive qualities of pigs for fattening is highlighted. The cellulose amylolytic additive contained α-amylase with an activity of 9342 IU/h and cellulase with an activity of 540 IU/h. Studies in pigs were performed in two stages: the equalization period (15 days) and the main (71 days). For feeding pigs, a feed mixture was used, consisting of feed grown directly on the farm – barley, wheat, soybeans. The diet of the control group consisted of 63 % barley grain, 27.5 % wheat grain, 9 % soybean meal 0.5 % mineral supplement. Pigs of the experimental group were fed cellulose amylolytic feed additive at the rate of 5 g of cellulase and 1 g of amylase per 1 kg of feed. Feeding supplements determines the intensity of the process of digestion of proteins, fats and carbohydrates. Cellulose-amylolytic additive affects the absorption of carbohydrates in the diet, providing an increase in the digestibility of the control and experimental groups, respectively, neutral-detergent fiber (38.2 and 46.7 %), acid-detergent fiber (18.7 and 36.5 %), the amount easily hydrolyzed carbohydrates (85.4 and 90.2 %), hemicellulose (65.7 and 61.5 %), cellulose (13.2 and 21.4 %). The decision on the feasibility of including cellulose-amylolytic additive in the diet can be confirmed on the basis of its use during the scientific and economic experiment. In the control group, the average daily increase in live weight was 725.07 g, and in the experimental group by 19.7 % more at the level of 902.53 g. It was also noted a positive effect on the formation of body biomass, development of individual organs and their systems.

“…A total of 2,991 protein-coding sequences, 65 tRNAs and 16 rRNAs were annotated (Table 1). Genomic sequence analysis showed that SK156 possessed genes encoding for α-amylase enzyme, which hydrolyzes α-bonds of polysaccharides and generate malto-oligosaccharides in animal feed [4][5][6].
