Abstract

One of the main problems in the feeding of farm animals is the low degree of digestion and assimilation of nutrients in the feed used in animal production. In the bodies of animals such as pigs and poultry enzymes and microflora which are necessary for breaking down cellulose and other polysaccharides of vegetable raw materials are absent, therefore they not only fail to be digested in the gastrointestinal tract, but also obstruct access of other digestive enzymes to the other feed components, in particular intracellular proteins. The only way to solve this problem is deliberate introduction of enzymes into food. Depending on the type and composition of the feed, amylolytic, proteolytic, cellulolytic enzyme preparations are used. The purpose of this work is to assess the effect of the enzyme preparation "Celloviridin Dx20" as a fodder component on the growth and biochemical parameters of young pigs. For this purpose, a scientific and economic experiment on feeding young pigs was conducted at the agro-industrial farm«Niva» (Novonikolaevka village, Dnipropetrovsk region), in which the enzyme preparation «Celloviridin Dx20», which promotes the breakdown of plant cell polysaccharides (cellulose, xylans) was introduced to a standard feed mixture used in swine husbandry. The composition of the ration consisted of 60% barley, 20% wheat and 20% of the protein-vitamin-mineral complex «ShenPigStart». The results of the experiment showed that the introduction into the feed mixture of the enzyme preparation at 100 g per ton helps to increase the body weight of pigs by 11.6% compared to the control, can increase the digestion rate of fibre (13.8%), protein and fat. These results can be explained by the mechanism of action of the enzyme complex, which consists in the hydrolysis of polysaccharides of plant cell walls in the feed in the digestive tract of pigs, the formation of digestable polysaccharides and the release of additional quantities of intracellular proteins. The result of these phenomena is also a positive trend in feed nitrogen assimilation in animals of the experimental group: a 19% decrease in the amount of physiological secretions and a 12.5% increase in nitrogen use. At the same time hematology (hemoglobin, erythrocytes, leukocytes), calcium and phosphorus metabolism remained unchanged. This shows that the preparation used does not accumulate in the body and gradually loses enzymatic activity, and under the influence of the pigs’ stomach proteases it is broken down into separate amino acids which are absorbed by the animals. The resulting stimulatory effect of using "Celloviridin Dх20" has not only physiological but also economic importance, as it helps reduce the time for the pigs to reach slaughter weight (close to 100 kg) by 11 days, and consequently, reduces feed intake and its costs in rearing pigs on farms. Therefore, it is advisable to use "Celloviridin Dх20" in swine husbandry.
