Growth rate of fattening pigs with the feeding of the complex biological additive “MikoStop”

Pig farming is a strategic industry that ensures the country's food security. One of the main conditions for the effective production of pig products is biologically complete animal feeding, which is confirmed by numerous scientific studies and practical experience. Today, various feed additives are being searched and studied that increase the efficiency of feed use, reduce their cost, improve product quality and reduce the effect of toxic compounds in feed. The purpose of our experimental studies was to investigate the effect of the complex biological sorbent “MikoStop” on the growth rate of crossbred piglets during fattening and to establish the optimal dose of the additive. The article presents the results of studies on the influence of feeding the complex biological sorbent “MikoStop” on the growth rate of pigs during fattening. For the scientific experiment, 48 heads of crossbred pigs were selected, from which 4 experimental groups were formed. The control group of pigs during the equalization and main periods consumed the main ration – complete compound feed TM “Tsekhavit”. The experimental groups were fed different doses of the complex biological sorbent “MikoStop” in addition to the main ration. The duration of the equalization and main periods was 15 and 85 days, respectively. The studied supplement “MikoStop” is produced by SE “Enzym”, Ukraine. The drug “MikoStop” is a complex biological sorbent of feed toxins with probiotic, antiviral, hepatoprotective and immunoprotective properties. Composition: activated special yeast cell walls, mannan-oligosaccharides, mineral carrier and probiotic culture. It was established that feeding the complex biological sorbent “MikoStop” in combination with the compound feed “Grower” contributes to an increase in the growth rate of experimental pigs, however, no significant difference with the analogues of the control group was observed. In pigs of the 4th experimental group, to which the complex preparation “MikoStop” was added at a dose of 0.75 kg/1 t of compound feed, the live weight at the end of the period of feeding “Grower” (114 days) was 68.3 kg, which is 2.3 % more compared to the animals of the control group. The use of the preparation “MikoStop” during the period of feeding pigs on fattening compound feed “Finisher” causes an increase in the live weight of animals. In particular, the third experimental group, which consumed the drug “MikoStop” at a dose of 0.5 kg/1 ton of compound feed at the end of the fattening period (165 days), had the highest live weight – 119.6 kg among the experimental groups compared to the control analogues, while the live weight of animals in the 2nd experimental group was at the level of – 115.8 kg and the 4th experimental group – 114.7 kg. It was recorded that the use of the drug “MikoStop” at a dose of 0.5 kg/1 ton of compound feed “Finisher” provides at the end of the fattening period (165 days) average daily gains at the level of 1088 g, which is 189.5 g more than the analogues of the control group.
