Growth rate of fattening pigs using the feed additive “Kormocid”

The use of acidifiers is aimed at stabilizing the gastrointestinal tract of animals, improving feed and water hygiene, and improving the palatability of feed. The purpose of our research was to investigate the growth intensity of fattening pigs when feeding the feed additive “Kormocid” on the growth intensity of fattening pigs and to establish the optimal dose of the additive. The scientific and economic experiment was conducted on 48 crossbred pigs (Large White x Landrace) 69 days old. The experimental pigs were divided into 4 groups (control and three experimental) of 12 heads each. The scientific and economic experiment lasted 100 days and consisted of 2 periods: equalization (15 days) and main (85 days). When forming groups, the following factors were taken into account: age, live weight of animals, origin, sex, productivity, growth rate of pigs, etc. The studied feed additive-acidifier “Kormocid” is produced by SE “Enzym”, Ukraine. It is a high-quality acidifier based on 5 organic acids (formic, propionic, lactic, citric, ascorbic). The amount of organic acids in the finished product is not less than 50 %. Feeding the compound feed “Growera” in combination with the drug “Kronocid” at a dose of 1.0 kg/1 ton of compound feed contributes to an increase in live weight in pigs of the fourth experimental group to – 68.1 kg compared to 65.1 kg of animals in the control group. The introduction of the feed additive “Kormocid” to pigs of the second, third and fourth experimental groups allows to increase the average daily gains by 75 g, 56 g and 113 g P < 0.05) against control analogues. The use of the drug “Kormocid” in the diet of pigs during the feeding period of the compound feed “Finisher” contributes to an increase in the average daily gains by 13.2 % (P < 0.01) and the live weight of fattening pigs by 8.2 % (4th experimental group) compared to animals of the 1st control group. The use of the drug “Kormocid” during the fattening period of pigs at a dose of 1.0 kg/1 ton of compound feed allows to reduce feed costs per unit of gain and increase the payment for feed by gain.
