EFFECTIVENESS OF VARIOUS METHODS OF PREVENTION OF MYCOTOXICOSIS IN GROWING PIGS
Abstract
The paper presents the results of research on the effectiveness of various methods of preventing mycotoxicosis in young pigs, namely the use of sorbents and a complex drug that is a mold inhibitor and antifungal agent and is added to grain when it is stored. According to the research methodology, at their first stage, when harvesting corn grain, part of it was put into storage with an additional (1 kg per ton) introduction of the drug Micofang. After 3 months of storage, average samples of fungicide-treated and untreated corn grain were taken for research on the presence of mycotoxins. According to the results of laboratory studies, in the grain of corn that was not treated with a fungicide, an increased content of T-2 toxin and deoxynivalenol was observed by 3.5 and 3.7 times, respectively, compared to the standards. At the second stage of research, a feeding scheme and compound feed recipes were developed for two groups of young pigs. Grains of own production were used for the production of compound feed, including and corn stored after pretreatment with a protective drug (experimental group) and without it. For the prevention of mycotoxicosis in animals of the control group, a sorbent was included in the compound feed. The results of the experiment showed that the piglets of the control group during the entire growing period were inferior to their counterparts from the experimental group in terms of growth intensity. But the difference at all stages of the experiment was insignificant and, accordingly, improbable. At the end of the growing period, the difference in the average live weight of one head was 2.1 kg. Over the entire period of the experiment, the average daily growth of piglets in the control and experimental groups was 721±11.9 and 737±12.4 g, and feed conversion was 2.98 and 2.88 combined feed per 1 kg of growth, respectively. The economic evaluation of the results of the experiment showed that the use of the fungicide Mycofang for preventive treatment of corn grain is more appropriate, compared to the use of a sorbent when feeding pigs with fodder affected by mycotoxins.
