Abstract

The improvement of production indicators (feed conversion ratio, average daily body weight gain, growth rate, etc.) in animal husbandry implies a high energy requirement. Such a need can only be met by including fats in the diet. Fat is the main and most efficient source of feed energy, but at the same time, one of the most expensive feed component. Using a fat emulsifier is an increase in the quality of the obtained product and a decrease in its cost. The addition of synthetic emulsifiers is a relatively new opportunity to increase fats’ active surface compared to other widely used feed additives. This reduces the cost for oil in the feed and also a chance to reduce feed total cost. By increasing fats’ active surface, emulsifiers expand the action of lipases and promote micelles formation. Higher the fat percentage in the diet, lower the percentage of its absorption. In high-energy diets without the use of complex emulsifiers, from 36% to 70% of the fat introduced into the feed is not absorbed and is excreted from the body. The beneficial effect of emulsifiers is that the digestibility of fat decreases, and it grows with an increase in the fat level in the diet. An assessment of the effect of the «Natufactant» feed additive on the growth rates of young pigs has been carried out. The maintenance and feeding of pigs were carried out in accordance with the technology adopted on the farm. The nutritional value of the main diet that is used on the farm, as well as after the inclusion of the feed additive «Natufactant», were determined. To conduct research according to the principle of analogs were taking into account the breed, live weight, and general physiological state, two groups of animals of a large white pig breed were created, 25 animals in each, with a live weight of 28 kg. The first group served as a control, and in addition to the main diet, the multicomponent emulsifier «Natufactant» was administered to the piglets of the research group at a dose of 250 g/t of feed, which was given together with the feed once per day. It was found that high average daily gains were obtained from animals to which «Natufactant» was added at the rate of 250 g per 1 ton of compound feed from the first day of the experiment and for 60 days in a row. As a result of the production check, it was found that the introduction of a feed additive into the diet of young pigs made it possible to increase the gross increase in animals’ live weight in comparison with the control, by 10.7 centners with the same level of feeding. New influence aspects of the fat emulsifier usage on the pigs’ physiological state and productivity were disclosed. It has been proven that the inclusion of the «Natufactant» feed additive into the animals’ diet stimulates the digestion processes and assimilation of basic nutrients, improves their physiological state, and increases the average daily weight gain of pigs by 15.3%. The solution to the problem of fats’ digestibility is the creation of new emulsifiers by searching for new molecules and developing effective complexes that have a synergistic effect when one component enhances the work of another. In order to significantly increase the pigs’ productivity and thereby increase the production of pork, it is necessary to ensure sufficient and adequate feeding of animals, taking into account the standards of lipid nutrition. It will also help to improve product quality and reduce production costs.
