Efficiency of use of oil production waste in pig feeding

Abstract

Purpose. To study the effectiveness of feeding adsorptive clay (perlite) as part of compound feed for young pigs on fattening. Methods. Deductions, scientific hypotheses and abstraction, zootechnical analysis, method of liquid chromatography, spectrophotometry, titrometry, variational statistics. Results. The high intensity of animal growth and metabolism in their bodies is impossible without supplying them with lipids in feed, therefore crude fat should be considered a mandatory component of diets for farm animals. Lipids in feed increase the amount of energy and this allows to reduce costs for grain components. Without lipids, the number of processes in the body would be impossible, including the normal functioning of the hormonal system, besides, the so-called essential fatty acids – linoleic, linolenic, arachidonic – affect the development and productivity of animals. First of all, vegetable oils and fish meal should be mentioned as fat-bearing feed components. The use of waste of vegetable oil production in compound feed for pigs is an additional source of fats. Adsorption clay is used for oil purification and refining in the production process and is disposed after technological cycle completion. The exhausted adsorption clay has a sufficiently high fat content in its composition. It has been established that the use of adsorption clay (perlite) in feeding young pigs reared for meat in the amount of 5% as part of compound feed has a positive productive effect, contributes to the increase of feed nutrition of compound feed, increase average daily gains of animals against control by 7.4%, live weight of 1 head at the end of the main period of the experiment by 5.14% and absolute gain by 7.23%. Conclusions. The use of adsorption clay (perlite) in compound feed for fattening young pigs contributes to increasing average daily gains and reducing costs of feed per unit of production.
