A method for increasing the productivity of meat gobies thanks to the use of cavitated sunflower oil sludge in the diet

Abstract

Abstract The paper presents the results of studies on the use of cavitation-treated sunflower oil-sludge in the diets of young cattle, when grown for meat. The analysis of the data showed that the introduction of native and cavitated oil sludge into the diet of bulls affects the indicators of the intensity of their growth with a pronounced effect for cavitated oil sludge. So, bulls of the II experimental group in live weight exceeded their herdmates from the control and I experimental groups at the age of 18 months - by 4.6% (P≤0.05) and by 2.0%. In terms of the average daily gain, the animals of the II experimental groups, for the entire period of the experiment, exceeded the control and I experimental groups by 5.1-14.2%, respectively. The use of oil sludge, subjected to cavitation treatment, in feeding young cattle is economically profitable. Additional profit is 1105.2 rubles. per head, and the level of profitability of beef production at the same time increases by 2.75%. This testifies to the economic feasibility of the practical application of cavitated sunflower oil-sludge.
