EFFICIENCY OF USING HIGH-PROTEIN SUNFLOWER MEAL INSTEAD OF SOYBEAN MEAL IN FEEDING OF GROWING PIGLETS

Abstract

The article shows the productivity of piglets when they were fed from day 42 to day 70 of this period with sunflower meal (SP-45) instead of soybean meal (SP-48). The manuscript highlights the effectiveness of replacing soybean meal with high-protein sunflower meal in the final period of rearing pigs. It was established that this change in the diet of piglets during their rearing period contributed to a 1.0% improvement in the survival of piglets during the experiment, at the same time it led to a 7.6% decrease in daily feed consumption, which caused a 9.7% deterioration in the intensity of animal growth and as a result of a 6.8% decrease in live weight of piglets at the end of rearing and a 2.3% decrease in feed conversion. The replacement of soybean meal with high-protein sunflower meal in the structure of the starter feed made it possible to reduce its cost by 4.7%, which made it possible to reduce the cost of 1 kg of growth by 2.4%, and the cost of growing 1 head before transfer to fattening by 8.2%. At the same time, in the group of pigs consuming sunflower meal due to a decrease in their productivity and a decrease in their final weight, as a result, the market value of one piglet before transferring them to fattening decreased by 5.9% and the income per 1 reared head decreased by 1.7%. Whereas in the group of piglets that used sunflower meal instead of soybean meal in the starter feed recipe, the profitability of raising piglets was 3.89% higher
