Problems solved by technology

If the lactating sow lacks the first limiting amino acid lysine, the feed intake of the sow will decrease, and the lactation will decrease, which will cause the suckling piglets to gain weight slowly, and malnutrition will easily cause diarrhea and other diseases, resulting in pig stock Small quantity and slow production speed

Abstract

The invention discloses a feed additive for increasing the food intake of sows in lactation, which consists of the following ingredients by weight portions: 35 to 46 portions of L-lysine; 22 to 28 portions of L-valine; 9 to 16 portions of L-threonine; 1 to 8 portions of DL-methionine; 5 to 8 portions of L-tryptophan; 3 to 6 portions of vitamin C; 1 to 3 portions of glutamine; and 2 to 5 portions of plantain. The feed additive has the following advantages: a nutrition potentiator is added in feed to product the feed capable of increasing the food intake of sows in lactation and the weaning weight of piglets; when the feed is fed to the sows in lactation, the immunity of the sows can be notably enhanced, the milk yield can be notably increased, and the weaning weight of the piglets can be notably increased.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving feed intake of sows during lactation. Background technique [0002] With the improvement of people's living standards, the demand for livestock products continues to increase, and the breeding industry is developing in the direction of scale and standardization. Through genetic selection, the reproductive performance of modern lactating sows has been continuously improved, the average litter size has increased from 8-10 to 12-14, the weaning litter weight has increased from 45kg at 28d to 70kg at 21d, and the lactation volume has increased from 4-10 Increased from 5kg / d to 10-12kg / d, litter size and lactation have been significantly increased, while feed intake has decreased, thus increasing a huge production burden on lactating sows, according to sows Due to production needs, pig nutritionists at home and abroad are trying to find nutritional strategies that can ...
