Abstract

The invention belongs to the technical field of sow raising, and specifically relates to feed used for a sow at a perinatal period. The feed is prepared from the following components by mass percentage: 30%-64% of corns, 4%-10% of wheat bran, 10%-15% of soybean meal, 3%-10% of fermentation-enzymolysis soybean meal, 8%-18% of wheat, 3%-8% of skin of bean curd, 2%-8% of fish meal, 1%-3% of fatty powder, 1%-3% o soybean oil, 3%-5.5% of minerals, 0.3%-1% of amino acid, 0.2%-1% of vitamin, 0.02%-0.2% of complex enzyme preparation, 0.1%-1% of a microorganism probiotics group, and 0.1%-1% of citric acid. The feed provided by the scheme can be used for improving immunity of the sow at the perinatal period, lowering the generation possibility of endotoxin in a sow body as well as harms, relieving stress in sow farrowing, changing materials and the like, promoting the post-partum recuperation, the normal ingestion and milk production of the sow, promoting intestinal health, ensuring the health of the sow and piglets, and improving productivity.

technical field [0001] The invention belongs to the technical field of sow feeding, and in particular relates to a feed for sows in the perinatal period and a preparation method of the feed. Background technique [0002] The sow peripartum period refers to the period from 7 days before delivery to 7 days after delivery. At this time, the sows have breast edema, low appetite, loss of body fluids, and huge physical exertion, while milk production gradually increases and enters the stage of negative nutritional balance. Sows not eating after delivery is a common symptom in pig farms. Unreasonable fetal tapping in late pregnancy, premature fetal tapping, excessive feed nutrition level or high feed intake of sows will cause sows to overeat and digest Disturbance, which leads to the prolonged labor process of sows, poor resistance of sows, prone to metritis and mastitis, manifested as weak production of sows, postpartum anorexia, poor milk quality, diarrhea of ​​piglets, poor body...
