Lactating sow feed for improving production performance of sows and piglets

Abstract

The invention provides a lactating sow feed for improving the production performance of sows and piglets. The technical characteristics include: mixing a variety of monomer vitamins, a carrier, traceelements with various amino acids, an enzyme preparation, calcium dihydrogen phosphate and the like into a premix; crushing first-class corn, soybean meal and the like with a wide pulverizer; mixing the crushed first-class corn, soybean meal with the premix, puffed soybean flour, wheat bran, oil and the like; employing double-layer conditioning to ensure soil certain ripening degree and make particles; utilizing a cooler for cooling, and performing dehydration to obtain a finished product. The feed provided by the invention can effectively avoid the problems of constipation, lacrimal spots andsurface crusting in sows, shorten the sow parturition, reduce the occurrence of postpartum triad syndromes (mastitis, hysteritis, and agalactosis), and improve the production performance of lactatingsows. The feed provides sufficient nutrition to sows during lactation, improves the average weaning weight of piglets, the weaning litter weight of piglets, the average daily gain of piglets and theaverage daily lactation yield of sows, shortens the weaning-oestrus interval of lactating sows, can achieve rapid estrus mating in 3-5 days and large litter size.

Description

technical field [0001] The invention relates to a feed for lactating sows to improve the production performance of mother and child. Background technique [0002] The quality of feed for lactating sows not only directly affects the milk yield of sows, the survival rate of weaned piglets and the weaning weight of piglets, but also affects the normal estrus and mating of sows after weaning. The survival rate of piglets and the growth during lactation affect the economic efficiency of the entire pig farm. At present, the common feed for lactating sows in the market is likely to cause problems such as poor lactation, constipation, tear spots, scabs on the body surface, postpartum fat loss, and postpartum triads (mastitis, metritis, agalactia) disease), which has a huge impact on the overall productivity of the pig farm. Contents of the invention [0003] The object of the present invention is to provide a feed for improving the production performance of lactating sows in vie...
