Concentrated feed for lactating sows

Abstract

The invention discloses concentrated feed for lactating sows. The concentrated feed for lactating sows is made from the following raw materials proportioned in parts by weight: 25 parts of soybean oil, 414.71 parts of soybean meal, 300 parts of fermented soybean meal, 61 parts of stone powder, 42.91 parts of calcium hydrogen phosphate, 18.88 parts of sodium chloride, 10 parts of sodium sulfate, 5parts of magnesium sulfate, 4 parts of trace element premixed feed, 80 parts of fish meal, 30 parts of lysine, 1 gram of micro-ecological preparation, 1 part of enzyme preparation, 0.3 part of of freshness-retaining agent, 2.2 parts of vitamin premixed feed and 4 parts of choline chloride. The concentrated feed for lactating sows can greatly improve milk yield and milk quality by nutritionally regulating the endocrine system of sows to provide sufficient milk for piglets, so that the piglets grow fast, laying an important physical foundation for the growth of the piglets.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a concentrated feed for lactating sows. Background technique [0002] The purpose of raising sows is to require sows to provide as many high-quality weaned piglets as possible, so as to provide the largest amount of commercial meat pigs. Lactating sows are the key link in large-scale or professional household pig production, which is related to the cultivation of piglets and at the same time It also affects the production level of the next generation of sows in the reproductive cycle. [0003] At present, with the rapid development of the breeding industry in the direction of scale and standardization, the feeding of lactating sows has always been a bottleneck in my country's pig industry. The particularity of nursing sows also determines that lactating sows cannot rely on simple diets and nutrition like growing and finishing pigs. The development of mammary glands, the secretion of prolacti...
