Lactating feed for improving reproductive performance of sows by using dry blasting soybeans and preparation method for lactating feed

Abstract

The invention discloses a lactating feed for improving the reproductive performance of sows by using dry blasting soybeans and a preparation method for the lactating feed. The feed comprises 30%-55% of corn, 4%-10% of alfalfa grass, 4%-10% of soybean hulls, 15%-25% of soybean meal, 4%-6% of fermented soybean meal, 2%-4% of super fish meal, 0-3% of glucose, 0%-2% of soybean oil, 5%-10% of dry blasting soybeans, 0.3%-0.4% of acidifier, 4% of 4% premixed feed, wherein the dry blasting soybeans are prepared by processing raw soybeans with high temperature through a high-temperature pre-curing processing technique; the dry blasting soybeans can effectively reduce the anti-nutritional factors, antigen protein and unhealthy oligosaccharides in the soybeans; the protein of the dry blasting soybeans wraps fat, so that oil oxidation is reduced, and the utilization rate of the protein and oil is greatly improved; and the dry blasting soybeans have a strong smell. The digestion and absorption rateof the protein and fat of the lactating feed using dry blasting soybeans is effectively improved, and the reproductive performance of the sows during the lactating period is improved.

Description

technical field [0001] The invention belongs to the technical field of feed and relates to a compound feed for lactating sows and a preparation method thereof, in particular to a lactation feed which uses dry-exploded soybeans to improve the reproductive performance of sows and a preparation method thereof. Background technique [0002] Soybean is the only major food crop in the world that is confirmed to be native to China. It has been cultivated in my country and used as food and medicine for 5,000 years. In addition, it is distributed in North China, Shaanxi, Sichuan and the lower reaches of the Yangtze River, and is mostly cultivated in the Yangtze River Basin and Southwest. Soybean has the most abundant nutrient elements in legumes, and is easy to digest and absorb. The protein content of soybean is about 38% to 42%. It is the most abundant and cheapest source of protein intake for humans and animals. [0003] With the rapid development of the livestock and poultry bree...

Problems solved by technology

At present, many sow feeds add puffed soybeans, but puffed soybeans have certain defects during use. Most of the fat contained in puffed soybeans is attached to the surface, and the storage time and storage temperature must be strictly controlled, otherwise the fat is easy to oxidize Rancidity affects the effect of use

[0005] As the proportion of high-yield sows fed in large-scale pig farms is increasing, high-standard nutrition and feeding management must be matched to achieve high-yield goals; Improve feed energy concentration, but the disadvantage of adding oil or puffing is that oil and puffed soybeans are easily oxidized during production, processing, and storage, which greatly affects the feed intake of lactating sows, thereby affecting the reproductive performance of lactating sows; Therefore, it is necessary to explore a new soybean raw material processing method to realize the supply of new varieties of energy raw materials
