Lactation compound feed for sows and preparation method thereof

Abstract

The invention discloses lactation compound feed for sows and a preparation method thereof. The lactation compound feed for sows is made from wheat, corn in northeast China, 46% soybean meal, soybean hull, calcium hydrophosphate, rice bran oil, liquid phytase, liquid compound enzyme, limestone flour, salt, 65% lysine, threonine, 60% choline chloride, antioxidant, plasma protein, potassium chloride, magnesium sulfate, vitamin prefix, and trace mineral premix. The preparation method include: weighing all materials by percent weight, and adding the materials into a crusher for crushing under the crushed size of 25-40 mesh; and adding the crushed materials into a pelletizer to make pellets at 85 DEG C with gelatinization degree reaching more than 90%. The lactation compound feed for sows has the advantages that the lactation compound feed for sows meets requirements of nursing sows for nutrition and is high in palatability, immunity, milk yield and milk quality are increased for the sows, and productivity of piglets is further improved.

Description

technical field [0001] The invention relates to a compound feed for feeding lactating sows, in particular to a compound feed for lactating sows and a preparation method thereof. Background technique [0002] Sow feeding is one of the important links in pig production. In production practice, how to improve the production performance of sows is the focus of pig production. Large sow litter size, high piglet survival rate, and prolonged utilization of sows have always been the goals pursued by pig farmers. Lactating sows not only need to maintain their own life needs, but also need to restore their prenatal body condition after giving birth, and also need to lactate to supply piglets. The resistance of sows is lowered, and they are prone to diseases, which not only affect their own milk production and production performance, but also It also reduces the quality of milk and affects the growth rate of piglets, piglet vitality, weaning weight, loosening rate and survival rate of...

AI Technical Summary

Problems solved by technology

Compared with corn, the nutritional value of wheat is higher in crude protein, calcium, and phosphorus, but its metabolizable energy and feed utilization rate are lower, and wheat contains non-starch polysaccharides (NSP) such as arabinoxylan and β-glucan. And anti-nutritional factors such as crude fiber, trypsin inhibitor, plant lectin and some special structural proteins that are difficult to be digested, if directly fed in large quantities, it will not only wrap nutrients, hinder the interaction between nutrients and digestive enzymes, but also cause Causes functional damage to livestock and poultry, and ultimately manifests as reduced utilization of nutrients and inhibition of animal growth
