Abstract

The present invention discloses a preparation method of compound sow feed ina lactation period andbelongs to the technical field of animal feed. The compound sow is prepared from the following raw materials: palm meal, tofu residues, beer residues, cassava residues, rice bran, fish meal, molasses, and fructooligosaccharide. The preparation method comprises the following steps: palm meal treating, enzymatic digestion treating, rice bran treating, and mixing granulating. The sows fed by the provided compound feed are good in body conditions of the sows, less in fat losing during the lactation period, good in appetite, and enough in milk. The weaning piglets are large in body weight and robust. The compound sow feed is conductive to helping improve the economical efficiency of scaled pig farms.

Description

technical field [0001] The invention belongs to the technical field of animal feed, in particular to a method for preparing compound feed for lactating sows. Background technique [0002] At present, the annual litter number of sows in my country is 2.0, and the number of live piglets per sow is 15-20, but the number of live piglets weaned is only 14, and the number of commercial pigs that can be provided is about 12. Sows, especially primiparous sows, are prone to lactation insufficiency during lactation. The main reasons for lack of milk or no milk are: ①The sows are malnourished in the late pregnancy, the pigs are thin, and the mammary glands are not well developed; ②The mammary glands of primiparous sows are hypoplastic, hormones that promote lactation and neurological dysfunction, etc.; ③ The sow is too old, the appetite is not strong, and the digestion and absorption are not good; ④The sow is fed with too much energy feed during pregnancy, while other types of feed ar...
