Special compound feed for pregnant pigs in later stage

Abstract

The invention discloses a special compound feed for pregnant pigs in the later stage. The special compound feed has the functions of improving nutrition, increasing resistance, maintaining normal body storage, promoting fetal development and preventing pig constipation, and thus the production performance of the pigs is improved. The feed comprises following components in parts by weight: 400 to 600 parts of corn, 150 to 300 parts of wheat bran, 20 to 60 parts of puffing soybean flour, 180 to 220 parts of soybean meal, 12 to 15 parts of calcium hydrogen phosphate, 10 to 20 parts of stone powder, 1 to 3 parts of lysine, 1 to 3 parts of methionine, 1 to 4 parts of threonine, 2 to 5 parts of compound trace elements and 2 to 5 parts of compound vitamins.

Description

technical field [0001] The invention relates to a special compound feed for late pregnant sows. Background technique [0002] At present, the breeding industry is developing rapidly, but limited by various conditions, professional farmers have a vague understanding of the feeding of pregnant sows, especially in the late pregnancy, there are a series of problems in pregnant sows, which seriously affect the production performance of sows. Most professional farmers are unaware of using a special compound feed for late-pregnancy sows, some farmers continue to use compound feed for pre-pregnancy feeding, and quite a few realize that the nutritional level in the early-pregnancy period is too low to meet the requirements of later-stage feeding Requirements, use lactating sow feed instead. Both of them, to a large extent, do not conform to the physiological characteristics of late pregnancy, and both have great hidden dangers. Therefore, there is an urgent need for a special compo...

Problems solved by technology

[0003] In the previous technology, feeds for lactating sows were used during the gestation period. The feed for lactating sows focused on the lactation performance of sows, which may cause premature development of mammary glands in late pregnancy sows, and the lactation function cannot be started in time. In addition, If the content of crude fiber in the feed of lactating sows is too low, the pregnant sows will experience constipation in the later stage, which will affect the normal physiological function
