Feed taking fermented wheat bran and fermented beet pulp as raw materials for late-pregnancy sows

Abstract

The invention discloses feed taking fermented wheat bran and fermented beet pulp as raw materials for late-pregnancy sows. The feed is prepared from the following raw materials in parts by weight: 45to 50 parts of corn flour, 10 to 15 parts of wheat with husks, 15 to 20 parts of soybean meal, 10 to 20 parts of the fermented wheat bran and the fermented beet pulp, 3 to 4 parts of soybean oil, 0.8to 1.2 parts of calcium formate, 0.8 to 1.5 parts of calcium dihydrogen phosphate, 0.2 to 0.5 part of feed-grade sodium chloride and 0.5 part of an additive. By adopting the feed disclosed by the invention, the constipation problems of the late-pregnancy sows can be solved, and reproductive performance indexes including the farrowing rate, the weight of piglets, the living piglets and the like ofthe sows can be improved; meanwhile, a lot of low-price cellulose is applied, so that the cost of the feed can be reduced and the breeding income is improved.

Description

technical field [0001] The invention relates to the technical field of feed processing and production, in particular to a feed for late-pregnancy sows using fermented wheat bran and fermented sugar beet meal as raw materials. Background technique [0002] Constipation in sows in late pregnancy is a problem that plagues pig farms and formulators. The role of crude fiber in sow feed is particularly critical in this regard. Studies have shown that increasing the content of crude fiber and strengthening gastrointestinal motility can effectively prevent constipation. In addition, sows in late pregnancy have a better digestibility of crude fiber than growing pigs, and feeding low-fiber or fiber-free lactating sow feed in late pregnancy obviously does not meet the nutritional and physiological needs of sows in late pregnancy. Other studies have shown that adding crude fiber to sow diets during pregnancy to farrowing and weaning can significantly increase the number of piglets and t...
