Compound premixed fermented feed for pregnant sows

Abstract

The invention relates to a compound premix fermented feed for pregnant sows. The feed is prepared from the following raw materials in parts by weight: 25 to 30 parts of fermented rice bran; 17 to 19 parts of medical stone, 22 to 25 parts of stone powder; 1.5 to 3.0 parts of choline chloride; 15 to 18 parts of calcium hydrophosphate; 6.5 to 9.0 parts of sodium chloride; 0.5-2 parts of lysine, 0.2 to 0.4 part of calcium iodate; 0.05 to 0.2 part of sodium selenite, 0 to 0.5 part of cobalt chloride, 0.5 to 2 parts of ferrous sulfate, 0 to 0.5 part of copper sulfate pentahydrate, 0 to 0.5 part of zinc oxide, 0 to 0.4 part of manganese sulfate, 0 to 0.2 part of vitamin E, 0.25 to 0.5 part of piglet compound multi-vitamin, 0.1 to 0.3 part of phytase and 0.3 to 0.6 part of a flavoring agent. The feed has the advantages that the activity and feed intake of sows are increased compared with the prior art, the survival rate and average weight of piglets are increased, the diarrhea rate of the piglets is reduced, and the reproductive performance of the sows is effectively improved.

Description

technical field [0001] The invention relates to the field of sow feed, in particular to a compound premixed fermented feed for pregnant sows. Background technique [0002] For pig farms, the farrowing rate, piglet survival rate and slaughter rate are important lifelines for their development, which mostly depend on the nutritional intake and health status of sows during pregnancy. It is a very important production link in the process. However, in the existing pig breeding in my country, in order to increase the number of breeding and reduce feed input, farmers often use limit stalls for sow breeding. The sows have a small space for movement, less exercise, and the growing fetus oppresses the intestinal tract, which leads to slow gastrointestinal motility. , coupled with limited feeding during pregnancy, insufficient nutritional intake and other reasons, the immunity of sows is reduced, and their health is facing serious threats. In the end, many problems occurred, such as l...

Problems solved by technology

[0004] The invention patent with the publication number CN108208416A discloses the use of fermentation and full-matured technology to support the nutritional formula of pregnant sows. However, this patent requires high production equipment and technical capabilities. Many feed factories do not have the corresponding capabilities. In addition, many raw material fermentation processes The intermediate products are complex and diverse, it is difficult to control the degree of fermentation, and it is difficult to promote it on a large scale
