Sorghum medium pig feed and preparation method thereof

Abstract

The invention discloses sorghum medium pig feed and a preparation method thereof. The sorghum medium pig feed comprises corn, 46% bean pulp, corn DDGS, rice bran, sorghum, a premixing compound and a liquid enzymic preparation. The sorghum medium pig feed and the preparation method thereof have the advantages that the American sorghum low in tannin content is used for replacing the corn at a high price, an appropriate quantity of the liquid enzymic preparation containing phytase is added, in this way, the digestion and absorption capacity of pigs for all nutrients is remarkably improved, the digestive utilization ratio of the sorghum is improved, and therefore the consumption of the corn and the bean pulp in the formula is reduced; by adding some traditional Chinese additives, the sorghum medium pig feed has the auxiliary functions of harmonizing the stomach for descending adverse qi, warming the spleen and reinforcing the kidneys, in this way, the appetite and the absorbing performance of the pigs are improved, and the material-pork conversion ratio is higher; the feed utilization efficiency is improved, the pigs are promoted to grow, the feed cost is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention relates to a feed, in particular to a sorghum-type pig feed and a preparation method thereof. Background technique [0002] Monitoring data show that in the past three months, the national average price of corn has risen by more than 10%. Since June, the drought caused by the continuous high temperature and lack of rain in many northern provinces has caused the price of corn to continue to rise and increase the cost of feed. According to data from the website of the Ministry of Agriculture, from June to July, the precipitation in most of North China, most of Huanghuai, Jianghuai, Jianghan, central and southern Shaanxi, and southeastern Gansu is generally 20-50% lower, and the temperature is relatively high. Fast development. According to the Ministry of Agriculture's August 4 agricultural situation dispatch, the country's drought-affected area is more than 64.2 million mu, of which 17 million mu is severely drought-affected. The droug...

Problems solved by technology

However, the protein content of sorghum is low, and the content of essential amino acids cannot meet the nutritional needs of livestock and poultry. In particular, the content of lysine, sulfur-containing amino acids and tryptophan is less than half of the pig's requirement. Except for iron, all minerals Neither can meet the nutritional needs of pigs

However, the sorghum currently planted still contains a large amount of anti-nutritional factor complex-tannin, which can make the protein difficult to be digested and absorbed, and inhibit the growth of poultry animals. The proportion of sorghum in the feed depends on the content of tannin. The content of tannic acid in livestock and poultry diets below 0.2% will not affect the feeding effect
