Preparation method of distiller's grains feed for breeding Qianbei black pigs

Abstract

A preparation method of the distiller's grains feed for breeding Qianbei black pigs comprises the following steps: heating and drying fresh corn distiller's grains until the water content is 8-10%; uniformly mixing the dried fresh corn distiller's grains, corn flour, sorghum flour, soybean flour and bran, performing standing for 12-14 hours, adding 2-3 kilograms of fish meal and 1-3 kilograms of brown sugar, performing heating to 35-40 DEG C, and performing uniform mixing by stirring; performing anaerobic fermentation on the uniformly mixed raw materials, wherein the anaerobic fermentation temperature is 20-23 DEG C, and the anaerobic fermentation time is 48-72 hours; and taking out the raw materials subjected to anaerobic fermentation, uniformly mixing 1-2 kilograms of table salt, 0.3-0.5kilogram of vitamin B and 0.3-0.5 kilogram of vitamin C, and performing uniform mixing by stirring at 25-30 DEG C. According to the preparation method of the distiller's grains feed for breeding Qianbei black pigs, body immunity of the Qianbei black pigs can be effectively improved, the weight of the Qianbei black pigs can be improved, and positive effects of promoting fattening of the Qianbei black pigs and shortening the slaughtering period are achieved.

Description

technical field [0001] The invention relates to the technical field of pig feed processing and production, in particular to a method for preparing distiller's grains feed for black pig breeding in northern Guizhou. Background technique [0002] In recent years, with the improvement of people's living standards, the requirements for the quality of meat products are getting higher and higher, especially for the pig breeding industry. Qianbei black pig is welcomed by people because of its high slaughter rate, good carcass quality, excellent meat quality and good taste. Qianbei black pig is a specialty product of Zunyi City, Guizhou Province, and is a national agricultural product geographical indication. Its body is black in coat, its head is moderate in size, its ears are large and drooping, its mouth is long and straight, its forehead wrinkles are mostly diamond-shaped, its neck is moderate in length, and its back and waist are slightly concave. , longer and narrower, fuller...

Problems solved by technology

However, without grasping the characteristics of the distiller's grains themselves, they simply mixed them and did not provide reliable conditions during the production, resulting in varying degrees of fermentation of distiller's grains and food materials, and often rotten distiller's grains and food materials. The nutrient composition of the Qianbei black pig feed is lost, making it difficult to meet the growth nutrition intake requirements of Qianbei black pigs

There is also no nutrition for the growth of black pigs, and the effect of improving the immunity of the black pigs in northern Guizhou is not achieved. The black pork pigs in northern Guizhou are poor, which affects the economic benefits of black pig breeding in northern Guizhou
