Distiller's grains mixed granulated feed and production process thereof

Abstract

The invention discloses a distiller's grains mixed granulated feed. The distiller's grains mixed granulated feed is prepared from the following raw materials in parts by weight: 50-60 parts of corn, 25-30 parts of soybean meal, 30-40 parts of bajiu distiller's grains, 1-2 parts of calcium hydrophosphate, 0.5-0.6 part of a feed additive and 0.8-1 part of a premix. A production process of the distiller's grains mixed granulated feed comprises the following steps: step 1, fermenting baijiu distiller's grains and schizochytrium limacinum powder; step 2, mixing materials; and 3, performing granulating and drying. According to the invention, the baijiu distiller's grains and the schizochytrium limacinum powder are mixed and then subjected to microbial fermentation to prepare one of base materials of the feed. The content of protein in the distiller's grains is improved by controlling fermentation parameters. Meanwhile, the characteristic that traditional distiller's grains do not have DHA after fermentation is changed, and the quality of a feed product is improved. A feed additive is added into the feed, and power is provided for high-efficiency work of tissues such as muscle, brain, gonad and the like, and then growth performance of animals is improved. According to the invention, the value of the distiller's grains are fully explored and utilized, and very important significance isachieved on meeting requirements of breeding industry and agriculture and animal husbandry.

Description

technical field [0001] The invention belongs to the field of feed production, in particular to a distiller's grain mixed pellet feed and a production process thereof. Background technique [0002] Liquor is fermented from pure grains such as sorghum, corn, wheat, rice, barley or mixed raw materials. Liquor fermentation mainly converts the starch in the raw material, and less converts and utilizes the protein components in the raw material, which are basically preserved in the distiller's grains. Due to the concentration of fermentation (the raw material starch is utilized), the protein content (dry basis) of the distiller's grains can be doubled or more than that of the raw material, reaching about 20%. In addition to the high protein content, the amino acid composition of distiller's grains is relatively balanced, which is basically full price; the content of minerals in distiller's grains is also very rich, among which the main trace elements such as calcium and iron are ...

Problems solved by technology

[0003] However, distiller's grains also have obvious nutritional deficiencies and obstacles in application: 1. Fresh distiller's grains have large moisture content, high acidity, are perishable and deteriorate, are difficult to store and transport, and a large amount of distiller's grains are randomly stacked to seriously pollute the environment; 2. Directly used as The feed is extremely cheap in terms of sales price, resulting in a waste of economic value; 3. Distiller's grains contain about 50% of rice husks that are difficult to digest (mainly containing crude fiber and lignin), which are directly fed to livestock and poultry, which affects the digestion and absorption of animals

The current utilization of distiller's grains is still in the traditional direct fresh feeding, simple drying, single physical and single biological treatment, specifically including direct feeding of fresh distiller's grains, physical extrusion, physical adsorption, direct combustion, drying and crushing , the production of single-cell protein feed, the production of crude enzyme preparations, and the production of organic fertilizers, etc., all of which cannot improve the feasibility and value of the reuse of distiller's grains as a whole. Only a small part of distiller's grains is used as feed or fertilizer, and most If it is regarded as waste, if it is discharged directly, it will be a waste of resources and cause environmental pollution
