Combined bacteria fermented bran high protein predigesting feed and preparation method

Abstract

The invention discloses combined bacteria fermented bran high protein predigesting feed and a preparation method. The combined bacteria fermented bran high protein predigesting feed consists of 30 to 70 weight percent of fermented wheat bran and 30 to 70 weight percent of composite bacteria culture material. The preparation method comprises: preparing the fermented wheat bran and the composite bacterial culture material by using dry corn pulp fermented by solution of combined bacteria and wheat bran; and mixing the fermented wheat bran and combined bacteria culture material. The prepared granulated feed is convenient to store, package and transport, has high density, small volume and high nutrient concentration, and thereby improves the feed intake of animals; and the addition of the dry corn pulp fermented by the solution of the combined bacteria and the wheat bran increases the coarse protein content and beneficial bacterium colonies in the feed, improve the beneficial bacterium colonies in intestinal tracts, reduce diseases, improve physical properties of some nutrients in the feed and improve digestion and absorption rates and nutrient utilization rate to a certain degree.

Description

technical field [0001] The invention relates to a method for preparing high-protein predigested feed, in particular to fermenting bran high-protein predigested feed with compound bacteria and the preparation method. technical background [0002] With the continuous development of animal husbandry, people's demand for animal products has increased, and small-scale animal product production is far from meeting the growing needs of people. In the past, most animals were raised in free range or outdoors, and most animals were collected freely in the wild. Food, energy and crude protein intake cannot meet growth needs. Recently, with the vigorous development of animal husbandry, the popularity of various premixed feeds and complete feeds, but due to the different digestion and absorption of various nutrients by animals in different growth stages, it is necessary to meet the requirements of different growth stages of animals. All purpose feed. [0003] Most of the feeds currentl...

Problems solved by technology

[0003] Most of the feeds currently on the market are non-fermented protein raw materials, which are directly produced by high-temperature granulation, which has low protein digestion and utilization, does not contain digestive enzymes and live bacterial preparations, and inhibits fermentation metabolites and growth-promoting factors. growth, and a large amount of steam is required in the production process, resulting in excessive moisture content in the feed, prone to mildew, and the high temperature in the pelleting process inactivates digestive enzymes and live bacteria

At the same time, most feeds currently on the market lack beneficial microbial flora and cannot promote the digestion and absorption of nutrients in the intestinal tract. The preparation process is complicated, the raw materials are expensive to purchase, the crude protein content is low, the production cost is high, and the breeding cost is reduced.
