Method for preparing high-moisture fermented granulated feed for pigs

Abstract

The invention discloses a method for preparing a high-moisture fermented granulated feed for pigs. The feed is prepared from the following raw materials in percentage by weight: 65-70% of corn and 30-35% of fermented protein feed; and the method comprises the following steps: firstly, fermenting bean pulp, bran and a vinasse protein feed by using compound microbial liquid so as to obtain a fermented protein feed; and then, mixing the fermented protein feed with the corns. The feed prepared by using the method is a granulated feed which is easy to store, package and transport; because the density of the granulated feed is large, the volume thereof is reduced, and the nutrient concentration thereof is high, so that the feed intake of animals is correspondingly increased; and the crude protein content of the feed and the generation of beneficial microorganisms can be increased by simply fermenting the bean pulp and bran by using complex microorganisms, thereby improving the beneficial microorganisms in intestinal canals, reducing the occurrence of diseases, improving the physicochemical properties of some nutrients in the feed, and enhancing the digestibility of the feed and the utilization rate of nutrients in the feed to some extent.

Description

technical field [0001] The invention relates to a preparation method of fermented feed, in particular to a preparation method of high-moisture fermented granular feed for pigs, which is mainly used for pigs. 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 currently on the...

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 low feed moisture content, pigs need to re-supply water after eating, increasing labor, and poor palatability, resulting in decreased feed intake of pigs, increased feed consumption, and increased pig metabolism energy consumption and increase production costs; the high temperature in the granulation process inactivates digestive enzymes and live bacteria

At the same time, most feeds currently on the market lack beneficial 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.
