Functional compound dietary fiber, preparation method and application

Abstract

The invention relates to the technical field of feed, in particular to a functional composite dietary fiber, a preparation method and application. The functional composite dietary fiber provided by the invention is prepared from composite dietary fiber, composite grease, composite lactic acid bacteria and carriers. Wheat bran in the conventional feed can be replaced; through a cooperated matching effect, the intestinal environment can be improved; the intestinal tract movement can be promoted; the feed utilization rate is improved; the intestine lubrication and bowel relaxing effects can be achieved; meanwhile, the production performance of the functional composite dietary fiber can be enhanced. The functional composite dietary fiber provided by the invention can be added to pig feed of stock boars, replacement sows, pregnant sows and lactation sows; the sperm viability of the boars can be enhanced; the constipation rate of sows is reduced; the milk yield is improved; the piglet survival rate, the piglet body weight and the like are improved.

Description

Technical field[0001]The invention relates to the field of feed technology, in particular to a functional composite dietary fiber, a preparation method and an application.Background technique[0002]Dietary fiber is the carbohydrate component of feed that is slowly digested or not digested by animals. It has an important physiological role in nutrition and an important role in protecting animal health and prolonging the lifespan of the body. Reasonable selection of dietary fiber can promote animal intestinal health, improve animal production performance, and provide humans with healthier and safer animal products. Increasing the fiber content in the feed can reduce the chance of suffering from gastrointestinal diseases. At the same time, the enlarged diet makes the sow feel full, so after eating the daily ration, the mood is stable, which lays a good foundation for improving reproductive performance.[0003]However, there are generally two types of fiber in pig feed. One type is provide...

Problems solved by technology

One type is provided by the bran in the traditional feed. The bran fiber needs to be tightly combined with the lignin in the cell wall. The fiber cannot be fully separated and affects its function, and the fiber content is low, less than 9%, which cannot meet the nutritional needs of pigs.

The other is pure cellulose additives, obtained through wood processing, mainly wood fibers, composed of insoluble fibers, with a cellulose content greater than 80%, and a small amount of addition, but it is not easy to mix in the feed, and it is harmful to the intestinal tract Stimulation is intermittent and not available to the large intestine
