Preparation method and application of biological feed additive with nutrition and immunocompetence

Abstract

The invention discloses a preparation method of a biological feed additive with nutrition and immunocompetence. The biological feed additive with nutrition and immunocompetence comprises the following components: 0.05 to 0.1% of aerobic bacteria, 0.05 to 0.1% of anaerobic bacteria, 0.3 to 0.5% of fermenting promoter, 5 to 15% of soybean meal, 5 to 10% of molasses, 15 to 25% of DDGS (Distillers Dried Grains with Soluble), 10 to 30% of cassava residue, 20 to 50% of bran meal, 5 to 15% of bran, 5 to 15% of maize cob powder, and 20 to 40% of maize slurry protein. The preparation method comprises the processes of activating bacteria, crushing raw materials, aerobically fermenting for 1 to 2 days, and then anaerobically fermenting for 3 to 7 days. The prepared biological feed additive brings piglet, medium and large pigs and sheep with high nutrition value, is high in palatability, and has effects of accelerating growth, improving intestinal health, controlling diarrhea, controlling constipation of sow, increasing birth weight and weaning weight of the piglet, improving the quality of eggshell and egg yolk, controlling feed-containing faeces, raising the lactation level of dairy cattle, as well as increasing butterfat and protein content.

Description

technical field [0001] The invention relates to the field of feed biotechnology, and in particular provides a preparation method and application of a biological feed companion with nutritional and immune activity. Background technique [0002] The micro-ecological living bacteria preparation has the functions of regulating the balance of intestinal flora, improving the comprehensive immune level of the body, and improving the production performance of livestock and poultry. With the continuous recognition of animal intestinal microecology research results in the field of animal nutrition and feed science, it has gradually become normal to add microecological live bacteria preparations to feed formulations. However, in the actual breeding production of probiotics, its effectiveness is affected by many factors such as storage conditions, product quality stability, breeding management level, breeding conditions, and the quality of employees. In the production of livestock and ...

Problems solved by technology

[0004] However, the vast majority of fermented feed manufacturers have problems such as poor infrastructure conditions, unprofessional technicians, no scientific testing conditions, complex sources of strains, and low nutritional levels of raw materials.

In addition, they have insufficient understanding of the probiotic function and mechanism of action of probiotics, and do not understand the nutritional requirements and intestinal microecological characteristics of different growth stages of different animals such as pigs, chickens, cattle, and sheep.

As a result, the selection of fermentation base materials is not targeted, the combination of bacteria and fermentation accelerators is unscientific, the fermentation process is unreasonable, and the nutritional properties of the raw materials themselves cannot be fully utilized during use. The intestinal regulation, growth promotion, and The immune enhancement function cannot be fully reflected, which will have an adverse impact on the development and promotion of this type of product
