Embodiment 1

[0029] Embodiment 1: the preparation of compound biological feed additive

[0030] A. Preparation of feed grade fulvic acid: provided by Inner Mongolia Yongye Biotechnology Co., Ltd., using natural weathered coal and lignite as raw materials, using modern biotechnology to highly purify natural fulvic acid products, its main component is fulvic acid The mass percentage content is greater than 40%;

[0031] B. Preparation of Chinese herbal medicine extracts: astragalus polysaccharide (APS), dandelion extract and honeysuckle extract.

[0032] Preparation of Astragalus extract: Astragalus removes impurities, chops, adds 8 to 10 times the volume of water to soak for 4 hours, reflux extraction for 2 hours, collects the filtrate by filtration, and adds 5 times the volume of water to the filter residue for reflux extraction After 2 hours, the filtrate was collected by filtration, the filter residue was discarded and the filtrate was combined, and then separated with a macroporous ads...

Embodiment 2

[0039] Embodiment 2, the impact of compound biological feed additive on dairy cow production performance and milk quality

[0040]From 100 adult Holstein dairy cows, 20 adult cows in the early stage of lactation were selected as experimental cows, with an average lactation age of 65 days. According to the principle of similarity in age, parity, gestation period, milk production and body weight, random Divided into experimental group and control group, 10 in each group. The experimental group and the control group were fed intensively in separate troughs in the barn respectively, and were reared by special personnel. The feeding and management conditions were the same. The basic formula of the diet was the same for the experimental group and the control group, but different additives were used. Composition of the basic ration: the ratio of the ration to coarse grain was 40:60, and each head was fed with 18kg of silage corn and alfalfa hay, and 12kg of supplementary concentrate....

Abstract

The invention discloses a compound biological feed additive for dairy cows, and belongs to the technical fields of forage science and feed additives. The feed additive disclosed by the invention comprises a feed-grade fulvic acid, a Chinese medicinal herb extract, probiotics and a carrier. The feed additive disclosed by the invention is capable of enhancing the immunity of dairy cows, significantly improving the milking performance, solving the problem of milk supply shortage, improving the milk quality and reducing the bad effects on people and environment caused by the dairy cows after being added to diet of dairy cows, is a novel safe, reliable and green feed additive product, and has a good application prospect.

Description

technical field [0001] The invention relates to a compound biological feed additive for dairy cows, belonging to the technical field of feed science and feed additives. Background technique [0002] People's understanding of food safety is gradually deepening, and people are paying more and more attention to green and nutritious animal products. For a long time, a large number of chemically synthesized feed additives and chemicals, such as antibiotics, growth-stimulating hormones and preservatives, have been widely used in feed, which has brought about great negative effects while promoting the development of animal husbandry, especially the resistance caused by the abuse of antibiotics. Drugs and drug residues bring great harm to human health. Therefore, seeking safe, efficient and environmentally friendly alternatives to antibiotics, reducing the incidence of mastitis, reducing the use of antibiotics, increasing milk production and improving cow production performance hav...
