Problems solved by technology

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 have brought great harm to human health
[0003] And at present, the eggs produced by large-scale breeding hens have high yield and large individual volume, but the taste and nutritional value are often not as good as eggs produced by ordinary farm hens, and there are also important problems such as the decline of immunity of laying hens, so how to Improving the immunity of laying hens, egg production rate, nutritional value and taste of eggs has always been a matter for research and development personnel to improve and improve
Although the nutrition of the existing feed additives for laying hens is relatively comprehensive, they lack medicinal ingredients to improve the body's immunity, improve organ functions, and prevent and treat diseases. The medicines used for the prevention and treatment of chicken diseases not only have a high cost, but also have certain effects. side effects, not commonly used
Antibiotic substitutes currently on the market, such as probiotics, oligosaccharides, enzyme preparations, natural plant extracts, etc., are still unable to completely and effectively replace the use of antibiotics in feed due to the limited efficacy of a single component

Embodiment 1

[0045] Embodiment 1: the preparation of compound biological feed additive

[0046] 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%. Fulvic acid is a kind of organic weak acid with aromatic structure. It contains many active groups, which can activate the activity of various enzymes, strengthen cell respiration, promote tissue metabolism, regulate physiological functions, regulate chicken body metabolism, and improve laying hens. There is a noticeable effect on production performance.

[0076] Effects of Compound Biological Feed Additives on Production Performance and Egg Quality of Laying Hens

[0077] 1,500 280-day-old healthy Hai-Line brown layer hens were randomly divided into 5 groups, with 5 replicates in each group and 60 chickens in each replicate. The control group was fed the basal diet, and the test I, II, and III groups were added 0.015% oxytetracycline, 0.02% extract compound preparation, 0.1% probiotics and the mixture of fermented insect excrement to the basal diet respectively. In the IV basal ration, the premix is ​​replaced with 5% compound biological compound biological feed additive of the present invention, and the others are the same. The basal diet is self-batching by the chicken farm, the control group and the test I, II, III groups add 5% premix of a certain brand, and the test IV group adopts the same raw materials and formula, but the 5% egg of the present invention used in the premix Compound biological feed additive for chickens....

Abstract

The invention provides a compound biological feed additive for laying hens, which belongs to the technical field of feed science and feed additives. The feed additive of the invention comprises: feed-grade fulvic acid, insect meal, fermented insect excrement, extract compound preparation, microbe Ecological preparations and carriers are compounded according to a certain proportion. The premix of the compound biological feed additive is used in the feed of laying hens, which can not only regulate the internal environment of the digestive tract of livestock and poultry, regulate the balance of the intestinal flora of the body, enhance the immune function of the body, and has the functions of antibacterial, anti-stress, enhancing immunity, improving In terms of production performance, the feed additive of the present invention is added to the diet of laying hens to improve the production capacity and self-immunity of laying hens, improve the feed conversion rate, thereby reducing drug residues and improving the quality of eggs. It is a new type of safe, reliable, green and environmentally friendly feed additive product. , the application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of feed science and feed additives, and relates to a biological feed additive, in particular to a compound biological feed additive for laying hens. 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. [0003] And at present, the eggs produced by large-scale breeding hens have high yield and large individual volume, but the taste and nutritional value are often not as good as eggs pr...
