Problems solved by technology

[0003] In order to improve the egg production and egg quality of poultry to meet people's needs, technicians in the farming field adopt a variety of feeding methods; for example, improve the work and rest time of poultry through light and other conditions, thereby improving their egg production rate and egg quality , but can not improve the quality of eggs; in response to this problem, adding nutritional supplements to the feed has become a popular means, such as directly adding calcium carbonate, potassium iodide, trace element additives, amino acid additives, vitamin additives and other trace elements and additives to the feed. Mineral salts, this kind of addition can quickly increase the nutritional content of eggs in a short period of time, but in the long run, it will reduce the absorption of the original nutrients in the feed by poultry, weaken the ability of poultry to digest and absorb, and then lead to the occurrence of various diseases; in addition, excessive addition Nutritional supplements will not only cause excessive components to be excreted with excrement, reducing the utilization rate; they will also have a toxic effect on poultry; The physiological differences of the human body are quite large, and the traditional Chinese medicine prescriptions that have better effects on the human body may not be suitable for poultry. Traditional Chinese medicine prescriptions are not universally applicable. Adding traditional Chinese medicine ingredients to poultry diets may improve the egg production rate and egg quality of poultry in a short period of time, and may not achieve the desired effect; blind addition of traditional Chinese medicine ingredients may also lead to Physiological disorders of poultry, resulting in poultry death, decreased egg production quality, irregular laying time, etc., cannot be applied to large-scale farming

Abstract

The invention discloses a compound fermented feed additive for egg-laying poultry as well as a preparation method and an application of the additive and belongs to the technical field of feed additives. The compound fermented feed additive for egg-laying poultry is prepared from components in parts by weight as follows: 22-25 parts of fermented sunflower seed meal, 15-20 parts of fermented alga powder, 2-4 parts of oyster powder, 1-3 parts of yellow mealworm powder, 0.05-0.1 part of soybean isoflavone, 0.1-0.3 part of carboxymethyl chitosan and 0.05-0.1 part of perilla oil. The compound fermented feed additive for egg-laying poultry can increase the egg laying rate of the poultry, improve the egg laying property and further improve the laid egg quality. The compound fermented feed additivecan promote digestive absorption of nutrient substances and enhance immunity by regulating internal environments of intestinal tracts of the poultry and promoting growth and propagation of probiotics.
