Feed composition as well as preparation method and application thereof

Abstract

The invention discloses a feed composition as well as a preparation method and application thereof, and belongs to the technical field of feeds, the feed composition comprises the following raw materials: astragalus sinicus, rice straws, soybean curb residues, a microbial preparation, porous zeolite, rhizoma acori graminei, artemisia apiacea, betel nuts, garlic and fennel; weighing rhizoma acori graminei, artemisia apiacea, betel nut and fennel, crushing, sieving, soaking, and decocting to obtain a composition liquid medicine; weighing garlic, crushing the garlic, and adding water for extraction to obtain garlic juice; mixing the composition liquid medicine with the garlic juice, and then adding the porous zeolite for adsorption; weighing astragalus sinicus and rice straw, crushing, adding soybean curb residue and a microbial preparation, fermenting, and mixing an obtained fermentation product with porous zeolite adsorbed with a traditional Chinese medicine composition to obtain the feed composition. The feed composition provided by the invention can be used in a rice-fish integrated planting and breeding system as an aquatic feed and a rice fertilizer at the same time, can effectively improve the survival rate of small-size fries, and improves the yields of rice and fishes.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed composition and a preparation method and application thereof. Background technique [0002] Rice field fish farming, as a comprehensive farming model, first existed in mountainous or rural areas, and was mainly carried out on a small scale by farmers. However, with the rapid economic development and the improvement of people's living standards, producers have continuously increased their requirements for the output per unit of land and food quality. Require. However, in the process of expanding the scale and pursuing the increase of output, some problems also appeared. Although there is a relationship between rice and aquatic animals in the rice-fishing integrated planting and breeding system, there is also a contradictory aspect, which is manifested in the need to use certain chemical fertilizers or other fertilizers (thus releasing some of them into the water ...

However, in the process of expanding the scale and pursuing the increase of output, some problems also appeared at the same time

Although there is a relationship between rice and aquatic animals in the rice-fishing integrated planting and breeding system, there is also a contradictory aspect. It is manifested in the need to use certain chemical fertilizers or other fertilizers to increase the yield of rice (which will release some fertilizers into the water body). ammonia nitrogen, etc.), and aquatic animals cannot tolerate high concentrations of ammonia nitrogen. Therefore, it is very important and necessary to develop a material that can simultaneously improve rice production and farmed animal production in the rice-fishing integrated planting and breeding system.

[0003] When feeding fry in conventional simple fish farming, you can directly put in small fry with a length of 3 to 5 cm. The cost of fry is low, and the survival rate of fry is high. The comprehensive breeding environment is much more complicated than that of a simple fish pond, and there are more types of microorganisms in the environment. However, the fry are too small and have poor resistance, which makes it difficult for them to survive in this complex environment, and it takes a long time to raise them. Large-scale fry with a body length of more than 10cm and increasing the amount of stocking can ensure a better yield, which undoubtedly increases the cost
