Environment-friendly black carp feed

Abstract

The invention provides environment-friendly black carp feed, and belongs to the technical field of processing of fish feed. The environment-friendly black carp feed is mainly prepared from the following raw materials according to certain mass ratio: dried grass meal, rape seed cake, wheat bran, corn flour, linseed cake, earthworm meal, coprophagous beetle meal, soybean curb residue, monosodium glutamate protein, bone meal, egg shell meal, fishy flavoring agent, edible salt, vitamin additive and traditional Chinese medicine additive; the traditional Chinese medicine additive is mainly prepared from folium isatidis, honeysuckle flower, herba violae, uraria crinita, fructus seu herba Physali alkekengi, sword brake herb, herba ophioglossi, leaves of camphor trees, rhizoma ploygonatum cirrhifolium, thaiictrum delavayi Franch and cortex meliae. The environment-friendly black carp feed has the advantages that balance and comprehensive nutrients are contained; by adding the traditional Chinese medicine additive, the disease-resistant capability of fishes is improved, and the survival rate is improved; the palatability is good, the conversion rate is high, the food intake amount of the fishes is increased, and the growth of the fishes is accelerated; the utilization rate of feed is improved, the feeding amount of feed is reduced, the feeding cost is reduced, and the damage to culture water quality by feed residues is avoided.

Description

【Technical field】 [0001] The invention belongs to the technical field of fish feed processing, and in particular relates to an environment-friendly herring feed. 【Background technique】 [0002] Aquaculture is a production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding management. Among them, the selection of feed has an important impact on the quality of breeding. In recent years, aquaculture has gradually become popular, especially freshwater fish farming, which has developed rapidly and the scale of farming has continued to expand. [0003] Herring is one of the "Four Major Fishes" freshwater cultured in my country. Its meat is delicious, and it has therapeutic and health effects such as removing dampness and numbness, nourishing qi and neutralizing it, and is widely loved by consumers. In recent years, the demand fo...

Problems solved by technology

However, most of the existing herring feeds have unreasonable nutrient content and ratio, and the conversion rate is low, resulting in the low utilization rate of the nutrient components of the herring feed, which will easily cause the deterioration of the breeding water quality, the decline of the health level of aquatic products and the resistance to diseases. The increase in the frequency of diseases due to the reduction of labor force leads to the blind use of drugs by producers and the reduction of growth efficiency, which in turn leads to a series of problems such as a decline in the quality of aquaculture products, a sharp increase in costs, drug residues, and eutrophication of water bodies.
