Silver carp feed additive

Abstract

The invention discloses a silver carp feed additive, and belongs to the technical field of aquaculture. The silver carp feed additive is prepared from the following raw materials in parts by weight: 10 parts of snowflake-shaped powder (a bait made of dehydrated, dried and puffed potato flour) or white powder (a bait made of animal and vegetable proteins with an attractant), 5-10 parts of green grass, 10 parts of vinegar dregs, 7 parts of bone meal, 7 parts of eggshell powder, 20 parts of Chinese sorghum protein powder, 15 parts of rapeseed meal, 10 parts of wheat bran, 6 parts of rice bran, 5 parts of maggot meal, 0.5 part of polysaccharidase, 1 part of tenebrio molitor amino acids, 10 parts of dried orange peel, 8 parts of radix astragali, 7 parts of radix aucklandiae, 8 parts of radix angelicae dahuricae, and 1 part of edible salt. The snowflake-shaped powder or the white powder and the green grass are adopted in the silver carp feed additive so as to reduce density of feeds and improve atomization performance of the feeds, and thus, the silver carp feed additive increases feed intake of the silver carps, and improves growth level and fish production of the silver carps.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a silver carp feed additive. Background technique [0002] Silver carp is one of the main freshwater aquaculture fishes in my country and is distributed in major water systems across the country. Silver carp is a large freshwater fish raised artificially, with fast growth, few diseases and high yield. Modern large-scale aquaculture methods have increased production speed, but they have also brought many problems. Antibiotics are increasingly used to combat aquatic animal diseases. The positive effects of antibiotics are mainly reflected in the prevention and treatment of aquatic animal diseases, promotion of growth, and conservation of nutrients. In particular, the application of antibiotics has effectively controlled the occurrence of many aquatic diseases and promoted the development of aquaculture. However, due to the continuous use of antibiotics, it is ea...

Problems solved by technology

[0004] In addition, silver carp has the habit of living in the upper layer of the water, so it should float and disperse on the water surface for the convenience of eating. The existing feed does not have the atomization and dispersion characteristics that match silver carp, which affects the feeding efficiency and quality
