Low-cost crucian feed

Abstract

The invention discloses low-cost crucian feed. The low-cost crucian feed is composed of the following matters in parts by weight: 150-200 parts of farm manure, 60-70 parts of plant straws, 30-40 parts of soybean meal, 40-50 parts of alfalfa hay, 50-60 parts of zea mexicana, 2-3 parts of a vitamin additive, 2-3 parts of a special feeding attraction additive for crucian and 3-5 parts of phospholipid oil. The feed disclosed by the invention has low cost; raw materials are common and easy to obtain; wastes are reused so that the environment is protected; the feed has a relatively good nutritive value and the water quality is also improved; the disease-resisting capability of the crucian is improved and the economic value of the feed is relatively good.

Description

Technical field [0001] The invention belongs to the field of fish feed, and particularly relates to a low-cost crucian carp feed. Background technique [0002] The cultured crucian carp is relatively concentrated in East my country, and the market consumption habits are preferably large-sized crucian carp, and the earlier it goes on the market, the higher the price per catty, so the nutrient level of feed is high. Usually 8-12% of fishmeal is used in the bred feed, and the dependence on fishmeal is very high. In recent years, fishmeal producing countries have strengthened the protection of marine fishery resources, and the output has declined. The price of imported fishmeal is 1,1000-14,000 yuan per ton, and the price of domestic fishmeal is as high as 9,000-12,000 yuan per ton. In the future, the output of fishmeal will be flat or decreasing, and the feed industry will continue to grow. The contradiction between supply and demand between the two will become increasingly promine...

AI Technical Summary

Problems solved by technology

In the future, the output of fishmeal will remain flat or decrease, and the feed industry will continue to grow. The contradiction between supply and demand between the two will become increasingly prominent. The rising price of fishmeal will lead to huge pressure on the feed cost of crucian carp. In the process of freshwater fish farming, the cost of feed It accounts for 60-70% of the total cost, and the profit of farmers is greatly reduced

In recent years, in order to reduce the cost of feed, people have used some low-value raw materials unscientifically, which has greatly affected the attraction and growth of fish, resulting in reduced food intake, slow growth, and high mortality. It is less than the commodity specification, which further affects the profit of farming. This situation seriously hinders the further development of freshwater fish farming and feed manufacturing industry
