Problems solved by technology

Because chicken meal, meat and bone meal, feather meal and blood meal and other livestock and poultry animal protein raw materials have poor palatability compared with fish meal, and the composition of essential amino acids is unbalanced, the use of existing alternative methods can greatly reduce the amount of fish meal in the feed (remove the amount of fish meal in the formula) The proportion of fishmeal > 50%) often leads to a decrease in the growth performance of farmed fish
In addition, the nutrient composition of animal protein raw materials of livestock and poultry often fluctuates due to the change of raw materials. When directly replacing the fish meal in the feed formula with cheap animal protein raw materials of livestock and poultry, it is often necessary to adjust the feed formula. Great inconvenience caused by production

Abstract

The invention relates to a composition of mixed animal protein which can be used for a substitution for aquatic animal compound feed, in particular to substituting for the fishmeal in fish compound feed. The composition of mixed animal protein comprises by weight portion: 100 portions of chicken meal, 40-80 portions of meat and bone meal, 20-50 portions of blood meal, 0.5-2 portions of methionine, 0-30 portions of feather meal and 0-4 portions of attractant. The invention also relates to a preparation method for the composition of mixed animal protein and the application thereof in preparation of aquatic animal feed. Taking advantage of the composition of mixed animal protein of the invention, 50-100 percent of fish meal in the fish compound feed can be directly replaced.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a compound feed for aquatic animals, in particular to a mixed animal protein composition of fish meal in the compound feed for fish, a preparation method and its application in preparing feed for aquatic animals. Background technique [0002] Compound feeds for fish tend to contain high levels of protein. The protein in the feed can be provided by fish meal, livestock and poultry animal protein raw materials (chicken meal, meat and bone meal, feather meal and blood meal, etc.) and vegetable protein raw materials (soybean meal, rapeseed meal and cotton meal, etc.). Fish meal has high protein content, balanced composition of essential amino acids, and good palatability. It is the best protein raw material in animal compound feed and has been widely used in the production of aquatic animal compound feed. my country needs to import a large amount of fishmeal every year for the preparation o...
