An animal complex protein and its application

Abstract

The invention relates to animal compound protein. The animal compound protein is characterized containing meat and bone meal, blood powder, chicken powder and fermented silkworm chrysalis meal. The animal compound protein comprises the following components in parts by weight: 3.42-3.83 parts of the meat and bone meal, 4.18-4.54 parts of the blood powder, 11.62-13.35 parts of the chicken powder and 5.11-6.19 parts of the fermented silkworm chrysalis meal. In the preparation process, all the components are ground into fine powder and are sieved by a sieve of 80 meshes; the components are respectively weighed and are gradually and uniformly mixed. The efficient animal compound protein provided by the invention can effectively replace fish meal protein in scophthalmus maximus feed; the survival, the opisthosoma weight, the specific growth rate, the hepatosomatic index, the organ index and the condition factor of scophthalmus maximus are not influenced; all indexes in blood serum are not influenced; the body composition of regular fish bodies of the scophthalmus maximus is also not influenced. The aims of lowering the price of the feed and saving the cultivation cost are realized and theoretical foundation is provided for the sustainable development of aquaculture.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to an animal compound protein, namely a high-efficiency animal compound protein for turbot (Scophthalmus maximus) feed. Background technique [0002] Turbot is a typical carnivorous fish with tender and delicious meat, high nutritional value and fast growth. It is a valuable cold-water economic fish. good economic and social benefits. However, turbot has a high demand for protein nutrition, and the demand for fishmeal in the prepared artificial feed is large, resulting in an increase in feed cost. With the promotion of intensive farming, the high cost of feed has always been a concern of farmers; and as the main protein source of compound feed, fishmeal resources are increasingly in short supply, resulting in an imbalance between supply and demand. For a long time, the feed price has seriously hindered the development of the turbot farming industry. Therefore, the development of new...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of high animal compound protein, can effectively replace the fish meal in the turbot feed, and solve the problems such as amino acid deficiency or amino acid unbalance in the single protein source replacement fish meal process, thus make up for prior art insufficient
