Compound feed specially used for sparus latus in intensive culture mode, and application of compound feed

Abstract

The invention discloses compound feed specially used for sparus latus in an intensive culture mode. The compound feed is prepared from the following components in parts by weight: 32-36 parts of fish meal, 10-15 parts of pet-grade chicken bone meal, 3-6 parts of spray-dried plasma globulin powder, 2-3 parts of enzymatic hydrolysate of fish dissolved pulp, 2-3 parts of squid paste, 5-8 parts of soybean protein concentrate, 3-5 parts of fermented soybean meal, 3-5 parts of corn protein powder, 10-15 parts of flour, 4-6 parts of wheat gluten powder, 1-2.5 parts of seaweed powder, 3-5 parts of refined fish oil, 1.5-2 parts of soybean oil, 2-3.5 parts of soybean phospholipid oil, 1.5-2 parts of calcium dihydrogen phosphate, 0.5-1 part of choline chloride, 0.1-0.2 part of bile acid, 1 part of a compound immune enhancer, 1 part of composite multi-vitamin premix, 1 part of composite multi-mineral premix and 0.05-1 part of fine unite bran. The compound feed provided by the invention can effectively increase the survival rate and yield of the sparus latus in high-density culture.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a special compound feed for yellowfin breeding which can improve the resistance of yellowfin seabream and is suitable for intensive cultivation. Background technique [0002] Yellow fin bream, also known as yellow wall, yellow foot stand, red wing and so on. It is a fish belonging to the bream family of Perciformes, which is widely distributed in the Red Sea, the coast of the Arabian Sea, India, Indonesia, Japan, North Korea, the Philippines and the coastal waters of China. It is one of the important economic fishes along the coast of South China. Yellowfin sea bream is rich in nutrition, beautiful in meat quality, and high in economic value. It is a popular edible fish and occupies a certain position in seawater and brackish water aquaculture. Since the 1980s, artificial breeding and seedling breeding have been successful, but so far the cultivation of yellowfin seabream has no...

Problems solved by technology

[0003] Farmers are constantly pursuing high yield and high income, and the stocking density is increasing year by year. However, due to the low grade of commercial feed and insufficient nutrition, the growth rate of yellowfin seabream is limited. Visceral nodules, liver necrosis, and exophthalmos caused by Pasteurella are very serious during the high temperature period. The annual loss due to disease accounts for 20-30% of the breeding production, and the loss rate in some areas is even as high as 80%.

In terms of disease prevention and control, antibiotics and other drugs are abused, and drug residues seriously affect food safety
