Mixed feed for improving stress resistance of grass carp

Abstract

The invention relates to a mixed feed for improving stress resistance of grass carp, which can significantly reduce the stress-induced death of grass carp and increases the farming benefit. The mixed feed comprises the following materials in parts by weight: 160-200 parts of bean cake, 250-300 parts of rapeseed cake, 160-200 parts of flour, 100-140 parts of cotton cake, 40-50 parts of fish meal, 70-120 parts of cornstalk full ethyl alcohol grains, 20-25 parts of calcium dihydrogen phosphate, 15-20 parts of edible fat and oil, 1-2 parts of 50% of coated choline chloride, 0.05-0.15 part of high temperature-resistant complex enzyme preparation, 1-2 parts of complex microelements, 2-3 parts of 40% of coated lysine, 1-1.2 parts of vitamin complex for freshwater fish, 0.08-0.12 part of L-carnitine and 0.2-0.5 part of an antioxidant.

Description

1. Technical field: [0001] The invention relates to a feed, in particular to a compound feed for improving the anti-stress ability of grass carp. 2. Background technology: [0002] The current products have the following deficiencies: 1. Grass carp farming tends to use high-protein rations, which eventually lead to high crude protein content and amino acid imbalance in the grass carp compound feed, and protein is metabolized in large quantities as an energy source. Grass carp fatty liver later appeared; 2. The ratio of calcium and phosphorus in the high-protein diet was not good, and grass carp with a big belly appeared, and the fat accumulation in the mesentery was serious, which easily induced hepatic ascites and hepatobiliary syndrome, resulting in continuous and sporadic death of grass carp; 3. Vitamins in the diet It cannot meet the needs of rapid growth, resulting in the decline of grass carp's anti-stress ability, slow physical recovery after infection, and slow growt...

[0002] The current products have the following deficiencies: 1. Grass carp farming tends to use high-protein rations, which eventually lead to high crude protein content and amino acid imbalance in the grass carp compound feed, and protein is metabolized in large quantities as an energy source. Grass carp fatty liver later appeared; 2. The ratio of calcium and phosphorus in the high-protein diet was not good, and grass carp with a big belly appeared, and the fat accumulation in the mesentery was serious, which easily induced hepatic ascites and hepatobiliary syndrome, resulting in continuous and sporadic death of grass carp; 3. Vitamins in the diet It cannot meet the needs of rapid growth, resulting in the decline of grass carp's anti-stress ability, slow physical recovery after infection, and slow growth rate in the later stage, which affects the breeding efficiency

4. Lack of enzyme preparations to improve protein utilization, ignoring intestinal nutrition, loss of a large amount of nutrients, causing eutrophication of aquaculture water, massive proliferation of harmful algae, and increased risk of secondary hazards
