Feed for preventing hemorrhage of grass carp under high-density feeding condition

Abstract

The invention discloses a feed for preventing hemorrhage of grass carp under a high-density feeding condition. The feed consists of the following components in percentage by mass (100% in total): 16.08 percent of rice bran, 3.0 percent of unite bran, 10.0 percent of wheat, 0.22 percent of choline chloride, 11.0 percent of corn germ meal, 3.0 percent of bean pulp, 29.0 percent of cottonseed meal, 17.4 percent of rapeseed meal, 4.0 percent of monosodium glutamate and yeast, 2.0 percent of meat and bone meal, 1.59 percent of monocalcium phosphate, 1.5 percent of phospholipid oil, 0.01 percent ofallicin, 0.2 percent of Chinese medicinal herbal preparation, and 1.0 percent of premix. Sodium bicarbonate and the Chinese medicinal herbal preparation are added into the feed, dosages of vitamin K3, vitamin C, vitamin B1 and vitamin B6 in the feed prescription are increased, the resistance of a fish body can be reinforced after the feed is used, the immunity of the fish body is improved, the survival rate is improved, and occurrence of the hemorrhage of grass carp is prevented, so that the production level and economical benefit can be improved.

Problems solved by technology

However, due to the grass carp fed with concentrated feed under high-density conditions, the physique of the fish body is significantly reduced, and various diseases, especially grass carp hemorrhagic disease, are the main diseases that plague grass carp under high-density intensive breeding conditions. Benefits have a greater impact
