Powdery compound feed for increasing weight gain rate of eels

Abstract

The present invention discloses powdery compound feed for increasing weight gain rate of eels, and relates to the field of eel culture. The powdery compound feed comprises the following components in parts by weight: 50-55 parts of fish meal, 20-30 parts of cabbage caterpillar powder, 8-10 parts of chicken powder, 5-8 parts of corn protein powder, 8-10 parts of fermented soybean meal, 1.5-2 parts of monocalcium phosphate, 1-3 parts of mannan oligosaccharide, 3-5 parts of a vitamin mixture, 2-4 parts of a mineral substance mixture, 0.1-0.2 part of bile acid, 3-5 parts of soybean oil, 18-21 parts of pregelatinized starch and 1-1.5 parts of probiotics, wherein the fish meal is Russian fish meal, the chicken powder is Russian chicken powder, and the probiotics is a mixture of saccharomycetes, Clostridium butylicum and lactic acid bacteria. The cabbage caterpillar powder is adopted which comprises a high content of protein and a high content of methionine that is an essential amino acid, and supplements feed nutrients, makes feed amino acids more balanced, and improves the growth speed and weight gain rate of eels.

Description

technical field [0001] The invention relates to the field of eel breeding, in particular to a powdery compound feed for improving the weight gain rate of eels. Background technique [0002] Eel aliases: white eel, white eel, river eel, eel, green eel, wind steamed bun, Japanese eel, etc., eel is the meat or whole of eel, an animal of the eel family. Adult eels grow fast, round and cone-shaped in appearance, black in color and firm in body, and more artificially bred in recent years, with crispy meat. Eel is a fish that looks like a snake but has no scales. It is generally found in seas where brackish and fresh waters meet. It is one of the famous and special breeding species in my country. Eel grows in fresh water. Our country mainly relies on the natural eel fry from the Yangtze River for artificial feeding. Eel is a carnivorous fish, and likes to eat small fish, shrimps, crabs, rotifers, and aquatic insects in natural waters. [0003] The meat of eel is rich in protein,...

Problems solved by technology

[0004] At present, eel farming generally uses powder for feeding. The period suitable for eel growth is during the high temperature period in summer. A large amount of powder will pollute the water quality, resulting in frequent eel diseases, and the survival rate of eels is not high. In order to improve the survival rate of eels, farmers should reduce Morbidity, the method of reducing the feeding rate leads to low feed conversion rate and slow fat growth, which affects the weight gain rate of eels and reduces the growth rate of fish.
