Compound feed for ietalurus punetaus

Abstract

The invention discloses a Ictalurus punctatus compound feed, the contents of mass ratio of characteristic materials are as follows: vitamin A 0.005-0.007, vitamin D3 0.004-0.006, vitamin E 0.070-0.090, vitamin K3 0.002-0.004, vitamin B1 0.003-0.005, vitamin B2 0.005-0.007, vitamin B6 0.08-0.012, vitamin B12 0.001-0.003, nicotinamide 0.030-0.050, calcium pantothenate 0.10-0.30, folic acid 0.01-0.03, biotin 0.001-0.002, VC-phosphate 0.300-0.400, inositol 0.070-0.090, antioxidants 0.200-0.300, wheat-middlings 1.000-1.200, ferrous sulfate 0.400-0.600, copper sulfate 0.010-0.030, zinc sulfate 0.150-0.200, manganese sulfate 0.100-0.150, iodine 0.050-0.150, Se 0.050-0.070, cobalt chloride 0.010-0.030, magnesium sulfate 1.000-1.500, zeolite powder 5.0-6.0, xylo-oligosaccharide 0.008-0.012, bacillus licheniformis 0.01, weatings 90.-110., wheat-middlings 110-130, rice bran 75-85, soy bean powder 55-65, soybean meal 190-210, peanut meal 25-35, fish meal 95-105, cottonseed meal 75-85, rapeseed meal 110-130, gem meal 45-55, soybean oil 15-25, lysine 0.8-1.2, methionine 0.8-1.2, salt 2.0-2.5, betaine 3-5, allicin 0.1-0.3, choline chloride 1.0-2.0, calcium dihydrogen phosphate 15-25. Compared with other feeds, the usage rate of feed nutrient ingredients for Ictalurus punctatus is increased by 10-15%, feed coefficient is reduced by 5-10%, feed waste is reduced, nitrogen and phosphorus excretion of Ictalurus punctatus in the environment is reduced, at the same time the survival rate of Ictalurus punctatus is improved significantly.

Description

technical field [0001] The invention relates to a fish feed, in particular to a channel catfish compound feed. Background technique [0002] Channel catfish (Ictalurus Punctatus (Rafinesque), also known as Channel Catfish), belongs to Siluriformes (Siluriformes), Ictaluridae (Ictaluridae) fish. Channel catfish natural distribution areas are in the central watershed of the United States, southern Canada and parts of the Atlantic coast. Later, it widely entered the Atlantic coast, and now it is basically distributed in the entire United States and northern Mexico. The origin is large and medium-sized rivers with no pollution, sandy or gravel bottom, and fast flow. It can also live in brackish water. Now It is one of the main freshwater aquaculture species in the United States. In 1984, the Hubei Fishery Science Research Institute introduced it to my country. After several years of research and promotion of breeding, it has been confirmed that this fish is suitable for breeding i...

Problems solved by technology

[0003] Channel catfish from fry to adult fish in ponds where artificial breeding is the mainstay, fry, fingerlings and adult fish mainly eat artificial compound feed, but ordinary fish feed contains too much phosphorus, pollutes the water source, and the content of trace elements in the feed is not enough , the prevalence of channel catfish is too high
