General-purpose high-efficiency bulking compound feed for culter alburnus and pelteobagrus fulvidraco

Abstract

The invention relates to a general-purpose high-efficiency bulking compound feed for a culter alburnus and a pelteobagrus fulvidraco. The compound feed is prepared from the following raw materials in portions by weight: 13-35 portions of imported steam fish meal, 10-25 portions of imported direct-heat fish meal, 3-5 portions of maggot powder, 2-8 portions of corn protein powder, 5-10 portions of soybean meal, 2-8 portions of fermented soybean, 2-4 portions of soybean meal, 3-8 portions of cottonseed protein, 2-5 portions of peanut meal, 2-5 portions of colza meal, 3-8 portions of meat / bone meal, 2-5 portions of sleeve-fish visceral meal, 23-33 portions of high protein flour, 1.0-3.0 portions of soya bean lecithin, 2.0-5.0 portions of sea fish oil, 0.4-1.0 portion of choline chloride (50%), 0.1-0.3 portion of vitamin C-phosphate (35%), 0.5-1.5 portions of calcium biphosphate, 0.2-0.5 portion of compound multi-vitamin, 0.5-1.5 portions of composite mineral salt, 0.04-0.2 portion of lutein (20%), 0.1-0.3 portion of phagostimulant, 0.1-0.3 portion of micro-ecological preparation, 0.1-0.3 portion of beta-1,3 glucan, 0.01-0.04 portion of phytase and 0.04-0.08 portion of non-starch polyase. The feed can meet all the nutritional requirements of culturing the culter alburnus and the pelteobagrus fulvidraco, so that fish bodies can grow quickly, high feed conversion rate can be achieved, and the coefficient of the feed ranges from 1.2 to 1.4. By using the feed, the immunity performance and the anti-stimulation capability of the culter alburnus and the pelteobagrus fulvidraco can be obviously enhanced, the energy of the fish bodies can be ensured, and the survival rate is improved by 5-10%.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a general-purpose high-efficiency puffed compound feed for red catfish and yellow catfish. Background technique [0002] Red catfish, commonly known as white fish, and yellow catfish, commonly known as anchovy. These two fish are representative high-grade economic fish in the Yangtze River Delta of my country. Because the meat of these two kinds of fish is delicious, they can be cultured with artificial compound feed throughout the whole process. Therefore, they are widely cultured in Zhejiang, Shanghai and other places, and most of them are mixed cultures of two kinds of fish. However, there are very few international and domestic researches on extruded compound feeds for red catfish and yellow catfish. The existing brands of compound feeds on the market have high coefficients and are expensive, resulting in a sharp increase in breeding costs; due to the lack of basic research, ...

Problems solved by technology

However, there are very few international and domestic researches on extruded compound feeds for red catfish and yellow catfish. The existing brands of compound feeds on the market have high coefficients and are expensive, resulting in a sharp increase in breeding costs; due to the lack of basic research, breeding yellow catfish The body color problem of catfish has always been difficult to solve. Yellow catfish cultured with extruded feed often have symptoms such as "albino" or "banana yellow", which greatly affects the commodity value of yellow catfish and further reduces the breeding profit; at the same time, due to High-density intensive farming, the survival rate of these two fish is relatively low

The above three reasons have seriously hindered the further development of these two fish farming industries.
