Abstract

The invention relates to a low-starch puffing compound feed for increasing the growth speed and survival rate of large yellow croakers. The low-starch puffing compound feed comprises Russian white fish meal, Peru fish meal, American chicken meal, wheat gluten, corn gluten meal, soybean meal, high-gluten flour, cassava starch, enzymatic fish soluble slurry, refined fish oil, soybean lecithin, monocalcium phosphate, a vitamin premixture, a mineral salt premixture, choline chloride, lutein, an antioxidant and a mildew preventive. The starch content of the puffing compound feed for the large yellow croakers, disclosed by the invention, is obviously lower than that of a commercial material sold in the market, so that the growth speed of the large yellow croakers can be remarkably increased, theabnormal deposition of fat in livers is reduced, the morbidity and mortality rates of hepatobiliary syndromes are reduced, and the survival rate of a breeding process is increased.

Description

technical field [0001] The invention relates to a low-starch puffed compound feed and a preparation method thereof, in particular to a low-starch puffed compound feed which improves the growth and survival of large yellow croakers and a preparation method thereof. Background technique [0002] Large yellow croaker (Pseudosciaena crocea R.) belongs to Perciformes, Pseudomonas family, yellow croaker genus, commonly known as yellow croaker, cucumber fish, large yellow flower, etc. and the northern part of the South my country Sea. Large yellow croaker has delicious meat, rich nutrition and golden color, and is favored by consumers and aquaculture farmers. As of 2017, the annual output of large yellow croaker is about 180,000 tons, the direct output value is about 10 billion, and there are more than 300,000 direct and indirect employees. Large yellow croaker has been the largest mariculture fish in my country for many years. [0003] At present, the bait for artificially cultur...
