Abstract
The invention discloses an ictalurus punctatus fry starter feed and a preparation method thereof. The ictalurus punctatus fry starter feed comprises 30-50 parts of fish meal, 5-15 parts of milk powder, 10-30 parts of fermented soybean meal, 15-19 parts of flour, 5-15 parts of soybean protein concentrate, 1-3 parts of yeast hydrolysate and 1-3 parts of premix. The milk powder is added into the ictalurus punctatus fry starter feed to promote the intestinal development of the fries and improve the protein digestibility and immune globulin; the yeast hydrolysate promotes intestinal development ofthe ictalurus punctatus fries, and meanwhile, the digestion and absorption rate of food in the intestinal tract is increased; and preparation process parameters are optimized to obtain the special starter feed for ictalurus punctatus. According to the special starter feed for the ictalurus punctatus fries obtained by the technical scheme provided by the invention, in the same culture period, the weight reaches 100-150g, the survival rate reaches 86-93%, the growth speed is 1.02-1.26, and data support is provided for development of the starter feed for the ictalurus punctatus fries in 3-20 daysafter the ictalurus punctatus fries are put into a pond.
Description
technical field [0001] The invention relates to the technical field of feed, in particular to an open feed for channel catfish fry, a preparation method and the technical field of application thereof. Background technique [0002] Channel catfish (Ictalurus punctatus), also known as American catfish and channel catfish, belongs to Siluriformes [Siluriformes] and Cataluridae [Ictaluridae]. It is native to North America and belongs to a large freshwater fish of Siluriformes. Introduced in 1984. The meat content of this fish is 75.71%, the crude protein in the muscle accounts for 19.42%, and the fat accounts for 1.01%. It has the advantages of strong disease resistance and high catch rate. It is an excellent freshwater aquaculture variety with high nutritional value and economic value, and is favored by consumers and farmers. After several years of research and promotion of breeding, this fish is currently suitable for breeding in most areas of China. [0003] In the norther...
