Cynoglossus semilaevis larva pellet feed and preparation method

Abstract

The invention discloses cynoglossus semilaevis larva pellet feed which comprises components in parts by weight as follows: animal nutrients, plant nutrients, Chinese herbal medicine, vitamins, trace elements, lentinan, laminarin, nitrifying bacteria, marine yeast, photosynthetic bacteria, glucan, methionine and L-lysine. The preparation method of the cynoglossus semilaevis larva pellet feed comprises the following steps: (1), preparing the raw materials; (2), synthesizing a biological material; (3), converting the biological material into a mature material; (4), performing bulking granulation; (5), performing drying, (6), performing spray film coating; and (7), performing vacuum drying. The cynoglossus semilaevis larva pellet feed and the preparation method have the advantages as follows: the survival rate, the growing speed and the feed conversion efficiency of cynoglossus semilaevis larvae can be increased, the disease resistance of the cynoglossus semilaevis larvae can be improved, and the feed cost in a cultivation process can be reduced.

Description

Technical field [0001] The present invention involves the field of feed processing technology, and it specifically involves a semi -slip tongue -tongue purse fish granules and preparation methods. Background technique [0002] Half -slip tongue is a category of pimple breeding that my country has developed in recent years.As a precious variety in seafood fish, due to delicious taste, rich in unsaturated fatty acids, tender muscles, smooth taste, high vitamin content, and is loved by consumers.However, due to the large differences in the male and female individuals of the semi -sliding tongue, the number of male fish is small and the individual is small, the reproductive ability is weak, resulting in weak reproductive ability of wild populations, and there are fewer individuals in the natural world. [0003] Semi -slip tongue is a bottom -lived fish, with a wide range of food and low food level.The half -slip tongue is eaten in a swallowing manner. It cannot bite large foods. It c...

Problems solved by technology

[0004] In the current breeding process of tongue sole juveniles, general-purpose seawater fish feeds are generally used for breeding, and the unique feeding and nutritional characteristics of tongue sole are not considered, resulting in that the feed cannot effectively meet the physiology and nutrition of tongue sole juveniles demand, not only caused the waste of feed materials, but also made the breeding cycle of tongue sole longer, and the breeding efficiency was low
