Feed for young carps and preparation method of feed

Abstract

The invention discloses a feed for young carps and a preparation method of the feed. The feed for young carps comprises the following components in parts by weight: 15-20 parts of fish meal, 35-45 parts of hermetia illucens larvae, 18-25 parts of wheat bran, 10-15 parts of tomatoes, 18-25 parts of corn, 5-10 parts of hericium erinaceus, 8-15 parts of asparagus, 3-8 parts of garlic, 5-10 parts of black wood ears, 3-7 parts of complex vitamins, 5-10 parts of silkworm chrysalis, 3-8 parts of yeast, 15-25 parts of maifan stones, 1-5 parts of heartleaf houttuynia herbs and 0.5-1.5 parts of minerals. The preparation method comprises the following steps of (1) preparing hermetia illucens larva powder and silkworm chrysalis meal; (2) crushing the tomatoes, the corn, the hericium erinaceus, the asparagus, the garlic, the black wood ears and the heartleaf houttuynia herbs, and then performing fermentation to prepare fermented slurry; (3) performing mixed granulation on the hermetia illucens larva powder, the silkworm chrysalis meal, the fermented slurry, the fish meal, the maifan stones and the minerals; and (4) performing sterilization and performing packing. The feed can improve the immunity of the young carps.

Description

Technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a carp feed and a preparation method thereof. Background technique [0002] Common carp, also known as Cyprinus carpio, belongs to Cypriniformes and Cyprinidae. It is a benthic omnivorous fish that eats both meat and vegetables. It has a wide range of bait, well-developed rostral, and often eats in mud. It is a traditional fine variety of freshwater aquaculture in my country and has rich practical and nutritional value. [0003] The existing carp feed is generally formulated with bran, bean cake, barley, fish meal, and added with multivitamins, inorganic salts, lysine, and methionine to meet the needs of carp's protein, fatty acid and other nutrients in the production process. [0004] However, there is a lack of research on the feed of carp juveniles. Because the physiology and immune system of carp juveniles are not fully developed, it is easy to make carp juveniles get sick witho...

Problems solved by technology

[0005] The present invention aims at the above-mentioned problem that the juvenile carp's physiology and immune system are not fully developed and easily causes the juvenile carp to be infected with disease, and provides a feed for juvenile carp and a preparation method thereof. The feed can enhance the lymphatic T of juvenile carp. Cells, phagocytes and immunoglobulins, and can inhibit antibacterial, thereby improving the immunity of carp juveniles, thereby reducing the disease rate of carp juveniles
