Food calling and digestion helping feed pre-mixing agent formula for penaeus vannamei boone culture

Abstract

The invention discloses a food calling and digestion helping feed pre-mixing agent formula for penaeus vannamei boone culture and belongs to the technical field of sea food culture. A pre-mixing agent is prepared from, by weight, 40-50 parts of fish liver oil, 15-20 parts of dry hawthorn fruit powder, 5-10 parts of momordica grosvenori powder, 10-20 parts of fresh oyster powder and 10-20 parts of fresh squid powder. The pre-mixing agent suitable for being adopted by traditional cultivation feed can have the food calling and digestion helping functions by utilizing specific fishy smell of the fish liver oil, fresh oyster meat and fresh squid meat and efficacy of hawthorn fruits, and can effectively improve the conditions of anorexia, passive feeding, a low digestive ability and slow weight increase of prawns, the digestive ability and the active feeding ability of the prawns are promoted, and stable growth of the prawns is accelerated.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a formulation of a feed premix for the cultivation of Penaeus vannamei to attract and digest food. Background technique [0002] Penaeus vannamei has a thin shell and fat body, delicious meat, high meat content, and rich nutrition. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in southern my country. It is beneficial to sea people to increase their income, but the risk of breeding is also relatively high. This is because during the breeding process of prawns, they are easily affected by the factors of the breeding environment, feeding feed and feeding methods, and they are prone to not eating and growing slowly. Growth and weight growth are not obvious, and the current feed does not solve this problem well. Therefore, it is very urgent to dev...

[0002] Penaeus vannamei has a thin shell and fat body, delicious meat, high meat content, and rich nutrition. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in southern my country. It is beneficial to sea people to increase their income, but the risk of breeding is also relatively high. This is because during the breeding process of prawns, they are easily affected by the factors of the breeding environment, feeding feed and feeding methods, and they are prone to not eating and growing slowly. The growth of length and weight is not obvious, and the current feed does not solve this problem well. Therefore, it is very urgent to develop a feed premix that can promote active feeding of prawns and enhance their digestive function.
