Problems solved by technology

[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.

Embodiment

[0014] A preparation method of a feed premix for Penaeus vannamei breeding to attract and digest food, comprising the following steps:

[0015] (1) Selection of raw materials: cod liver oil, hawthorn fruit, Luo Han Guo, raw oyster meat, raw squid meat;

[0016] (2) Cleaning of raw materials: Wash hawthorn fruit, Luo Han Guo, raw oyster meat and raw squid meat with clean water to remove impurities and drain excess water;

[0017] (3) Mixing and drying: put hawthorn fruit, mangosteen fruit, raw oyster meat, and raw squid meat into the mixer and stir for 20 minutes to make them fully mixed, and dry them with an electrostatic field dryer at room temperature at 25°C-35°C until the moisture content is ≤3% ;

[0018] (4) Grinding: put the dried mixture into a feed grinder and grind it to a fineness of 60 mesh;

[0019] (5) Encapsulation: add the pulverized mixture into cod liver oil and mix evenly with a mixer, then seal it in a can.

[0020] Further, a method for using a feed pre...

Abstract

The invention discloses preparation and application methods of a food-calling and digestion-helping feed pre-blending agent for culture of penaeus vannamei boone. The preparation method comprises the following steps: selecting raw materials, washing the raw materials, mixing and drying, crushing and packaging. The method has a simple flow, is convenient for processing and can be widely applied to industrial production; the prepared feed pre-blending agent contains rich animal proteins, and has unique fishy smells of cod-liver oil, fresh oyster meat, and fresh sleeve-fish meat and drug functions of hawthorn fruits; the feed pre-blending agent has food-calling and digestion-helping effects, can be used for effectively improving conditions of anorexia, inactive eating, low digestion capability and slow weight gain of the penaeus vannamei boone, a digestion capability and an active eating capability of the penaeus vannamei boone are promoted, and stable growth of the penaeus vannamei boone is accelerated.

Description

technical field [0001] The invention relates to the technical field of marine product cultivation, in particular to a method for preparing and using 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 ve...
