Problems solved by technology

However, there is no special compound feed for C. bidentatum at present, and there is no literature report on its nutritional requirements. Farmers generally use shrimp compound feed to carry out their farming, which restricts the artificial breeding industry of C. bidentatum to a large extent. healthy development of

Embodiment 1

[0013] Prepare 100kg of compound feed and its raw material composition is as follows: 8kg of fish meal, 22kg of fermented soybean meal, 20kg of fermented rapeseed meal, 10 kg of peanut meal, 5 kg of cotton meal, 5 kg of DDGS (distiller’s grain protein and its soluble matter), 25 kg of wheat, Mixed oil 5 kg.

[0014] The total protein content of the compound feed is about 34%, and the total fat content is about 7%. Using this feed and two control feeds (currently commonly used feeds for P. didentensis cultured, respectively, a certain brand of Chinese shrimp feed and a certain brand of Penaeus vannamei feed, the total protein content is about 38% and 32% respectively) under the same conditions Feeding young clamworms with an average initial body weight of 8.56 mg / carp, sampling and analysis after 70 days of feeding, the weight gain rate of the feed of the present invention was increased by 13.93% and 19.61%, respectively, and the feed coefficient was reduced by 9.55% and 15.87%...

Embodiment 2

[0016] Prepare 100kg of compound feed and its raw material composition is: 5kg of fish meal, 25kg of fermented soybean meal, 20kg of fermented rapeseed meal, 6 kg of peanut meal, 5 kg of cotton meal, 4 kg of DDGS (distiller’s grain protein and its soluble matter), 28 kg of wheat, Mixed oil 7 kg.

[0017] The total protein content of the compound feed is about 31%, and the total fat content is about 9%. Using this feed and two control feeds (currently commonly used feeds for P. didentensis cultured, respectively, a certain brand of Chinese shrimp feed and a certain brand of Penaeus vannamei feed, the total protein content is about 38% and 32% respectively) under the same conditions Feeding young clamworms with an average initial body weight of 8.56 mg / carp, sampling and analysis after 70 days of feeding, the weight gain rate of the feed of the present invention increased by 18.76% and 26.29%, respectively, and the feed coefficient decreased by 11.19% and 16.87% compared with th...

Embodiment 3

[0019] Prepare 100kg of compound feed and its raw materials are as follows: 5kg of fish meal, 20kg of fermented soybean meal, 15kg of fermented rapeseed meal, 5kg of peanut meal, 5kg of cotton meal, 4 kg of DDGS (distiller’s grain protein and its soluble matter) , 37 kg of wheat, mixed Oil 9 kg.

[0020] The total protein content of the compound feed is about 28%, and the total fat content is about 11%. Using this feed and two control feeds (currently commonly used feeds for P. didentensis cultured, respectively, a certain brand of Chinese shrimp feed and a certain brand of Penaeus vannamei feed, the total protein content is about 38% and 32% respectively) under the same conditions Feeding young clamworms with an average initial body weight of 8.56 mg / carp, sampling and analysis after 70 days of feeding, the weight gain rate of the feed of the present invention was respectively increased by 5.38% and 11.67% compared with the two control feeds, and the feed coefficient was resp...

Abstract

The invention relates to an environment-friendly compound feed for clam worms, characterized in that the total protein content of the feed is 28-34%, and the total fat content is 7-11%; the components and the mass of each component are 100% The content is: fish meal 5‑10%, fermented soybean meal 20‑25%, fermented rapeseed meal 15‑20%, peanut meal 5‑10%, cotton meal 5‑10%, DDGS (corn distiller's grain protein and its solubles) 4‑8%, wheat 25‑40%, mixed oil (cotton oil: vegetable oil: soybean oil = 3:2:1) 5‑9%. The double-toothed clamworm compound feed of the present invention has a fermented fragrance type, is rich in cell protein, various digestive enzymes and growth-promoting factors, and has comprehensive and balanced nutrition, strong food-attraction, good growth-promoting effect, high conversion utilization rate, and low cost , Efficient and environmentally friendly.

Description

technical field [0001] The invention relates to a high-efficiency and environment-friendly compound feed for clam worm with double teeth, belonging to the technical field of aquatic feed. Background technique [0002] Double-toothed clamworm ( Perinereis aibuhitensis ) belongs to Nereididae (Nereididae) in zoological classification, and Perinereis (Perinereis), commonly known as sea centipede, sea leech, etc., is mainly distributed in my country. It is relatively fast and has the largest amount of biological resources. It is distributed in middle and high tide beaches from south to north in my country's coastal areas. It is the main representative and dominant species of polychaete ecological types in the intertidal zone, and it is also the most important source of artificial breeding and export earnings in my country. type. Because it is widely used in aquaculture, fishing and medical care, etc., the demand in domestic and foreign markets is very large, and there are often ...
