Feed for feeding high-quality small white shrimps and preparation process thereof

Abstract

The invention discloses a feed for feeding high-quality small white shrimps and a preparation process of the feed. The preparation process includes: sequentially carrying out mixing, dedusting, deironing and sieving on 25-30 parts of soybean meal, 15-20 parts of rice meal, 25-30 parts of a fish meal protein material, 8-12 parts of algae powder, 4-6 parts of compound vitamin and 4-6 parts of a compound multi-mineral mixed material to obtain a mixture A, then putting the mixture A into a pulverizer to be pulverized twice to obtain a mixture B, then fully mixing the mixture B with 5-8 parts of wheat middling yeast, and performing secondary batching to obtain coarse feed, and finally, sequentially granulating, curing, cooling, crushing and grading the coarse feed, and packaging the finished product to obtain the finished feed. The method is a significant technical progress of an original breeding mode of the small white shrimps, and the obtained feed can provide basic nutrient substances for the small white shrimps in the growing period and promote rapid growth; after feeding, other protein supplements such as fresh trash fish do not need to be added, the technical effects of saving cost and purifying the water environment can be achieved, the growth effect of the small white shrimps is good, and the quality is obviously improved on year-on-year basis.

Description

technical field [0001] The invention relates to a shrimp feed, in particular to a feed for raising high-quality small white shrimps, and a preparation process of the feed. Background technique [0002] Carinicauda (E. carinicauda), also known as white rice shrimp and small white shrimp, belongs to the genus Exopalaemon in the family Palaemonidae of the order Decapoda. It is widely distributed in the coastal areas of my country, especially in the northern Jiangsu coast. The main species of mixed culture of shrimp, crab and shellfish. The body length of the ridgetail white shrimp is 4-9 cm, and there is an obvious longitudinal ridge in the center of the back of the abdomen from the 3rd to the 6th segment, hence the name. [0003] Small white shrimp generally live in the shallow sea or near the estuary of the sandy bottom, with a suitable salinity of 6.8-30.4, strong adaptability to the environment, fast growth and reproduction, and the output in the Yellow Sea and Bohai Sea is...

Problems solved by technology

[0004] Raising high-quality small white shrimp has high requirements on feed. In order to ensure the nutritional elements, protein supplements such as fresh miscellaneous fish need to be added during the breeding process. At present, these protein supplements are added extensively, and the cost of breeding is high, and it is easy to cause The water body is polluted, and it is impossible to maintain a good growth environment for small white shrimp
