Problems solved by technology

After reviewing a large number of documents, it is known that the protein requirement of juvenile crayfish is about 29%. Feeds with high protein content not only cause waste of protein resources, but also increase the ammonia nitrogen content of the water body and increase the load of the water body

Embodiment １

[0020] Fish meal 29%, soybean meal 23%, flour 10%, bran 8%, corn meal 8%, mixed oil 2.4%, rice bran 13.6%, multivitamin 2%, complex minerals 3%, binder 0.5%, free 0.1% chitin, 0.4% salt.

[0021] The above-mentioned raw materials are crushed and mixed uniformly. The particle size is less than or equal to 1 mm. The uniformly mixed materials enter the modulator, tempered in steam at 95°C for 3 minutes, and extrude ￠1.5mm pellet feed through the pelletizer, and cool ,Bale.

[0022] The above feed formula is used in the early stage of crayfish juvenile cultivation.

[0023] The above feed formula was pelleted and fed to crayfish juveniles in the early stage, and the control group was fed with fresh fish and shrimps. The feeding period was 15 days. The survival rate of the control composition was 73% and the survival rate of the experiment composition was 71.8%, which was different from the control group. It is small, has a wide range of feed sources, is easy to store, and has obvious a...

Abstract

The invention discloses a pellet feed for young crayfish. The pellet feed is prepared from the following components by weight: 20%-32% of fish meal, 15%-30% of bean pulp, 8%-12% of flour, 6%-10% of bran, 6%-10% of corn flour, 0.5%-5.4% of mixed oil, 2%-30.8% of rice bran, 1%-2% of various vitamins, 2%-3% of composite mineral substance, 0.5% of adhesive, 0.05%-0.1% of exuviation element and 0.5%-1% of salt. The pellet feed for young crayfish contains 28%-32% of protein and achieves a good breeding effect as well; as the raw materials are cheap, therefore the breeding cost is effectively reduced, the breeding benefit of crayfish culturing farmers is increased; and protein resource waste is effectively reduced, ammonia content and nitrogen content in a water body are reduced, and the water load is decreased.

Description

technical field [0001] The invention relates to the field of feed, in particular to crayfish juvenile shrimp pellet feed and a production method thereof. Background technique [0002] At present, the crayfish market is good, and shrimp farmers are highly motivated to raise crayfish. However, there are few commercially available brands of crayfish juvenile feed, and the protein content is generally 43% to 46%. Therefore, the sales price is relatively high, and the shrimp The cost of farming is not conducive to the development of the artificially cultured crayfish industry in years when the market is not good. [0003] The high cost of crayfish juvenile shrimp pellet feed is mainly caused by the following two reasons: 1. High protein content, with a content of 43% to 46%; 2. High animal protein content in feed materials, of which animal protein is mainly fishmeal. After reviewing a large number of documents, it is known that the protein requirement of crayfish juveniles is a...
