Special feed for lobsters at post larval period

Abstract

The invention discloses a special feed for lobsters at a post larval period. The special feed is prepared from the following raw materials in parts by weight: 40-60 parts of corn, 5-15 parts of oat flour, 25-35 parts of millet, 5-10 parts of meat and bone meal, 2-8 parts of fermented sugarcane bagasse, 10-20 parts of fermented animal oil residues, 5-20 parts of crumbs, 5-10 parts of shrimp shell meal, 4-10 parts of sweet potato powder, 15-25 parts of rice bran, 1-2 parts of straw powder, 2-6 parts of watermelon peel, 1-5 parts of towel gourd stems, 2-6 parts of guar gum composite stone powder, 0.1-0.6 part of calcium hydrogen phosphate, 0.01-0.05 part of phytase, 2-5 parts of Chinese herbal medicines and 1-4 parts of a premix. The special feed disclosed by the invention is comprehensive and balanced in nutrients and rich in kinds of the raw materials, completely conforms to omnivorous characteristics of the lobsters at a post larval period, contains various good protein raw materials, and is also rich in trace elements, so that the food consumption of the lobsters at the post larval period is promoted, the growth and development speed of the lobsters at the post larval period is increased, the weight increment is obvious, the special feed conforms to digestive physiology of the lobsters at the post larval period, transition is easy to realize, and the survival rate is high.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed for lobster larvae. Background technique [0002] Crayfish are typical omnivores. It eats grass, aquatic plants, grain feed and animal feed. Feeding pure natural organic feeds such as artificially propagated aquatic organisms, small animals, and planted aquatic plants is better in palatability, rich in nutrition, fresh and delicious than purchased commercial feeds, and it is completely unnecessary to buy compound feeds. Lobster larvae are still in the growth and development stage. At present, the nutrients in ordinary feed are not easy to absorb, and the cost is high, which cannot meet the needs of lobster larvae. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a special feed for lobster larvae, which has comprehensive and balanced nutrition, rich types of raw materials, fully...
