Embodiment 1

[0015] Embodiment 1. Get 30 kilograms of fish meal, 15 kilograms of soybean meal, 14 kilograms of soybean protein powder, 25 kilograms of flour and mix to form the base material mixture, then get 600 grams of soybean oligosaccharides, 600 grams of inulin, 200 grams of galactooligosaccharides, low Mix 600 grams of polyfructose to form a probiotic-promoting substance mixture, sprinkle the probiotic-promoting substance mixture evenly on the base material mixture, stir well, then add an appropriate amount of water to form a batter, extrude and granulate on a granulator to form a diameter About 3 mm long particles with a length of about 1-2 cm, dried.

Embodiment 2

[0016] Embodiment 2. For the shrimp ponds that have been put in a suitable place for half a month to one month, when feeding feed such as screw meat, red worm, feed the compound feed of the present invention at an amount of about 500 grams per mu of water surface every day, divided into Three times in the morning, middle and evening, and compound fertilizer with trace elements every day.

Abstract

The invention provides a compound feed for giant freshwater prawns. The compound feed is prepared from the following components in parts by weight: 27-33 parts of fish meal, 12-18 parts of bean pulp, 10-18 parts of soybean protein powder and 20-25 parts of flour; the compound feed is characterized by further comprising 0.5-3 parts of probiotic promoting substance. After the prawns eat the compound feed, the probiotic promoting substance is capable of promoting the growth of the effective microbial community in the bodies of the prawns so that the prawns can be healthier, grow vigorously, and be stronger. Excess feed thrown in the vigorous growth period of the prawns is dissolved into water and then the probiotic promoting substance in the feed is released into the water to promote the growth of the effective microbial community in the water body, and therefore, the water quality can be improved, the problem of eutrophication caused by the excess feed is solved and a good beneficial cycle is formed.

Description

technical field [0001] The invention belongs to the technical field of macrobrachium rosenbergii culture, and in particular relates to a macrobrachium rosenbergii compound feed. Background technique [0002] Giant giant rosenbergii (Macrobrachium rosenbergii) is native to the Indo-Pacific region and lives in various types of freshwater or brackish water. Since the 1960s, it has been transplanted to some countries and regions in Asia, Europe, and America. One of the most abundant shrimps. [0003] Macrobrachium rosenbergii is omnivorous, zooplankton, aquatic insects, aquatic plants, algae; cakes, rice bran, bran, etc. can be ingested, generally fed with artificial pellet feed. Macrobrachium rosenbergii has higher requirements on water quality, but when the shrimp grows vigorously, they will be fed with more feed, which often produces excess feed, which makes the water body eutrophic. Contents of the invention [0004] In order to solve the problem of water eutrophication ...
