Embodiment 1

[0034]Mix 30 parts of fish meal, 10 parts of animal feed (including 6 parts of meat and bone meal, 1 part of shrimp head powder, and 3 parts of squid paste), 50 parts of vegetable feed (including 14 parts of flour, 21 parts of soybean meal, 10 parts of rapeseed meal, peanut 5 parts of meal), 5 parts of oil, 1 part of multivitamin, 2 parts of compound mineral, 0.5 part of bile acid, 0.5 part of taurine, 1 part of other ingredients (including 0.2 part of shelling factor, 0.3 part of binder, digestion 0.5 part of enzyme), stirring and mixing, and obtaining the feed for preventing white stool of prawns after pelleting.

[0035] Taking Penaeus vannamei as a test example, use the above-mentioned feed for 1-2 days every 7-10 days, or feed this feed every other week, and the amount of feeding should be full; during the prevention period, artificial oxygenation should be strengthened to ensure that the bottom of the pond is full throughout the day. (including at night) dissolved oxygen...

Embodiment 2

[0038] Mix 35 parts of fish meal, 15 parts of animal feed (including 10 parts of meat and bone meal, 2 parts of shrimp head powder, 3 parts of squid paste), 40 parts of vegetable feed (including 14 parts of flour, 16 parts of soybean meal, 6 parts of rapeseed meal, peanut 4 parts of meal), 5 parts of oil, 1 part of multivitamin, 2 parts of compound mineral, 0.5 part of bile acid, 0.5 part of taurine, 1 part of other ingredients (including 0.2 part of shelling factor, 0.3 part of binder, digestion Enzyme 0.5) Stir and mix evenly, and obtain feed for preventing and treating white stools of prawns after granulating.

[0039] Taking the early stage of "white stool" of Penaeus vannamei as a test case, use it continuously for more than 1 week or until it is cured, and the feeding amount should be full; during the treatment period, artificial oxygenation should be strengthened to ensure dissolved oxygen at the bottom of the pond throughout the day (including night) Above 4.5mg / L.

Embodiment 3

[0042] 40 parts of fish meal, 20 parts of animal feed (including 14 parts of meat and bone meal, 3 parts of shrimp head powder, 3 parts of squid paste), 25 parts of vegetable feed (including 12 parts of tapioca starch, 8 parts of soybean meal, and 5 parts of rapeseed meal) , 10 parts of oil, 1 part of multivitamin, 2 parts of compound mineral, 0.5 part of bile acid, 0.5 part of taurine, 1 part of other ingredients (including 0.2 part of shelling factor, 0.3 part of adhesive, 0.5 part of digestive enzyme) and stir After mixing and granulating, the feed for treating white stools of prawns is obtained.

[0043] Taking Penaeus vannamei with serious "white stool" as a test example, use it continuously for more than 1 week or until it is cured, and the feeding amount should be full; during the treatment period, artificial oxygenation should be strengthened to ensure that the bottom of the pond is whole day (including night) Dissolved oxygen is above 4.5mg / L.

Abstract

The invention discloses fodder for preventing and treating prawn clay-coledstool. The fodder is prepared from the following materials by weight: 30 to 40 parts of fish meal, 10 to 30 parts of animal feed except the fish meal, 25 to 50 parts of plant feed except bran, 4 to 10 parts of grease, 0.2 to 1 part of vitamin complex, 2 to 5 parts of compound mineral substance, 1 part of other additives of shelling element and the like, and 0.5 to 1 part of taurine or cholesterol or 0.2 to 0.8 part of bile acid or 0.5 to 1 part of mixture of the taurine, the cholesterol and the bile acid. According to the fodder disclosed by the invention, t the raw material proportion of the animal feed is increased, the raw material proportion of the plant feed is controlled, and especially the usage amount of a raw material containing rich soluble non-starch polysaccharides is controlled; the bile acid, the taurine and the cholesterol are supplemented, so that a signal channel for the liver to start synthesizing bile acid is inhibited, fat absorption is helped, and a good effect of preventing and treating prawn clay-coledstool is achieved.

Description

technical field [0001] The invention belongs to the field of shrimp feed, in particular to a feed for preventing and treating white stools of prawns.

The etiology of the disease is generally believed to have the following points: (1) seedling problems, the species of shrimp seedlings put in are not good, their physical fitness is poor, the structure and function of the hepatopancreas are not perfect, or ...
