Embodiment 1

[0035] A nutritional formula for resisting gossypol-induced fish enteritis, comprising 0.0081 parts of iron, 1.8 parts of valine, and 0.0007 parts of riboflavin in parts by weight, which are mixed to prepare the nutritional formula S1.

[0036] In order to facilitate the description of the application effect of S1 in this example, a fish enteritis model was established according to the method described in the application number CN2016102763590, and 192 mid-growth grass carp 220-232 g were used as objects for establishing the enteritis model, and they were randomly divided into two treatment groups. There were 3 replicates in each group, 32 fish in each replicate, and there was no significant difference in initial body weight between groups. The diet of the test group was fish feed containing a prescribed ratio of nutritional formula, and the diet of the control group was fish feed of the same weight without adding the nutritional formula. The basal feed ingredients were the sa...

Embodiment 2

[0041] In terms of parts by weight, 0.0053 parts of iron, 2.1 parts of valine, and 0.0005 parts of riboflavin were mixed to prepare nutritional composition S2.

[0042] The remaining operating methods are the same as in Example 1, and the test data of the fish intestine, spleen and head kidney immunity and pathogen resistance are recorded in Table 1.

Embodiment 3

[0044] Take 0.013 parts of iron, 1.4 parts of valine, and 0.0009 parts of riboflavin, and mix them to prepare nutritional formula S3.

[0045] The remaining operating methods are the same as in Example 1, and the test data of the fish intestine, spleen and head kidney immunity and pathogen resistance are recorded in Table 1.

Abstract

The invention discloses a nutrition formula for resisting gossypol-induced fish enteritis, a use method, application and a feed. The nutrition formula for resisting gossypol-induced fish enteritis comprises the following ingredients (by weight): 0.0053-0.013 part of iron, 1.4-2.1 parts of valine and 0.0005-0.0009 part of riboflavin. A fish feed is prepared from the nutritional formula composed of the above ingredients according to the above ratio. When the fish feed is applied to cultured freshwater fishes, gossypol-induced fish enteritis can be effectively prevented, and vacuolation of intestine epithelia, exfoliation of epithelial cells at two sides of plica and flattening of plica top are reduced.

Description

technical field [0001] The invention relates to the technical field of animal health breeding, in particular to a nutritional formula, use method, application and feed for resisting gossypol-induced fish enteritis. Background technique [0002] With the development of aquaculture and feed industry, the shortage of feed protein resources has become a common problem in the world, and it has become one of the serious restrictive factors for the development of aquaculture industry. Cotton is one of the most important crops in the world, with large output and low production cost, which makes the price of cotton products relatively low. my country ranks first among the countries with the highest cotton production. With the continuous improvement of cotton planting technology, the production has developed greatly, the yield per mu has continued to increase, and its planting range has continued to expand. It is expected that my country's cotton production will continue to increase....
