Embodiment 1

[0025] Take 0.41 parts by weight of tryptophan, 0.00013 parts by weight of thiamine, and 0.0053 parts by weight of iron, and mix them to prepare nutritional formula S1.

[0026] In order to verify the application effect of the present invention, the nutritional formula of the present invention was tested on grass carp (body weight 295-300g) in 12 farms in Sichuan, Chongqing and Guangxi. The test fish were equally divided into two groups, the test group and the control group, and each treatment group was set up with 3 replicates, with 4000 fish per replicate, and there was no significant difference in the initial body weight between the groups. The diet of the test group was fish feed added with the above nutritional formula S1 according to 0.4wt% of the total weight of the fish feed; the diet of the control group was fish feed of the same weight without adding the nutritional formula S1. The fish in the two treatment groups were fed 4 times a day, and the amount of each feedin...

Embodiment 2

[0029] Take 0.61 parts by weight of tryptophan, 0.0002 parts by weight of thiamine, and 0.0098 parts by weight of iron, and mix them to prepare nutritional formula S2.

Embodiment 3

[0031] Take 0.17 parts by weight of tryptophan, 0.000004 parts by weight of thiamine, and 0.0038 parts by weight of iron, and mix them to prepare nutritional formula S3.

Abstract

The invention discloses a nutritional composition for preventing fish gill hyperemia and rotted gill diseases caused by ammonia nitrogen in water and a feed. The nutritional composition comprises the following components in parts by weight: 0.17-0.61 part of tryptophan, 0.000004-0.0002 part of thiamine and 0.0038-0.0098 part of iron. Due to the addition of the nutritional composition for fishes within the range, fish gill hyperemia and rotted gill diseases caused by ammonia nitrogen in water can be effectively prevented, the occurrence rate of fish gill hyperemia and rotted gill diseases can be reduced, and gills and fishes can be kept healthy. Meanwhile, the growth of the fishes can be promoted, and the efficiency of the feed can be increased. The nutritional composition has the advantages of convenience in use, low cost and the like.

Description

technical field [0001] The invention belongs to the field of fish farming, and in particular relates to a nutritional formula for preventing gill congestion and gill rot of fish caused by ammonia nitrogen in water and a feed containing the formula. Background technique [0002] Fish meat is rich in high-quality protein, a variety of mineral elements and vitamins. It is one of the important meat products for improving dietary structure and improving human health. The per capita consumption in my country accounts for nearly 1 / 3 of the total meat, and the annual per capita consumption reaches nearly 40kg. The rapid growth of consumer demand has driven the rapid development of the fish farming industry. The output of high-density intensive aquaculture accounts for 60% of the total aquatic products in my country, which has become the theme of my country's aquatic product supply, and its proportion is steadily increasing. However, high-density intensive aquaculture has greatly inc...
