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 formula and feed for preventing fish gill congestion and gill rot caused by ammonia nitrogen in water. The nutritional formula includes the following components in parts by weight: 0.17-0.61 part of tryptophan, 0.000004-0.0002 part of thiamine parts, iron 0.0038‑0.0098 parts. The present invention can effectively prevent gill congestion and gill rot caused by ammonia nitrogen in water by adding the above-mentioned range of fish nutrition formula, reduce the incidence of gill congestion and gill rot, and ensure the health of gills and fish. At the same time, it can promote fish growth and improve feed efficiency. The utility model has the advantages of convenient use and low cost.

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...
