Embodiment 1

[0023] Take 0.57 parts by weight of methionine hydroxyl analogs, 0.0135 parts by weight of vitamin C, and 0.054 parts by weight of vitamin A, and mix them to prepare fish feed additive S1.

[0024] In order to verify the application effect of the present invention, the fish feed additive of the present invention was tested on grass carp (body weight 258-260g) 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-mentioned feed additive S1 according to 0.6wt% of the total weight of the fish feed; the diet of the control group was fish feed of the same weight without adding the additive S1. The fish in the two treatment groups were fed 4 times a day, and the amount of...

Embodiment 2

[0027] Take 1.09 parts by weight of methionine hydroxyl analogs, 0.0225 parts by weight of vitamin C, and 0.018 parts by weight of vitamin A, and mix them to prepare fish feed additive S2.

Embodiment 3

[0029] Take 0.3 parts by weight of methionine hydroxyl analogue, 0.009 parts by weight of vitamin C, and 0.084 parts by weight of vitamin A, and mix them to prepare fish feed additive S3.

Abstract

The invention discloses a feed additive for preventing fish gill hyperemia and rotted gill diseases caused by ammonia nitrogen and a feed. The feed additive comprises the following components in parts by weight: 0.3-1.09 parts of methionine hydroxy analogue, 0.009-0.0225 part of vitamin C, and 0.018-0.084 part of vitamin A. Due to the addition of the feed additive 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 feed additive has the advantages of convenience in use, low cost and the like.

Description

technical field [0001] The invention belongs to the field of fish breeding, and in particular relates to a feed additive for preventing gill congestion and gill rot of fish caused by ammonia nitrogen in water and a feed containing the feed additive. 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 in...
