Embodiment 1

[0027] Take 0.92 parts by weight of phenylalanine, 0.0034 parts by weight of niacin, 3.2 parts by weight of phospholipids, and 1.36 parts by weight of valine, and mix them to prepare the nutritional formula S1.

[0028] 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 250-260g) in 12 farms in Sichuan, Chongqing and Guangxi. The test fish were equally divided into two groups, the test group and the control group. Each treatment group had 3 replicates, and each replicate had 410 fish. There was no significant difference in the initial body weight between the groups. The diet of the test group was the fish feed added with the above nutritional formula S1 according to 5.2wt% of the total weight of the fish feed; the diet of the control group was the fish feed of the same weight without the nutritional formula S1. The fish in the two treatment groups were fed 4 times a day, and...

Embodiment 2

[0031] Take 1.68 parts by weight of phenylalanine, 0.0015 parts by weight of niacin, 1 part by weight of phospholipid, and 1.91 parts by weight of valine, and mix them to prepare the nutritional formula S2.

Embodiment 3

[0033] Take 0.61 parts by weight of phenylalanine, 0.0055 parts by weight of niacin, 5 parts by weight of phospholipids, and 0.88 parts by weight of valine, and mix them to prepare nutritional formula S3.

Abstract

The invention discloses a nutrition composition and a feed capable of enhancing ammonia-nitrogen stress resistance capability of a fish gill. The nutrition composition comprises the following components in parts by weight: 0.61-1.68 parts of phenylalanine, 0.0015-0.0055 part of nicotinic acid, 1-5 parts of phospholipid and 0.88-1.91 parts of valine. Through the addition of the nutrient composition within the range, congestion of the fish gill and rotted gill caused by ammonia and nitrogen rich in water can be effectively prevented; the gill congestion rate and the rotted gill rate are reduced; and the health of the gill and the organism is ensured.

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 rich in water and a feed containing the formula. Background technique [0002] Aquatic products have high protein content, low fat content, rich in minerals and vitamins, and are one of the important meat products to improve consumers' dietary structure and improve human health. With the strengthening of consumers' health awareness, the consumption of aquatic products in my country has increased sharply, and the per capita consumption has increased from 8kg in 2001 to nearly 40kg now. The rapidly increasing consumption can only be met by relying on high-density artificial breeding. At present, the consumption of artificially farmed fish products in my country exceeds 60% of the total consumption of fish products. However, while high-density artificial breeding has greatly ...
