example 1

[0015] After the feeding period, 14 piglets from the same sow were divided into 2 groups, and 7 piglets in each group were fed separately. The feed used was the same. Feed additives were added to the feed in the experimental group at a weight ratio of 1:100. , the additive is L-arginine-α-ketoglutarate (L-arginine and α-ketoglutarate are salted at a molar ratio of 1:1, also known as monoarginine ketoglutarate) , the control group was not added. After 12 months of breeding, the two groups were slaughtered and sold at the same time. As a result, the weight of the experimental group was 32% higher than that of the control group.

example 2

[0017] 40 Peking ducks were fed with the same feed, among which 20 were in the experimental group, the weight ratio in the feed was 1:200, and the molar ratio of L-arginine and α-ketoglutaric acid in the additive was salted at 2:1, and the control group Without additives, commercial ducks were bred for the same period of time and then slaughtered separately. The weight of the ducks in the experimental group was 25% higher than that in the control group.

Embodiment 3

[0019] In two fish ponds where the same species was raised, one was used as the experimental group, and feed additives were added to the feed at a weight ratio of 1:50, wherein L-arginine and α-ketoglutaric acid were salted at a molar ratio of 3:1 , and the other piece was used as a control group without additives. After feeding for 12 months, they were salvaged respectively, and 100 fish were randomly taken and weighed. The weight of the experimental group was 20% higher than that of the control group.

Abstract

The invention relates to a natural and safe growth-type feed additive which contains L-arginine-alpha-oxoglutarate, wherein the L-arginine and alpha-oxoglutarate are salified in the mole ratio of 1:2-5:1 and the weight ratio of the L-arginine-alpha-oxoglutarate added to the feed and the daily ration for animals to the feed and the daily ration for animals is 1:50-200. The weight ratio of the additive to the feed is 1:50-100 for livestock animals, 1:100-200 for poultry animals and 1:50-100 for aquatic animals.

Description

technical field [0001] The invention relates to a feed additive, in particular to a growth-promoting animal feed additive. Background technique [0002] L-Arginine-α-ketoglutarate, the English name is L-Arginine-alpha-Ketoglutarate, English abbreviation AAKG, it is different from the crystalline mixture of L-arginine and α-ketoglutarate, the common mixture is two There is no salt bond between them. L-arginine-α-ketoglutarate is white or light yellow crystal, easily soluble in water, HCl and NaOH solution, slightly soluble in ethanol, insoluble in acetone, ether, etc. [0003] L-arginine-α-ketoglutarate is an amino acid salt health product with increasing sales in the international market. As a functional nutritional enhancer and liver-protecting drug, it is mainly used Rapid muscle growth and recovery, promote the absorption of nutrients and energy by liver cells, and maintain normal liver function. Its main physiological mechanism is that L-arginine-α-ketoglutarate can p...
