specific Embodiment approach 1

[0009] Specific embodiment one: this embodiment is a kind of feed additive that improves the protein utilization rate of sturgeon feed by weight parts by 30~40 parts of α-ketoglutaric acid, 25 parts~35 parts of arginine, 3.0 parts~ 4.5 parts of N-carbamoylglutamic acid and 20 to 35 parts of cellulose are mixed.

[0010] The beneficial effects of this embodiment are: a feed additive for improving the protein utilization rate of sturgeon feed of the present invention uses α-ketoglutaric acid and N-carbamylglutamic acid to jointly promote nitrogen deposition in the body, and at the same time combines functional Amino acid-arginine improves the protein utilization rate of sturgeon feed, and the protein efficiency can be increased by about 33%, which promotes growth and reduces the feed coefficient, which is only 0.7.

[0011] In this embodiment, α-ketoglutarate (AKG) is an intermediate product of the tricarboxylic acid cycle in the body, and NH + 4 Glutamate is produced by trans...

specific Embodiment approach 2

[0015] Specific embodiment two: The difference between this embodiment and specific embodiment one is: the feed additive for improving the protein utilization rate of sturgeon feed consists of 33.3 parts of α-ketoglutarate and 33.3 parts of arginine in parts by weight. , 3.4 parts of N-carbamoylglutamic acid and 30.0 parts of cellulose are mixed. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0016] Specific embodiment three: a kind of adding method of the feed additive that improves the protein utilization rate of sturgeon feed described in this embodiment is specifically carried out according to the following steps:

[0017] Take by weight 2-4 parts of feed additives and 96 parts-98 parts of sturgeon feeds that improve the protein utilization rate of sturgeon feed, and then combine the feed additives that have been weighed to improve the protein utilization rate of sturgeon feeds with the sturgeon feed Mixing means the addition of a feed additive that improves the protein utilization of sturgeon feed.

Abstract

The invention relates to a feed additive and an addition method thereof, in particular to a feed additive for increasing a protein utilization rate of sturgeon feed and an addition method of the feed additive. The additive aims at solving the problems of low protein utilization rate, low conversion rate, poor use effect and high feed coefficient of the existing sturgeon feed. The feed additive is prepared by mixing alpha-ketoglutarate, arginine, N-carbamylglutamate and cellulose. The addition method comprises the step of mixing 2-4 parts of feed additive for increasing the protein utilization rate of the sturgeon feed with 96-98 parts of sturgeon feed. The invention provides a feed additive for increasing the protein utilization rate of the sturgeon feed and the addition method of the feed additive.

Description

technical field [0001] The present invention relates to a feed additive and its adding method. Background technique [0002] The utilization rate of protein in sturgeon feed is generally less than 40%, the feed conversion rate is low, and the use effect is not good, that is, the feed coefficient is high, which can reach about 1.5, and the undigested nitrogen is mainly feces, urea nitrogen and excreted in the form of ammonia nitrogen. The discharge of ammonia nitrogen from the body is not only a waste of protein resources, but also causes serious pollution to the aquaculture water and affects the growth and immune function of fish. Contents of the invention [0003] The invention aims to solve the problems of low protein utilization rate, low conversion rate, poor use effect and high feed coefficient in existing sturgeon feed, and provides a feed additive and its adding method for improving the protein utilization rate of sturgeon feed . [0004] A feed additive for impr...
