Problems solved by technology

[0004] As an essential trace element for animals, inorganic sodium selenite is mostly used as an animal feed additive at present. Animals must pass through various biological barriers to absorb and utilize this inorganic salt. The absorption rate is low, the addition amount is large, and the biological potency is low. Most of them also pollute the environment after being excreted by feces, and have a destructive effect on the activity of other nutrients (such as vitamins, etc.) in the feed.
There are also situations where solid cysteine ​​and inorganic selenium are used together as feed additives, but the operation process is complicated, the dissolution of solid cysteine ​​is also difficult, and inorganic selenium is highly toxic, and has been banned or restricted by many countries.

Embodiment 1

[0018] Example 1: Application of selenocysteine ​​in chicken feed.

[0019] Application of selenocysteine ​​in chicken feed additive. Selenocysteine ​​was used in the feeding experiment of laying hens, and the selenocysteine ​​feed additive was added to the feed of laying hens in solid form. 28-week-old commercial generation green-shell layer hens with strong physique, similar body weight and similar laying performance were randomly divided into 3 groups, 20 birds in each group, and the test period was 28 days. During the experiment, free access to food and water, daily observation of the health status of chickens, record the number of eggs, egg weight and feed consumption in each group. Among them, 20 g of sodium selenite was added per ton of rations in the control group, 0.1 g of selenocysteine ​​was added per ton of basal rations in the test group, and selenocysteine ​​was added per ton of basal rations in the test group 2 20g, the test results are shown in Table 1 below....

Embodiment 2

[0024] Example 2: Application of Selenocysteine ​​in Weaned Piglets

[0025] Application of selenocysteine ​​in pig feed additive. Selenocysteine ​​was used in a feeding trial of weaned piglets, and the selenocysteine ​​feed additive was added to the feed of weaned piglets in solid form. A total of 108 healthy disease-free weaned piglets of the same breed (Du × Chang × Da) and similar in birth age were selected and randomly divided into a control group and two experimental groups, with 6 replicates in each group and 6 pigs in each replicate. Among them, 20g of sodium selenite was added to the basal ration of pigs per ton in the control group, 0.1g of selenocysteine ​​was added to the basal ration of pigs in the test group, and 0.1g of selenocysteine ​​was added to the basal ration of pigs in the test group. 20g of selenocysteine ​​was added to it. The feeding time is 2 weeks, and the feeding effect is shown in Table 2 below:

Embodiment 3

[0030] Example 3: Application of Selenocysteine ​​in Growing Pigs

[0031] Application of selenocysteine ​​in pig feed additive. Selenocysteine ​​was used in feeding trials with growing pigs, and the selenocysteine ​​feed additive was added to the feed of growing pigs in solid form. From 12 litters of "Du Dachang" three-way hybrid growing pigs, 80 healthy pigs were selected as experimental pigs, and randomly divided into 4 groups according to body weight and sex, 20 pigs in each group, and numbered. Group I (control group) is the basal ration for pigs, Add sodium selenite 2g in the basal ration for every ton of pigs in II group, add 2g of selenocysteine ​​in the basal ration for pigs in III group, IV Add 5g of selenocysteine ​​to the basal diet for each ton of pigs in the group. The test period is 14 days. The experimental pigs were fed in groups with free access to food and water. After 14 days, the indexes of ALB, TP, GLOB, CHL, BUN, Ca and P in serum of growing pigs wer...

Abstract

The invention discloses an application of selenocysteine in an animal feed additive. The animal feed additive is particularly a feed additive for pigs, birds, ruminants, aquatic animals, special economic animals or pets. The application of selenocysteine in animal feed additive has the advantages of safety, high efficiency, no toxicity, environment friendliness, capability of remarkably promoting synchronous absorption of animals on cysteine and selenium serving as a trace element and the like.

Description

technical field [0001] The invention relates to a specific application of amino acid, in particular to a specific application of selenocysteine ​​in the field of feed. Background technique [0002] Cysteine ​​is an amino acid with physiological functions and has been widely used in food additives. Cysteine ​​has many physiological functions: (1) It has chelating effect in organisms, so it is effective against a wide range of poisons such as formaldehyde, acetaldehyde, chloroform, carbon tetrachloride, lead, cadmium, methylmercury chloride, peroxide, etc. Fat oxide, PCB, tetrodotoxin, alcohol, etc. have effective detoxification effects, which have been proved by experiments; (2) maintain the normal metabolism of the skin, make the animal skin red and shiny, and can also be used to treat a wide range of skin diseases; ( 3) It can prolong the breeding period; (4) It can strengthen the defense ability of the animal body itself and adjust the defense mechanism of the organism. ...
