Embodiment 1

[0019] A feed additive for improving vaccine antibody titer, consisting of the following components in parts by weight;

[0020] Threonine: 25kg; Tryptophan: 25kg; Biotin: 0.0001kg; Vitamin C: 1kg; Glucose: 10kg; Glutamine: 5kg; Sodium Bicarbonate: 1kg; Potassium Bicarbonate: 1kg; Salt: 1kg.

[0021] By adding the product of the invention (10g of this product per pig per day) to drinking water 5-7 days before and after piglets were injected with circovirus, the antibody titers of 7d, 14d, 21d, 28d, and 35d after the injection were detected, and the antibody titers were found. The price was significantly higher than that of the group inoculated without drinking water and fed this product, which greatly improved the protective effect of the vaccine.

[0022] This invention of table 1 improves the effect table of piglet circovirus vaccine antibody titer (the data of 4 breeding farms, 80 heads of control group, 1083 heads of inoculation group, inoculation+drinking 1100 heads of pr...

Embodiment 2

[0025] A feed additive for improving vaccine antibody titer, characterized in that it consists of the following components in parts by weight;

[0026] Threonine: 30kg; Tryptophan: 30kg; Biotin: 0.1kg; Vitamin C: 5kg; Glucose: 30kg; Glutamine: 10kg; Sodium bicarbonate: 5kg; Potassium bicarbonate: 5kg; Salt: 3kg.

[0027] Add the product of the invention (10-15g of this product per pig per day) to drinking water 5-7 days before and after injection of reproductive and respiratory syndrome in growing and finishing pigs, and detect the antibody effect of 7d, 14d, 21d, 28d, 35d after the injection of the vaccine It was found that the antibody titer was significantly higher than that of the group inoculated without drinking water and fed this product, which greatly improved the protective effect of the vaccine.

[0028] Table 2 The effect of the invention on improving the titer of reproductive and respiratory syndrome antibodies in growing and finishing pigs (data from 5 farms, 90 h...

Embodiment 3

[0031] A feed additive for improving vaccine antibody titer, characterized in that it consists of the following components in parts by weight;

[0032] Threonine: 22kg; Tryptophan: 23kg; Biotin: 0.001kg; Vitamin C: 2kg; Glucose: 15kg; Glutamine: 8kg; Sodium bicarbonate: 2kg; Potassium bicarbonate: 3kg; Salt: 2kg.

[0033] By adding the product of the invention (10-15g of this product per pig per day) to drinking water 5-7 days before and after pregnancy sows were inoculated with pseudorabies, the antibody titer was detected 9 days after injection and during delivery, and the antibody titer was found to be extremely high. Significantly higher than that of the group inoculated without drinking water and fed this product, which greatly improved the protective effect of the vaccine.

[0034] This invention of table 3 improves the effect table (data of 8 breeding farms, 50 heads of control group, 800 heads of inoculation group, 800 heads of inoculation+this product group) of raisin...

Abstract

The invention discloses a feed additive for enhancing the valence of a vaccine antibody. The feed additive is characterized by comprising the following components according to parts by weight: 25 to 30 parts of threonine, 25 to 30 parts of tryptophan, 0.0001 to 0.1 part of biotin, 1 to 5 parts of vitamin C, 10 to 30 parts of glucose, 5 to 10 parts of glutamine, 1 to 5 parts of sodium bicarbonate, 1 to 5 parts of potassium bicarbonate and 1 to 3 parts of salt. The feed additive can relieve the oxidation injury of mycotoxin to the epithelia of the intestinal tract by protecting the integrality and function of the epithelia of the intestinal tract of a pig, relieves the harm of the mycotoxin by enhancing the oxidation resistance and the immunological function of a pig organism, and keeps the production performance of the pig.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving vaccine antibody titer. Background technique [0002] In recent years, porcine severe infectious diseases or highly variable infectious diseases have occurred frequently, seriously threatening the health and safety of pig populations, and resulting in significant economic losses. At present, the prevention and treatment methods for porcine infectious diseases are mainly based on prevention, that is, vaccination. However, negative effects such as immune stress, antibody-dependent enhancement, toxicological reversion, and decreased immunity caused by vaccination lead to immune failure and production performance decline. Because animal nutritional status affects the body's immune function and resistance to disease, the health of the body also affects the animal's nutritional demand pattern. Contents of the invention [0003] In order to solve the above problems, t...
