preparation example Construction

[0029] The invention provides a preparation method of an anti-heat stress feed additive, which comprises the following steps: mixing the feed additive described in the invention, and passing through a 30-60 mesh sieve to obtain the feed additive.

[0030] The present invention also provides an application of an anti-heat stress feed additive, that is, adding the above-mentioned feed additive to livestock and poultry feed, preferably, adding 300-500 g of the feed additive per ton of livestock and poultry feed Add to.

Embodiment 1

[0034] Weigh 70g of γ-aminobutyric acid, 60g of L-arginine, 90g of α-ketoglutarate, 70g of taurine, ferulic acid esterase (1×10 5 U / kg) 250g, xylanase (5.5×10 6 U / kg) 300g, cellulase (6×10 5 U / kg) 100g and starch 60g, cross 40 mesh sieves after mixing, obtain 1kg feed additive, and add in the corn soybean meal ration of meat duck with the addition amount of 300g / t.

[0035] Select 105 healthy 1-day-old meat ducks with similar body weight and randomly divide them into 7 replicates according to the principle of similar body weight and half male and female. Each replicate has 16 ducks. They are fed with the same amount of the above-mentioned rations every day. The test lasts for 42 days. , Keep the temperature in the duck house at 31-33°C during the test. The production performance data of meat ducks are shown in Table 1.

Embodiment 2

[0037] Weigh respectively 40g of γ-aminobutyric acid, 80g of L-arginine, 90g of α-ketoglutarate, 80g of taurine, ferulic acid esterase (1×10 5 U / kg) 150g, xylanase (5.5×10 6 U / kg) 350g, cellulase (6×10 5 U / kg) 150g and starch 60g, pass through 40 mesh sieves after mixing, obtain 1kg feed additive, and add in the corn soybean meal ration of weaned piglet with the addition amount of 300g / t.

[0038] Select 7 healthy 21-day-old weaned piglets with similar body weight, randomly divide them into 7 replicates according to the principle of similar body weight, and feed one piglet with the same amount of the above-mentioned diet every day. The experiment lasts for 21 days. The temperature in the house is 31-33°C. The production performance data of weaned piglets are shown in Table 1.

Abstract

The invention belongs to the technical field of livestock and poultry feeding, and particularly provides a heat-stress-resistant feeding additive, a preparation method and application thereof.The heat-stress-resistant feeding additive is prepared by compounding gamma-aminobutyric acid, L-arginine, alpha-ketoglutaric acid, taurine, feruloyl esterase, xylanase and cellulase, the additive has the effects of calming nerves and resisting anxiety, has a protective effect on acute heat stress intestinal mucosa immunity, can relieve intestinal mucosa inflammatory response, can also improve the sugar utilization rate in livestock and poultry feed and increase carbon sources, thereby being beneficial to sugar metabolism, lipid metabolism and protein metabolism of livestock and poultry, and finally improving the production performance of the livestock and poultry.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry feeding, and specifically provides a heat stress-resistant feed additive, a preparation method and an application thereof. Background technique [0002] Adding antibiotics to the diet of livestock and poultry can improve the immunity of livestock and poultry, but long-term and excessive use will bring about the problem of drug resistance of pathogenic bacteria, resulting in the emergence of antibiotic-resistant bacteria that are resistant to antibiotics, seriously endangering food safety . Finding new green, pollution-free, safe and efficient feed additives has become a hot spot in the current feed industry. [0003] Poultry is sensitive to heat stress, and heat stress has become one of the important factors restricting the development of the current poultry industry. Broiler chickens are covered with feathers and have no sweat glands, and have poor heat dissipation ability. The op...
