Problems solved by technology

Studies have shown that during the egg-laying period of ducks, even if the stress intensity is not high, the continuous or intermittent slight reactions caused by continuous or intermittent repeated efforts will form an adverse cumulative effect due to the continuous adaptation efforts of the body, destroying

Embodiment 1

[0024] A feed additive for enhancing the anti-stress ability of breeding ducks during laying, comprising the following raw materials in percentage by weight: 3 parts of isochlorogenic acid, 3 parts of tributyrin, 2 parts of acetylglucosamine benzoate, 8 parts of puffed Chickpea flour, 2 parts Hypericum perforatum, 2 parts bile acids.

[0025] The preparation method of above-mentioned feed additive comprises the following steps:

[0026] (1) Preparation of Hypericum perforatum extract: select high-quality Hypericum perforatum, wash and remove impurities, and dry at 75-80°C for 60-90 minutes, then place the dried Hypericum perforatum in a pulverizer to pulverize, and then sterilize Finally, obtain 150-300 mesh Hypericum perforatum powder; extract Hypericum perforatum powder twice, add water for the first time to 8-10 times the weight of Hypericum perforatum powder, heat to boil and keep for 30-45min, collect the first extract Add water to the Hypericum perforatum powder for the...

Embodiment 2

[0030] A feed additive for enhancing the anti-stress ability of breeding ducks during laying, comprising the following raw materials in weight percentage: 4 parts of isochlorogenic acid, 1 part of tributyrin, 4 parts of acetylglucosamine benzoate, 7 parts of puffed Chickpea flour, 1 part of Hypericum perforatum, 3 parts of bile acid; the isochlorogenic acid is the total isochlorogenic acid extracted from Stevia rebaudiana.

[0031] The preparation method of the additive of this embodiment is the same as that of specific embodiment one.

Embodiment 3

[0033] A feed additive for enhancing the anti-stress ability of breeding ducks during laying, comprising the following raw materials in weight percentage: 4 parts of isochlorogenic acid, 1 part of tributyrin, 3 parts of acetylglucosamine benzoate, 9 parts of puffed chickpea flour; the isochlorogenic acid is the total isochlorogenic acid extracted from Stevia rebaudiana.

[0034] The preparation method of above-mentioned feed additive comprises the following steps:

[0035] (1) Mixing and granulation: Mix the isochlorogenic acid and expanded chickpea flour in the machine according to the weight ratio, the mixing time is 120-150s, the coefficient of variation of mixing uniformity is ≤4%, and enter the granulator after mixing Granulation to obtain granular products;

[0036] (2) Spraying: Dissolve tributyrin and acetyl glucosamine benzoate in ethyl acetate respectively, and spray tributyrin solution and acetyl glucosamine benzoate successively on the granular product obtained in...

Abstract

The invention discloses a feed additive for enhancing the anti-stress ability of breeding ducks in the egg laying period and a preparation method of the feed additive. The additive comprises the following raw materials in percentage by weight: 3-5 parts of isochlorogenic acid, 1-3 parts of tributyrin, 2-4 parts of acetylglucosamine benzoate and 6-9 parts of puffed chickpea powder. The additive further comprises 1-3 parts of hyperforin perforatum and 1-3 parts of bile acid. The preparation method comprises the following steps: preparing a hyperforin perforatum extract: adding water twice for extraction, combining the two extracting solutions, concentrating to obtain paste, and drying to obtain the hyperforin perforatum extract; mixing and granulating to obtain granular products: wherein the variable coefficient of the mixing uniformity is less than or equal to 4%; sequentially spraying a tributyrin solution and an acetylglucosamine benzoate solution on the granular product; and drying. When the additive is added into the breeding duck feed, the physique, the resistance, the adaptive capacity to change of external factors such as feed changing and illumination increasing of the breeding ducks and the anti-stress capacity after egg laying can be effectively enhanced, and the overall economic benefit of duck breeding is improved.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a feed additive for enhancing the anti-stress ability of breeding ducks during laying and a preparation method thereof. Background technique [0002] In recent years, with the increase of people's demand for duck eggs, salted duck and other duck products, the amount of duck breeding has developed rapidly, and the demand for duck seedlings has also increased sharply, which puts forward higher requirements for the production capacity of breeding ducks. [0003] The expected laying period of meat ducks is generally 17-25 weeks old. This period is an important period for ducks to transition from the breeding period to the laying period. If the feed or management is improper, the peak laying period will be delayed or even not appear, which is serious. Affect the production performance of breeding ducks. [0004] Animals live in an environment full of stressors, and any change ...
