Feed additive for enhancing anti-stress capability of breeding ducks in egg producing period and preparation method of feed additive

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 ...

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 the homeostasis of physiological functions, resulting in Its immunity is reduced, and it is easy to be infected secondaryly, and then symptoms such as diarrhea, decreased production performance, and death will occur, which seriously affects the value of breeding ducks and the economic benefits of enterprises.
