Problems solved by technology

However, only adding Artemisia annua to broiler diets does not significantly improve the intestinal morphology of broilers, and there is still room for improvement
[0006] The research on relieving heat stress through dietary nutrition regulation mostly focuses on the prevention and control technology of a single factor. Can reducing dietary protein levels and applying Artemisia annua and other plant-derived additives together as additives to relieve heat stress can play a role? The effect of alleviating heat stress has not yet been reported, nor has there been any relevant research report on the application in poultry production

Embodiment 1

[0035] This experiment was carried out in Jurong Haoyuan Ecological Agriculture Technology Co., Ltd.

[0036] 1) Adjusting the crude protein level of the diet: the test objects are laying hens during the laying period. The basal diet formula used for laying hens had a crude protein level of 15.85%. The low-protein diet adjusted the diet formula on this basis, reduced the content of soybean meal, and reduced the crude protein by 2 percentage points to 13.85%.

[0037] 2) Supplementing crystalline amino acids: Supplementing crystalline amino acids in the diet reduced by 2 percentage points of crude protein makes the levels of the main amino acids methionine, lysine, threonine and tryptophan consistent with the levels of the original formula. The diet formula is shown in Table 1.

[0038] Table 1 Basic diet and low protein diet composition and nutrient level%

[0039]

[0040] 3) Application of Artemisia annua and Astragalus: Add Artemisia annua powder or Astragalus powder ...

Abstract

The invention discloses a poultry feed nutrition regulation and control method in a high-temperature environment, which comprises the following steps: (1) preparing a low-protein feed on the basis of a basic feed formula; (2) a plant source additive is added into the low-protein feed, the blended feed is obtained, and the plant source additive is any one or a mixture of sweet wormwood herb powder and radix astragali powder; and (3) feeding the blended feed to poultry in a high-temperature environment. The artemisia apiacea and the astragalus membranaceus are applied to the poultry feed in a high-temperature environment, the protein level of the feed is reduced, the effects of relieving poultry production performance reduction and physiological index disorder caused by heat stress are achieved, and particularly after the astragalus membranaceus is added, the intestinal morphological structure of poultry is remarkably improved, and the stable state of the environment in the intestinal tract is maintained.

Description

technical field [0001] The invention relates to a method for regulating the nutrition of poultry feed, in particular to a method for regulating the nutrition of poultry feed under a high temperature environment, and belongs to the technical field of animal nutrition and feed. Background technique [0002] Appropriate ambient temperature is very important for animals to achieve ideal production targets. Heat stress is one of the major environmental stressors that endanger animal production worldwide. Heat stress is divided into acute heat stress and chronic heat stress. Acute heat stress refers to a rapid and brief rise in ambient temperature, chronic heat stress refers to a prolonged period of high ambient temperature (days or weeks), and chronic heat stress. Heat stress is subdivided into chronic cyclic heat stress (high temperature during part of the day and normal temperature at other times) and chronic persistent heat stress (animals are continuously exposed to high tem...
