specific Embodiment approach 1

[0009] Embodiment 1: In this embodiment, the cold-resistant and egg-laying-promoting additive for laying ducks is composed of 4% vitamin E, 25% vitamin C, and 1.5% vitamin B by mass percentage. 2 , 0.0375% selenium element and the remainder of the carrier; wherein the selenium element is provided by sodium selenite; the carrier is corn flour, corn gluten meal, corn cob meal, rice husk meal, wheat fine bran or subwheat flour.

[0010] In this embodiment, vitamin E, vitamin C, vitamin B and sodium selenite are all feed grades.

specific Embodiment approach 2

[0011] Specific embodiment 2: The application of the cold-resistant and egg-laying-promoting additive for laying ducks in this embodiment: Under the conditions of 0°C to 5°C, 0.035%-0.045% by weight is added to the full-price diet of laying ducks. % cold-resistant and egg-laying-promoting additive for laying ducks.

specific Embodiment approach 3

[0012] Embodiment 3: This embodiment is different from Embodiment 2 in that 0.035% of the cold-resistant and egg-laying-promoting additive for laying ducks is added. Others are the same as in the second embodiment.

[0013] In this embodiment, the egg laying rate of the laying duck is increased by 10% under the condition of 5°C.

Abstract

The invention discloses an additive for resisting coldness and accelerating egg laying for laying ducks and application thereof, relating to an additive for accelerating egg laying and application thereof. The additive solves the problems that the laying ducks of northern China have lowered physique, increased feed and decreased egg laying quantity in cold seasons with low temperature. The additive for resisting coldness and accelerating egg laying for the laying ducks is composed of Vitamin E, Vitamin C, Vitamin B2, selenium and rest of carrier. The application of the additive is that under the condition of cold stress to the laying ducks, 0.035 to 0.045% of additive for resisting coldness and accelerating egg laying for the laying ducks is added in adequate diet for the laying ducks. Theinvention improves nonspecific resistance of the laying ducks as well as anti-stress capability, prevents physique from declining, and lightens damage caused by cold stress, so that the laying ducksare in favorable physiological state and perform maximal productivity, feed consumption is normal, eggs laid by the laying ducks have normal size and weight, and egg laying rate is increased from 10%to 16%; the additive has the advantages of small addition and low cost, so that the additive is suitable for popularizing and utilizing on large scale.

Description

technical field [0001] The present invention relates to an additive for promoting egg production and its application. Background technique [0002] In the northern alpine regions, the cold stress caused by the low temperature is one of the main factors restricting the development of animal husbandry in the north. Therefore, solving this problem affecting the production of animal husbandry has become the frontier of nutritional physiology and poultry environmental nutrition research. hot spot. [0003] At present, in northern my country, in the cold and low temperature season, the physique of laying ducks declines, the consumption of materials increases, and the egg production decreases. SUMMARY OF THE INVENTION [0004] The purpose of the invention is to provide a cold-resistant and egg-laying-promoting additive for egg-laying ducks and its application in order to solve the problems that the physique of the laying ducks in northern my country decreases during the cold and...
