specific Embodiment approach 1

[0009] Specific embodiment one: the laying duck anti-cold and egg production additive of this embodiment is composed of 4% vitamin E, 25% vitamin C, and 1.5% vitamin B by mass percentage 2 , 0.0375% of the selenium element and the rest of the carrier; wherein the selenium element is provided by sodium selenite; the carrier is cornmeal, corn gluten flour, corncob flour, rice husk flour, wheat bran or sub-wheat flour.

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

specific Embodiment approach 2

[0011] Specific embodiment 2: The application of the laying duck anti-cold additive to promote egg production in this embodiment: the laying duck is added 0.035% to 0.045% by weight in the full-price diet of the laying duck under the condition of 0°C to 5°C % laying duck cold-resistant additives to promote egg production.

specific Embodiment approach 3

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

[0013] In this embodiment, the egg production rate of laying ducks 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. The invention 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 ducks are 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 invention relates to an additive for promoting egg production and its application. Background technique [0002] In the northern alpine region, the cold stress caused by the low temperature environment is one of the main factors restricting the development of animal husbandry in the north. Therefore, solving this difficult problem affecting animal husbandry production has become the frontier of nutritional physiology and poultry environmental nutrition research. hotspot. [0003] At present, in northern my country, laying ducks suffer from physical decline, increased feed consumption and reduced egg production during cold and low temperature seasons. Contents of the invention [0004] The object of the present invention is to provide a laying duck cold-resistant and egg-laying-promoting additive and its application in order to solve the problems that the laying ducks in northern my country suffer from physical decline, increased feed consumption...
