Microelement composition for improving reproductive performance of breeding hens

Abstract

The invention discloses a microelement composition for improving the reproductive performance of breeding hens. Each 1 kilogram of the composition comprises the following components by mass: 2 to 4 grams of chalcanthite, 20 to 30 grams of ferrous sulfate monohydrate, 20 to 35 grams of zinc sulfate monohydrate, 10 to 30 grams of manganese sulfate monohydrate, 2 to 5 grams of potassium iodide, 3 to4 grams of sodium selenite, and 943 to 892 grams of carrier. The microelement composition is used for the breeding hens, and can maintain the normal vital movements of the breeding hens, improve the immunity, the disease resistance and the anti-stress capability, prevent deficiency diseases, reduce the feed consumption, and improve the laying rate, and the fertility rate and the hatchability of hatching eggs. The composition has no toxic side effects and has small influence on the environment.

Description

technical field

[0001] The invention relates to a trace element composition for improving breeding performance of breeders, more specifically, a trace element composition for breeders rich in various trace elements. Background technique

[0002] There are few research materials on the requirements of trace elements in animals, and the lack of operability is mainly due to the complexity of the absorption and metabolism of trace elements in the body, the limitations of research methods and high cost, and the lack of research on coordination and antagonism between trace elements . Different animal species and growth stages have different bioavailability of different trace elements. Random addition will not only affect the growth of animals, but also increase costs, pollute the environment, and waste resources.

[0003] Trace elements are closely related to animal health. The main effects of trace elements on animals are as follows:
