Abstract

The invention discloses a duck premix for enhancing the hatching egg fertilization rate. The premix is composed of various vitamins and trace elements necessary in a duck growth process and a ball-milled mixture of rice bran and hulls. Specifically, the vitamins include vitamin A, vitamin D3, vitamin E, vitamin B2, vitamin B1, vitamin B6, vitamin B12 and vitamin K3; and the trace elements include calcium pantothenate, niacin, folic acid, biotin, ferrous sulfate monohydrate, copper sulfate pentahydrate, zinc sulphate monohydrate, manganese sulfate monohydrate, sodium selenite, and chromium picolinate. The premix provided in the invention not only meets the basic nutritional needs of ducks, but also appropriately increases the content of some trace elements, thus being able to effectively prevent the decline of duck semen quality and ensure the fertilization rate and hatching rate of hatching eggs. By combining bulk raw materials with the premix provided in the invention, other nutritional substances needed by hatching drakes during a breeding period can be replenished. Therefore, the premix is very convenient and is easy for mass promotion.

Description

technical field

[0001] The invention relates to a premixed material for feeding meaty ducks during the growing period, in particular to a premixed material capable of improving the breeding performance of meaty ducks and increasing the fertilization rate of breeding eggs. It belongs to the field of poultry feed. Background technique

[0002] The meat duck industry is developing rapidly, and more and more duck products are favored by people. The scale and quantity of meat duck breeding are increasing rapidly, and the demand for meat duck seedlings is also increasing, resulting in the phenomenon that the supply of duck seedlings exceeds the demand from time to time. The fertilization rate of breeding eggs is significantly positively correlated with the hatchability rate, and directly affects the production performance of commercial meat ducks. Therefore, it is very necessary to develop a feed that can improve the fertilization rate of breeding eggs.
