Compound premix for promoting development of body sizes and ovaries of laying hens

Abstract

The invention discloses a compound premix for promoting the development of body sizes and ovaries of laying hens, which belongs to the field of animal nutrition. According to the invention, vitamin A, vitamin D3, vitamin E, copper, manganese, zinc and various Chinese herbal medicines which are closely related to the growth and development of skeletons and reproductive systems and the stress resistance of the laying hens are elaborately selected, and according to the synergic and antagonistic relation of the selected ingredients, dedicated compound vitamin, compound microelements and compound Chinese herbal medicine preparations are developed. On the basis of the ingredients, oil powder, choline chloride, calcium hydrophosphate, limestone powder, table salt, probiotic, phytase and the like are specially added. By virtue of the elaborate match of the raw materials, the special premix of the laying hens can promote the growth and the reproductive system development of the laying hens, improve the body sizes of the laying hens, enhance the disease-resistant and stress-resistant capabilities of the laying hens and lay a good foundation for improving the laying performance of the laying hens during an egg layering period.

Description

technical field [0001] The technology of the invention belongs to the field of animal nutrition and relates to a feed, in particular to a compound premix for promoting the body shape and ovary development of laying hens. Background technique [0002] In the production of laying hens in my country, there are often problems such as low egg production rate during the peak egg production period and the maintenance time of the peak egg production period is short or even not reaching the peak, resulting in a low overall production level of laying hens, which directly affects the economic benefits of laying hens. The reasons are: chicken group type dysplasia, low feeding and management level, diseases, etc. Among them, chicken group type dysplasia accounts for 68.7% of the factors, ovarian dysplasia accounts for 11%, diseases account for 9.6%, and feeding management accounts for 7.4%. Other factors accounted for 3.3%. Therefore, chicken group type and ovarian dysplasia are the main ...

AI Technical Summary

Problems solved by technology

In the production of laying hens in my country, high-intensity and frequent immunization, medication, and beak trimming during the brooding period have relatively large negative effects. The nutritional needs of stress in this period are not considered in the nutritional supply, so that the nutrition of the brooding diet cannot meet other needs. Due to actual needs, the body size indicators (shin length, weight) in the brooding period are not up to standard; the nutritional level of the rearing diet is low, and the quality of raw materials used is generally poor. Adjust the nutrition of the diet according to the situation, so that the stunted body shape is not compensated in the growing period; the expected laying period (later growing period) is the period of rapid development of the reproductive organs of laying hens, which requires a higher nutritional level of pre-laying feed, and low nutrition is still used in production The diet affects the development of ovaries, fallopian tubes, etc., and makes the reproductive system insufficient
