A device and preparation method for controlling animal follicle development and preventing reproductive tract inflammation

Abstract

The invention provides a device and a preparation method for controlling animal follicle development and preventing and treating reproductive tract inflammation. The inside of the device is a nylon stent, and the outside of the stent is wrapped with a slow-release material layer mixed with estrogen, progesterone and antimicrobial peptide; the device has a connecting part and two long arms, and the bottom ends of the two long arms are respectively connected with the connecting part. And a certain included angle is formed between the two long arms; the slow-release material layer at the long arms protrudes to form a number of orderly arranged sheet-like structures. The invention mixes the medicine with the silicone rubber raw material according to a certain ratio, and after low-temperature vulcanization and molding, forms a special vaginal embedding plug with a polymer material bracket. The medicine combined with silicone rubber can be released slowly for a long time (more than 10 days), so as to effectively control the development of follicles in animals, and prevent and treat inflammation of the vagina and uterus. The material used in the invention is non-toxic and harmless, smooth and soft in texture, and has good compatibility with animal tissues; the operation of putting in and taking out the inventive device is simple.

Description

Technical field [0001] The present invention belongs to the animal breeding field of animal husbandry veterinarians, aimed at providing a vaginal embedding apparatus for controlling animal follicles development and prevention of genital tract inflammation and its preparation methods. Background technique [0002] my country is a raised raft, raising pigs and defenders. At present, the total number of sheep and goats are close to 400 million. The number of pigs in pigs is 480 million, and the feeding of deer is more than 600,000. With the adjustment of the industrial structure and the improvement of environmental protection requirements, intensive and scale breeding have gradually become mainstream. The corresponding, reproductive control technology and the prevention and control of obstetric diseases have increased rapidly. For example, eating and sows, ovulation regulation, and timed artificial insemination technology can reduce group empty time, shorten the lamb interval, quick...
