Estrus drugs are drugs that can stimulate animals to enter estrus, and are widely used in breeding and research. Its basic components are mainly divided into two categories: one is ovulation induction agent, which can promote the release of animal eggs; The second is luteinizing hormone (LH) and human chorionic gonadotropin (hCG), which can promote the production of lutein in animals. These ingredients are artificially synthesized or extracted from natural resources.
Other widely used estrogen drugs include prostaglandin, gonadotropin-releasing hormone (GnRH) and luteinizing hormone-releasing hormone (GnIH). These components can promote animals to enter estrus and have been widely used in breeding and research.
2. Production of estrous drugs
At present, the production of estrous drugs has been industrialized, scaled and standardized, and its preparation process includes the following steps:
1. Preparation of pharmaceutical raw materials: screening, cleaning and crushing pharmaceutical raw materials to ensure their good quality.
2. Extraction of main components: The main components are extracted from pharmaceutical raw materials through soaking, osmosis, distillation and other steps.
3. Preparation of drug formula: the extracted main components and other necessary auxiliary components are mixed together in a certain proportion.
4. Drug molding: put the prepared drugs into appropriate containers and process them into different dosage forms, such as liquids, capsules, tablets, etc.
5. Drug packaging: packaging the molded drugs, and indicating the usage, dosage, storage conditions and other information.
3, the application of estrus drugs and matters needing attention
Estrus drugs are widely used in animal husbandry, and their main purpose is to accelerate animals to enter estrus and improve fertilization rate and reproductive efficiency. In practical application, we should pay attention to the following points:
1. Read the drug instructions carefully before use and use them in strict accordance with the usage and dosage on the drug instructions.
2. Touch medication should pay attention to personal hygiene and animal hygiene, and ensure the disinfection of tools and the cleanliness of hands.
3. Drugs should not be used excessively, and only the recommended dosage should be used to avoid some unexpected negative effects on animals.
4. After taking medicine for a period of time, it is necessary to monitor the pregnancy of animals to ensure the inoculation effect.
4. Risks and safety of estrogen drugs.
The use of estrogen drugs has certain risks, and if it is used improperly, it may cause some adverse reactions in animals. Estrous drugs may lead to abnormal behavior of animals, and may cause postpartum toxemia and other diseases after use. In addition, hormone drugs may also have adverse effects on human health. Therefore, the instructions should be strictly followed when using them to avoid adverse effects on animals and humans.
