What are the general principles for raising velvet deer?
(1) Scientifically and rationally match the feed. To improve the production performance of deer, the feed should be scientifically and rationally matched according to local feed sources, types, reserve quantities, feed quality, deer management conditions, etc., so as to meet the nutrient requirements of velvet deer. Velvet deer have different nutritional needs at different stages. For example, male deer need more nutrition during the mating period and antler-growing period than female deer, while female deer need even more nutrition during pregnancy and lactation. Therefore, during the feeding process, feed supply plans should be prepared in advance to ensure that feed can be matched and adjusted promptly, scientifically, and rationally, so as to achieve good results.

What are the basic principles of fish health management
The concept of fish health management is that fish raised under such conditions will achieve optimal growth rate, feed conversion rate, reproduction rate and survival rate. Maintaining a high-quality aquatic environment and feeding nutritionally balanced feed are very important for maintaining fish health and preventing fish from becoming diseased. Proper fish health management should aim at environmental, nutritional, economic and other factors to prevent fish diseases rather than focusing on treating fish diseases. The following are some basic principles of fish health management. 1. Pay attention to the environment

Principles and Methods of Oral Medication for Preventing Rice Field Eel Diseases
Also called the oral administration method, it generally involves mixing the medication to be used into the feed at the prescribed dose to make medicated bait, so that the rice field eel ingests the medication by eating the feed, thereby achieving the purpose of preventing and treating diseases. The problem with using this method is that usually once rice field eels become ill, it becomes a group outbreak, with generally reduced appetite or almost complete cessation of feeding, meaning that the amount of medication entering the rice field eels' bodies will not be very large, and the treatment effect will not be very good either. Therefore, certain technical measures need to be taken to do everything possible to get the sick rice field eels to better ingest the medicated bait, such as stopping feed

Detailed Explanation of the Basic Principles for the Use of Fishery Drugs
The use of fishery drugs is based on the basic principle of not harming human health and not damaging the aquatic ecological environment. In the aquaculture process, the prevention and control of diseases and pests in aquatic animals must adhere to the principle of giving priority to prevention, with treatment as a supplement. The use of fishery drugs should strictly follow the regulations of the state and relevant departments, and it is strictly prohibited to produce, sell and use fishery drugs that have not obtained a production license, approval number, or production standard. Actively encourage the research, development, production and use of fishery drugs that are highly effective, fast-acting, long-lasting, and have low toxicity, few side effects and small dosage, and advocate the use of drugs specifically for aquatic products, biological fishery drugs and fishery biological

Principles of preventive medication for eel diseases and how to use the hanging bag method
Also called the hanging basket method. Bags or baskets containing medicine are hung around the feeding ground (platform) to form a medicated zone, so that when rice field eels enter this zone to feed, pathogens on their body surface are killed. This method has the advantages of using a small amount of medicine, being simple and convenient, being safe, and having few side effects. However, it also has the disadvantage of not completely killing pathogens. It is generally used to prevent diseases.

What are the principles for selecting breeding pairs in dogs? A detailed explanation of the precautions
Selecting breeding pairs in dogs means choosing suitable male and female dogs to mate, that is, how to choose suitable mates for male and female dogs. The principles are as follows: (1) Choose male and female dogs that share common strengths to mate, so that their strengths are maintained, consolidated and developed in the offspring. (2) Male and female dogs that share common faults must not be mated; if they are mated, the faults of both will become more firmly established. (3) When good breeding dogs are in short supply, a dog with a certain strength may be mated with another dog that has the corresponding fault, using the strength to overcome the fault.

Principles and methods of the medicated immersion method for preventing eel diseases
Also called the immersion method, it involves concentrating the rice field eels in a smaller body of water or container, preparing a relatively high-concentration medication, and forcing the eels to be exposed to the medication for a short period of time to achieve the purpose of killing pathogens. For example, when stocking, use salt to immerse the eel fry, etc. Its characteristics are: first, it is mostly used to kill pathogens on the body surface or gills; second, it is mostly used for disinfecting fry and seedlings or tools at the time of stocking; third, it requires that the concentration of the medication be precise during operation, and that the operation time be short, the speed fast, and the movements gentle.
