The introduction of snakes
The quality of introduction is related to the survival rate and production capacity of snakes. The acquisition of snake species can be approved by the relevant management departments to catch snakes in the wild, and it is necessary to introduce species of snakes if local snake resources are scarce.
1. The best season for introduction is in spring and autumn.
The weather is suitable in spring, and breeding can enter the spawning period or breeding period soon after introduction, which is especially suitable for beginners. Autumn is also a good season for introduction, because it is neither too cold nor too hot, and it is the peak season for snakes to hunt and the strongest time of the year. Farmers who travel a little farther can introduce snakes in this season. It is more appropriate for beginners to raise half-big snakes (young snakes). Because the semi-big snake is better than the small snake in growth, disease resistance and feeding, it can adapt quickly in the new living environment.
two。 Introduction of artificial snake farm
Snake species should be introduced from large-scale snake farms, and snake species should come from different places to prevent inbreeding as far as possible. Do not buy snakes sold in snake markets or farmers' markets, in case you buy shoddy snakes that have just been forcibly fed or filled with sand or water, or poisonous snakes that have been pulled out their fangs.
3. Catch or buy snakes
The choice of parents must be long and strong. The specifications of imported snakes are as follows: 100g for general small varieties, 150g for medium varieties and 250g for large varieties. Lively and active, flexible, ferocious and energetic, full of muscles in the shape of a cylinder, shiny body surface, bright skin patterns, no injury or disease is preferred. For the time being, it is difficult to determine whether there is any illness or injury, you can first isolate and try to raise.
When checking for internal injuries, the snake can be crawled on the ground to see if it is flexible and natural, or after grasping the head and tail with both hands and straightening naturally, the snake has a strong curling ability, indicating that there are no internal injuries, on the contrary, it cannot be used as a kind of snake. If the skin is slightly injured and there is no internal injury, it can also be used as a kind of snake as long as it is cured with iodine tincture. Secondly, check for gallbladder. Some snake catchers cut open the gall bladder with a sharp blade, sew it up with a needle, and then sell it on the market. The gallbladder-free snake can survive for some time, but it cannot be selected as a species. Third, check whether the fangs are complete. For those who choose to buy venomous snakes as seeds, they also need to open the snake's oral cavity to see if there are complete fangs. Because some snake catchers after catching the snake, in order to avoid the damage of fangs, open the snake's mouth with sharp weapons and rudely pull out the fangs, this kind of non-fangs snake is difficult to feed in the future, so it can not buy and keep species. If you find that the snake's expression is dull, does not like to stick out its tongue, the body is thin, the scales are dry and loose, and the color loses its luster, this kind of snake may be infected with disease and should not be used as a seed. Attention should be paid to the reasonable collocation of male and female in the introduction of snake seedlings. Generally speaking, the female-to-male ratio is 5:1.

Identification and management of hateful doe
Every year during the birth and lactation period of female deer, due to the lack of management skills in some deer farms, the phenomenon of hateful female deer harming newborn deer and feeding managers occurs from time to time. Some newborn deer are killed alive, and some breeders or technicians are scratched. According to the investigation, a sika deer hated female deer killed five newborn deer in the first few days of her birth, and scratched two young and able-bodied managers. The harm of hateful female deer has led to a significant increase in the mortality of young deer, which should be paid full attention to. 1 recognition

Application of melatonin in Fox Industry
Melatonin is an indole hormone secreted by the pineal gland in the animal brain, also known as pineal gland hormone. It was first applied in fur farms in North America in 1985. China solved the technology of synthetic melatonin and manufacturing melatonin implants in domestic chemical raw materials at the beginning of 1993. After 1998, melatonin is widely used in fur breeding in Northeast China. Melatonin has been used in Dongjin improved breed livestock farm in Xiangfan City, Hubei Province since 1999. in the course of 8 years of practical application, melatonin can induce fox fur to mature ahead of time and delay public silver black.
