First, choose a good breed. To choose to keep the fur light, consistent dorsum and color, short hair, hair peak, hair is flush, dense, uniform distribution, soft hair, good strength, slightly longer hair hair, purple hair without white hair, white spots. This kind of fur has good quality and high commodity value. Second, do a good job breeding management. The otters reproduce once a year, and estrus and breeding are conducted every year from February to March. Therefore, the species will enter the breeding season in late January. During the breeding period, public breeding must ensure the supply of high-quality refined feed, and animal feeds such as fresh blood, eggs, milk, liver, and fish account for more than 80%, and at the same time increase the use of yin and yang drugs, Liuwei Dihuang Wan, Epimedium and Vitamin E. B, C, etc. It is necessary to eliminate inbreeding and prevent the otters from degrading. In the later period of pregnancy, the female parent must ensure the supply of high-quality feed. When slaughtered animals feed, organs such as the adrenal gland and pituitary gland containing sex hormones must be removed to prevent fetal death or miscarriage after the mother's foraging. Third, pay attention to insulation, increase the survival rate of larvae. After the birth of Aberdeen, a hot water bottle should be placed on the upper and lower sides of the farrowing box to keep the survival rate of the larvae alive. Fourth, prevent diseases. Generally during the period of the fastest growth and development of juveniles (July and August), the temperature is high, the air humidity is high, and the feed is susceptible to deterioration. Minamata is very susceptible to gastrointestinal diseases. Digging fresh purslane, sorrel, psyllium, violet, dandelion and other herbs to feed. In this way, feed costs can be reduced, heatstroke can be prevented, and gastrointestinal infectious diseases such as enteritis and dysentery can be prevented. In June and July, vaccines such as canine distemper, paratyphoid fever and pasteurella should be administered to prevent infection. The vaccination site is on the inside of the posterior thigh. Fifth, the use of food substitutes. In order to reduce costs, soy flour and peanut cakes can be used instead of some meat products, and sweet potatoes can be used instead of some vegetables, with fresh pork blood, eggs, and milk to enhance palatability. Sixth, to improve the nutrition during the hair replacement period. During the equinox, when the leeches enter the moulting period, this is a critical period for improving the quality of the fur. In addition to feeding high-quality concentrates, vegetable oils (bean oil, peanut oil, etc.) and vitamin B2 should also be added to the feed. Milligrams. Seven, mature skin. The mink can be slaughtered after the hair has been changed. Take a mature skin when taking one, must not be a batch of skin. When you slaughter, you must pay attention to the integrity of the fur, and must not cut the fur, otherwise it will reduce the level of fur.
