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.

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.
