The razor is getting smaller and smaller. Why?
(1) Variety degradation: variety degradation degrades production performance, which leads to razor buds eating only and not gaining weight. (2) serious selenium deficiency: selenium deficiency causes animals to suffer from white muscle disease, muscle atrophy and gradual weight loss. (3) parasitic infection: eperythrozoonosis and so on. Sodium selenite and vitamin E injection were used during treatment. It takes a long time to cure by intramuscular injection or feed mixed with sodium selenite powder. In the process of feeding, trace elements and various nutrients should be supplemented with full-price feed.

How do dogs mate?
The male dog has a special penile bone and does not need an erection when mating. When inserted into the female dog's vagina, the cavernous body of the urethra and the corpus cavernosum of the penis are rapidly congested and swollen and are stuck by the anterior edge of the pubic bone of the female dog, so that the corpus cavernosum of the penis cannot be withdrawn. After 45 minutes of 10Murray, the ejaculation ends and the corpus cavernosum shrinks before the penis can exit. Male dogs cannot mate more than once a day. Hot weather should be carried out in the early morning or evening. Do not mate within 2 hours after eating to avoid reflex vomiting in male dogs. After mating, don't forget to put the mating date, the name or number of the male dog, and mating
