The weather in autumn is cool, the pasture is abundant, the fodder is abundant, the bull is energetic, and the cow has a short estrus cycle and long duration. It is the golden season for breeding. Should grasp the following points: Strong Zhuang: Before the breeding period, cows of moderate age should have a moderate body condition. Over-fertility or thinness are not conducive to breeding. Cows with poor body condition can adjust the feed ratio appropriately, increase the number of nutrition and feeding, and extend the grazing time, mowing the grass to feed the cows and prompting the cows to ovulate. Aphrodisiac: In order to ensure that cows can heat in the best conceived season and increase the rate of conception, cows that are not estrus can be appropriately agitated. 1 induced feelings. With estrus bulls chasing non-estrus cows, urging cows to heat. 2 hormone aphrodisiac. For estrus-producing cows, 40-60 mg of diphenol ethane or 3 to 5 grams of triads may be used. After the cow is injected, it can be used for estrus. 3 Chinese herbal aphrodisiac. Use motherwort 30 grams, pumpkin leaves 24 grams, safflower 15 grams, Jianshui to cattle gavage, or use the old jujube tree split skin 0.5 kg, brown sugar 1 kg, add water 3 kg, Jianshui to cattle early and late Irrigation once, even for 2 to 3 days.

At this point touch the cow's buttocks, oxtail Gao Qiao, quiet, two hind legs open for mating action. After the appetite gradually recovers, the libido declines, the vulva swelling gradually subsides, and the mucous is small and thick. At this time, it is most suitable to breed or inseminate the cow. The use of artificial insemination is an important measure to increase the conception rate of cows, especially for the rectal grasp method. During operation, insert the vas deferens flatly into the cervix 5 to 7 centimeters, then slowly inject semen. After the insemination is completed, slowly pull the vas deferens to prevent damage to cow vagina or semen. Strengthen management: During the breeding period, bulls should be fed with green feed and concentrates, and when they are busy, animal feeds such as eggs and fishmeal should be fed. Within 1 to 2 hours after the cows are mated, do not exercise vigorously. Avoid drinking or eating too much. After 15 days of mating, feeding is carried out at the same time, 1 to 1.5 kg of wheat bran is added, and clean drinking water containing a small amount of salt is supplied to promote fertilized egg implantation. During pregnancy, cows feed protein-, vitamin-, and mineral-rich feeds to suit cow growth and fetal, placental, and uterine developmental needs; they must not be fed mildew, spoilage, freezing, toxic, excessive acidity, or Strongly irritating feed to prevent enteritis, miscarriage, weak or stillbirth.
