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. Production should pay attention to the following questions:
First, before the arrival of the breeding season, the suitable age of cows should have a moderate body condition, too fat or thin 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. Usually, we must pay attention to nutritional balance to prevent excessive intake of protein and energy feed caused by excessive cow obesity, affecting the quality of breeding.
Second, the aphrodisiac In order to ensure that the cow can heat in the best season of pregnancy, improve the conception rate, for long-lost cows may be appropriate to take agitation measures. 1 induced feelings. With estrus bulls chasing non-estrus cows, urging cows to heat. 2 Chinese herbal aphrodisiac.
Third, when the estrus of the timely mating cows, loss of appetite, excited, like to approach the bull, cross each other, often urinating position, but less urine, pus, flushing, congestion, slightly open, often accompanied by white translucent Mucus flowed out, and some cows also had a small amount of blood flowing from the vagina. At this point touch the cow's buttocks, oxtail Gao Qiao, quiet, two hind legs open for mating action. After the appetite gradually recovers, libido subsides, the vulva swelling subsides, and the mucous is swollen and thick (for rectal examination, the estrus is in the follicular maturation or ovulation period). At this time, it is most suitable to breed or inseminate the cow. Artificial insemination is an important measure to increase the conception rate of cows.
Fourth, during the period of strengthening management and breeding, the 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 1-2 hours after the cows are mated, do not exercise vigorously. Try to avoid drinking or eating too much. After 15 days of breeding, feed was added at the same time. At the same time, 1-1.5 kg of wheat bran was added, and clean drinking water containing a small amount of salt was 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. The barn environment should be quiet to prevent miscarriage caused by excessive scaring, colliding, slipping, whipping, or overhead racking.
