First, breeding time should try to avoid the high temperature, because the female rabbit has a higher litter size in the environment below 25 °C, so should be in the morning and evening when the weather is relatively cool when the mating, when the rabbit's mental status is better, conceived The rate is higher. In addition, the feeding time should be avoided so that the male rabbit does not think that the female rabbit came to snatch food and cannot mate. In addition, it is also important that the female rabbits choose the best breeding time during the estrus period. The entire estrus period is divided into the early period, the middle period and the later period. The discrimination mainly depends on the change of the genitals. Unestrusated female rabbits are not swollen in the pudendal area and are normally flesh-white; pre-estrus becomes more humid, slightly swollen, pink; mid-term moist, swollen and reddish (commonly known as old red); later moist, swollen, purple and black. The best breeding period is in the middle and late stages of heat. Therefore, there are slang phrases like "Pink early, purple late, and old red".
Second, we must reasonably arrange male rabbits can not be long-term unworthy, can not be over-matching, the general breeding female rabbits will be caught in a rabbit cage. If the female rabbit does not accept the mating, another male rabbit may be exchanged, but it is better to put the female rabbit back into the original cage for a while. After the peculiar smell disappears, the female rabbit is then caught in another male rabbit cage for breeding. Otherwise, when the female rabbit has the odor of the previous male rabbit, the latter male rabbit is not only unworthy, and may even bite the female rabbit.
Third, to grasp the female rabbit's initial mating age The female rabbit's initial mating age is between 5 and a half months to 7 months of age. The average mating age of a medium rabbit is 5 and a half months, and that of a small rabbit is 5 months. Large rabbits are six and a half months old. In order to increase the breeding rate, some breeders will mate with rabbits that are not sexually mature and have a mating age. The result may not only cause fetuses, weak babies, or undergrowth fetuses, but also the growth and health of rabbits themselves. .
Fourth, the ageing matching of the so-called age matching is a reasonable choice based on the mating age of the two rabbits. It is generally believed that the rabbits in the prime of life have the strongest viability. The species performance of the old rabbits declines with age, while the young rabbits generally lack mating experience. Therefore, the young males and females mated with each other, and the matching rate was low. The born puppies are also weak and the survival rate is not high. Practice has proved that the offspring born to mating males and females have the best performance in terms of viability and production performance. Therefore, in the production practice, the old rabbit should be avoided as much as possible with the aged rabbit or the young rabbit. Young rabbits that are too old or younger than the initial age should be prohibited from breeding. Therefore, under normal circumstances, a young adult rabbit is equipped with a young rabbit, a young rabbit and an old rabbit.
Fifth, to improve the way of breeding One is a double match. About 10 minutes after the first breeding, another male rabbit is used for the second time. This method can only be limited to the production of goods, because as a seed can not determine the father's blood. The repeats were reconstituted with the same rabbit 6-8 hours after the first mating. Since rabbits are stimulating ovulatory animals, their ovulation time is about 10 hours after mating. Therefore, double matching or repeated matching can often increase the rate of conception and promote multiple ovulation of female rabbits.
Sixth, pay attention to the reasonable arrangement of male rabbits breeding the number of long-term unmatched or over-mating rabbits can cause infertility or infertility. Because male rabbits are unfit for a long period of time, the aging or dead sperm in the accumulated epididymis will be increased; over-breeding will make sperm production impossible to follow and the semen concentration will be poor, with immature or abnormal spermatozoa also increasing. Therefore, the number of general reasonable breedings is roughly once per day, with 2 days of rest for 1 day.
