At present, it is a good time for rabbits to pluck in autumn. To speed up reproduction, we must implement three urges on rabbits.
In the autumn, sooner or later, cool, rabbits have increased appetite. Mixed concentrates should be fed in the morning and at night. At night, concentrates should feed 2/3 of the diet, and provide clean drinking water. At other times, they should feed high quality roughage. After re-feeding, feed more protein-rich feeds, such as soy, bran, fish meal, germinated barley, and silkworm cocoons. The mixed concentrate contains digestive energy of 2,900 kcal/kg, crude protein of 18%, and crude fiber of 10%. And add 1% salt and 20% bone meal or stone powder.
After being escorted into the autumn, it is necessary to grasp the estrus period of the female rabbits. The female rabbits are estrus for 7 to 15 days once, and each time lasts for 3 to 4 days. When the female rabbit is in estrus, it shows redness and swelling of the genitals, and some vaginas will flow out of mucus, and will give out a buzzing sound and run around. At this time, it is necessary to grasp the timing of mating with “pink early, purple later, and scarletâ€, that is, when the female genitalia is large red, it is most appropriate to breed, so that the rate of conception can be improved, and double matching can be achieved. Two male rabbits were assigned to the same rabbit or the same male rabbit was allocated once every 8 hours. High temperature has a greater impact on sexual performance in male rabbits, and sudden mating results in low fertility rates. After the beginning of autumn, artificial insemination can also be performed using frozen semen, which can increase the conception rate. Before insemination, each female rabbit was intramuscularly injected with 50-100 units of chorionic gonadotropin. 4 to 6 hours after injection, insemination, insemination volume of 0.3 to 0.5 ml.
Aphrodisiac is artificially aphrodisiac to a rabbit that is not estrus. Common methods are: drug aphrodisiac, provocative aphrodisiac, information aphrodisiac. The drug aphrodisiac can be injected intramuscularly in the female rabbit's femoral muscle 50-100 units of chorionic gonadotropin, and 4 to 6 hours after the injection for breeding. Provocative aphrodisiac is to put the female rabbit into the male rabbit cage to allow the male rabbit to chase and climb, stimulate the female rabbits to heat, generally aphrodisiac in the morning and mating in the afternoon. Information aphrodisiac is the female rabbit caught in a male rabbit cage, any male rabbit chase after the climb, after a period of time, the male rabbit is taken out, so that the female rabbit in the cage overnight. As the female rabbit fully accepted the male rabbit's breath in the male rabbit cage, on the second day the female rabbit will have estrus, and the breeding can be performed at this time.
