The autumn weather is relatively dry, adequate feed and nutritious, and it is a good season for good rabbits. While grasping the autumn breed of thoroughbred rabbits, the following technical measures can be taken:
After improving the environment and carefully managing the autumn, the farmers should strengthen the ventilation of the rabbit house and keep the house clean and quiet. If three-layer cages are used, the male rabbits should be reared in the lowermost cages. Because the temperature in the lower rabbit cages is lower than the upper ones, the male rabbits can also be reared in a semi-basement. In particular, male rabbits in the hot season, the testicles reduced by 60%, even after the temperature dropped, generally 45 days to recover, and the female rabbits can be restored in about 7 days breeding, which is conducive to maintaining male rabbits have a good semen, at least Add 1 to 2 litter rabbits.
Adjust the feed to speed up the recovery of the early morning and late autumn cool, rabbits have enhanced appetite, mixed concentrates should be arranged in the morning and evening feeding, night fine feed should account for 2/3 of the diet, and provide clean drinking water, other time feed quality Green roughage. After re-feeding, feed more protein-rich feeds, such as soybeans, bran, fish meal, germinated barley, and silkworm cocoons. The mixed concentrate contains digestive energy of 2,900 kcal/kg, crude protein, 18%, crude fiber 10 % and add 1% salt and 2% bone meal or flour.
After grasping the breeding and breeding into the autumn, it is necessary to grasp the estrus period of the female rabbit (the female rabbit is exposed to heat for 7 to 15 days once, each time for 3 to 4 days), and timely breeding. When the female rabbit is in estrus, it shows redness and swelling of the genitals. Some vaginas will flow out of the mucus, and they will make a buzzing sound and will run around. At this time, it is necessary to grasp the timing of mating with “pink early, purple late, and big red”, that is, when the genitals of female rabbits are most suitable for breeding, they can increase the conception rate, and can also achieve dual allocation (the same estrus period is used successively. Two male rabbits will be bred or separated from the other rabbit by eight hours.
Artificial aphrodisiac commonly used 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 general 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.
The use of frozen semen early mating temperature has a greater impact on sexual performance of male rabbits, and the natural mating rate is low. After the beginning of autumn, artificial insemination using frozen semen 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.
