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 good rabbits, we can adopt the following technical measures: (1) Improve the environment and manage it carefully. After entering the autumn, ventilation in the rabbit house is enhanced to 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, it generally takes 45 days to recover, and female rabbits can be restored in 7 days or so heat. Once the temperature drops, you can resume breeding, which will help maintain male rabbits with good semen, at least 1-2 litters. (B) adjust the feed, speed up the recovery. In the fall, sooner or later, cool, rabbits have increased appetite. Mixed concentrates should be fed in the morning and evening. Night concentrates should account for 2/3 of the diet, and provide clean drinking water. At other times, high quality green roughage should be fed. After re-feeding, feed more protein-rich feeds such as soybeans, bran, fish meal, germinated barley, silkworm meal, etc., and 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 2% bone meal or stone powder. (c) to seize breeding breeding. After the fall, it is necessary to grasp the estrus period of the female rabbit (the female rabbit is estrus 7 to 15 days, each lasting 3-4 days), and timely breeding. When the female rabbit is in estrus, it shows redness and swelling of the genitals, and some vaginas will flow out of the mucus, and they will make a squeak and will run around. At this time, it is necessary to grasp the timing of mating with "pink early, purple later, and scarlet time", that is, when the female ovary is in a large red color, it is most appropriate to breed, so that the rate of conception can be improved, and double match can be achieved (same as the same period of estrus. Two male rabbits will be bred or separated from the other rabbit by eight hours. (D) artificial aspiration. Common methods are: drug aphrodisiac, provocative aphrodisiac, information aphrodisiac. Drug aphrodisiac can be injected intramuscular 50 to 100 units of chorionic gonadotropin in the medial fetus, and 4 to 6 hours post-injection. 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 chasing cross-climbing, after a period of time, the male rabbit was taken out, so that the female rabbit stayed overnight in the cage. 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. (five) use of frozen semen early mating. High temperature has a greater impact on sexual performance of male rabbits, and natural mating results in lower fertility rates. 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 0.3-0.5 ml. (six) shorten the period of breast-feeding, feed supplements in advance. The lactation period of puppies should be limited to 35 days, which is conducive to the recovery of the female rabbit's physical strength and winterization. The puppies began to train for food within 15 days of age and were fed easily digestible, nutrient-rich feeds such as young grasses, leaves, etc., and were fed by methods of eating small meals. Practice has proved that early feeding of puppies 35 days of age can basically adapt to feed intake, and good growth and development. If the female rabbit has too many litters, the young rabbits may be fostered or artificially breast-fed to ensure that the pups can wean the eggs in time and increase the number of fetuses born throughout the year. (seven) to strengthen the prevention and treatment of rabbit diseases. There is a large temperature difference between day and night in autumn, and the activity of pathogenic microorganisms is very strong. After a hot summer, the rabbits have a marked decline in their physical constitution and are susceptible to the disease. In particular, there is a high incidence of diseases such as rabbit lice, pasterellosis, coccidiosis, and colds. Add oxytetracycline 100-200 mg/complex or compound enemy bacteria net 40-50 mg/kg in feed and add garlic or onion to prevent disease. Chlorophenyl hydrazine can be added to the feed during the rainy season, and 2.5 mg per kilogram of body weight can be used to prevent coccidiosis for 45 days. For rabbits suffering from coccidiosis, Chinese medicine can be used: 25 grams of Pulsatilla, 15 grams of purple altar, 10 grams of Changshan, 10 grams of woody, 15 grams of Chenxiangyuan, and 15 grams of red vine. Water decoction or stir in feed Hey. In addition, it is necessary to frequently change the floor of the rabbit cage, often cleaning the grass roots and faeces at the bottom of the cage with bamboo ray. After the utensils and utensils are used, they must be washed, exposed to sunlight, disinfected, and keep the rabbit house clean. If diseased rabbits are found, they must be isolated in time to avoid infection. Before entering the winter season, it is necessary to pay attention to strengthening the management of young rabbits, and prevent the occurrence of colds, pneumonia and other diseases, and should be prevented as soon as possible, in advance for vaccination.
