Management of pregnant rabbits
Before and after mating to the 15th day of pregnancy, female rabbits were fed with limited or supplementary feeding respectively according to the body condition of female rabbits to prevent overfattening from being unfavorable to production. The emaciated female rabbits should seize the opportunity to strengthen feeding and urge them to regain fat as soon as possible so as to lay a solid foundation for feeding young rabbits. Female rabbits during the fifteenth day of pregnancy and lactation should adopt free feeding to meet the rapid growth of fetuses and young rabbits, develop and prevent the occurrence of milk hanging accidents. The key point of this period is that the feed should be as full as possible so that the female rabbit can have enough to eat.
Secondly, do a good job of delivery, provide enough drinking water, and determine and adjust the number of young rabbits according to the needs of production, breeding level, feed formula, the largest litter size should not exceed the nipple number of female rabbits, and rabbits that cannot be fostered should be abandoned on the day of giving birth. Both pregnant and lactating rabbits shall not use moldy feed, and it is uncertain whether harmful drugs shall not be used in pregnant rabbits, otherwise, it will easily lead to miscarriage and death. The death of young rabbits caused by low temperature in winter can not be ignored, which should be paid attention to. Some pregnant rabbits have no signs before birth, and postpartum feathering should be eliminated.
