1, early production and timely breeding. The first mating age of the female rabbit is about 5.5 months of age, and the weight is about 2.75 kg. If the age of first birth, weight is too high, too heavy, the difficult birth rate of the first-born female rabbits tends to increase.
2, female rabbits provide appropriate nutrition during pregnancy. Some rabbit farmers have a misunderstanding: When they think that a rabbit is pregnant, the more it is fed, the better, and the higher the feed nutrition, the better. Actually, according to the Rabbit Breeding Research Laboratory of the Institute of Animal Husbandry and Veterinary Medicine, Shanxi Academy of Agricultural "Premix" research found that for pregnant females, feed nutrition levels are low energy (10.47 MJ/kg), medium protein levels (17.5% crude protein), limiting rearing (170 g/day) In the method, the litter size was highest and no dystocia was found. With the use of high-energy, high-protein nutrition, the number of litters decreased, and the incidence of childbirth disorders was high. Because the high-energy, high-protein causes the fetus to be too large, occupy the uterine space, cause the stillbirth to increase, at the same time the fetus is too big, the risk of having difficulty increasing is increased. However, if the confinement of the pregnant female rabbit is too weak, it may easily cause dystocia due to insufficient productivity. Therefore, in the production according to the female rabbit's body condition, adjust the amount of feeding, maintain 7-80% of sensation on it, and after the delivery and then gradually increase the amount of feeding.
3, fetal position is not correct. Dystocia may also be caused by fetal position, fetal orientation, and malposition.
