Preventive measures of dystocia in female rabbits

Timely breeding in the first birth

The first mating age of the female rabbit is about 5.5 months old and the weight is about 2.75 kg. If the age of first birth, weight is too high, overweight, the dystocia rate of female rabbits has an increasing trend, so it is necessary to prepare in advance.

Female rabbits should provide appropriate nutrition during pregnancy.

Some rabbit farmers have a misunderstanding: they think that once rabbits are pregnant, the more they feed, the better, and the higher the feed nutrition, the better. in fact, according to the rabbit breeding research room of the Institute of Animal Husbandry and Veterinary Medicine of Shanxi Academy of Agricultural Sciences, it was found that for pregnant female rabbits, the feed nutrition level was low energy (10.47 MJ / kg) and medium protein level (17.5% crude protein). Restricted feeding (170g / day), the litter size was the highest, and no dystocia was found. However, with the nutrition level of high energy and high protein, the litter size decreased and the incidence of delivery disorder was higher. Because of high energy and high protein, the fetus is too large, occupying uterine space, resulting in an increase in stillbirth, while the fetus is too large, the risk of dystocia increases. However, if the pregnant female rabbit is too weak, due to lack of productivity, it is also easy to cause dystocia. Therefore, in the production, according to the body condition of the female rabbit, adjust the feeding amount, keep 780% fat condition, and then gradually increase the feeding amount after delivery.

Incorrect fetal position

Dystocia may also be caused by abnormal fetal position, fetal orientation and fetal posture.
