In aquaculture production, the phenomenon of feasting on female rabbits occurs from time to time, but the occurrence rate is high in winter. This is due to the lack of green and green feed in winter, incomplete nutrition, and frightened female rabbits during delivery. The farmers need to comprehensively analyze the causes and adopt appropriate measures. Measures. First, feed nutrition is not complete Female rabbit feed lacks vitamins and minerals, lack of protein, especially female rabbits lack of supply of green feed before and after delivery, a single feed, such as lack of a variety of nutrients for a long time can cause the female rabbit to appear eating phenomenon. Preventive measures: Female rabbits must provide nutritious full-price feed during the winter season, and the protein content must be met when the feed is prepared, and it should be maintained at around 17%. Multivitamins, trace elements, and minerals should be properly added, and if necessary, add 4 % of premix. And feed green feed or juicy feed, such as carrots, white radish, vegetable leaves, a small amount of cabbage leaves, etc., to supplement the deficiency of vitamins. Second, the female rabbit is scared by childbirth When the female rabbit was delivered, it was panic-stricken and disturbed by the outside world to interrupt the farrowing and tamper with stepping to death or eating the puppies in the birth box. In particular, various abnormal sounds suddenly occurred and were strongly stimulated by the outside world. Preventive measures: When the female rabbits give birth, they must keep the surrounding environment quiet, prevent the occurrence of abnormal sounds, reduce various stress responses and influences, prevent dogs and cats from entering, and cause the female rabbits to panic and startle. Do not send female rabbits during childbirth. Watch and wait until after birth to jump out of the birthplace to dispose of dirt and keep the female rabbit safe and normal. Third, produce nest, produce boxes have smell The sense of smell of rabbits is relatively sensitive. If there are odors in the litters and produce boxes, it will make them feel sick and not dare to give birth to them or force them to go far if there is no way to do so, but they will also go out of the litter box. The pups are killed or eaten. If the postpartum does not handle the dirt, especially if the dead rabbit has stinked, the female rabbit is reluctant to enter the nest to feed the pups. Preventive measures: The mother rabbits were disinfected about 5 days before giving birth, and they were placed in the sunlight after being disinfected, and then covered with clean mat grass. However, they should prevent the grass from becoming moldy and spoil. When the female rabbits view the puppies after giving birth, Do not touch the puppies with a stench of the peculiar smell. It is best to treat the puppies with feces and urine and then treat the puppies to prevent the peculiar smell from causing the female rabbits to eat puppies. Fourth, postpartum lack of water When the female rabbit is farrowing, eating the placenta while giving birth will cause thirsty phenomenon. When the female rabbit gives birth, it will jump out of the birth box and find water to drink. If there is not enough drinking water at this time, the female rabbit will have difficulty in thirst. In the case of forbearance, he ran back to the crate to eat the pups. Preventive measures: Before and after giving birth, the female rabbit should provide sufficient drinking water, and the sugar and salt water should be better. At the same time, green feed or multiple juice feed should be provided. V. Postpartum lactation Due to lack of green feed, female rabbits lack milk after delivery, and the young rabbits do not eat enough. The hungry puppies compete for nipples when they are sucking, and the female rabbit refuses to breastfeed or even bite the pups due to pain. Preventive measures: to strengthen nutrition, female pre- and post-natal feeding more succulent feed or postpartum drinking brown sugar water, soy milk, in order to increase the amount of milk, the female rabbits with little or no napped hairs should be artificially assisted to pull hairs, pulling hairs can stimulate female rabbits Breast development, promote milk secretion. The female rabbits with damaged nipples should be promptly treated to prevent infection and secondary to mastitis. Care should be taken to breed the pups born to the severely lactating female rabbits. If the second child is to be eliminated when it is severely deficient, it cannot be used for seeding. Sixth, the first female rabbit or mother is not strong A few female rabbits, especially first-born females, have poor maternal and lactation levels, and they eat together with puppies when they eat the placenta due to pain. Precautionary measures: When selecting females to be selected, select offspring that have good maternity, farrowing, laziness, and lactation. Female hindquarters should be well-developed, especially when females are examined during mating. However, it is not possible to keep the small and inflamed species. For the mother is not strong can take the separation of mothers, artificial feeding regularly feeding method. The female rabbits who have both litters should be eliminated. VII. Improper fostering methods When foster rabbits are placed, due to large time gaps or differences in individual fleas and odors, the foster females are disgusted with the foster rabbits and either eat or bite the fleas after delivery. Preventive measures: The foster rabbits should not be more than two days in time. The individuals must be basically the same and cannot be too far apart from each other. Doing a good job of putting the foster rabbits on the rabbits with the feces and urine of the foster female rabbit makes the smell the same. The female rabbit can not distinguish the foster rabbits, but can also remove the baby rabbits and then place the foster rabbits in the box for half a day. The female rabbits can not distinguish the foster rabbits. Eight, female rabbits have food As the female rabbits are not managed well before delivery, the protein in the feed is insufficient or lacks certain substances, and before the farrowing, the concentrate or green feed is lacking. The female rabbits are hungry at the time of delivery, and when they are delivered, the rabbits are eaten as placentas. When the second child is delivered, it will also eat the puppies and it will form a habit of eating puppies. Preventive measures: When the female rabbits give birth, they must be taken care of. After giving birth, the rabbits are taken away immediately. The mother rabbits are isolated and reared, and the female rabbits are eliminated. 9. Man-made eating In particular, the first-time raiser, when the female rabbit is giving birth, watches or grabs the rabbit by hand, so that the female rabbit is in a state of panic and eats the baby rabbit. Preventive measures: Do not watch female rabbits during delivery, and do not touch the rabbits by hand. Keep quiet and examine after delivery. Medton Medical , https://www.medton.cn
