Key technical measures to improve the survival rate of young rabbits

First, arrange suitable reproductive strength, and always maintain the good condition of female rabbits in raising rabbits. It is not advisable to pursue excessively the number of litters per female rabbit. The species (lines), breeding and management conditions, and female rabbits should be considered. The specific situation of the lyrics and the field (household) should be reasonably arranged for appropriate breeding intensity. Otherwise, the survival rate of the young and young rabbits will be significantly reduced and “more students will die and more will die”. In general, there are only a few commercial meat rabbit production farms that are fed with full-priced pellet feed, automatic drinking water, and management measures. They can arrange for frequent breeding or semi-frequent breeding at 33-day (blood allocation) or 42-day breeding intervals. ~ 9 nests, the arrangement of blood allocation should be based on the condition of the female rabbit, in order to ensure the health of the female rabbits and good growth and development of pups, it is generally not appropriate to arrange blood allocation; feeding management of general or poor commercial meat Rabbit production sites (households) can visualize the health status of female rabbits and the development of puppies, and arrange females to breed 15 to 30 days after childbirth and breed 5 to 7 litters per year. Feeding and management conditions are better, there are rabbits rabbit breeds as long-haired rabbits and rabbits field, according to the specific circumstances arranged female 15 to 30 days postpartum breeding, breeding 5 to 7 nests; such as feeding and management conditions in general, and no Nanny rabbit rabbits and rabbits field, it is best to arrange maternal 30 to 45 days postpartum breeding. Second, a reasonable adjustment of the number of breast-feeding each female rabbit should not simply seek too much breast-feeding, it is necessary to ensure that lactating young rabbits can eat enough milk, physical strength, eliminate the occurrence of "stiff rabbits." Generally speaking, it is appropriate that each female rabbit fed with meat has 7 to 8 eggs per litter, while rabbits and rabbits have 4 to 5 females per litter. For too many puppies, if they are born with too little weight (less than 50 grams), or if there are too many male rabbits, they can be eliminated. For the extra well-developed puppies, look for female rabbits with similar maturities. Production practices have shown that it is unscientific for the number of mother rabbits to breastfeed. Third, the practice of isolation of breast-feeding mothers regularly breast-feeding every day, both to ensure that the female rabbits and puppies fully rested, the prevention of female rabbit mastitis and enteritis in rabbits is also very beneficial. When milk is insufficient or excessive, appropriate countermeasures should be taken. When milk is too thick, the amount of green and juicy feed should be increased and the amount of drinking water should be increased. When there is too much milk, the number of suckling rabbits can be appropriately increased. Female rabbits suffering from mastitis should immediately stop their breast-feeding. The rabbits should be fostered to other female rabbits. After the illness is cured, the rabbits will be re-breed and breed, and severe cases will be eliminated. Fourth, to strengthen the feeding and management of lactating female rabbits The key to feeding and management of lactating female rabbits is to ensure their healthy constitution and sufficient milk. In terms of feeding, adequate nutrients, especially protein nutrition, should be supplied. The content of digestive energy in lactating female rabbits' full-rate diet should be 11.51 to 12.13 MJ/kg, and crude protein should not be lower than 17% to 18%. In the feeding method using green feed as the basic feed supplemented with concentrate supplements, the crude protein content in concentrate supplements should be more than 20%, and the amount of concentrate supplements per bird per day is 125-200 grams. The amount of green and succulent feed is more than 1000 grams. In the diet of long-haired rabbits and rex rabbits, the addition of 3% to 5% of animal protein feed such as fish meal and silkworm cocoon can significantly increase the lactation of female rabbits. In terms of management, prevention of mastitis should be done mainly, and there are many causes of mastitis, mainly in the crates, cages, nails or other sharp objects on the breast; milk is insufficient, and the rabbits bite and break the nipple; Rabbits can't eat, the breasts swell and become inflamed; water shortages, lack of green and juicy feeds, and milky juices are too heavy, and appropriate precautions should be taken depending on the circumstances.
