幼兔育肥是指仔兔断奶后即开始催肥,2.5~3月龄体重达到2~2.5千克时即可出售。此阶段幼兔生长发育快,又由于刚断奶,消化能力差,抗病力弱,适应性差,其主要技术环节为:
Fattening refers to the fattening of young rabbits after weaning, which can be sold when their weight reaches 2-2.5 kg at the age of 2.5-3 months. At this stage, the growth and development of young rabbits are fast, and due to the just weaning, the digestion ability is poor, the disease resistance is weak, and the adaptability is poor
一、编群分组催肥
1、 Group and group fattening
按幼兔体质强弱、日龄大小,将断奶日期接近或生长发育差异不大的幼兔编群分组,每组20~50只,每1~1.5只;笼养时每笼以3~4只为宜,太多会拥挤而影响发育。
According to the physical strength and age of the young rabbits, the young rabbits with close weaning date or little difference in growth and development were grouped into groups, 20-50 rabbits in each group, 1-1.5 rabbits per square meter; 3-4 rabbits per cage were suitable for cage, too many would affect the development.
二、三阶段育肥法
2、 Three stage fattening method
即初始阶段以精料为主,青粗料为辅(快速生长,拉大骨架);二阶段以青粗料为主,精料为辅(加大采食量,锻炼消化机能);第三阶段以精料为主,青粗料为辅(目的是快速催肥)。
That is to say, in the initial stage, concentrate is the main material, supplemented by green and coarse materials (rapid growth, enlarging the skeleton); in the second stage, concentrate is the main material, supplemented by fine materials (increasing feed intake, exercising digestive function); in the third stage, concentrate is the main material, supplemented by green and coarse materials (the purpose is to quickly fatten).
三、科学搭配饲料
3、 Scientific collocation of feed
喂给幼兔的饲料必须容积小,营养价值高,易消化,而且粗纤维必须达到要求。比较适宜的肥育饲料有玉米、燕麦、大麦、麸皮、豆饼、马铃薯、甘薯等。参考配方为:肥育前期为青干草粉70%、玉米粉(面)11%、豆饼5%,麸皮10%、骨粉3%、食盐1%;肥育后期为青干草粉10%、玉米粉(面)80%、麸皮6%、骨粉3%、食盐1%。要多喂些营养价值高、易消化的精饲料及多汁的青饲料,如豆秧、蒲公英等,适当补充一些动物性饲料。饲料一定要清洁、新鲜,饲喂量随着月龄的增长逐渐增加,防止喂料突然增加或突然改变。
The feed for young rabbits must be small in volume, high in nutritional value, easy to digest, and the crude fiber must meet the requirements. Corn, oat, barley, wheat bran, soybean cake, potato, sweet potato and so on are suitable for fattening. The reference formula was as follows: 70% green hay powder, 11% corn powder (flour), 5% soybean cake, 10% bran, 3% bone powder and 1% salt in the early stage of fattening; 10% green hay powder, 80% corn powder (flour), 6% bran, 3% bone powder and 1% salt in the late stage of fattening. We should feed more high nutritional value, digestible concentrate feed and juicy green feed, such as bean seedling, dandelion, etc., and appropriately supplement some animal feed. The feed must be clean and fresh, and the feeding amount increases gradually with the increase of age, so as to prevent the sudden increase or change of feed.
四、做到少喂多餐
4、 Feed less and eat more
日喂量以基本吃饱为宜,饲喂时应少喂多餐,每日喂4次即早、中、晚、22时(晚上10点);饮水以自动饮水器或自流瓶式为宜;环境温度以5~25℃为宜。前期要增加光照,后期(尤其是宰前15天)光照要暗。
The daily feeding amount should be basically full, and the feeding time should be less and more meals, four times a day, i.e. early, middle, late and 22 o'clock (10 p.m.); the drinking water should be in the form of automatic water dispenser or self flowing bottle; the environmental temperature should be 5 ~ 25 ℃. Light should be increased in the early stage and dark in the late stage (especially 15 days before slaughter).
五、注意环境控制
5、 Pay attention to environmental control
幼兔笼舍要放置在向阳、背风、干燥的地方,使幼兔多接受阳光照射,但不易放强光下照射。冬季室内饲养,温度应保持在5~10℃。同时要搞好室内及笼舍卫生,兔舍每天必须坚持打扫,垫草要勤换,并保持干燥。
The young rabbit cage should be placed in a sunny, leeward and dry place, so that the young rabbit can receive more sunlight, but it is not easy to be exposed to strong light. In winter, the temperature should be kept at 5 ~ 10 ℃. At the same time to do a good job in indoor and cage hygiene, rabbit house must adhere to cleaning every day, bedding grass to change frequently, and keep dry.
夏季气温高,兔舍外应搭凉棚或种植葡萄、丝瓜、南瓜等藤蔓类植物遮阳,并采取开启门窗、泼水、喷雾、开电风扇等方法降温。
The summer temperature is high. Outside the rabbit house, shading should be carried out by planting a greenhouse or planting vines such as grapes, towel gourd and pumpkin.
保持兔舍清洁干燥,相对湿度不超过60%;过湿时撒碎干草、沙土或生石灰、草木灰等,吸湿、。笼养兔,每周早晚凉爽时放出2~3次进行运动,但时间不宜太长(须由专人看管)。夏季可在早晚天气凉爽时喂饲料,供足清洁卫生的饮水,并在水中加入1%~1.5%的食盐。
Keep the rabbit house clean and dry, the relative humidity is not more than 60%; when it is too wet, sprinkle crushed hay, sand or quicklime, plant ash, etc., absorb moisture, disinfect and sterilize. Caged rabbits should be released 2-3 times a week when it is cool in the morning and evening, but the time should not be too long. In summer, when the weather is cool in the morning and evening, the feed can be fed to provide enough clean drinking water, and 1% ~ 1.5% salt can be added into the water.
六、及早预防疾病
6、 Early prevention of disease
幼兔25~35日龄时,在饲料中添加敌菌净,每只兔每天喂给1毫克;36~45日龄时,在饲料中添加氯苯胍,每只兔每天喂两次,每次1片;60~70日龄时,每只颈部皮下注射兔瘟疫苗1.5毫升。要经常观察兔群的健康情况,发现病兔应及时进行隔离和。夏季要做好消灭鼠类、蚊蝇等工作,禁喂霉变草料,定期免疫接种兔瘟等疫苗,严防传染病的发生。
At the age of 25-35 days, each rabbit was fed with 1 mg of Dijunjing every day; at the age of 36-45 days, each rabbit was fed with 1 tablet of chlorphenformin twice a day; at the age of 60-70 days, each rabbit was subcutaneously injected with 1.5 ml of rabbit plague vaccine. It is necessary to observe the health of the rabbits and isolate and treat the sick rabbits in time. In summer, we should do a good job in eliminating rodents, mosquitoes and flies, forbid feeding moldy grass, and regularly vaccinate against rabbit plague, so as to strictly prevent the occurrence of infectious diseases.
