断奶是兔兔幼兔生理的重要转折,管理不善,容易引起疾病甚死亡。兔兔幼兔的死亡大部分发生在断奶3周内,特别是1周到-~2周,其主要原因是断奶不当。正确的断奶方法应根据兔兔的体质健壮状况,如果全窝子兔发育均匀,体质健壮,可一次性断奶,即在同内将母子分开。如果全窝子兔发育不均匀,应该采用分期断奶法,即先断体质健壮的兔兔,让体质弱的子兔多哺乳几天,视情况酌情断奶。无论采用哪一种断奶方式,都应坚持断奶不离窝的原则,使兔兔在原来的笼内生活,做到饲料、环境、管理三不变,尽量减少应激并发症。
Weaning is an important turning point in the physiology of young rabbits, poor management, easy to cause disease and even death. Most of the deaths of young rabbits occurred within 3 weeks of weaning, especially from 1 week to 2 weeks. The main reason was improper weaning. The correct weaning method should be based on the healthy condition of the rabbits. If the rabbits in the whole nest are well developed and healthy, they can be weaned at one time, that is to say, the mother and the son can be separated in the same day. If the development of the rabbits in the whole nest is uneven, the method of weaning by stages should be adopted, that is, the rabbits with strong constitution should be weaned first, and the rabbits with weak constitution should be lactated for a few more days, depending on the situation. No matter what kind of weaning method is adopted, we should adhere to the principle of weaning without leaving the nest, so that the rabbits can live in the original cage, keep the feed, environment and management unchanged, and minimize the stress complications.
精料包括玉米、大麦、小麦、高粱、麸皮、细米糠等以能量为主的粮食类饲料原料和豆粕、菜子饼、鱼粉、蚕蛹、血粉等蛋白质含量高的饲料原料。它们的共同特点是粗纤维含量低、水分含量低、营养价值高。要想提高肉兔的增重率,让毛兔多产毛、獭兔多产高等级皮,都离不开精料。
The concentrate includes corn, barley, wheat, sorghum, bran, fine rice bran and other energy based food feed materials, and soybean meal, rapeseed cake, fish meal, silkworm chrysalis, blood meal and other feed materials with high protein content. Their common characteristics are low crude fiber content, low moisture content and high nutritional value. If we want to improve the weight gain rate of meat rabbit, let the wool rabbit produce more hair, Rex Rabbit produce more high-grade skin, we can't do without concentrate.
兔兔利用精料的原则是,要按不同种类兔的营养需要,根据不同地区、不同兔场的饲料来源及饲养条件,因地制宜地实行精料、粗料、青料的合理搭配饲喂。如果是自己加工配合饲料、但缺乏青饲料的兔场,其精、粗料比例一般为7:3;青料较丰富的兔场,精、粗料的比例可改为8:2。注意多喂全价饲料,少喂浓缩饲料。自己配制饲料时要尽量少用或不用鱼粉,如果要用,必 须保证鱼粉的质量。
The principle of using concentrate for rabbits is that according to the nutritional needs of different kinds of rabbits, according to the feed sources and feeding conditions of different regions and different rabbit farms, the reasonable combination of concentrate, roughage and green feed should be carried out according to local conditions. The ratio of concentrate to roughage is generally 7:3 for the rabbit farm which processes compound feed but lacks green feed; In the rabbit farm with rich green materials, the ratio of fine and coarse materials can be changed to 8:2. Pay attention to feed more full price feed and less concentrated feed. When you prepare your own feed, you should use less or no fish meal. If you want to use fish meal, you must ensure the quality of fish meal.
