断奶是
长毛兔幼兔生理的重要转折,管理不善,极易引起疾病甚死亡。下面小编就给大家详细的讲解一下长毛幼兔断奶时机把控的问题!
Weaning is an important turning point in the physiology of young rabbits of long-haired rabbit breed, which is easy to cause disease or even death due to poor management. The following edition will give you a detailed explanation of the weaning time control of long-haired young rabbits!
长毛兔种兔幼兔的死亡大部分发生在断奶3周内,特别是第1周-~2周,其主要原因是断奶不当。正确的断奶方法应根据长毛兔种兔的体质健壮状况,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,即先断体质健壮的长毛兔种兔,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,使长毛兔种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。
Most of the deaths of young rabbits of long-haired rabbits occurred within 3 weeks of weaning, especially in the first week - - 2 weeks. The main reason was improper weaning. Correct weaning methods should be based on the physique of rabbits. If the whole nest of rabbits is well developed and healthy, they can be weaned at one time, that is to say, mother and son can be separated in the same day. If the whole nest of rabbits does not develop evenly, weaning by stages should be adopted, that is, weaning healthy long-haired rabbits first, allowing weak rabbits to breast-feed for several days, as appropriate. Whichever weaning method is adopted, we should adhere to the principle of weaning without leaving the nest, so that the rabbit breed can live in the original cage, keep the feed, environment and management unchanged, and minimize 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。
Concentrates include corn, barley, wheat, sorghum, bran, fine rice bran and other energy-based food feed materials, as well as 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. In order to increase the weight gain rate of meat rabbit, to make wool rabbit produce more wool and Rex Rabbit produce more high-grade skin, all can not do without concentrate.
长毛兔种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 rabbit breeding 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 concentrate, crude feed and green feed should be reasonably mixed and fed according to local conditions. If it is a rabbit farm that manufactures its own formula feed but lacks green feed, the proportion of fine and coarse feed is generally 7:3; in a rabbit farm with rich green feed, the proportion of fine and coarse feed can be changed to 8:2. Attention should be paid to feeding more full-price feed and less concentrated feed. When you make your own feed, you should use fish meal as little as possible or not. If you want to use fish meal, you must ensure the quality of fish meal.
