斷奶是
長毛兔幼兔生理的重要轉折，管理不善，極易引起疾病甚死亡。下面小編就給大家詳細的講解一下長毛幼兔斷奶時機把控的問題！
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!
長毛兔種兔幼兔的死亡大部分發(fā)生在斷奶3周內(nèi)，特別是第1周-~2周，其主要原因是斷奶不當。正確的斷奶方法應根據(jù)長毛兔種兔的體質(zhì)健壯狀況，如果全窩子兔發(fā)育均勻，體質(zhì)健壯，可一次性斷奶，即在同內(nèi)將母子分開。如果全窩子兔發(fā)育不均勻，應該采用分期斷奶法，即先斷體質(zhì)健壯的長毛兔種兔，讓體質(zhì)弱的子兔多哺乳幾天，視情況酌情斷奶。無論采用哪一種斷奶方式，都應堅持斷奶不離窩的原則，使長毛兔種兔在原來的籠內(nèi)生活，做到飼料、環(huán)境、管理三不變，盡量減少應激并發(fā)癥。
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、大麥、小麥、高粱、麩皮、細米糠等以能量為主的糧食類飼料原料和豆粕、菜子餅、魚粉、蠶蛹、血粉等蛋白質(zhì)含量高的飼料原料。它們的共同特點是粗纖維含量低、水分含量低、營養(yǎng)價值高。要想提高肉兔的增重率，讓毛兔多產(chǎn)毛、獺兔多產(chǎn)高等級皮，都離不開精料。
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.
長毛兔種兔利用精料的原則是，要按不同種類兔的營養(yǎng)需要，根據(jù)不同地區(qū)、不同兔場的飼料來源及飼養(yǎng)條件，因地制宜地實行精料、粗料、青料的合理搭配飼喂。如果是自己加工配合飼料、但缺乏青飼料的兔場，其精、粗料比例一般為7:3；青料較豐富的兔場，精、粗料的比例可改為8:2。注意多喂全價飼料，少喂?jié)饪s飼料。自己配制飼料時要盡量少用或不用魚粉，如果要用，必須保證魚粉的質(zhì)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.
