        種兔的幼兔什么時(shí)候斷奶比較合適?

        發(fā)布日期:2021-06-28 來源:http://m.jinrimeigu.cn 發(fā)布人:admin

        斷奶是兔兔幼兔生理的重要轉(zhuǎn)折,管理不善,容易引起疾病甚死亡。兔兔幼兔的死亡大部分發(fā)生在斷奶3周內(nèi),特別是1周到-~2周,其主要原因是斷奶不當(dāng)。正確的斷奶方法應(yīng)根據(jù)兔兔的體質(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(yīng)該采用分期斷奶法,即先斷體質(zhì)健壯的兔兔,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(yīng)堅(jiān)持?jǐn)嗄滩浑x窩的原則,使兔兔在原來的籠內(nèi)生活,做到飼料、環(huán)境、管理三不變,盡量減少應(yīng)激并發(fā)癥。
        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.
                       長(zhǎng)毛兔兔毛
        精料包括玉米、大麥、小麥、高粱、麩皮、細(xì)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(diǎn)是粗纖維含量低、水分含量低、營(yíng)養(yǎng)價(jià)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(jí)皮,都離不開精料。
        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.
        兔兔利用精料的原則是,要按不同種類兔的營(yíng)養(yǎng)需要,根據(jù)不同地區(qū)、不同兔場(chǎng)的飼料來源及飼養(yǎng)條件,因地制宜地實(shí)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(chǎng),其精、粗料比例一般為7:3;青料較豐富的兔場(chǎng),精、粗料的比例可改為8:2。注意多喂全價(jià)飼料,少喂?jié)饪s飼料。自己配制飼料時(shí)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 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.
