    怎樣提高兔毛的產(chǎn)量和質(zhì)量?

    1. 單籠飼養(yǎng)
    1. Single cage feeding
    籠養(yǎng)長毛兔有利于提高兔毛品質(zhì),毛色潔白,富有光澤,結(jié)塊毛少;圈養(yǎng)長毛兔,臀、腹部毛多呈尿黃色,兔毛強度、伸展度明顯下降,塊毛多,品質(zhì)差。
    Long hair rabbit in cage is beneficial to improve the quality of rabbit's hair, which is white, glossy and less caking hair; long hair rabbit in cage, whose buttock and abdomen hair are mostly urine yellow, whose strength and extension are obviously decreased, has more caking hair and poor quality.
    2. 加強營養(yǎng)
    2. Strengthen nutrition
    長毛兔除了生長、繁殖之外,還要長毛,必須保證充足的營養(yǎng)水平。據(jù)試驗,長毛兔營養(yǎng)充足,體質(zhì)健壯,不僅產(chǎn)毛量高,而且毛質(zhì)好;如營養(yǎng)不良,則兔毛干枯,塊毛多、品質(zhì)差。
    In addition to growth and reproduction, Angora rabbits also need to grow hair, which must ensure adequate nutritional level. According to the experiment, Angora rabbit has sufficient nutrition and strong physique. It not only has high wool production, but also has good wool quality. If it is malnourished, the rabbit's hair will be dry, with many pieces and poor quality.

    3. 加強管理
    3. Strengthen management
    環(huán)境衛(wèi)生對兔毛質(zhì)量影響很大。籠舍清潔、干燥,有利于減少污染毛量,提高兔毛品質(zhì)。此外,兔毛要勤梳理,防纏結(jié)。喂料時要防止草屑、飼料、灰塵污染被毛,影響兔毛品質(zhì)。
    Environmental hygiene has a great influence on the quality of rabbit hair. Clean and dry cages can reduce the amount of contaminated hair and improve the quality of rabbit hair. In addition, the rabbit hair should be combed frequently to prevent entanglement. When feeding, it is necessary to prevent grass chips, feed and dust from polluting the coat and affecting the quality of rabbit hair.
    4. 合理采毛
    4. Reasonable wool picking
    根據(jù)季節(jié)等具體情況,合理選擇剪毛和拔毛等采毛方法。一般夏季以剪毛為主,冬季以拔毛為主,這樣既可促進(jìn)兔毛生長,提高兔毛質(zhì)量,又有利于兔體健康。
    According to the season and other specific conditions, reasonable selection of shearing and plucking methods. Generally, shearing is the main method in summer and plucking is the main method in winter, which can not only promote the growth of rabbit hair, improve the quality of rabbit hair, but also benefit the health of rabbit.
    5. 兔毛保管
    5. Rabbit hair storage
    為提高兔毛品質(zhì),無論采用何種采毛方法,均應(yīng)實行分級采毛、分級收購、分級保管和分級調(diào)運的“四分”法。保存兔毛時,應(yīng)注意防潮、防蟲蛀、防纏結(jié)。
    In order to improve the quality of rabbit hair, no matter what kind of method is adopted, the "four points" method of grading collection, grading purchase, grading storage and grading transportation should be carried out. When preserving rabbit hair, attention should be paid to moisture-proof, moth proof and tangle proof.
