(一)推廣伏種，精細(xì)選種，實(shí)行雜交改良在我國(guó)飼養(yǎng)的長(zhǎng)毛兔中，以德系安哥拉免產(chǎn)毛量更高，法系安哥拉兔居中，英系和中系安哥拉較低。近些年我國(guó)培育的唐行系、皖系長(zhǎng)毛兔產(chǎn)毛量和兔毛質(zhì)量均較高。在推廣品種的同時(shí)，要不斷選育這些品種，以避免后代退化。
(a) V promotion, fine selection, implementation of crossbreeding in China bred Angora rabbit, the German Angola free wool yield the highest law in Angola center, British and Chinese in Angola is relatively low. In recent years China's cultivation of Tang line, Wanxi Angora rabbit wool and rabbit hair are high quality. At the same time, to promote the quality of varieties, we must continue to breed these varieties, in order to avoid future generations of degradation.
(二)保證營(yíng)養(yǎng)供應(yīng)，提供全價(jià)日糧由于硫是兔毛的組成元素之一，對(duì)兔毛的產(chǎn)量和彈性、強(qiáng)度等紡織性能有重要影響。因此，在配合日糧時(shí)要注意含硫氨基酸－－胱氨酸的添加。兔毛的角蛋白是由多種氨基酸組成的，所以必須供給多量的蛋白質(zhì)。理想的毛兔日糧中，蛋白質(zhì)應(yīng)占17％左右，含硫氨基酸含量不低于0.6％。
(two) ensure the supply of nutrients to provide complete diets because the sulfur is one of the constituent elements of hair, hair has an important effect on the yield and elasticity, strength of textile performance. Therefore, it should be paid attention to the addition of sulfur amino acid and cysteine in the diet. Keratin hair is composed of a variety of amino acids, so we must supply large amounts of protein. The ideal Maotu dietary protein should be accounted for about 17%, the content of sulfur amino acid content of not less than 0.6%.
(三)搞好兔籠設(shè)備，精心管理長(zhǎng)毛兔的管理，強(qiáng)調(diào)籠舍設(shè)備要配套。斷奶后的免要求一兔一籠，籠舍地面要勤打掃、勤。喂食要定時(shí)定量，注意飲水量。其次，要嚴(yán)防打架和受傷。
(three) to hutch equipment, careful management of Angora rabbit management, emphasize the cage equipment to complete. After weaning the requirements of a rabbit cage, the cage ground to ground cleaning, ground disinfection. Feeding should be quantitative, pay attention to the amount of water. Secondly, to prevent and fight injured.
(四)促進(jìn)毛兔皮膚、毛囊發(fā)育，增加被毛密度兔皮初生毛囊在胎兒后期(20—26天)開(kāi)始發(fā)育，次生毛囊在胎兒出生后開(kāi)始發(fā)育。因此，在母兔妊娠后期和哺乳期應(yīng)加強(qiáng)營(yíng)養(yǎng)。
(four) promote rabbit skin, hair follicle, hair follicle density increased by newborn rabbit in the later period of the fetus (20 - 26 days) the development of secondary follicle in fetal development after birth. Therefore, nutrition should be strengthened in the later stage of pregnancy and lactation.
(五)產(chǎn)毛化母兔比公免產(chǎn)毛量高5％—20％。群體產(chǎn)毛越高，差異越大。繁殖母兔由配種前剪毛、短間隔剪毛、產(chǎn)前自身拉毛等，可使30％左右的絨毛失去紡織價(jià)值。去勢(shì)可使公兔產(chǎn)毛量提高，但不應(yīng)過(guò)早去勢(shì)。為此，可施行繁殖、產(chǎn)毛化。
(five) wool professional female rabbits than the male free high wool yield 5% - 20%. The higher the population is, the greater the difference is. Reproductive female rabbits by mating prenatal short interval shearing, shearing, the galling, can make about 30% of the lost value of textile fluff. Castration can increase the yield of male rabbits, but it should not be premature. To this end, the implementation of breeding, wool production specialization.
(六)講求方法。合理采毛要根據(jù)季節(jié)和兔的生理階段等具體情況合理安排剪毛和拔毛。冬季以拔毛為主，夏季以剪毛為主，拔毛適用于被毛密度大的品種和個(gè)體，孕兔、哺乳母兔、配種期公兔及幼兔不宜拔。
(six) stress method. Reasonable hair collection according to the season and rabbit physiological stage specific conditions such as reasonable arrangement of shearing and plucking. In winter plucking, summer to shearing, plucking for wool density and the variety of individual pregnant rabbits, lactation mother rabbit, rabbit and rabbit breeding period should not be pulled out.
(七)適時(shí)采毛按季節(jié)氣候的變化在拔毛前采毛。幼兔出生后42天開(kāi)始換毛，持續(xù)70天，故出生后50天內(nèi)采毛。成年兔換毛，春季一般在3—4月?lián)Q掉冬毛長(zhǎng)夏毛；秋季一般8—9月，脫掉夏毛，換上冬毛。為此，采毛的時(shí)間應(yīng)安排在換毛前。此外，建立合理的兔群年齡結(jié)構(gòu)、人工催毛、保持適宜的環(huán)境溫度、根治毛兔疥癬病、杜絕脫毛癥等也是重要的措施。
(seven) according to the seasonal climate change, the seasonal climate change. Some young rabbits began 42 days after birth, lasting 70 days, 50 days after the birth of the inner hair collection. Adult rabbits molt, usually in the spring of 3 April to replace the winter hair long hair in summer; autumn is generally from 8 to September, the summer off hair, put on the winter hair. To this end, the timing of the hair should be arranged in front of the. In addition, the establishment of reasonable rabbit population age structure, artificial wool, urged to maintain proper temperature, radical Maotu scabies and eliminate alopecia are also important measures.
