(一)推广伏种,精细选种,实行杂交改良在我国饲养的长毛兔中,以德系安哥拉免产毛量更高,法系安哥拉兔居中,英系和中系安哥拉较低。近些年我国培育的唐行系、皖系长毛兔产毛量和兔毛质量均较高。在推广品种的同时,要不断选育这些品种,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)保证营养供应,提供全价日粮由于硫是兔毛的组成元素之一,对兔毛的产量和弹性、强度等纺织性能有重要影响。因此,在配合日粮时要注意含硫氨基酸--胱氨酸的添加。兔毛的角蛋白是由多种氨基酸组成的,所以必须供给多量的蛋白质。理想的毛兔日粮中,蛋白质应占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)搞好兔笼设备,精心管理长毛兔的管理,强调笼舍设备要配套。断奶后的免要求一兔一笼,笼舍地面要勤打扫、勤。喂食要定时定量,注意饮水量。其次,要严防打架和受伤。

(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)促进毛兔皮肤、毛囊发育,增加被毛密度兔皮初生毛囊在胎儿后期(20—26天)开始发育,次生毛囊在胎儿出生后开始发育。因此,在母兔妊娠后期和哺乳期应加强营养。

(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)产毛化母兔比公免产毛量高5%—20%。群体产毛越高,差异越大。繁殖母兔由配种前剪毛、短间隔剪毛、产前自身拉毛等,可使30%左右的绒毛失去纺织价值。去势可使公兔产毛量提高,但不应过早去势。为此,可施行繁殖、产毛化。

(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)讲求方法。合理采毛要根据季节和兔的生理阶段等具体情况合理安排剪毛和拔毛。冬季以拔毛为主,夏季以剪毛为主,拔毛适用于被毛密度大的品种和个体,孕兔、哺乳母兔、配种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)适时采毛按季节气候的变化在拔毛前采毛。幼兔出生后42天开始换毛,持续70天,故出生后50天内采毛。成年兔换毛,春季一般在3—4月换掉冬毛长夏毛;秋季一般8—9月,脱掉夏毛,换上冬毛。为此,采毛的时间应安排在换毛前。此外,建立合理的兔群年龄结构、人工催毛、保持适宜的环境温度、根治毛兔疥癣病、杜绝脱毛症等也是重要的措施。

(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.
