(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*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。在推广优良品种的同时,要不断选育这些优良品种,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、勤消毒。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 |
