长毛兔产毛量受到季节因素的显著影响,导致一年中各养毛期产毛量迥异,因而单次剪毛量×5的方法并不能简单地应用于长毛兔年产毛量的估计。该研究经过两年连续测定两批试验兔各5次养毛期剪毛量,结果表明:公母长毛兔1—3月份剪毛,单次剪毛量较高,4—7月份剪毛,产毛量逐渐下降,8—9月份剪毛,产毛最少,而后逐月较快回升,12月恢复到1月份剪毛量,全年各月份剪毛产量呈偏V字型,体重变化与产毛量相似;1—3月份和12月份剪毛产毛量(×5)与实际年产毛量的换算系数在1以下,4—7月份剪毛换算系数为1左右,而8月份和9月份剪毛换算系数远高于1,全年1—12月份换算系数呈偏钟罩型。研究揭示了长毛兔全年5次养毛期剪毛量的变化规律,获得了不同月份剪毛量估测年产毛量与实际年产毛量的换算系数,结果可为长毛兔生产和科学研究提供参考。
The gross yield of long-haired rabbits is significantly affected by the seasonal factors, resulting in very different amounts of wool produced during each year of raising furrows. Therefore, the method of single-shearing amount × 5 can not simply be applied to the estimation of the annual wool yield of long-haired rabbits . The study after two consecutive years of two groups of test rabbits each 5 hairpinning hair cut the results showed that: male and female long-haired rabbits from January to March shearing, a single high-sheared, shearing from April to July, wool yield Gradually declined. From September to September, shearing was the least, and wool production was at least monthly. She picked up rapidly from month to month in December. Shear volume was recovered in January and monthly. Shear yield was V-shaped in each month of the year. The change of body weight was similar to that of wool production. - March and December, the gross yield (× 5) and the actual annual output of wool conversion factor below 1, April-July shear conversion factor of about 1, while in August and September shearing conversion factor is much higher than 1, the conversion factor from January to December of the year is partial clock cover type. The results showed that the change rule of the hair length of the five-week-long-haired rabbit during the raising period was obtained, and the conversion coefficient of the estimated annual output of the annual yield of wool-bearing rabbits and actual annual output of the wool was obtained. The results could be provided for the production and scientific research reference.
