    發布日期:2020-05-14 來源:http://www.fshxt.net 發布人:admin

      目前我國長毛兔的生產效果比較好,但在長毛兔育種的發展中還存在一些問題,我們將了解國內長毛兔育種中存在的問題。
      At present, the production effect of Chinese Angora rabbit is good, but there are still some problems in the development of Angora rabbit breeding. We will understand the problems in the domestic Angora rabbit breeding.
      據有關部門統計,我國兔毛生產受到市場周期性經濟危機、國內管理失當、管理混亂等因素的影響,導致了生產的大起大落。這些生產的起伏對長毛兔產業的發展產生了很大的影響。

      According to the statistics of relevant departments, rabbit hair production in China is affected by the cyclical economic crisis in the international market, improper domestic management, management confusion and other factors, resulting in the ups and downs of production. These production fluctuations have a great impact on the development of the rabbit industry.
      雖然從國外引進了大量的長毛兔,但引進后長毛兔的育種工作做得并不好,許多品種的性能變差。而有些地區沒有根據當地的實際情況進行引種,引種盲目,且粗放養殖,養殖效率不高。
      Although a large number of Angora rabbits have been introduced from abroad, the breeding work of Angora rabbits is not well done after the introduction, and the performance of many varieties is poor. However, in some areas, the introduction is not based on the local actual situation, blind introduction, extensive cultivation and low efficiency of cultivation.
      我國兔毛產出量目前居世界首位,但總體而言,兔種群質量仍相對較大,單只兔的總產量不高。
      At present, the output of rabbit hair in China ranks first in the world, but generally speaking, the quality of rabbit population is still relatively large, and the total output of a single rabbit is not high.
