1、秋末冬初,氣候變化異常,冷熱不均、溫差懸殊,加之光照時間日漸縮短,如果舍內小環(huán)境調控不當,種兔即會出現(xiàn)乏情或配種、受胎低的不良現(xiàn)象。因此,應視情況采取保溫防寒措施,使舍溫保持在15—25度范圍內,光照時間達12小時以上。如不夠應采取人工補光措施,使之環(huán)境適宜,促進種兔正常生育。
1, the late autumn and early winter, abnormal climate change, uneven, great temperature difference, and the illumination time is getting shorter, if the small environment in the shed control improperly, rabbit appears bad phenomenon anestrus or mating, pregnancy is low. Therefore, should inspect a circumstance to take measures to preserve heat, temperature maintained at 15 - 25 range, the illumination time of 12 hours or more. Such as the lack of measures should be taken to the artificial light, make suitable environment, promote the rabbit normal fertility.
    2、由于氣候的變化,加之又處于季節(jié)換毛時期,種兔機體熱能消耗增大,如果飼料蛋白及營養(yǎng)跟不上,會導致種兔體質衰弱也會影響配種和繁殖。因此,除飼料營養(yǎng),多樣配合外,其蛋白應達18%以上,尤其含硫氨基酸、胱氨酸等更不能缺少,以促進種兔體況早日恢復投入生產。

2, because of climate change, and their seasonal molt period, rabbit body heat consumption increases, if the feed protein and nutrition does not follow to go up, will lead to physical weakness will also affect the rabbit breeding and reproduction. Therefore, in addition to comprehensive nutrition, diversity combined with external, above the protein amounted to 18%, especially sulfur-containing amino acid, cystine more cannot lack, in order to promote the early resumption of put into production in rabbit body condition.
    3、個別種兔患有繁殖障礙癥,如公兔性欲差、配種力低;母兔不發(fā)情、屢配不孕等,則應根據不同情況分別對待。
3, individual rabbits with reproductive disorders, such as male rabbit sexual difference, breeding capacity is low; the female rabbit not estrus, sterility, it shall be treated according to different situations.
