        長毛兔食欲下降多半和溫度變化有關

        發布日期:2018-04-12 來源:http://www.bdf027.com 發布人:admin

          當環境溫度達32℃以上時,可引起長毛兔食欲下降、消化不良、性欲降低和繁殖困難等。尤其是長毛兔,在高溫季節即失去繁殖能力(公兔無精子或無活精子),出現所謂的夏季不育現象。

          When the ambient temperature is above 32 c, it can cause anorexia, dyspepsia, low sexual desire and reproductive difficulties. Especially the long haired rabbits lose their reproductive ability in the hot season.

          抓好飼料過渡隨著氣溫漸升,青草生長很快,青綠飼料幼嫩多汁,適口性好,家兔較貪食。開始飼喂青綠飼料時,宜先少后多,逐漸增加,切忌喂食過量而引起消化道疾病。青綠飼料要加以選擇,防止喂給有毒的青料。如斷腸草,苦參、白頭翁、天南星、生半夏、土大黃、夾竹桃、萬年青、玉米苗、高粱苗、蓖麻葉、菖蒲、菠菜等青料不能飼喂家兔,以免引起腹瀉。

          With the rising temperature, grass grows fast, green feed is young and juicy, palatability is good, and rabbits are more voracious. When feeding green feed, we should first increase less and increase more. We should avoid overfeeding and cause digestive tract diseases. Green fodder should be selected to prevent feeding poisonous green materials. Such as weangrass, Radix Sophorae, Radix Pulsatilla, Rhizoma Rhizoma, Rhizoma Pinelliae, rhubarb, oleander, evergreen, corn seedlings, sorghum seedlings, castor leaf, Acorus, spinach and other green materials can not be fed to rabbits, so as to avoid diarrhea.

          抓緊配種繁殖春季配種受胎率高,產仔數多,仔兔發育良好,體質健壯,成活率高。因此,有條件的兔場,每年3~4月份就應抓好配種工作,可采用頻密產仔法,連產2~3胎后,再調整恢復體力,所產仔兔秋后可上市銷售。

          Seize the spring breeding insemination rate, theaveragepregnancytimeis62 pups, growth is good, healthy body, high survival rate. Therefore, the condition of the rabbit farm, every year in 3~4 should do a good job of mating work, the use of the frequency density production method, even after the production of 2~3 births, then adjust to restore physical strength, the offspring of the offspring can be sold in autumn.

          若環境溫度持續在35℃以上長毛兔易發生中暑而死亡。相對而言,長毛兔能耐受低溫和寒冷,即使在嚴寒條件下,成年兔也能在開放式兔舍內越冬,但其繁殖受到影響,飼料消耗增加。

          If the ambient temperature lasts above 35 C, the long hair rabbit is liable to suffer heatstroke and die. In contrast, long haired rabbits can tolerate low temperature and cold. Even under cold conditions, adult rabbits can be safely overwintered in the open rabbit house, but their reproduction is affected and the consumption of feed is increased.
