海狸色獭兔与白色獭兔杂交试验研究

The Study of Crossbreeding Between Beaver and White Rex Rabbit Line

为了探索用白色獭兔快速生产优质海狸色獭兔皮的繁育模式,开展了海狸色獭兔与白色獭兔杂交试验。配种组合为海狸色公兔×海狸色母兔(试验1组),白色公兔×白色母兔(试验2组)和海狸色公兔×白色母兔(试验3组)。3组后代进行生长发育和皮毛质量测定。结果表明:杂种的生长速度最高,料肉比最低;杂种海狸色较纯种海狸色獭兔的被毛密度、毛丛长度均高,枪毛比例在海狸色与白色獭兔之间;用海狸色公兔与白色母兔进行杂交是快速生产海狸色獭兔皮张的较佳繁育模式。

In order to explore the breeding mode of utilizing White Rex rabbit to produce superior Beaver hide rapid - ly,we performed the crossbreeding experiment between Beaver Rex rabbit line and White Rex rabbit line.The mating combination were as follows.Group 1: Beaver male × Beaver female;Group II: White male × White female;Group 3: Beaver male × White female.The growth performances and fur quality of the three groups were measured afterwards.The results showed that: The hybrid progeny had the highest growth speed and the lowest F/G;The hybrid progeny had the highest fur density and fur length,while its proportion of gun hair was between the White line and the Beaver line;This breeding mode (crossbred Beaver male and White female) is an optimum way of producing Beaver hide.
