【摘要】 本试验主要观察和统计了农大3号蛋鸡对产蛋箱的不同底面垫料(人工草垫、松木刨花、玻璃钢板),产蛋箱入口形式(挂帘子与不挂帘子),产蛋箱层高(0.15m、0.50m、0.85m)和产蛋箱类型(公共产蛋箱、单穴产蛋箱)的选择性情况,试验以不同情况下蛋鸡产蛋数量为依据,初步得出蛋鸡对不同产蛋箱的喜好程度。实验结果表明,在对底面垫料的选择上,蛋鸡在垫料为松木刨花的产蛋箱中平均产蛋2.86个,显著(P<0.01)高于人工草垫(0.44个)和玻璃钢板(0.67个),其中,后2种材料之间无显著性差异,破蛋率也均为零;在对产蛋箱入口挂帘与不挂帘的选择上,挂帘的产蛋箱中产蛋数(1.98个)要明显高于敞开的产蛋箱(0.67个),且差异显著;在对产蛋箱层高的选择上,蛋鸡对底面离地0.15m的产蛋箱选择性显著高于离地0.50m和0.85m的产蛋箱(P<0.01);另外,蛋鸡对产蛋箱类型的偏好选择结果为:公共产蛋箱(6.88个)>单穴产蛋箱(2.88个)。更多还原

【Abstract】 The preferring performances for layers on different nesting materials(artificial turf,sawdust, fiber reinforced plastics plate),different nesting seclusion(flap,no flap),different height(0.15m,0.50m, 0.85m)and different nest types(group laying nest,individual laying nest)were observed,based on the egg numbers in different types of nest boxes,conclusions were as follows,numbers of eggs(2.86)laid in sawdust nests were significantly higher(P<0.01)than the artificial turf(0.44)and FRP plate nests(0.67),no significant difference between the artificial turf and FRP plate,three materials nests had no broken eggs;Numbers of eggs laid in nests with flap(1.98)were significantly higher(P<0.01)than nests without flap(0.67);Numbers of eggs laid in 0.15m nests were significantly higher(P<0.01)than 0.50m and 0.85m nests;The results showed that group laying nest(6.88)performed better than individual laying nest(2.88).更多还原
