| 摘 要： | 东北地区镇南种羊场饲育的细毛羊高弯腹毛面积的大小对毛长、体重、毛量三大经济性状的影响随生长发育阶级不同而不同,在育成期不显著(F=2.18~(ns),F=2.40~(ns),F=1.42~(ns)),在成年期则均非常显著(F=19.12~(**),F=6.98~(**),F=7.37~(**))。成年母羊高弯腹毛面积对毛长的影响是以10×10cm~2为临界面积,大于10×10cm~2面积羊毛长显著较短(P<0.01)。成年母羊高弯腹毛面积对体重的影响是高弯腹毛面积在10×10cm~2以上时,羊的体重显著较大(P<0.01)。成年母羊高弯腹毛面积对产毛量的影响:无高弯腹毛的羊,产毛量较高,有高弯腹毛,羊毛量减少,特别是5×5cm~2以上面积羊产毛量显著下降(P<0.01)。

| Abstract: | The influence of the area of High-crimped Abdominal Fibre(HCAF)of fine-wool sheep raised at Zhengnan Sheep Breeding Farm in Northeast China on the three important economic traits(wool length,body weight and wool quality)varied with the stages of growth and development.No influence was detected for the ewe lambs(F=2.18~(ns),F=2.40~(ns),F=1.42~(ns)),although they were significant for mature ewes(F=19.12~(**),F=6.98~(**),F=7.37~(**)).The influence of HCAF area of the adult ewe on staple length was crucial at the area of 10×10cm~2.The staple length of ewes with a HCAF area larger than 10×10cm~2 was significantly shorter(P<0.01).When the area of HCAF of the adult was above 10×10cm~2,body weight wasalso signifcantly heavier(P< 0.01).The influence of HCAF area of the adult ewe on wool production was as follows: Sheep without HCAF gave more wool,while those with HCAF was less (P<0.01).Wool production of sheep with HCAF area larger than 5×5 cm~2 decreased significantly(P<0.01). |
