Compare Study on Wool Growth of F_1 Crossbreeding from Simon×Poll Dorset Sheep×Han Sheep and F_1 from Poll Dorset×Han Sheep as well as F_1 from Texel×Han Sheep

150 sheep from different breed were divided randomly into 3 groups which consist of 50 sheep in each group.F1 from Simon×Dorset Sheep×Han Sheep and F1 from Dorset×Han sheep as well as Texel×Han Sheep were chosen for feeding experiment from birth to 6-month old.Wool growth speed and exterior quality were observed,wool yield and length were measured for 6-month old,meanwhile,adaptability,disease resistance of hybrid combination were observed in full house situation,feeding efficiency was analyzed.The results showed that wool performance of F1 from Simon×Dorset×Han sheep was better than F1 from Dorset×Han sheep and F1 from Texel×Han sheep.
