| Abstract: | The newborn weigt,weaning weight,reproductive survival rate,six-month-weight and average day gain of the lambs in polled Doset×small tailed Han sheep×Tan sheep increase respectively by 20.92%,16.29%,13.00%,28.58%,and 36.29% compared with those in small tailed Han sheep×Tan sheep.The polycross method is a satisfactory technology for fattenning lambs quickly because the ternary hybrid lambs have good adaptability and high quality mutton. |
