| Abstract: | The average weight of Liangshan semi-wool sheep ram and ewe lambs in 4-month is up to 26 kilograms.Lambs grow rapidly.The average daily gains (ADGs)in one-month and in suckling periods amount to 300 grams and 200 grams,respectively.With the increase of age,the growth rate slows down.The ADGs of ram and ewe lambs slow to 80.8 grams and 57.9 grams in 5-12 months,respectively.The average weight of ram and ewe in 18 month amounts to 60.4 kilograms and 46.1 kilograms,respectively.The average weight of ewe is 54.5 kilograms in 2.5 years |
