摘要
研究了不同生长阶段舍饲滩羊生长发育规律。结果表明,羔羊哺乳期体重增长速度较快,公羔在断奶之前生长速度与母羔相近;羔羊断奶期之后体重增长变缓;9月龄之后,公羊生长速度显著高于母羊;成年时公羊体重可达58 kg,母羊体重达42 kg。
The growth and development regularity of Tan Sheep under confinedness condition were studied. The results showed that the body weight of lamb increased rapidly in suckling period, and the growth of male lamb before weaning was similar with that of female lamb. After weaning, the growth of lamb reduced. The growth rate of rams was significantly higher than that of ewes after 9 months. The weights of adult rams were 58 kg and those of adult ewes were 42 kg.
