文摘

Metabolizable protein (MP) requirements of Dorper × thin-tailed Han crossbred ram lambs are investigated. The daily MP requirement for maintenance is 3.69 g/kg BW0.75. The efficiency of MP utilization for maintenance is 0.42. The MP requirement for growth ranges from 19.4 to 77.4 g/d. The efficiency of MP utilization for growth is 0.75.
