AB - Effects of the β-adrenergic agonist metaproterenol were studied daily gain, carcass composition and feed consumption of Varamini female lambs were studied. Thirty lambs were randomly assigned to a randomized complete block design with three groups (treatments) and two blocks (live weight). The ration was similar for all groups (ME: 2.6 MCal/kg, CP: 14.9%) and lambs were fed ad libitum. Metaproterenol was injected subcutaneously at 0 (control), 7 (low dose) and 14 (high dose) µg kg-1 w75. Lambs were weighed at 20-day intervals. Mean daily weight gain and feed conversion ratio improved significantly by metaproterenol (P LA eng UL http://jcpp.iut.ac.ir/article-1-73-en.html M3 ER -
