In T1, T2 T3, remained mothers. No differences ( P >0.05) found food consumption or weight gains when treated groups compared controls. Lambs T3 performed same number episodes similar length, but less than groups. Cortisol concentrations all treatments. At end experiment, no difference that attempted 2, 3 4 (30%, 30% 20%, respectively).
