	abstract = {Fifteen wether lambs (average BW 28.8 ± 1.8 kg) were used in a 128-d trial to examine effects of cyclical feeding changes on growth, feed efficiency and endocrine profiles. Control lambs were fed a 40\% concentrate diet (40C) at 1.5 × NE$_{\textrm{m}}$ requirement during period 1 (64 d). Another group (1\textit{x}/2\textit{x}) was fed 40C at 1 and 2 x NE$_{\textrm{m}}$ in 4-d intervals during period 1; a third group (70/10) 70\% and 10\% concentrate diets in 4-d intervals during period 1. To achieve dry matter intake comparable to controls, 70/10 lambs were fed at 1.79 (70C) and 1.21 (10C) × NE$_{\textrm{m}}$. All lambs were placed on the control diet during period 2 (32 d) and increased to 2 x maintenance during period 3 (32 d). During period 2, ADG and gain/feed of control lambs tended to be greater (\textit{P}{\textless}0.10) than for lambs fed alternating treatments. Liver weight as a percentage of hot carcass weight was greater (\textit{P}{\textless}0.05) for controls than for lambs fed alternating treatments. Hot carcass weight (\textit{P}=0.07) and dressing percentage (\textit{P}=0.09) tended to be greater for the 70/10 treatment than for controls. The 1\textit{x}/2\textit{x} treatment lowered (\textit{P}{\textless}0.05) serum cholesterol compared with other groups on d 65, but not on d 0 or 129. Smaller liver weight per unit of hot carcass weight for lambs in the 1\textit{x}/2\textit{x} and 70/10 treatments suggests a possible reduction of maintenance requirements.},
