Abstract | A study using 15 wether lambs (avg wt of 28.8 kg) was conducted (eight 16-d periods, five lambs/treatment) to examine effects of cyclic intake of dry matter or energy density. During the first four periods, controls received a 40% concentrate diet (40C) at 1.5 x NE., another group (1X/2X) received 40C at 1 and 2 x NE, in 4-d intervals and a third group (70/10) received 70 and 10% concentrate diets in 4-d intervals. All lambs were fed the control diet during periods 5 and 6 and increased to 2 x maintenance during periods 7-8. Blood samples were collected on d 0, 65 and 129. During periods 5-6, average daily gain and gain:feed ratio of the control group were greater (P |
