Ninety Naeini weather lambs (initial live weight 29.89 ± 2.9 kg) were used in a 92-day feeding experiment. Animals were blocked to each of nine dietary treatments. Diets contained either 2, 2.25 or 2.5 Mcal ME/Kg DM and 11.7, 13.2 or 14.7% CP diets were fed in a 3 × 3 factorial arrangement in randomized complete blocks. Lambs fed with high energy diets consumed significantly more feed (P %> http://jstnar.iut.ac.ir/article-1-232-en.pdf %P 149-160 %& 149 %! %9 Research %L A-10-2-232 %+ %G eng %@ 2476-3594 %[ 2001
