EFFECT OF PROTEIN AND ENERGY LEVELS ON SOME PERFORMANCE CHARACTERS OF AWASSI LAMBS

Abstract

Fourty eight Awassi lambs (5 months age ± 5 days) were used in this experiment. Lambs were allocated to six groups at randomly each of eight lambs. Effect of three levels of protein (12, 15 & 17%) and two levels of energy (standard 2450 Kcal and high 2750 Kcal) were studied on some performance characters of Awassi lambs (before and after slaughter) .All lambs were slaughtered after 90 days. The statistical analysis showed significant difference between the protein levels on average daily gain and rib eye area , while it showed no significant differences on the other characters studied in experiment. Mean while the energy levels showed no significant differences on all the studied characters.
