Abstract
This experiment was designed to study the performance of Awassi pregnant ewes fed different types of roughage (green, hay and silage) during late pregnancy. Twenty four Awassi ewes (initial weight 47.01 ± 0.9 Kg) aged 2-3 years mated in mid June were used in a three treatments completely randomized design. Animals were housed and grouply penned 8 weeks before lambing. Treatment 1 (G1) consisted of alfalfa green roughage, Treatment 2 (G2) was fed whole crop maize silage and treatment 3 (G3) was fed dried alfalfa hay. All treated ewes were fed roughages ad libitum pluse 200 g/day concentrate. Types of roughage had no significant effect on ewes body weight changes (changes from the start of the experimental feeding to 24 hours post lambing).Ewes fed green roughage (G1) had heavier post-lambing weight than G2 and G3. lambs born from group 1 were heavier (P<0.01) than G2 and G3. Similar results were obtained for growth rate and weaning weight of lambs.
