Abstract: The objective of this study was to investigate the effect of vitamin E and Se injection of nursing Awassi ewes on the performance of ewes (body weight change, milk yield, and composition) and their lambs (growth rate and weaning weight). Twenty-eight Awassi ewes were randomly assigned upon lambing to one of two groups; Control (n=13) and Inject (n=15), where ewes received 0 (control) or 15 plus 0.05 mg kg−1 BW of vitamin E and Se, respectively (inject). Intramuscular injections were given at 1 and 4 wk postpartum. Body weight (BW) of ewes and their lambs were recorded at lambing and at 2, 4, 6, and 8 wk postpartum. Milk yield and composition were measured at 2, 4, and 6 wk postpartum and somatic cell count (SCC) was evaluated weekly (from lambing through 8 wk). Injecting nursing ewes with vitamin E and Se had no effects (P≥0.10) on BW change of ewes, milk yield and composition, composition yields, or milk SCC. Injecting nursing ewes with vitamin E and Se had no significant effects (P≥0.29) on weaning weight, BW gain, or growth rate of their lambs. Under conditions similar to the current study, injecting nursing Awassi ewes with vitamin E and Se at 1 and 4 wk postpartum was not effective in improving the performance of ewes and their suckling lambs. Such observations could be attributed to the time of supplementation (pre- or post-partum) and/or the adequate basal vitamin E status in ewes. = L’objectif de cette e´tude e´ tait d’e´valuer les effets d’injections de vitamine E et de se´ le´nium (Se) dans des brebis Awassi qui allaitent sur la performance de ces brebis (changement de poids corporel, production de lait et composition du lait) et de leurs agneaux (taux de croissance et poids au sevrage). Vingt-huit brebis Awassi ont e´ te´ assigne´es ale´atoirement a` l’un de deux groupes apre` s l’agnelage ; te´moin (n 13) et Inject (n 15), ou` les brebis ont rec¸u 0 (te´moin) ou 15 plus 0,05 mg/kg de poids corporel de vitamine E et de Se, respectivement (Inject). Les injections intramusculaires ont e´ te´ effectue´es 1 et 4 semaines post-partum. Les poids corporels (BW « body weight ») des brebis et des agneaux ont e´te´ enregistre´s a` l’agnelage ainsi qu’a` 2, 4, 6, et 8 semaines post-partum. La production de lait et sa composition ont e´ te´ mesure´es a` 2, 4, et 6 semaines post-partum et la nume´ration des cellules somatiques (SCC « somatic cell countt ») a e´te´ e´value´ de fac¸on hebdomadaire de l’agnelage jusqu’a` 8 semaines post-partum. Injecter la vitamine E et le Se dans les brebis qui allaitent n’a pas eu d’effet (P]0,10) sur le changement de BW des brebis, la production ou la composition du lait, les rendements de composition ou les SCC du lait. L’injection de vitamine E et de Se dans les brebis qui allaitent n’a pas eu d’effet significatif (P]0,29) sur le poids au sevrage, le gain de BW ou le taux de croissance de leurs agneaux. Sous des conditions similaires a` celles de la pre´sente e´tude, l’injection de vitamine E et de Se aux brebis Awassi qui allaitent aux semaines 1 et 4 post-partum n’e´ tait pas efficace pour ame´ liorer la performance des brebis ni de leurs agneaux de lait. Ces observations peuvent eˆ tre attribue´es au temps de supple´mentation (pre- ou post-partum) et/ou le niveau basal ade´quat en vitamine E chez les brebis.
