  Objective: This study was designed to evaluate impact of adding M. oleifera and E. purpurea dried leaves to diets of Rhamani lactating ewes on their rumen fermentation characteristics, nutrients digestibility, blood parameters, milk yield, composition and its fatty acid profile. Materials and Methods: Fifteen Rhamani lactating ewes after 1 week of parturition were assigned randomly into three groups of 5 animals each using complete random design. The entire experimental period was 84 days. Ewes were fed dry matter according to 4% of their body weight. The first group was fed the basal diet which consisted of 30% CFM and 70% berseem (control diet). The second group was fed the control diet supplemented with Moringa oleifera (MO) dried leaves at 15 g kg–1 DM (T1), while the third group was fed the control diet supplemented with Echinacea purpurea (EP) dried leaves at 15 g kg–1 DM (T2). Results: The ewes fed MO supplemented diet (T1) showed significant increase in most of ruminal parameters (except ruminal pH) and nutrients digestibility coefficients followed by EP supplemented ewe’s diet (T2), while MO and EP supplementation decreased ruminal protozoal count significantly. There were no significant differences among all groups in blood albumin, globulin, ALT, AST and total lipids concentrations, but the ewes fed MO supplemented diets had higher (p<0.05) plasma protein and glucose values than those of control. The supplemented diets with MO and EP increased ewe’s milk productivity by 12.75 and 4.4%, respectively compared with the control diet. Milk component’s yield were higher (p<0.05) for MO supplemented ewes group than the other groups (control and T2). The EP treated ewes recorded the lowest (p<0.05) milk somatic cells count. The supplemented diets with MO and EP increased milk total unsaturated fatty acids by 14 and 11%, respectively compared with the control diet. Conclusion: The supplemented diets with MO and EP enhanced the performance of Rhamani lactating ewes with no harmful effects on their health.

  Background and Objective: Olive trees by products (OTB) as agro-waste not efficiently used and left it without treatment may cause serious economical, social and environmental problems. Biological treatments for such wastes can upgrade their nutritive values to be used as alternative feeds for ruminants. Investigate if their synergism between T. viride and S. cerevisiae and impact of each of them or their mixture on OTB digestibility and lactating Barki ewe's productivity are the main objectives of this study. Materials and Methods: Early lactating Barki ewes were randomly assigned into four groups of seven animals each using complete random design. Ewes were fed (4% of their body weight DM), 70% concentrate feed mixture (CFM)+30% untreated OTB (control group), 70% CFM+30% OTB treated with Trichoderma viride (R1), 70% CFM+30% OTB treated with Saccharomyces cerevisiae (R2) and 70% CFM+30% OTB treated with T. viride+S. cerevisiae (R3). Results: No synergism was noted between T. viride and S. cerevisiae on the tested parameters. Ruminal total volatile fatty acids and NH3-N concentrations, microbial protein synthesis and total protozoa count were higher in treated groups than control. Biological treatments increased (p<0.05) all nutrients digestibility, fiber fractions digestibility, milk production and milk components yields. Blood serum globulin, urea, ALT and AST concentrations were not change among all ewes groups, while biologically treated ewes had higher (p<0.05) serum total protein and albumin than those of control. Conclusion: Inclusion of biologically treated olive tree by products (OTB) in lactating ewe’s rations improved their productive performance with no deleterious effects on the treated animal’s health.
