Effect of feeding date palm tree leaves as dried or silage incubated with or without bacteria on sheep performance during pregnancy and lactation periods, and lambs performance was investigated in the current study. Forty ewes (4 years old and 49.5±2.5 kg body weight) at the beginning of pregnancy were randomly assigned into four groups (n=10 in each). The first (C) fed control ration consisted of 60% concentrate feed mixture +40% berseem hay. The second (R1) fed ration contained 60% CFM + 40% dried date palm leaves (DDPL). The third (R2) fed ration contained 60% CFM + 40% silage DPL (SDPL). The fourth (R3) fed ration contained 60% CFM + 40% silage DPL incubated with Cellulomonas cellulasea (SBDPL). Digestibility trial was done at the end of lactation period. Results revealed that SBDPL increased (P≤0.05) body weight and total gain of ewes by progressing the pregnancy and lactation, with no significant difference with control group, followed by SDPL and DDPL, respectively. C and R3 improved (P≤0.05) digestibility coefficients and nutritive value compared with R2 and R1, in addition to a significant (P≤0.01) increase of rumen fermentations, protozoa and cellulolytic bacteria counts. Also, SBDPL increased (P≤0.05) serum glucose, total proteins, albumin, globulin, urea and creatinine concentrations, which affected milk yield and lambs performance comparing with SDPL and DDPL. Feeding date palm leaves silage with addition of bacteria is better than feeding silage without addition of bacteria or dried date palm leaves and could replace hay in rations of ewes during pregnancy and lactation.

lambs performance, economic conversion, feed efficiency, rumen fermentation characteristics, rumen ciliate protozoa and bacteria counts, blood parameters, nutrients digestibility, nutritive value, nitrogen and water balance as affected by feeding date palm leaves supplemented with cellulase, fibrolytic enzymes or combination of each other were investigated in the current study. Thirty weaning Barki lambs (3-4 months old and 12.50 kg live body weight) were randomly divided into five groups (6 lambs each ) to conduct growth trail followed by digestibility trail. Lambs received five treatments: T(1):Concentrate feed mixture (CFM) + berseem hay (BH) (control), T(2): CFM + untreated DPL + BH, T(3): CFM + DPL incubated with cellulase enzyme + BH, T(4): CFM + DPL incubated with Fibrolytic enzyme + BH, T(5): CFM + DPL incubated with cellulase and fibrolytic enzymes+ BH. Concentrate: roughage ratio was 50: 50%, DPL: BH ratio was 40: 10%. Enzymes supplementation improved lambs performance, whereas T5, T4 and T3 increased (P<0.05) feed intake, live body weight, total and daily gain, economic conversion and feed efficiency compared with T2. Also, lambs received T5, T4 and T3 showed better concentrations of rumen fermentation products, rumen microbes and blood serum parameters more than T2. All nutrients, digestibility, nutritive values and nitrogen balance significantly (P<0.05) improved as compared with T2. The results of treatments supplemented with enzymes were close to the results of control. Feeding date palm leaves treated with cellulase, fibrolytic enzymes or combination of each at ratio of 40 % from roughage had positive effect on lambs performance.

Forty Egyptian Saidi pregnant ewes were used to study the effect of iodine supplementation on physiological responses and the metabolic rate of Saidi pregnant ewes and their lambs' performance until weaning. Ewes were divided into two equal groups (20 ewes per each), control group and treatment group which was treated with 12 mg iodine solution every 2 days from the beginning of the last third of pregnancy and the lambing was during winter. Body weight of ewes at the end of pregnancy was higher in iodine supplemented group compared to control (43.9 vs. 41.1 kg, P<0.05). Gas volume per minute, tidal volume and metabolic rate values were significantly higher in the treated group compared to control group. Serum total protein and its fractions in addition to glucose concentrations tended to increase with iodine supplementation. Also, serum T3 and T4 concentrations were higher (P<0.05) in iodine supplemented group compared to control group (5.47 ng/dl &120.7 ug/dl vs. 4.0 ng/dl and 76.7 ug/dl, respectively). In conclusion, iodine supplementation beneficially influences the physiological responses, the metabolic rate and some blood constituents of Saidi pregnant ewes which subsequently improved the performance and the survivability of their lambs.

Effect of using two by-products (sugar beet pulp and date seeds) untreated or biologically treated with different combinations of fungi, bacteria and yeast in sheep feeding on digestibility coefficients, rumen fermentations and rumen microbes, and blood biochemicals was investigated. The study included laboratory experiment, digestibility trail and in vitro gas production. Digestibility trail included six experiments: T (1): Concentrate feed mixture (CFM) + berseem hay (BH) (Control). T (2): CFM contained untreated sugar beet pulp (SBP) and date seeds (DS) + BH. T (3): CFM contained SBP and DS treated with T. virideand S. cerevisiae + BH. T (4): CFM contained SBP and DS treated with T. viride and C. cellulasea + BH. T (5): CFM contained SBP and DS treated with C.cellulasea and S. cerevisiae+ BH. T (6): CFM contained SBP and DS treated with T. viride with C. cellulasea and S. cerevisiae+ BH. Biological combination treatments improved chemical analysis and fiber constituents, while reduced anti-nutritional factors of DS. T6, T4, T3 and T5 increased (P<0.05) digestibility coefficients, nutritive values, nitrogen utilization, microbial protein, rumen fermentations parameters and microbes numbers, gas production at different incubations times and blood serum total proteins and albumin were improved (P<0.05) in T6, T4, T3 and T5, respectively, compared with control and untreated groups. Control group showed higher values than untreated group. Inclusion of sugar beet pulp and date seeds untreated or treated with biological treatments to replace a part of 70% of common concentrate feed mixture had remarkable improved influence on sheep feeding.
