  • Impact of adding natural bioactive mixture composed of lemon, onion, and garlic juice at different levels on productive performance, egg quality, and some blood parameters of commercial laying hens

    • Authors: Omer, Hamed A. A.;  Advisor: -;  Participants: El-Mallah, Gamal M. H.; Abdel-Magid, Soha S.; Ahmed, Sawsan M.; El-Ghamry, Abdel Khalek A. (2019)

  • Adding LOG in laying hens’ diets significantly (P < 0.05) improved feed conversion throughout the second stage of egg collection in comparison with the control group. Inclusion of LOG in laying hen diets significantly (P < 0.05) improved the number of eggs/hen, percentage of egg production, and egg mass/hen throughout the second stage of egg collection comparing with the control (G1). Diet supplied by 1% LOG recorded the best value of yolk color (5.40) and yolk percentage (28.42%) compared with the other groups. Adding 2% or 3% LOG significantly (P < 0.05) decreased the total plasma cholesterol content compared to the control group. Inclusion of LOG at different levels significantly (...

  • Incorporation apricot seed kernel as untraditional source of protein in rabbit rations

    • Authors: Omer, Hamed A. A.;  Advisor: -;  Participants: Ahmed, Sawsan M.; Abedo, Abdelmegid A.; EL-Nomeary, Yasser A. A.; Nasr, Soad M.; Nassar, Somia A. (2020)

  • Inclusion ASK had no significant difference on red blood cell count (RBCs), white blood cell count (WBCs), packed cell volume percentages (PCV), hemoglobin concentration, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). However, levels of ASK (0.75, 1.5 and 3%) were significantly (P < 0.05) decreased eosinophils. Both basophiles and lymphocytes counts were significantly (P < 0.05) increased with ASK (R4). ASK had no significant effect on total protein, albumin, ALT, total cholesterol, triglycerides, urea, and creatinine. Meanwhile, rabbits received ration contained 4.5% ASK (R5) significantly (P < 0.05) increased t...

  • Mango (Mangifera indica) seed kernels as untraditional source of energy in Rahmani sheep rations

    • Authors: Omer, Hamed A. A.;  Advisor: -;  Participants: Tawila, Mohamed A.; Gad, Sawsan M.; Abdel-Magid, Soha S. (2019)

  • Nitrogen retention (NR) (NR % of nitrogen intake (NI) and NR % of digested nitrogen (DN)) values were significantly (P < 0.05) increased with increasing level of MSK in the sheep ration. Inclusion MSK significantly (P < 0.05) increased ruminal pH; however, it had no significant (P > 0.05) on both ammonia nitrogen (NH3-N) and total volatile fatty acid (TFVA) concentrations. Sampling time at 3 h post feeding significantly (P < 0.05) decreased ruminal pH in comparison with before and 6 h post feeding; meanwhile, sampling time had no significant effect (P > 0.05) on NH3-N concentration. Dietary treatment significantly (P < 0.05) increased the interaction between treatments and sampling ti...

  • Nutritional and chemical evaluation of dried pomegranate (Punica granatum L.) peels and studying the impact of level of inclusion in ration formulation on productive performance of growing Ossimi lambs

    • Authors: Omer, Hamed A. A.;  Advisor: -;  Participants: Abdel-Magid, Soha S.; Awadalla, Ibrahim M. (2019)

  • Total essential amino acid value was recorded at 51.30 g/100 g CP; meanwhile, value of non-essential amino acids was recorded at 48.37 g/100 g CP. The DPP contained 342, 120, 150, 68, and 56 mg/100 g of calcium (Ca), phosphorus (P), potassium (K), sodium (Na), and magnesium (Mg), respectively. Meanwhile, it contains 1.08, 0.86, 0.65, 6.11, and 1.07 mg/100 g of zinc (Zn), manganese (Mn), cobber (Cu), iron (Fe), and selenium (Se), respectively. Moreover, vitamins were determined by 0.141, 0.09, 13.26, 4.13, and 0.181 mg/100 g for vit. B1; vit. B2; vit. C; vit. E; and vit. A, respectively. Dried pomegranate peel contains high percentages of unsaturated fatty acids that evaluated by 76.96...
