Twenty-four male Barki lambs divided into three groups were used. All animals fed 2% of animal body weight on concentrate feed mixture, while the roughages fed ad libitum, thus the difference among groups was in roughage material. The control group fed Berssem hay, second group fed Moringa stalks treated with fungus (Trichoderma reesei) and third group fed Moringa stalks treated with yeast (Saccharomyces cervisiae). All skins and leathers were evaluated chemically and physically, in addition wool characteristics were determined for wool samples. The results indicated that majority of physical and chemical properties of skins, leathers and wool were not significantly differed among groups. Therefore, using Moringa stalks as roughage in rations not affected the quality of wool, skins or leathers, which are considered acceptable in different industrial purposes such as carpets, upper shoe, garment and lining.}, keywords = {}, url = {https://ejsgs.journals.ekb.eg/article_26304.html}, eprint = {https://ejsgs.journals.ekb.eg/article_26304_48ebd3a4508e99568b574e40a6183404.pdf} } @article { author = {Mohamed, M. and Zanouny, A.}, title = {EFFECT OF PROPOLIS AS AN EXTENDR SUPPLEMENTATION ON RAM SEMEN QUALITY AND SPERM PENTRATION ABILITY}, journal = {Egyptian Journal of Sheep and Goats Sciences}, volume = {12}, number = {3}, pages = {1-12}, year = {2017}, publisher = {Egyptian Association for Sheep and Goats}, issn = {2090-0386}, eissn = {2090-0376}, doi = {10.21608/ejsgs.2017.26305}, abstract = {ABSTARCTPropolis as natural antibiotic has lot of flavonoids, organic compounds, fatty acids steroids, amino acids and others.

This study was designed to determine the effects of various concentrations of propolis powder extract or glue compared with synthetic antibiotic on motility (%), live spermatozoa (%), normality (%) and acrosomal intact (%) traits of ram spermatozoa (as indicator for semen quality), enzymatic activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and lactic dehydrogenase (LDH); penetration ability and resistance to bacterial contamination in ram semen extender. Ethanolic extract of propolis was prepared by dissolving either powder or glue (10 grams/100 ml ethanol, w/v) incubated at 37 °C for 6 hrs. Seven semen extenders included M1 (control), M2: 400μl pen-sterp and M3: 600μl pen-sterp as synthetic antibiotic; M4: 400μl and M5: 600μl propolis powder; M6: 400μl and M7: 600μl propolis glue as natural antibiotic, respectively. The results showed that semen quality traits decreased significantly (P<0.01) with incubation time in all extenders. On the other hand, all sperm parameters and penetration ability were improved (P<0.01) while enzymatic activities (ALT, AST, ALP and LDH) were significantly (P<0.01) decreased in extenders treated groups [(synthetic and natural antibiotic, either propolis powder or glue)] compared with control group. Furthermore, a higher antimicrobial activity (P<0.01) for M5 and M7 extenders were observed compared with other semen extenders.

Eighteen Zaribi goats (averaged 43 kg ± 1Kg body weight) were divided into three similar groups (6 goats each) for use in the feeding trial, which lasted 90 days. A randomized complete block designs was applied. Experimental rations comprised iso-nitrogenous and iso caloric based on concentrate feed mixture (CFM) and berseem hay in three roughage to concentrate ratios as follow: 50:50(T1), 55:45(T2) and60:40(T3). The three rations were supplemented with 30 g SFO /kg of DM intakeThe results showed that dry matter intake (P < 0.05) decreased with increasing the ratio of roughage by 26.9% and 41.0 % for T2 and T3 compared with T1, respectively. There were no significant differences among groups in DM digestibility, while OM and EE digestibility (P < 0.05) were higher in T1 ration (high concentrate) than both T2 and T3 rations (lower concentrate). All nutrients digestibility significantly (P < 0.05) increased with T1 (high concentrate and low roughage) than T3 (low concentrate and high roughage), while, no significant difference between T1 and T2 rations. On the other hand, TDN values did not affected by concentrate to roughage ratios. While, DCP decreased in T2 and T3 by increasing roughage ratio. High-roughage diet (T2 and T3) resulted in a lower rumen pH and higher total rumen VFA concentration, whereas, high concentrate diet increased rumen pH and decreased rumen VFA concentration. High-concentrate diet increased rumen ammonia-N (P < 0.05) and molar proportion of acetate to propionate. There were no significant differences in milk yield, as 4% fat corrected milk, among animals fed the tested rations supplemented with sunflower oil (SFO) as source of unsaturated fatty acids. The high roughage diets (T2 and T3) resulted in increase in linoleic (c18:2) and linolenic acid (c18:3) concentration by 69 and 45%, respectively compared with control (T1). Also, kids of T1 group had significant (P < 0.05) higher birth weight than other groups, while, there were no significant difference in daily gain among kids of the three groups.In conclusion, high concentrate diet could have better milk yield and protein percentage, while have less fat % and yield, compare to high roughage diet. Suckling kids could benefit more gain with dams fed high concentrate diet. Low roughage diet also develop better fat profile in milk.

Animal allotted randomly into three similar groups (5 animals each) to receive one of the experimental diets. The control ration (CR) consisted of concentrate feed mixture (CFM), Berseem hegazi hay (BHH) and rice straw (RS). The two tested groups fed the same control ration supplemented either with 10 mg large size particles of zinc (LP-Zn) or 5 mg nano particles of zinc (NP-Zn) per kg CFM, G2 and G3 respectively.Results indicated that digestibility of most nutrients (DM, OM, CF and NFE) were significantly the highest with NP-Zn ration in comparison with other treatments. Similar trends observed with TDN and DCP values among treatments. Percentage of body weight changes during experimental period increased (P<0.05) by 4.96 and 12.54 % for ewes treated by LP-Zn and NP-Zn, respectively. In addition, the feed intake calculated as DMI, TDN and DCP were significantly higher with NP-Zn ration than other ones. Actual daily milk yield (ADMY) and 6% fat corrected milk yield (FCMY) were higher for both tested rations (LP-Zn & NP-Zn) than control, with superiority of NP-Zn ration. Data indicated that supplementation of diet with NP-Zn affected positively (P<0.01) the total antioxidant capacity (TAC), glutathione-S-transferase (GST) activity, prolactin, triiodothyronine (T3), and thyroxin (T4) concentrations at 15, 45 and 75 days post-lambing in comparison to control group for ewes and their lambs. Also, concentration of immunoglobulin (IgG) in serum samples of ewes and their lambs recorded the highest values with NP-Zn group. Serum total protein, albumin, globulin and glucose values in NP-Zn group recorded the highest values, followed by LP-Zn group, while control group had the lowest, either for ewes or suckling lambs.
