Five chalcones have been synthesized via Clasien- Schmidt condensation under alkaline conditions. Structures of the synthesized chalcones confirmed by their melting point (mp), Infrared spectrum IR and Proton Nuclear Magnetic Resonance (1H-NMR) spectra. Total antioxidant capacity (TAC) of the synthesized compounds were measured according to Phosphomolybdenum method, and the results indicated that chalcone V [1-(benzofuran-2-yl)-3-(4-methoxyphenyl)-prop-2-en-1-one] has the highest antioxidant activity among the five synthesized chalcones.Sixteen dairy Zaraibi goats have been divided into three groups according to their parity, milk yield, body weight and age. G1 (4 animals) served as control group and were fed the basal diet, G2 (6 animals) were fed the basal diet + 250 mg/head/day of chalcone V and G3(6 animals) were fed the basal diet + 500 mg/head/day of chalcone V for a period of 90 days. Results showed insignificant increase in milk yield of the three groups (1.07, 1.07 and 1.14 L, respectively), in milk protein (2.80, 2.87 and 2.92%, respectively) and milk somatic cells (SCC) (956.4*103, 981.1*103and 1181.7*103 cells/ml, respectively).While there were insignificant decrease in milk fat of the three groups (3.70, 3.45 and 3.31%, respectively), milk lactose (4.45, 4.45 and 4.36%, respectively) and total milk solids (11.67, 11.47 and 11.29%, respectively). Total antioxidant capacity of blood serum was insignificantly higher in G2 than G1 and G3 (2.86, 3.25, 2.83 mM/L, respectively).

Twenty-four healthy Sohagi male lambs of (7-8 month old and 24.47±0.15 kg body weight) randomly assigned into four groups (6 animals each).The experiment extended for 25-weeks after two weeks for adaptation. Basal diet was formulated to meet the nutritional requirements according to NRC (1985) except Se. Lambs in the first group fed basal diet as a control whereas lambs in groups T2, T3, and T4 were fed the basal diet supplemented with 0.1 mg/kg DM sodium selenite, vitamin E and selenium and selenized yeast, respectively. Three rams of each group (averaged 44.21 ± 4.90 kg body weight) by end of feeding trial were placed in metabolic cages to evaluate the digestibility and feeding values of the experimental rations. Five-days preliminary period followed by ten days collection period with quantitative collection the faeces. Blood samples from three animals in each group were collected before offering feed and water throughout the experimental period at 0, 1, 2, 3, 4 and 5 months of the experimental period .Results showed that ration supplemented with selenized yeast (T4) had higher DM, OM, CP, EE and NFE digestibility coefficients than the other three treatments and the differences almost were significant in most nutrients between T4 and each of T2 and control. Generally, digestibility coefficients of DM were 66.66%, 68.94%, 70.31%, and 71.98% for control, T2, T3 and T4, respectively. Also, the values of TDN and DCP behaved similar to digestion coefficients of all nutrients . The present results illustrated that testes weight recorded higher value in T4 ,T3 , T2 compared to control, but the differences among treatments were not significant . In addition, the concentrations of selenium in testes were significantly (P<0.01) higher in T4, followed by T3 and T2, while the lowest value was recorded in the control group, with significant difference between each other. Also, results illustrated that values of testes circumference, testes volume and testosterone concentration at the beginning of experiment showed non significant differences among treatments, while at 1, 2, 3, 4 and 5 months of experimental period, T4 group recorded higher (p<0.01) to 0.05) values for the three mentioned testes parameters of T3, T2 and control treatments. Generally, T4 and T3 recorded higher significant values in comparison with T2 and control . Also, data showed that both diameter of testes and testosterone concentration increased with advancing of age. In addition, values of thyroid hormones concentrations recorded significantly (p<0.01) higher values as a results of supplementation of different sources of selenium compared to control group. Moreover, concentration of both hormones in T4 (selenized yeast) and T3 (vitamin E and selenium) showed significantly higher activity of both thyroid hormones in comparison with T2 (sodium selenite) and control groups. Also, both hormones concentrations increased with advancing age.It can be concluded that supplementation of selenium in the ration of sheep especially in the form of selenized yeast led to an improvement in nutritive value of rations and reproductive performance through the favorable effects on weight, testes diameters and testosterone concentration as well as the thyroid hormones concentrations in blood of male lambs.}, keywords = {}, url = {https://ejsgs.journals.ekb.eg/article_26336.html}, eprint = {https://ejsgs.journals.ekb.eg/article_26336_3e2983698c103c09d531aadec7051ccd.pdf} } @article { author = {I., Abd-EI Moty and El-barody, M. and Zanouny, A. and Sallam, M. and Abd EI Hakeam, A.}, title = {Effect of Nigella Sativa seeds, Royal jelly and Pregnant Mare Serum Gonadotrophine on Some Reproductive Traits of Ossimi Ewes}, journal = {Egyptian Journal of Sheep and Goats Sciences}, volume = {11}, number = {3}, pages = {1-8}, year = {2016}, publisher = {Egyptian Association for Sheep and Goats}, issn = {2090-0386}, eissn = {2090-0376}, doi = {10.21608/ejsgs.2016.26337}, abstract = {ABSTARCTForty-eight Ossimi ewes aged 2-4 years and averaged 41±2.5 kg body weights were randomlyassigned into four equal groups (12/ each).

Control group not drenched anything. First group (T1) daily drenched orally100 mg Nigella Sativa seeds (NSS) powder/kg/head for 12 days starting at the time of sponge insertionuntil the time of sponge withdrawal. The second group (T2) drenched orally fresh Royal jelly (RJ) 500mg per day/for 12 days, starting at time of sponge insertion until sponge withdrawal.

The third group (T3) was intramuscularly injected at time of spongewithdrawal, with 750 IU of Pregnant Mare Serum gonadotropin (PMSG).A fertile, Ossimi ram ran with the ewes immediately following sponge removal at (day 0). Ewesobserved three times daily to identify and detect estrus for 3 days. Ultrasound scanner apparatus wasused to count number of corpus luteum and diagnose of pregnancy. Detection of pregnancy dependedon presence of embryos and/or embryonic fluid that filled the uterus.The results indicated that the response of ewes to estrus synchronization did not differ amongthe four groups. The response of the four groups was 100%.

Moreover, G5 (GPG) and G3 (CIDR) groups showed significant higher percentof non- return to estrus (85.71 and 83.33%, respectively) than that observed in ram effect (G2) andcontrol (G1) groups (70 and 66.67%, respectively). The time to conception was significantly shorterin G3, G4 and G5 than the control group (G1).The number of large follicles of total ovaries was significantly low in ram effect group (G2)compared to those in G3, G4 and G5, being the highest in G5. Moreover, hormonal treated ewes ingroups G3, G4 and G5 showed significantly higher total CLs numbers (1.00±0.32, 1.40±0.24 and1.67±0.21/ ewe, respectively) than in ram effect and control groups (G2 and G1) (0.75±0.25 and0.60±0.24/ewe, respectively), where it was the highest in G5 (GPG group).Progesterone levels, recorded before treatments, were significantly lower in hormonal treatedgroups G3, G4 and G5 (0.87±0.20, 0.77±0.70 and 0.80±0.59 ng/mL, respectively) than in G1 andG2 (9.19±0.15and 3.86±1.07 ng/mL, respectively). Their levels decreased in all experimental groupsreaching minimal values at the onset of estrus (< 0.5 ng/ml). On day 30 post mating, G4 and G5showed significantly the highest progesterone concentration comparing to other groups.The pregnancy rate and number of lamb born/ ewe lambed were significantly the highest in G5(80 and 127%, respectively) while the lowest in G1 (46.67 and 53.33%, respectively). In addition,percentage of ewes lambed twins was higher in ewes treated with GPG protocol (G5, 58.33%)followed by those treated with 500 IU PMSG after MAP (G4) and CIDR (G3) withdrawal (50 and40 %, respectively).In conclusion, GnRH– PGF2α– GnRH (GPG) protocol found to be more effective for estrussynchronization than CIDR and MAP+ PMSG. Treatment of Rhamani ewes during summer seasonwith GPG protocol increased estrus and ovarian activities, as well as, pregnancy, lambing andmultiple birth rates.}, keywords = {}, url = {https://ejsgs.journals.ekb.eg/article_26339.html}, eprint = {https://ejsgs.journals.ekb.eg/article_26339_072ad982312c7d8c1865262e44ceb486.pdf} } @article { author = {H, Daghash. and Fahmy, S. and Hassan, T. and Ali, M.}, title = {Impacts of GnRH, PMSG and hCG treatments on follicular diameter, conception and lambing rates of Egyptian ewe lambs using intravaginal sponges}, journal = {Egyptian Journal of Sheep and Goats Sciences}, volume = {11}, number = {3}, pages = {1-1}, year = {2016}, publisher = {Egyptian Association for Sheep and Goats}, issn = {2090-0386}, eissn = {2090-0376}, doi = {10.21608/ejsgs.2016.26340}, abstract = {The influence of gonadotropin releasing hormone (GnRH), Pregnant Mare SerumGonadotropin (PMSG) and human Chronic Gonadotropin (hCG) on some reproductive responses ofEgyptian ewe lambs was evaluated.

Twenty-five lactating goats 2-3 years old and 26.84 kg weight were assigned randomly to five groups(five in each)using a randomized complete block design. Animals fed Berseem hay (BH) plus concentrate feed mixture (CFM). Five levels (0, 25, 50, 75 and 100%) of EMTAP used to replace berseem hay during the experiment. The experimental period extended one week postpartum until the fourth month of lactation .Group R1fed ration contained 100% BH plus CFM and served as control, while groupsR2, R3, R4 and R5 fed four levels of EMTAP (25, 50, 75 and 100%), respectively by replacing BH in the ration. Results showed that goats fed R3 diet (50% BH + 50% EMTAP) had significantly (P<0.05) better nutrients digestibility and feeding values compared with control. Significant (P<0.05) increases observed in milk production up to 13.06% and in milk fat yield up to 43.70% for R3 compared with control. Also, R3 recorded the best value of feed conversion and the best relative economic efficiency compared with other experimental groups. Daily gain of kids from birth up to weaning was significantly (P<0.05) higher with R3 than kids fed the other experimental rations.It conclude that the nutritional value of tomato pomace and apple pomace were markedly improved when mixed together (at ratio 50:50), for making silage. The study conclude that replacement of berseem hay with EMTAP up to 50% in the diets of dairy goats could improve milk yield and composition without any adverse effect on their performance.}, keywords = {}, url = {https://ejsgs.journals.ekb.eg/article_26420.html}, eprint = {https://ejsgs.journals.ekb.eg/article_26420_0ed07631c8767be16f3269af22b5c36d.pdf} }
