Male ICR (CD-1) mouse was used as an experimental model. The experiment duration was 23 weeks through which animals received diets containing ethephon in a series of concentrations of 0, 25, 50 and 75 milligram per kilogram diet respectively with and without 50 mg of gibberellic acid.  A significant variation was recorded between the effect of ethephon and that of ethephon - gibberellic acid combination on the activity of total mitochondrial ATPase in mice brain (P ≤ 0.05). Gibberellic acid antagonized the inhibition occurred by ethephon in case of the two smaller dietary concentrations 25 and 50 mg / kg diet. Ethephon induced a highly significant (p ≤ 0.01) concentration-dependent activation in Mg+2 ATPase in animals exposed to the two lower dietary concentrations 25 and 50 mg / kg with and without gibberellic acid. Ethephon induced a highly significant (p ≤ 0.01) dietary concentration-dependent inhibition in brain Na+/ K+ ATPase. Gibberellic acid obviously reduced inhibition in animals received the two smaller concentrations (25 and 50 mg / kg diet). No significant variation was found in brain acetyl cholinesterase neither among treated groups nor between these groups and the control (p ≥ 0.05). Gibberellic acid induced a highly significant recovery in the inhibited whole blood AChE in groups fed the low concentrations of 25 and 50 mg / kg diet (p ≤ 0.01). While at higher concentration (75 mg / kg diet) gibberellic acid showed an additive inhibitory effect on whole blood AChE.}, keywords = {Plant growth regulators,Ethephon,gibberellic acid,diet,Adenosine tri-phosphatase,Acetyl Cholinesterase,Mice}, url = {https://jappmu.journals.ekb.eg/article_86086.html}, eprint = {https://jappmu.journals.ekb.eg/article_86086_965103183759618a3751dacaba26df1f.pdf} } @article { author = {El-Gendy, M. and El-Komy, H. and Shehab El-Din, M. and Tolan, A. and Salem, M.}, title = {EFFECT OF SOME MEDICINAL PLANTS ON GROWTH PARAMETERS AND HEALTH STATUS OF NILE TILAPIA (Oreochromis niloticus).}, journal = {Journal of Animal and Poultry Production}, volume = {1}, number = {1}, pages = {11-22}, year = {2010}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2010.86088}, abstract = {This experiment was carried out to determine the effect of adding 0, 0.25, 0.50, 0.75, and 1% of dry thyme (Thymus vulgaris) and sage (Salvia officinalis) leaves to the ration of Nile tilapia (Oreochromis niloticus) on growth performance, feed and nutrient utilization, whole body composition, hematogram, protein profile and the activity of serum enzymes. Fingerlings of 15g average weight were stocked in 27 glass aquaria (105x32x40cm) at a rate of 15 fish in each. Fish in each aquarium were handly fed on the experimental pelleted feeds twice daily, six days a week at a rate of 3% of body weight daily for a period of 105 days. The results showed that, nutrient utilization, growth performance, hematogram, protein profile and activity of serum enzymes were improved with adding the thyme at level of 0.25 and 0.5% and sage at 0.5% and 0.75%. Also, fish fed rations containing 0.25,0.5, 0.75. and1% thyme or 0.75, and 1% sage had significantly (P<0.05) lower body fat, ash and energy contents but significantly (P<0.05) higher dry matter and body protein content.There were no significant mortalities among fish groups during the experimental period. Therefore, the levels of 0.25 or 0.5% thyme and 0.25, 0.5 or 0.75% sage are recommended as growth promoters for Nile tilapia due to their favorable effects on growth performance and health status.}, keywords = {Nile tilapia,Medicinal feed additives,Growth performance}, url = {https://jappmu.journals.ekb.eg/article_86088.html}, eprint = {https://jappmu.journals.ekb.eg/article_86088_caa82d95cba217498ea186bd73e00e12.pdf} } @article { author = {Abdel-Khalek, A. and Ganah, H. and Shehab El-Din, A.}, title = {EFFECT OF PMSG ADMINISTRATION IN RELATION TO FOLLICULAR DIAMETER ON SUPEROVULATORY RESPONSE AND EMBRYO QUALITY IN FRIESIAN COWS.}, journal = {Journal of Animal and Poultry Production}, volume = {1}, number = {1}, pages = {23-32}, year = {2010}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3642}, eissn = {2090-3723}, doi = {10.21608/jappmu.2010.86089}, abstract = {A total of 20 Friesian cows (450-550 Kg LBW, 3.5-5.5 years old and 1-3 parities) were used as donor cows. Cows were divided into 4 groups (5 animals in each) according to time of PMSG injection. Before treatment, cows in all groups were injected with 2 ml PGF2α (Estrumate) to start oestrous cycles. Cows in the 1st group (Control, n=5) were i.m. injected with a single dose of 2500 IU PMSG on day 10 of the oestrous cycle. However, in the 2nd, 3rd and 4th groups, cows were injected i.m. with a single dose of 2500 IU PMSG when diameter of the dominant follicle reach 5-7.5 mm (G2, n=5), >7.5-10 mm (G3, n=5) and >10 mm (G4, n=5). After 48 h of PMSG injection in each group, cows in all groups were injected with 2 ml Estrumate and artificially inseminated (AI) when excepted estrous. Flushing was conducted 7 days after AI to determine the ovulatory response. Ultrasonography device was used during treatment period to record the number of follicles and CL and diameter of the follicles for PMSG injection.Results showed that day of PMSG treatment averaged 7.2, 9.6 and 8.2 for cows in G2, G3 and G4, respectively. All cows in G1 and G3 (100%) produced CL vs. 60 and 80% of cows in G2 and G4, respectively. Response rate of embryo production was only detected in G1 and G3, being 60 and 80%, respectively.No embryos were recovered from cows in G2 and G4.Average number of CLs/cow was higher (P<0.05) in G1 and G3 (8.0 and 7.4) than in G2 and G4 (1.0 and 3.0), respectively. Cows in G1 and G3 showed the highest (P<0.05) total response (CLs and UOF), being 9.4 and 9.8/cow, respectively. Averages number of total and transferable embryos were higher (P<0.05) in G3 by about 42 and 44% than in G1. Recovery rate of total and transferable embryos were higher in G3 than in G1 (73.0 and 70.0% vs. 47.5 and 45.0%, respectively). Yield of embryos at morula and blastocyst stageswas higher in G3 than in G1. Cows in G3 showed the highest distribution of embryos at morula stage (37.0%) versus the highest distribution of compact morula in G1 (42.1%). Cows in G3 increased yield of excellent embryos/cow (2.2 vs. 1.0) and good embryos/cow (3.0 vs. 1.8) as compared to those in G1. Excellent and good embryos represented 40.7 and 55.6% in G3, being higher than 26.3 and 47.4% in G1. The differences in production of embryos at different stages or grades were not significant. In conclusion, the obtained results, indicated that the potentiality of PMSG injection to induce high superovulatory response in cattle is highly related to follicular diameter . Under the experimental conditions of present study, appropriate time for SO in Friesian cows treated with 2500 IU of PMSG was when diameter of the dominant follicle reached a rang from ≤7.5-10 mm to reflect the highest ovulatory response and the best number of transferable embryos of excellent grade.}, keywords = {cows,follicular diameter,PMSG,SO,embryo}, url = {https://jappmu.journals.ekb.eg/article_86089.html}, eprint = {https://jappmu.journals.ekb.eg/article_86089_a17e64b1247ae7af96e8727523c824b3.pdf} }
