Effect Of Adrenergic Receptor Blockade With Yohimbin, Metroprolol Or Prazosin Onarrhythmogenic Dose Of Epinephrine In Xylazine-Kethamine Anesthetized Dogs, Ömer Bozdoğan, Abdullah Doğan

Turkish Journal of Veterinary & Animal Sciences

The arrhythmias occurring and caused to death during the anaesthesia is generated endogenous release of epinephrine or norepinephrine. Therefore, the effects of yohimbine (alpa-2 blocker), prazosin (alpha-1 blocker), metoprolol (beta-1 blocker) on the arrhythogenic dose of epinephrine in 10 dogs anesthetized with xylazine and kethamine combination, were researched in this study. The infusion of epinephrine, 1 mg/ml/min; yohimbine, 0.125 mg/kg; prazosin, 0.1 mg/kg; metoprolol 0.5 mg/kg in dose were made intravenously. The dose of epinephrine produced ventricular premature contraction and ventricular tachycardia were determined as total dose of epinephrine in mg/kg, given until the time that arrhythmia appeared. Metoprolol and …

Turkish Journal of Veterinary & Animal Sciences

Arginase (L-arginine amidino hydrolase E.C. 3.5.3.1) is an enzyme catalyzing the last stage of the Krebs-Henseleit cycle and, thus, converting arginine into urea and ornithine. Arginase also plays a part in protein and polyamine synthesis and is affected by hormones in terms of metabolic status. In the present study, erythrocyte, saliva, and serum arginase activity together with serum urea and estrogen levels were examined in Akkaraman and Ivesi sheep in pregnancy and postpartum. Comparisons were then made between the species. In pregnancy the urea level in saliva increased. However, the urea level in serum decreased. No clear difference was observed …

The Effects Of Egg Weight And Storage Time On Egg Weight Loss And Hatchability Traits Injapanese Quail, S. Kudret Saylam Jan 1999

The Effects Of Egg Weight And Storage Time On Egg Weight Loss And Hatchability Traits Injapanese Quail, S. Kudret Saylam

Turkish Journal of Veterinary & Animal Sciences

This study examined the effects of egg weight and storage time on egg weight loss and hatchability traits. Egg were stored for 1, 3, 5. 7. 9 and 11 days, and collected into 3 egg weight groups (light, medium and heavier). Storage room temperature was 18-20°C and relative humidity was 55-58%. Eggs were weighted individually at laying, before placing into hatching, on days 5, 10, 14 and 18 of the hatching period to determine egg weight loss. Fertility and hatchability values decreased with the storage time. Higher fertility and less hatching were observed in heavier egg weight group. There was …

The Effect Of Different Levels Of Nutrition At Last Period Of Gestation On Liveweight Of Ewes, Growth And Survival Rates Of Their Lambs, İsmai̇l Fi̇lya, Ali̇ Karabulut, Vedat Akgündüz

Turkish Journal of Veterinary & Animal Sciences

The animal material of the research was 3, 4 and 5 years old 210 Merino ewes and their lambs. The research was started at the beginning of the last 1.5 months period of gestation and continued until the lambs were reached 60 days age. It has been determined that 500 g and more (especially 1500 g) concentrate feed given fed ewes daily at the last 1.5 months period of gestation increased the liveweight and decreased the weight loss of ewes and increased birth weight, growth and survival rates of lambs.
