Anwar; N. Ullah; A. Mehmood; M.A. Mirza Abstract: The study was conducted to compare the superovularoty response of buffalo in winter and summer. Four adult buffaloes were treated with follicle stimulating hormone (FSH) during winter (November to January) and three buffaloes in summer (June and July). Superovulatoty response was determined by estimating the number of corpora lutea (CL) palpated per rectum on day 6 of the oestrus cycle (oestrus = day 0). The number and quality of embryos collected were also studied. A better ovarian response was observed in winter (5.8±0.3 CL) than in summer (2.7±1.2CL) (P<0.05). A mean (±SE) 1.3±0.9 embryos were recovered during winter compared to 0.5±0.4 embryos in summer. All the embryos recovered in winter were of good quality whereas only fair quality embryos were recovered in summer. Two pregnancies were achieved in winter after transfer of three embryos to three synchronized recipient buffaloes. The study showed a better ovarian response of buffalo to FSH in winter. 2000-01-05T00:00:00Z http://localhost:80/xmlui/handle/123456789/18120 Title: DISPOSITION KINETICS AND DOSAGE REGIMEN OF INTRAVENOUSLY INJECTED KANAMYCIN IN BUFFALOES Authors: T. Saeed; R. Ahrnad; M. Nawaz; T. Iqbal Abstract: Genetical variations in the local population apprise of the need for describing biodisposition and fate of drug in indigenous species and environments. Kanamycin is one of the extensively used antibiotics in veterinary clinics. Its disposition kinetics was investigated in local female buffaloes following intravenous dose of 5 mg/Kg body weight. The blood samples collected at different time intervals were analyzed for kanamycin concentration by a microbiological assay. Two compartment model kinetics analysis of plasma kanamycin concentration versus time data revealed its rapid distribution and elimination with half life (t 5.42±0.39 hours (Mean ± SE). Total body clearance of Kanamycin in buffaloes were 2.59+0.17 mlimin./Kg body weight. To maintain the minimum inhibitory concentration (MIC) of 2 pg/mI of plasma, optimal dosage regimen of 11.8 mg/kg body weight for primary and 9.4 mg/kg body weight for maintenance to be repeated after 12 hours interval has been suggested in buffaloes. 2000-01-04T00:00:00Z http://localhost:80/xmlui/handle/123456789/18118 Title: PRELIMINARY OBSERVATIONS ON ESCHERICHIA COLT INFECTION IN NEONATAL CALVES IN EASTERN PROVINCE OF SAUDI AROMA Authors: Baldish Alhendi; Abduslam Abdullah Abstract: Five neonatal calves with diarrhoea were presented to the Veterinary Teaching Hospital for treatment. Main clinical signs and results of faecal examination were reported. E. cola was isolated from all calves. Mixed isolates of E. coli and Proteus spp. were found in 3 calves. No mortality was observed among examined calves. The E. col' isolated was subjected to antiobiotic sensitivity test against six antibiotics. Various aspects concerning diarrhoea in neonatal calves are discussed. 2000-01-03T00:00:00Z http://localhost:80/xmlui/handle/123456789/18098 Title: OBSERVATIONS ON CLINICAL TREATMENT TRIALS OF INDUCED ESCHERICHIA COLS' DIARRHOEA IN BUFFALO NEONATAL CALVES Authors: M. T. Jawed; A. Khan; Abid Hussain; Babar Niaz Abstract: The study was conducted on 24 calves of one-week-age, randomly divided into four groups, of six calves each. First three groups were experimentally infected with E. cob and given treatment in various combinations, while group four was taken as uninfected untreated control. Results obtained on different parameters were, green to yellow-white diarrhoea with variable consistency from watery to semisolid. Generally in all groups during first two days, calves passed faeces around 6-10 times a day and this frequency lowered in about 2-4 days. During first 3-4 days of treatment, all calves appeared weak, dull. depressed with cold skin and wetness of the muzzle, while oral mucosa was pale and eyes were sunken. Overall mean respiration rate of treatment groups was slower (P<0.05) than control group. However, pulse rate showed no difference between treatment and control group. Overall mean rectal temperature was lower (P<0.05) in calves treated with antibiotic alone and with antibiotic + electrolytes, while body weight was higher (P<0.05) in calves treated with antibiotic but was lower along with creatinine (P<0.05) in calves treated with antibiotic + electrolytes and those treated with electrolytes alone. 2000-01-03T00:00:00Z
