Vet. Med. Sci.) is a biannual journal that publishes peer-reviewed papers on the fields of veterinary and biomedical sciences. Contributions may be in the form of original research or review articles and case reports. The goal of this journal is to provide a platform for scientists to promote, share and discuss various new issues and developments in all aspects of veterinary and biomedical sciences.</p> </div> </div> </div> </div> en-US Libyan Journal of Veterinary and Medical Sciences 2410-9215 https://uot.edu.ly/journals/index.php/ljvms/article/view/1609 <p>In this study, 342 imported male lambs were investigated for pasteurellosis. The lambs’ ages ranged from 5 to 7 months. Before exportation, lambs were reared on dry pastures and there were no vaccination records for the animals. Lambs were classified into 4 groups (A, B, C and D) according to the management and medications received. The number of animals allocated in the four groups was 150, 13, 79 and100 respectively. Group A received multivitamins intramuscularly after transportation, and was treated with 3% oxytetracycline (90mg/10kg body weight (BW)) intramuscularly for seven days from outbreak occurrence. Group B was treated with 33% sulphadimidine (1130mg/10kg BW) intramuscularly for three days as a first treatment, followed by 20% tylosin (200g/10kg BW) intramuscularly for two days. Group C was treated randomly with one dose of 3% oxytetracycline (90mg/10kg BW) intramuscularly, one dose of 33% sulphadimidine (1130mg/10kg BW) intramuscularly and one dose of tylosin (200mg/10kg BW) intramuscularly followed by two injections of 20% oxytetracycline (200mg/10kg BW intramuscularly). Group D was treated with three doses of oxytetracycline (200mg/10kg BW intramuscularly) for 5 days. Diarrhea was observed in all groups. In addition, bloody diarrhea was also noted in group A. The 3% oxytetracycline was administered orally to the diarrheic animals and the highest mortality rate was seen in the group which did not receive any dose of oxytetracycline. The group of animals which shown bloody diarrhea and was treated orally with 3% oxytetracycline and with oxytetracycline intramuscularly showed health improvement. Good management including good shelter and nutritional supplements containing multivitamins and minerals are beneficial for feedlot lambs. Systemic administration of 2 to 3 prophylactic doses of oxytetracycline (90mg/10kg BW) within 7 to 10 days after transportation along with oral administration of 3% oxytetracycline for diarrheic lambs could decrease the incidence of pasteurellosis and reduce the mortality rate.</p> Omran E.
