Experimental Study On Sheep Infested With Bovicola Ovis And Melophagus Ovinus Of Pathological Changes Processed Skin Defect And Effect Of Treatment In Improving Skin Quality

Experimental study was conducted from January, 2015 to August, 2015 on sheep experimentally infested by B .ovis and M. ovinus with the objective of identifying specific pathological changes they induce, the type of defect at pickle and their effect on skin quality and effect of treatment on resumption of skin to normal state. For this purpose, thirty indigenous sheep of Arsi origin approximately 18 months age were bought from market. They were treated against infection and parasites and kept for a month to stabilize them before the commencement of the experiment. The sheep were then grouped in to five groups each with six individual sheep as non-infested control, B .ovis infested untreated, B .ovis infested treated, M. ovinus infested untreated and M. ovinus infested treated. B .ovis and M. ovinus were manually collected from donor sheep; identified, counted and then infested at 500 B .ovis and 50 M. ovinus per sheep to the respective treatment groups. All groups were managed under similar condition and followed for 95 days and Sheep within the infested treated groups were treated with diazinon and followed for additional 30 days. The total WBC count was increased in B .ovis and M. ovinus infested groups compared to non-infested control group. However, the statistically significant was only for groups infested by M. ovinus (P< 0.05). In all infested groups the differential leukocyte count was increased; nevertheless, the significant difference was only for eosinophil (P
