Effect of dietaryJatropha curcasseed meal on rabbits infested by adult ticks ofHyalomma marginatum marginatum

The objective of this study was to investigate the effectiveness of the oral administration of Jatropha curcas seed meal (JCSM) on serum biochemical parameters and histopathology of skin, liver, and kidney of rabbits experimentally infested by Hyalomma marginatum marginatum. Thirty healthy mixed-breed rabbits were randomly divided into five equal groups. The first group was kept as a control and fed soya bean meal. The remaining groups were fed diets containing 2.5%, 5%, 7.5%, or 10% JCSM. At the sixth week, each group was divided into two subgroups. Ticks were introduced to all members of one subgroup, the other subgroup being kept as control. Blood samples were collected and analyzed for biochemical parameters before (zero time) and after the treatment, on the 6th and 8th weeks. Histopathological studies were conducted 8 weeks after the treatment. The results revealed that JCSM could be used in the treatment of ectoparasites at levels of less than 10% in the diet without any serious effects on liver and...
