Abstract:

The purpose of this study was to investigate changes in serum concentration of copper, zinc, and calcium in sheep naturally infested with lice (Bovicola caprae, Linognathus africanus, Linognatus ovillus, and Linognattus pedalis). Twenty sheep naturally infested with lice and 20 healthy sheep were used as subjects. Blood samples were collected from the sheep before and 8 and 15 d after treatment with Avermectin, a veterinary antiparasitic drug. The samples were analyzed for their serum copper, zinc, and calcium concentrations by atomic absorption spectrometry. The concentrations of these elements in the infested animals were lower than in the healthy controls, mainly because the general condition of the affected sheep was poor. When the infested animals were treated with an ectoparasitic drug, the serum levels of the studied elements rose to normal ranges while the health of the animals improved.
