The present study covered the abundance of lice on goats, and their effects on animals health, liver as well as kidney functions. Three lice species infested goats, one species was that of biting lice Bovicola caprae(Gurlt) which belonged to order Mallophaga and the other two species were those of blood sucking Linognathus africanus (Kcllogg and Paine) and L.stenopsis (Burmeister) of the order Anoplura. The experimental study was carried out on goats at Mariut experimental 
station of the Desert Research Center. Goats were divided into two groups, onc (25) was free of lice and the other (27) was heavily infested. A heavy degree of infestation resulted ina highly significant reduction of blood glucose. A highly 
Significant increase occurred in plasma parametcrs Alkaline Phosphatase (ALK.Phs), total Bilirubin, Alanine aminotransferase (ALT) and Aspirate aminotransferase (AST). Also, in high infested goats a highly significant increase in 
serum urea and creatinine was reported. From the results encountered highly infested goats with lice it was suggested that some liver and kidney cellulars damage might have occurred. Heavily infestation levels were of considerable
on goats, and their effects on animals health, liver economic importance.
