Infestation rate of lice on donkeys in Northeast Tunisia
2020
The present survey was carried out during autumn 2013 (September, October and November) in five localities of Jendouba district. A total number of 300 donkeys were examined and all present ectoparasites found on animals were collected and examined under stereomicroscope. The infestation rate by lice was estimated to 12.7% (38/300) there was no difference between infestation rates in males (11.5%; 22/192) and females (14.8%; 16/108). The highest infestation rate was observed in donkeys aged between 10 and 14 years, they represented 19.6% of the infested donkeys. Two lice species were collected with no statistically difference between the two infestation rates: Haematopinus asini (4%; 12/300) and Bovicola ocellatus (5.3%; 16/300). The lice were collected from donkeys of the five regions with no statistically difference between the infestation rates.A specific programme to control these parasites is recommended to improve the welfare of the working donkeys in Tunisia and in other North African countries.
