\textbf{Abstract}
\begin{abstract}
\normalsize{
A wide array of parasites may infect non"=human primates that are often valuable in studies of either human disease processes or vaccine and drug development. At the Institute of Primate Research, baboons are used for biomedical research. They are models for diseases like Schistosomiasis, Malaria and even Reproductive biology. Assessment of gastrointestinal parasites of colony experimental baboon of different age and sex was done using non"=invasive technique to determine the identity; prevalence and intensity of these parasites since parasitic infections may affect animal health and ultimately the studies for which the animals are used. A total of 80 faecal samples were collected from 20 baboons: Four faecal samples were collected per week from each animal. Examination of these faecal samples through Direct smear method to detect trophozoites of amoebae and flagellates, Formal ether sedimentation technique for the identification of parasite eggs, cysts, and larval stages. Harada-Mori culture technique for identification of larvae from L1-L3 stage and MacMaster egg counting technique for intensity of parasite eggs per gram of feacal material. Four protozoan parasites (Balantidium coli, Entamoeba coli, Entamoeba histolytica and Giardia spp) and 3 nematodes (Trichuris spp, \textit{Oesophagostomum} spp and Strongyloides spp) were identified from the faecal samples collected. Entamoeba coli were the most prevalent protozoan among the sex and age groups of baboons with all the sexes and age groups having a prevalence rate of \mbox{100\,\%}. In nematodes, Trichuris spp and \textit{Oesophagostomum} spp had a prevalence of \mbox{100\,\%} in all the age group and sexes. Only one male adult and one female adult had one cyst count of Giardia. There was significant variation on the parasite intensity among age and sex group with   $p < 0.05$ for protozoan parasite. Trichuris spp had the highest intensity; no significant difference was observed between sex and age groups ($p > 0.05$). \textit{Oesophagostomum} spp, the male adults had the  highest intensity with low intensity recorded in male juveniles while the female adult and juvenile had equal intensity; there were significance difference of parasite between age and sex ( $p < 0.05$). Strongyloides spp female juvenile had a high intensity. }
