The study evaluated the survival, live and carcass weight of 20 pigeons weighing 215g. The pigeons were divided into 4 groups. Groups 1, 2 and 3 were challenged with 0.2ml inoculum of 2.38×106 Trypanosoma (T) congolense, T. evansi and a combination of both respectively at 0.1ml each. Group 4 represented uninfected control. Their weights were measured weekly and carcasses of birds were weighed with a digital weighing scale. The survival was monitored daily for 63 days. Data generated were subjected to ANOVA, descriptive statistics and Duncan’s pos hoc test. Histogram charts were also constructed. Ethical approval was obtained from University of Jos. Results of carcass weight revealed significantly (P<0.005) higher values for groups 1 and 2 than 3 and 4. The live weight and survival were insignificant (P>0.05). The descriptive statistics showed that group 4 had the highest maximum live weight and group 3 had the least minimum live weight. The survival period revealed group 4 as having the maximum days while group 3 had the least minimum days. The weekly trend in live weights for all groups revealed fluctuating values from week 2 to week 5 while week 1 was same. The most declines in live weights for groups 1 and 2 were observed at week 4 while group 3 had the least decline in live weight at week 2. In conclusion, the work provided empirical evidences of the negative effects of trypanosomiasis caused by T. congolense and T. evansi in the domestic pigeon’s live, carcass weights and survival
