A study was conducted to examine and compare the hematological changes associated with single or mixed infection of Trypanosoma brucei and Trypanosoma congolense in Landrace pigs. 20 gilts between 3-5 months and with an average weight of 18.26kg were divided into 4 groups (Group 1 - Trypanosoma brucei infected; Group 2 - Trypanosoma congolense infected; Group 3 mixed Trypanosoma brucei and Trypanosoma congolense infected; Group 4 - Uninfected control). Onset of parasitaemia was 8, 9 and 12 days post infection (pi) for groups 1, 2 and 3 respectively. During the course of infection, there was a statistically significant (P < 0.05) increase in body temperature between group 2 and 3 and group 4, and decrease in body weight between the infected groups and control. Significant decrease (P
