Abnormal numbers of specific types of leukocytes may indicate immuno-suppression or immunocompetence in response to an immunomodulator. The objective of this study is to investigate the effect of feeding broilers on diet containing flaxseed on splenocyte Tand B- cells. Upon hatching, all chicks were given the same basal diet for 13 d. Dietary supplementation of flaxseed started at 14 d of ages until the end of the cycle at 35 d of age. At slaughter, samples of spleen were collected. Spleen cells were harvested in cell suspensions. Immune cells were then enumerated using the flow haemocytometer in the Physiology Laboratory. The overall differences between the dietary treatments were analysed using one-way analysis of variance (ANOVA) and the general linear model procedure of Minitab. Statistically, there was no significant effect of flaxseed on the percentage positive or mean fluorescence intensity of the leukocyte subsets under investigation. However, there was a trend towards an increase in the proportion of Bcells in the spleen after feeding 15 % of flaxseed, which approached significance (P=0.058). There was also a trend towards a decrease in the mean fluorescence intensity of CD8+ subsets in the spleen, which was close to statistical significance (P=0.054).This trend is particularly interesting, given the fact that the bursii in these chickens were significantly observed to be smaller and thinner. It suggests that flaxseed may either prevent the homing of B-lymphocytes to the bursa, or encourage the release of Blymphocytes from the bursa into the circulation and then in the spleen.
