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 ...

Natural Killer (NK) cells are large granular cytotoxic lymphocytes that play a role in the innate immune response against tumour cells and virally infected cells. In pathogen-free chickens, these cells are thermolabile at 37oC and resistant to treatment with anti-B or anti-T cell anti-sera. This is in contrast to humans and rats, where NK cells are resistant to temperature manipulation for 30 or 60 minutes. While some reports suggest that NK cells are adherent and phagocytic, others suggest they are non-adherent a...
