This study was conducted to determine the effects of different levels microalgae Chlorell sp. on performance of laying hens under heat stress condition. A completely randomized design experiment, with 7 replicates and 6 treatments (9 birds per replicate) was carried out by allotting 378 white Lohman strain laying hens at 65 weeks of age. Six experimental treatments were continual addition of 0, 100, 200, 300,400 ppm microalgae Chlorell and 400 ppm toein to drinking warer were fed to laying hens for 9 weeks. Egg production, egg weight, egg mass output and feed intake were determined. Antibody production against sheep red blood cells (SRBC) also was measured. Data  were  analyzed  by  ANOVA  using  General  Linear Models procedure of  SAS software and comparison of means  were  compared  using  Duncan’s  multiple  range test. The results of this experiment showed that microalgae Chlorell had no effect on productive performance. Adding microalgae Chlorell to the drinking water improved immune response of laying hens and a more positive effect was observed when 400 ppm added to the water. It is concluded that the addition of microalgae Chlorell to the water drinking of laying hens improved immune response of laying hens.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12058 International Journal of Life Sciences 9 (2) : 2015; 71-74
