The objective of this study was to evaluate the effects of adding nano Zn Fitogenik (NZF) on broiler diet to carcass traits, relative organ weights and haematological indices. This study used 360 heads of sexed Lohman broilers day old chick (DOC). The experimental design used was a complete design with 6 (six) treatments and 5 (five) replications, each experimental unit consisted of 12 DOC (6 males and 6 females). There were the treatment given in this study; R1 = basal diet; R2 = R1 + Zn Sulfate (90 mg Zn kg −1 ) + 5.32 mg kg-1 guava leaf flour; R3 = R1 + NZF (45 mg Zn kg −1 ); R4 = R1 + NZF (90 mg Zn kg −1 ); R5 = R1 + NZF (135 mg Zn kg −1 ); R6 = R1 + NZF (180 mg Zn kg −1 ). At 33 days old age, one male broiler from each experimental unit was slaughtered and observed for carcass weight, abdominal fat, visceral organs, and digestive tract. Haematological evaluation using 30 blood samples were taken from each experimental unit. The results showed that addition of NZF at a dose of 90 mg Zn/kg (R4) improved weight of carcass, heart, and ileum. The addition of NZF at a dose of 135 mg/kg (R5) increased the number of erythrocytes when compared to the treatment group without the addition of NZF (R1). Adding NZF tent to decrease H/L ratio. It can be concluded that adding NZF imporoved carcass weight and tend to suprisse heat stress in broiler.
