Broiler breeder stocks are characterised by low egg fertility and hatchability which could be mitigated by dietary Vitamin E (VE) supplements. The optimum vitamin E requirements for efficient production by Arbor Acres plus broiler breeder hens in Ibadan were investigated in this study. Arbor Acres plus broiler breeder hens (n=180) weighing 3.85 ± 0.49 kg, aged 30 weeks were randomly allotted to diets supplemented with synthetic VE at 0, 20, 40, 60, 80, 100 IU/kg for eight weeks in a completely randomised design. Hatchability of 86.4 ± 1.9% in hens fed diets supplemented with 100IU was significantly lower (p<0.05) than in those on 0 (93.3 ± 1.8%), 20 (92.9 ± 2.0%), 40 (96.9+1.5%), 60 (93.2 ± 0.9%) and 80 IU (91.2 ± 1.7%). Weight of 42.9 ± 1.3 g in chicks on 40 IU was significantly higher (p<0.05) than 36.9 ± 1.5 g (0IU), 40.2 ± 1.3g (20IU), 39.1 ± 1.2 g (60IU), 40.0 ± 0.6 g (80IU) and 39.3 ± 0.6 g (100IU). The relationships between VE inclusions and hatchability (R2=0.63); and chick weights (R²=0.56) were quadratic and cubic, respectively. Optimal egg hatchability of 94.8% and chicks’ weight of 41 g were achieved with diets supplemented with 37 IU/kg and 24 IU/kg supplemental VE inclusions, respectively. Thus, the dietary supplement of vitamin E enhanced the fertility and hatchability of Arbor Acres plus breeder broiler hens in Ibadan, Nigeria.
