The objective of this work was to study the effect of Doum (Hyphaenethebaica) supplementation on productive and reproductive performance of rabbit does in Upper Egypt during spring season. A total of 6 months old 160 does including 80 California (CAL) and 80 Newzland (NEZ) rabbits with average initial body weight 3.150±0.05 kg was randomly divided into four groups of 20 does each/breed (CAL or NEZ). The study was conducted in a 4×2 factorial design. Doum in the basal diet was supplemented for each strain with 4 levels 0, 0.3, 0.6, 0.9 g doum kg diet and offered to 2 rabbit breeds New Zealand White (NZW) and Californian (CAL) in upper Egypt. Doum in the basal diet was improved performances of rabbits compared to control.  California does show significant higher productive and reproductive performances and lower mortality rate compared to the NEZ breed.
