Results show that number/doe of NF (23.8 vs. 16.6), HF (6.6 vs. 4.2) and total follicles (TF, 30.4 vs. 20.8) was higher (P0.05) and ovulation rate (OR) was lower (28.3 vs. 42.8%, P0.05) in Baladi than in MZW does. Number of CLs was 8.9 and 8.6/doe in NZW and Baladi rabbits, respectively. Average number/doe of NF, HF and TF was not affected by collection number. Average number of CLs/doe and OR increased (P0.05) by increasing collection number, being 7.6 and 27.1%, 8.8 and 35.6% and 10.0 and 41.3% with the 1. t, 2. d and 3. d collection, respectively. Average number of UVE/doe (1.9 vs. 1.3), TE (7.5 vs. 5.7) and ERR (87.0 vs. 64.0%) was higher (P0.05) in Baladi than in MZW does. The difference in number of NE/doe was insignificant between NZW (4.4) and Baladi does (5.6). Average number of NE and TE/doe and ERR was higher (P0.05) with the 1st (6.2, 7.3 and 96.1%) and 2. d (6.8, 8.3 and 94.3%) collections than with the 3. d collection (1.9, 3.7 and 37%). Average number of UVE/doe was 1.1, 1.5 and 1.8 at three successive collections. Such results may reflect the save side of embryo surgical recovery for two collections on number of embryos/doe and embryo recovery rate as a results of increasing number of UVE and ERR by increasing collection number up to three times.
