Abstract: The aim of this study was to evaluate the effect of Yucca schidigera plant on rabbit reproduction parameters. Six weeks old New Zealand White rabbit females (n=36) and males (n=20) were used in the experiment. Animals in the control groups (C does; n=12 and C bucks; n=7) were fed with commercially available diet and the diet in the experimental groups was enriched with 5g/100kg (E1 does; n=12 and E1 bucks; n=7) or 20 g/100kg (E2 does; n=12 and E2 bucks; n=6) of Yucca schidigera powder extract. The rabbits were fed for 280 days and weighed weekly. The highest semen concentration was in the second experimental group E2 (3.80±0.57 x 109/ml) compared to control group C (2.84±0.33 x 109/ml) and experimental group E1 (1.9±0.35 x 109/ml). Semen motility (E2- 85.55±6.19 %; E1- 85.28±2.27% ) and progressive motility (E2; 73.45±9.63 %; E1; 71.16±3.43%) were higher in the experimental groups compared to the control groups (motility -78.69±5.17 %; progressive motility - 61.34±6.69 %).
The highest conception and kindling rate was found out in the control group C (83 % and 83 %, respectively), slightly lower values were reported in the both experimental groups E1 and E2 (for conception rate - 63% and 63%, respectively; and for kindling rate - 63% and 63%, respectively). Evaluation of the number of liveborn young rabbits showed, in the experimental group 2 the number of liveborn young rabbits (9.43±1.65) was higher than in the control (C; 8.0±0.97) and the experimental group 1 (6.0±1).
