Abstract |
This work was designed to study the reproductive performance, physical semen characteristics and economical efficiency for New Zealand White (NZW) rabbits fed diets containing peanut vines hay (PNVH) or peanut vines silage (PNVS), which replaced different levels (0, 50, 75 and 100%) of clover hay (CH) in the mixed rations. Fifty -six (42 does + 14 bucks) NZW rabbits 22 weeks old with an average live body weight of2.8 to 3.0 kg were used. Seven equal groups (6 females + 2 males) of rabbits were allotted to the different experimental rations. During reproductive period, does and bucks were housed separately in individual cages. Conception rate, litter size at birth and bunny weight at 14,21,28 and 35 day were determined. Semen was collected 3 times during the last month of experiment through the artificial vagina. Some semen characteristics were examined. The results for the first kindling indicated that, average conception rate for NZW does ranged from 83.33 to 100.00%. While, average of bunny weight gain at 35 days (at weaning) ranged from 25.14 to 32.14 g/day and mortality percentage during all period ranged from 9.53 to 24.77%, with significant differences (P < 0.05). In the second kindling, reproductive performance decreased compared with the first kindling. The differences in doe and offspring traits were not significant except for bunny weight at birth, weight gain at 21 and 28 days of age which were significant (P<0.05) among dietary treatments. Mortality percentage was higher compared with the first kindling. The results of semen characteristics indicated that, ejaculate volume, sperm motility, pH value and sperm concentration were not significant (P<0.05) for bucks fed rations which contained different levels of PNV as hay or silage. Concerning the economical efficiency of reproductive performance, the rabbits fed R7 (containing 100% PNVS) recorded the highest values for economical efficiency and relative economic efficiency as compared to control (713.20 and 177.57%, respectively), with significant differences (P<0.05) among treatments.
Keywords: peanut vines, rabbits, reproductive performance, economical efficiency.
