Abstract
Series
of experiments were conducted at the Abubakar Tafawa Balewa
University Farm, Bauchi, Nigeria to investigate the reproductive
performance of local and exotic rabbits. For the local and
exotic rabbits, the mean (+ S.E) gel-free volume, gel
volume, progressive motility, sperm concentration, total sperm
per ejaculate, % live spermatozoa and % abnormal spermatozoa
were 0.61 + 0.02 vs 0.80 + 0.01ml; 0.37 +
0.02 vs 0.48+ 0.01ml; 65.42+ 0.68 vs 71.83 +
0.70; 74.47 + 0.50 vs 101.00+ 0.34 x 106;
45.66+ 1.45 vs 80.75+ 1.68 x 109; 73.95+
0.86 vs 85.48+ 1.00% and 17.23+ 0.23 vs 13.84+
0.21% respectively, and were significantly (P< 0.05) different
between the breeds. The results also showed that kindling rate
(11.80 vs 14.71), number of young born (14.0 vs 22.0) and mean
litter size (3.5 vs 4.4) for local and exotic rabbits
respectively, and did not differ significantly between the two
breeds. The Dutch rabbits are superior to the local ones in
terms of their reproductive performance, and could be used to
upgrade the local breeds. It is also suggested that when
conducting AI in rabbits, appropriate method of ovulation
induction should be opted for in order to achieve maximum
conception rate.
Key
words: Rabbits, ejaculate
characteristics, ovulation induction and teaser bucks.
