| dc.description.abstract | This study was carried out with New Zealand (White, Black and Brown) rabbit to improve
the reproductive efficiency of does using hormonal and acetic intra-vaginal washing
treatments. Three experiments were conducted from March to September, 2014 in the Rabbit
Farm under the Department of Genetics and Animal Breeding at Hajee Mohammad Danesh
Science and Technology University, Dinajpur, Bangladesh. Under the experiments the effect
of prostaglandin (PGF2α) injection, intra-vaginal washing with acetic acid and combination
of prostaglandin (PGF2α) and Gonadotropin Releasing Hormone (GnRH) injection were
observed. The traits: conception rate, gestation period, litter size (at birth and weaning), litter
weight (at birth, at 7, 14, 21 and 28 days of age), individual kit weight (at birth, at 7, 14, 21
and 28 days of age), mortality rate of kits, live weight gain of rabbit does during the
experimental periods were evaluated and post mortem examination of productive and
reproductive organs of low fertile and infertile rabbit does were performed. PGF2α (supplied
by Techno Drugs Ltd. Bangladesh) injection did not affect conception rate, gestation period,
litter size at birth and weaning, litter weight from birth to weaning, individual kit weight from
birth to weaning, kit mortality, doe live weight gain. Intra-vaginal washing with acetic acid
increased (P<0.05) conception rate, litter size at birth, litter weight from birth to weaning, kit
mortality, doe live weight gain. However, the combined use of PGF2α and GnRH (Bayer,
New Zealand) increased (P<0.05) conception rate, litter size, litter weight from birth to
weaning, individual kit weight from birth to weaning, kit mortality, doe live weight gain. | en_US |
