| dc.description | Bangladesh is a densely populated agriculture based country with 154 million people and
positioned currently 8"" among all the countries of the world (UNFPA, 2012). The human
population growth in developed countries is stabilizing while that of developing countries
including Bangladesh is increasing rapidly. According to the World Bank information (2012),
Bangladesh ranked 61 (in 2011) in respect of human poverty. The depth and severity of
poverty is worse in rural areas, 80% of the total population lives in the rural areas that
primarily depend on a poorly developed agriculture for livelihood (BBS, 2014). The domestic
production of milk, meat and egg are 3.46, 2.33, and 7303 million tons in the 2011-2012
fiscal year against the demand of 13.50, 6.48, and 15392 million tons, respectively (Hossain,
and Hassan, 2013). There is a deficit of milk (80%), meat (82%) and eggs (63%), (FAO,
2008). Due to the severe poverty most of these people faces an acute deficiency of animal
protein sources, like meat, milk, egg etc. Among the livestock sector, the poultry industry
was becoming a leading industry in our country. But unfortunately, the industry is in the line
to be destroyed due to severity of avian influenza (bird flu). Thus, it is crying need to search
the alternative protein source to meet up the increasing demand. | en_US |
| 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 (PGF a) injection, intra-vaginal washing with acetic acid and combination
of prostaglandin (PGF2a) 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. PGF2a (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 PGF2a 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 |
