| dc.description | Bangladesh is an agricultural country where poverty alleviation is one of
the most important challenges of the twenty century. Agricultural
development is the main key to alleviate poverty from the country. The
livestock sector contributed 3 percent of gross domestic product (GDP), or
about 18 percent of agricultural GDP (DLS, 2006-2007). When the
indirect benefits of draught power and manure for fuel and fertilizer are
added to the direct economic output of meat, milk and hides, the value
added of the livestock subsector almost doubles, to about 6 percent of
GDP. The national herd comprises: 23 million cattle, 1.2 million buffalo,
20 million goat and almost 3 million sheep (DLS, 2006-2007). | en_US |
| dc.description.abstract | The present study was conducted for a period of 6 months with 375 cattle
(cows 278 and heifers 97) of five genotypes at sub-center (Artificial
insemination) of Upazila Livestock Office, Boda, Panchgarh of
Bangladesh to evaluate the effects of different factors on conception rate.
The experimental animals were inseminated artificially using the semen
from four genotype of bull. The overall feeding and management of the
animals kept by the farmers was almost similar. Effect of the factors like
genotype of cow, age of cow, milching or not, used for draught or not,
genotype of bull, efficiency of inseminator, site of insemination and time
of insemination on conception rate were determined. It was observed that
conception rate of the cows were significantly affected by the time of
insemination (P<0.01), site of insemination (P<0.01), inseminator (P<0.05)
and age of cow (P<0.05). On the contrary, there were no significant
(P>0.05) effects on conception rate by genotype of cow, milching or not,
used for draught or not and genotype of bull. The highest conception rate
was observed in the indigenous local cows (46.64%) of 5 years old
(51.63%) which were inseminated in the site of deep cervix (58.43%) with
the semen of LocalxHolstein-Friesian (F3) bull (47.00%) by experience
inseminator (54.26%) at 10-13 hours (52.34%) after onset of estrus and
cows in milching (45.32%) non-draught (53.62%) condition. It was
concluded that the age of cow, time of insemination, site of insemination
and inseminator were the most important factors to get maximum
conception rate of the cows. So, it may be suggested that to achieve the
desire rate of conception, the farmers should inseminated their cows in the
site of deep cervix by technically sound and skilled inseminator at 10-13
hours after onset of estrus. | en_US |
