| dc.description | Poverty alleviation is one of the most important challenges of the 21* century in Bangladesh.
Agricultural development is the main key to alleviate poverty from the country. Livestock is
the most important agricultural component which alone contributes about 17.3% GDP to
agriculture (DLS, 2014). The contribution of livestock is very much important in developing
socio-economic condition. About 80% of our agricultural lands are cultivated by the help of
cattle (DLS, 2007). Many people of rural and new town areas use cow dung as fuel. Biogas
produced from cow dung is used for fuel and source of electricity. About 30-50% of rural
people depend on cattle rearing from employment (DLS, 2007). Now-a-days cattle rearing
have played a vital role in solving unemployment, youth problem and create income source
for rural women. In the past no emphasis was given for the development of cattle in the
Bangladesh. In spite of the cattle population in Bangladesh is considerably high (25.7
million) but the productivity is not satisfactory in terms of milk and calf crop production,
probably due to lack of appropriate breeding policy, feed scarcity, disease problem etc
(Banglapedia, 2012). To solve these problems partially, we have to improve local cattle
breed. As an appropriate breeding tool, artificial insemination has been used widely all over
Bangladesh. In Bangladesh, artificial insemination was introduced as an effective breeding
tool beginning of 1960 with the objective of upgrading indigenous local cows. In 1960,
Central Cattle Breeding Farm, Dhaka was established with the major objectives of
fundamental research in livestock and to evolve one or two cattle breeds suitable for the
country. Later, a cross breeding program was planned for upgrading the local cattle with the
infusion of Bos taurus blood (Miah et al., 2004). | en_US |
| dc.description.abstract | The aim of this study was to investigate the performance of artificial insemination on
conception rate in the dairy cattle available in Dinajpur, Thakurgaon and Panchagarh districts
and to evaluate the repeat breeding rate after artificial insemination by liquid and frozenthawed semen and also to study the calf production using liquid and frozen-thawed semen.
The present study was conducted from January-June/2014. The experimental data related
with the artificial insemination in Dinajpur, Thakurgaon and Panchagarh districts were
collected from District Artificial Insemination Centre, greater Dinajpur.
The yearly target of artificial insemination by liquid semen was higher (P<0.05) in the
Dinajpur District during all fiscal years. However, in 1% and 2™ fiscal years, it was
significantly higher in Dinajpur District than other two districts Thakurgaon and Panchagarh).
The first breeding by liquid semen was highest in the Dinajpur District during 1° to 4 fiscal
years and then decreased by Thakurgaon District in 5" fiscal year. The yearly target acquired
by liquid semen was higher in the Thakurgaon District (181%) during 1* fiscal year and then
remain consistent with Dinajpur and Panchagarh districts from 2™ to 5" fiscal years.
Similarly, in case of frozen-thawed semen, it was higher in the Panchagarh District (99%) at
1 fiscal year and then remains consistent with Dinajpur and Thakurgaon districts from 2™ to
5" fiscal years. The repeat breeding rate by liquid semen was higher in the Dinajpur District
during 1* to 4" fiscal years and then decreased in 5" fiscal year. But it was higher in
Panchagarh District (15.0%) in 5" fiscal year. The repeat breeding rate by frozen-thawed
semen was higher (P>0.05) in the Panchagarh District during all fiscal years. The pregnancy
number after artificial insemination with liquid semen was higher (P<0.05) in the Dinajpur
District during 1* to 4" fiscal years and remain similar with Thakurgaon in 5" fiscal year.
The conception rate was higher in Panchagarh District in 4" and 5" fiscal years. The
conception rate in this district was increasing year by year. On the other hand, the conception
rates achieved by frozen-thawed semen were almost similar during Ist to 4" fiscal years, but
differed in 5™ fiscal year. In 5" fiscal year, the conception rate achieved by using frozenthawed semen in Panchagarh District was higher (55%) than that of Dinajpur and
Thakurgaon districts. The male calf production by liquid semen was almost similar in the
Dinajpur and Thakurgaon districts during all fiscal years. However, the male calf production
by frozen-thawed semen was higher in the Dinajpur District than Thakurgaon and
Panchagarh districts during all fiscal years. Female calf production by liquid semen was
almost similar in the Dinajpur and Thakurgaon districts during all fiscal years. | en_US |
