| dc.description.abstract | This study was undertaken to compare the productive and reproductive performances of
crossbreds and Indigenous dairy cows that are available in char & plain land area of Ulipur
upazila under Kurigram District. In achieving this objective a sample of 96 dairy cows
(Indigenous & Crossbred) were selected randomly covering five villages of Ulipur upazila
in Kurigram District under Rangpur division of Bangladesh. A total of 96 dairy cows
belong to different breeds, such as 32 Sahiwal cross, 32 Holstein cross, and 32 Indigenous
cows were selected and their information regarding milk production and other
reproductive parameters were collected from individual farm family for a period of last six
months (June-November’2014). The numbers of animals of each of the genotypic classes
were 32 for Sahiwal cross, 32 for Holstein cross and 32 for Indigenous. Significant
differences were found within the milk yield (p<0.05), calving interval (p<0.05), service
per conception rate, (p<0.05), age at first heat, (p<0.05), gestation length (p<0.05) at plain
& char area (p<0.05). Average lactation yield, average lactation length and age at first
calving (Months) at plain & char area were found in no significant differences (p>0.05).
Highest milk yield (12.37 lit/day), age at first heat (20.5 months) and lowest calving
interval (533 days) were observed in Holstein cross at char land area. But in case of
Sahiwal cross, milk yield was (8.4 lit/day), age at first heat (24.5 months) and calving
interval was (561days). The lowest milk yield (1.84 lit/day), age at first heat (30.5 months)
and highest calving interval (684 days) were found in Indigenous cow. Production
performances of Holstein crossbred were superior to other dairy crossbreds. Sahiwal
crossbred was ranked in second.
Finally the study identified some problems of raising cows in the rural areas of
Bangladesh. These were scarcity of feeds and fodder, inadequate grazing land, lack of Veterinary Care and services, lack of availability of good quality bull, distance of AI
centers specially at char areas, lower conception rate, high price of feed and fodder, lack
of training and Extension and low price of milk. | en_US |
