The present investigation explored the important production and
fertility parameters of cows in the private "mini-dairy farms"
recently established in the district of Natore, Bangladesh. In
total, 313 cows were studied for fertility-related parameters
viz.interval between calving, onset of postpartum oestrus, open
days, days wasted and service/ conception with regard to the
ventilation and floor pattern of animals sheds, breed, body weight,
age, parity, health condition, feeding and reproductive disorders.
Proper ventilation, Concrete floor, Holstein-Friesian and Jersey
crossbred, Middle age-animals (5-7yrs), 4th parity, Heavier body
(301-401kg), Health condition (Grade-1) and Well balanced
concentrates (Grade-1) feed have shown improved the productivity
and fertility status of the cows, however the reproductive
performance was better in the selected local zebu cattle. In
average, 26.33% animals were suffering from different types of
reproductive disorders of which retained foetal membrane and
pyometra individually constituted (4.5%). In conclusions, the cow
of the mini-dairy farm has good fertility; however, the incidence
of reproductive disorders is alarming.
