It is imperative to know the reproductive parameters of the existing swine breed for profitable farming in Bangladesh. This study was designed to determine the reproductive parameters of sows at hilly areas. A total of 245 pigs with47 breedable sows were included. The data on age at puberty, oestrous cycle length, oestrus duration, gestation length,interval between furrowing and onset of oestrus, first service pregnancy rate, service per pregnancy and number ofpiglets born per sow in local and cross bred sows were determined. The present study revealed that age at pubertyof local and cross breed sows was 232.5 ± 8.4, 221.3 ± 6.9 days, respectively. Oestrous duration was 41.1 ± 3.1 hours. The interval between furrowing and onset of oestrus was shorter in cross bred sows. There was no variation in valuesof oestrus cycle length and gestation length. The first service pregnancy rate was higher in both the local and crossbred sow. Number of piglets per sow per farrowing was 6.1 ± 2.2 and 60.9% local sows gave birth of 3 to 5 pigletsper farrowing whereas 75.0% cross bred sows gave birth of 6 to 9 piglets. These results suggest that reproductiveparameters of local sow need to be improved for better production, and cross bred sows should be reared for obtainingexpected productivity.
