Publication Description :

Previously we have shown that poor reproductive performances of buffaloes are linked with poor breeding and other management practices in certain coastal areas in Bangladesh. The aim of the present study was to determine the effect of the parity as an important trait on productive and reproductive status of nondescript type buffaloes reared under subsistence farming conditions at selected coastal districts in Bangladesh. Data records for lactation length (LL), milk yield per day (MY/d), calving interval (CI) and dry period (DP) through a pre-tested questionnaire on 220 buffaloes were collected, analyzed and evaluated. Parity did not significantly affect milk yield per day (MY/d) and dry period (DP), but had a significant effect on lactation length (LL) and calving interval (CI). The lactation length (LL) was found significantly higher in the first parity (181±0.67 days) compared with that of the second and third parity (172±1.14 and 178±1.02 days, respectively). Furthermore, calving interval (CI) was significantly higher in first lactation (496±0.29 days). It is concluded that as the parity significantly correlates with calving interval (CI) and lactation length (LL) of buffaloes, the Buffalo’s breeders/owners may consider the parity, calving interval (CI) and lactation length (LL) together with milk yield (MY/d) and dry period (DP) in management programs as important parameters for selecting breeding buffaloes which eventually may greatly contribute in farm productivity and profitability in the selected coastal areas.
