  Data were collected from 10 different duck farm, five each of improved and local/deshi duck. The aim of the study was to evaluate biological and economic performance of improved and local duck farming depending on natural feed resources such as sanils, oyster, fallen paddy etc. in the beel area. Supplementary feeding is only practiced during scarce period. Egg production of improved duck per year was found to be double with comparison of local duck ffarming (200 vs 88). Season and availability of natural feed resources had a profound influence in egg production in this area. Average gross margin was Tk. (25099.61?885.64) and (5931?70.66) / farm/year for improved and local duck respectively and with benefit cost ratio of 2.66?0.08 vs 1.51?0.05. So economic analysis reveals that farming with improved ducks in beel area is more than that of local.

  Data in five parities of native cows were evaluated for per day milk yield, lactation length, birth weight of calves, post partum heat period, period of calving to conception, gestation length, calving interval and number of service per conception (nos.). Per day milk yield ranged from 2.23+0.48 to 2.62+0.43 liters in different parities. Likewise, lactation length and birth weight of calves ranged from 230.58+69.51 to 266.96+78.91 days and 20.44+3.15 to 21.88+3.19 kg, respectively among different parities. Post partum heat period and period of calving to conception ranged from 133.40+52.61 to 158.68+107.50 days and 162.16+72.49 to 212.88+125.50 days, respectively in different parities. Amongst the parity differences post partum heat period and period of calving to conception were not found to be significant. The mean gestation period during the fifth parity was shorter (p<0.05) than the first and second parities (274.50 vs 279.36 and 279.08 days, respectively). Calving interval and number of service per conception ranged from 445.44+75.04 to 487.40+130.36 days and 1.48+0.77 to 1.88+0.10 numbers, respectively over the parities. But there was no difference on the parameters like calving interval and number of service per conception over the parities.
