Abstract

Thirty adults Desi and Khaki Campbell ducks were distributed to 6 farmers of Chakcharpur village of Mymensingh district. These ducks were subjected 3 types of mating e.g. Desi ${\times}$ Desi, Khaki Campbell ${\times}$ Khaki Campbell and Khaki Campbell ${\times}$ Desi-having 10 ducks (male : female = 1 : 4) in each mating group. Each mating group was then divided into two having 5 ducks(male : female = 1 : 4) and distributed to 2 farmers. After collecting eggs from each mating category, these were hatched by broody hens from which a total of 90 day old ducklings, 30 from each genotype were raised from birth to 90 days after the onest of laying. Although the weight of the day old chicks were similar in all genotypes (40-43 g), body weight was the highest (p <0.01) for Khaki Campbell ${\times}$ Desi (1,543) before the onset of laying followed by Khaki Campbell (1,552 g) and Desi (1,448 g) ducks. Khaki Campbell attained maturity at an earlier (p < 0.01) age (147 days) followed by Khaki Campbell ${\times}$ Desi, (154 days) and Desi (161 days) ducks. Khaki Campbell laid maximum (p < 0.01) number of eggs (46) compared to Khaki Campbell ${\times}$ Desi, (30) and Desi (18) ducks 90 days after the onset of laying. However, eggs were heavier (p < 0.01) in Desi (61.9) ducks compared to other genotypes. Fertility and hatchability were also higher in Desi ducks than the other two genotypes. Mortality was also lover in Desi ducks (3.33%) followed by Khaki Campbell ${\times}$ Desi (6.66%) and Khaki Campbell (16.66%) ducks. The results presented here indicated the superiority of Desi ducks over the other two genotypes with respect to egg weight, fertility, hatchability and mortality under village condition. Pure and crossbreds, on the other hand, were heavier at sexual maturity at relatively younger age and laid more eggs.
