Abstract/ Executive Summary:

Three-month-old 600 ducklings of Khaki Can bell/KC Desi and KC X Desi were reared for a period of 13 months in the villages surrounding Bangladesh Agricultural University in order to study the economic traits of duck with and without extra feed to scavenging system of rearing. KC attained earlier sexual maturity followed by KC X Desi and Desi ducks and crossbred showed closeness to sire breed for this trait, KC X Desi found heavier and produce more eggs than their parental breeds. KC showed higher hatchability followed by KC X Desi and Desi ducks were more resistant followed by KC X Desi and KC to diseases. Extra feeding were found more beneficial to ducks irrespective of breed and types.

Objectives:

To envisaged the performance of Khaki Can )bell, Khaki Can )bell X Desiand Desi ducks under the rural condition of Bangladesh with and without supplementary feeding.

Methodology:

The experiment was conducted in the villages surrounding Bangladesh Agricultural University (BAU). Layout of the experiment: Three months old 200 Khaki Can) bell (40 males and 160 females), 200 Desi (40 males and 160 females) and 200 Khaki Can bell X Desi (40 males and 160 females) ducks were randomly distributed among 120 previously selected farmers at the rate of 1 male and 4 females for each farmer and reared on with and without supplementation of feed for a period of 13 months. Each breed belonging to each feeding regime had ten replications. The breed type was distributed at random to the farmer i.e. one farmer got either of one breed ducks in each group were identified properly and provided with identical care and management All ducks were maintained under free-range conditions. In case of ducks on supplementary feeding, they were provided with supplementary feed on scavenging. The feed supplied composed of locally available feed ingredients, about 50 g of wheat per bird per day and occasionally about 20 g of dry fish. Birds of all groups were allowed to obtain their feed by scavenging routine vaccination and deworming programmes were taken for the prevention of diseases. Broody hens were used to incubate eggs collected from the 3 breed types-to record hatchability parameters. The following records were kept during the experimental period to fulfill the objectives: (])Age at sexual maturity determined by the first egg laid by the ducks (2) Age at 50% egg production (3) Age at peak egg production (4) Bodyweight at sexual maturity, at peak production and at the end of ten months laying period (5) Egg production upto 10 months of laying period, daily group-wise record (6) Hatchability of egg for each replicate (7) Mortality was recorded daily for each replication The data collected on various parameters were analyzed for a 3 (breeds) X 2 (feeding) regime, factorial design.

Achievement/Findings:

Age and body weight at sexual maturity, 50% egg production and peak egg production. Khaki Carrpbell (KC) reached sexual maturity, 50% egg production and pe k egg production at an earlier age followed by Khaki Can?bell X Desi (KC X Desi) and Desi ducks respectively. In all those mentioned parameters birds on feed supplementation exceeded those on scavenging without feed supplementation (p < 0.05). The age at sexual maturity, age at 50% egg production and age at peak production were more influenced by the sire breed, KC. Weight gain was highest in KC X Desi followed by KC and Desi ducks respectively (p < 0.05). Provision of supplementary feeding increased live weight by about 7% in KC, 14% in KC X Desi and 9% in Desi Ducks (p < 0.05). Breed differences in live weight was widened in supplementary feeding (p < 0.05) in all these parameters, i.e. breed and feeding regime interacted upon these traits. The crossbred showed heterosis in live weight gain and they exceeded the average of the parental breed in weight gain. Moreover, increase in body weight gain due to supplementary feeding was more profound in the case of crossbred than that in pure breed ducks (p < 0.05). The superiority of crossbred over the parental pure breeds for weight gain were found at all stages of growth. KC X Desi ducks laid 64% more eggs than the KC ducks and KC ducks laid 63% more egg than the Desi ducks. An increase of about 51% in egg numbers were obtained from birds receiving supplementary feeding. Egg production in crossbred ducks receiving supplementary feeding were more higher than the parental breeds. Breed and feed acted independently in egg production traits. Hatchability: Egg hatchability in KC was highest followed by KC X Desi and Desi ducks. Ducks receiving supplementary feed had 3.82% higher egg hatchability. Breed and feed effects were independent on egg hatchability. Mortality: Mortality of ducks was highest in KC, intermediate in KC X Desi and lowest in Desi ducks. On the other hand, supplementary feeding decreased mortality by about 54.7% on average. Breed and feed were independent in action on mortality.
