Abstract/ Executive Summary:

A total of 198 straight run day old ducklings of Bangladesh Livestock Research Institute (BLRI) developed native duck (named as Rupali and Nageswary) and local native duck genotypes were distributed among nine farmers of low laying areas of Kalihati Upazilla of Tangail district. Rupali and Nageswary ducklings were obtained from existing stock of BLRI and local native ducklings were collected from local farmers of the study area. After 12 weeks of age each farmers retained 10 female and 2 male ducks and sold away remaining ducklings. Farmers’ were instructed to supply 50g of balanced feed to their ducks in the morning and evening. Ducks were allowed to scavenge in the beel throughout the day. Data on: growth, feed intake, age at onset of lay, egg production rate, egg weight, mortality rate were recorded and cost-benefit was calculated. There found no significant difference on growth parameters, live weight gain, age at first laying or age at peak egg production among the duck genotypes. In the study highest live weight gain was found in Nageswary (1090 g) followed by Rupali (1058 g) and local native (912 g) duck at 8 weeks of age. Egg production rate of local native ducks (37.21%) was found significantly lower (P<0.001) compared to Rupali (50.67 %) and Nageswary (55.40 %). The mortality rate in local duck was significantly higher (P<0.05) compared to Rupali and Nageswary ducks. Rupali ducks produced heavier eggs (66.86g) followed by local native (62.20g) and Nageswary (57.22g) which differed significantly (P<0.05). Rupali ducks laid eggs of thicker shell (0.61mm) compared to other duck genotypes under study which was also varied statistically (P<0.05). Cost benefit analysis shows that earning both from Nageswary and Rupali was much higher than local native ducks. Higher egg production rate of Nageswary and Rupali duck has contributed for higher return. It is concluded that rearing Rupali or Nageswary ducks in the low laying rural areas with scavenging and supplementary feeding facility is more profitable than rearing local native ducks.

Objectives:

To validate the production ability of Rupali and Nageswary ducks compared to locally rear native ducks under farmer’s condition.

Methodology:

The experiment was conducted in a low laying area of Kalihati Upazilla of Tangail district in Bangladesh from April 2011 to June 2012. A total of 198 straight run day old ducklings of Rupali, Nageswary and local native duck genotypes were distributed among 9 farmers. The experiment had 3 treatments and each treatment group have 3 replications. Each replication consisted of 22 ducklings either of Rupali, Nageswary and local native duck respectively. Local native duck group was considered as the control group. All birds received supplementary feed in addition to scavenging feed. The experimental designed was completely randomize design (CRD) and data were analyzed using one way ANOVA in SPSS computer program. Farmers were brooded their ducklings according to their own practice up to 28 days of age keeping in confinement and fed on balanced duck starter feed containing 20% crude protein and 2800 kcal energy/kg diet along with home grown feed like rice polish and kitchen waste. Before distribution of ducklings farmers were trained on improved feeding management and hygienic techniques. Ducklings were vaccinated against Duck plague and Duck cholera at 28 days and 60 days of age, respectively and booster of both the vaccine were administered one week later of initial dose. After 28 days of age the experimental birds were allowed to scavenge freely in the natural water body from 8.30 A.M to 4.30 P.M. At the end of 12 weeks of age male and female ducks were separated by the farmers. Each farmer retained two drakes and 10 ducks and, sold away remaining birds. Up to 28 days of age ducklings were fed ad libitum on duck starter and home grown feed and in the next 4 weeks the continued on starter feed along with scavenging feed resource in the water bodies. Thereafter only 50g of balanced duck feed (grower feed up to 20 weeks of age and then layer feed) were supplemented along with scavenging. The native ducks can support 30-40% of their nutritional requirement from scavenging feed resource base. Based on that information it was assumed that supplying 50g of balanced feed (about 33%of daily requirement) and allowing the ducks to scavenge in a water body may support production of ducks under study. Supplementary feed was supplied from BLRI, which was prepared as per nutritional recommendation of Ferrell and Stapleton. Supplementary feed was divided in to two equal portions and was given twice daily at morning and evening. Feed was supplied in the plastic bowl and the bowls were cleaned properly before each feeding. Data were recorded on growth, feed intake, age at onset of lay, egg production, egg weight, mortality and economic return of ducks. A research assistant performed record keeping with the help of collaborator farmers.
