Performance of BLRI developed native duck under farmer’s condition with supplementary feeding

Abstract

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.

Performances of Nageswari duck of Bangladesh under intensive management condition

“…The average egg weight was estimated as being 58.20 ± 1.50 g in the present study (Table 3). This result is in accordance with the findings of Khatun et al (2012) who reported average egg weight to be 57.22 ± 1.89 g in Nageswari ducks.…”

“…This result is in accordance with the findings of Valavan et al (2009) who reported average annual egg production to be 200-220 in Nageswari duck under intensive management system. Khatun et al (2012) found 55.40 ± 2.36 % egg production rate up to 52 weeks of age in Nageswari duck which is relatively lower than the present study (60.19 ± 3.63) considering the same age of hen day egg production.…”

“…On the other hand, Islam et al (2014) found the average weight (36.24 ± 2.90g) of day old Nageswari duckling which was little lower than the present findings. However, Khatun et al (2012) reported 8 th week live weight of Nageswari duckling was observed to be 1090.06 ± 122.84g at farmer's level with supplementation which is little higher than the present study.…”

“…Relatively lower egg production per year (120 to 150 numbers) of Nageswari ducks under scavenging conditions in Assam (Islam et al, 2002;Sharma et al, 2003 andZaman et al, 2005) was recorded compared to Valavan et al (2009) who found more than 200 eggs per year under intensive management condition. Khatun et al (2012) reported egg production rate of Nageswari duck up to 52 week of age was 55.40 ± 2.36% under farmer's condition of Bangladesh. On the contrary, indigenous ducks of Bangladesh are low productive, lay only 60-80 eggs per year (Rahman et al,2009;Pervin et al, 2013).…”
