| dc.description.abstract | Duck population in Bangladesh has been reported to be 45.12 million (BER 2012) mostly of indigenous type
although genetic dilution in some regions has occurred due to distribution of high yielding breeds or strains. Khaki
Campbell duck being an important poultry species can contribute efficiently in increasing egg and meat production
in the Kuliarchar Upazilla, Kishoreganj district. The study was carried out in Kuliarchar upazilla, Kishoreganj
during the period of August 2014 to May 2015. A total of 120 female day-old ducklings (Khaki Campbell) were
procured from the local farmer from Kuliarchor Upazilla. The ducklings were randomly distributed into 4 treatment
groups that is group A, group B, group C and group D (untreated control). Group A, group B, and group C were
treated by Digester
respectively which is marketed by ACI animal health Limited.
Digester

, Vitapoultry

, Alqurzim

is one of the best vitamin and
mineral premix which enhance the growth rate, egg production as well as meat production of the poultry. Alqurzim
®
is a probiotics which enhance the growth of the animal. Vitapoultry
®
®
helps in improving the digestibility of the poultry. All ingradients were supplied 2g/kg feed daily. The individual
body weight of ducklings was recorded. Body weight was increased day by day with the helping of feed additives.
Digester
had direct effects on the growth of ducklings. The weight was higher in group B
treated by Vitapoultry

in every stage of weighing compare with other. The body weight of control group was lower
than the treated group. There was a significant (p<0.01) difference between the treated group and control group.
The
egg production of Khaki Campbell ducks recorded at 24-28 weeks, 28-32 weeks, 32-36 weeks, 36-40 weeks of age
at group A, group B, group C and group D were 19.70±0.64, 19.78±0.61, 18.76±0.56, 18.51±1.25; 22.81±0.67,
22.67±0.70, 23.56±0.87, 21.56±0.67; 18.44±0.45, 20.09±0.38, 17.91±0.56, 17.62±0.26; 14.61±0.69, 15.83±1.65,
15.16±0.46, 14.42±0.79 number respectively. There was a significant difference (p< 0.01) between the treated
group and control group in 32-36 weeks of age.
The weight of the egg of treated group was higher than the control
group. The onset of puberty of Khaki Campbell recorded at group A, group B, group C and group D were
®
23.9±0.12, 22.54±0.17, 23.14±0.57, 24.14±0.61 weeks respectively. The fertility of egg (%) of Khaki Campbell
recorded at group A, B, C and D were 83.78±0.57, 85.44±2.46, 84.28±0.24 and 78.49±2.74 respectively. The
Hatchability (%) of Khaki Campbell recorded at group A, B, C and D were 67.27±8.09, 68.16±7.68, 64.94±0.97,
58.85±3.83. The hatchability (%) highest in treated groups compared with the control group. Feed additives had
tremendous result both productive and reproductive performance of Khaki Campbell duck compared with control
group in Kuliarchar Upazilla, Kishoreganj district. Specifically Vitapoultry
had very good result when mixed with
the basal feed and provided daily to the duck. So, my recommendation is to use viatamin, mineral and amino acid
containing feed additives with basal feed for enhancing the productive and reproductive performance not Khaki
Campbell but all other breeds of duck in Bangladesh. Further studies need to develop an appropriate implementation
of using feed additives with basal feed in ducks in Bangladesh.
