• Maintained and evaluated Khkai Campbell, White pekin, Desi (native) and Moti ducks
  • Comparative evaluation of Khaki Campbell(K), Desi(D) and their two reciprocal crosses (DK and KD) for duck day egg production up to 72 weeks of age revealed that DK crossbred produced highest eggs (220.09) followed by KD (188.42), K (170.45) and D(165.23) with egg weight of 70.22, 70.18, 69.64,72.38 g in D, K, KD and DK, respectively. Significant difference was observed for body weight and egg weight at different age of measurements between the genetic groups. Haugh Unit calculated at 72 weeks of age in D, K, KD and DK were 86.23, 91.03, 92.13 and 91.35, respectively.
  • A 3X3 diallel crossing involving Desi(D), Khaki Campbell(K) and White Pekin (W) duck breeds showed significant differences for egg weight, body weight at 40 and 60 weeks of age between differenet genetic groups. Mortality per cent from 20 to 60 weeks of age was less in crossbreds than in the purebreds. The egg production and mortality in differrent genetic groups revealed that for dual purpose bird DW cross was found the best and for laying type DK was the best cross.

• Parent lines of coloured plumage dual purpose chicken stock viz CARI Debendra are being maintained at Regional Centre, Bhubneswer for popularization in the region. This bird thrived well in intensive, semi-intensive and extensive poultry farming systems in villages of Odisha. The body weight at 20th week was 2596.38 and 2054.86 g in intensive and extensive system of rearing, respectively. The egg production recorded upto 60th week was 156 and 123 eggs on hen day basis in intensive and extensive system of rearing, respectively.

• Nutrient requirements of ducks.
• A diet with 22% CP and 2700 kcal ME/kg was found optimum for growth and feed conversion of native ducks during 0-8 wk of age.
• A diet with 16% CP and 2500 kcal ME/kg was optimum for growth and feed conversion of native ducks during 9-16 wk of age.
• During layer stage the ration containing 18% CP and 2750 kcal ME/kg was optimum for egg production.
• Utilization of cassava(Manihot esculent crantz)
• Maize can be replaced by Cassava tuber meal upto 40% without affecting the performance of the broilers.
• Detoxification of  cassava tuber meal by soaking and drying had no additional effect on nutrient utilization.
• Maize can be replaced by Cassava tuber meal upto 100% without affecting the performance of the White Pekin ducks.

• Identification and utilization of available feed resources for backyard poultry rearing
• Different feed ingredients consumed by the birds from backyard system of rearing were identified and their nutritive values determined.
• Protein deficiency to the extent of 7.6 to 11.8% was observed in the diet of birds consumed from free range system.
• Supplementation of critical inputs during early stage of brooding and laying period showed beneficial results.
• The women of the small, marginal and landless labourer families take care of most of the activities of backyard poultry rearing.
• Further study is required to assess the production potential of dual-purpose birds in the backyard system of rearing. 

• Addition of vitamin E and selenium in duck feed to certain level increased egg production, fertility and hatchability.

Appropriate health coverage provided brought down the average annual mortality of ducks to 9.34 %. Month- wise highest mortality was found in April (38.74%) and lowest in March (0.39%). Major cause of mortality was due to enteritis (19.83%) followed by predation (17.93%), debility (14.94%), septicemia (14.13%), inanition (11.27%), pneumonia (4.75%), lesion obscured  (3.8%), hepatitis  (2.71%), egg bound (1.90%), blindness (1.76%) stampede  (1.49%) and cannibalism (1.22%).
Haematolohy of Ducks: The normal values of different parameters of ducks of three different breeds have been estimated. The estimated values of Hb in desi, Khaki and White Pekin were 10.05, 9.29,10.50; PCV 37.22, 34.20, 37.00; RBC 4.95,6.98,4.88; WBC12711.40, 13349.00, 16956.50; ESR (1hr) 4.14, 4.15, 2.18; ESR (2hr) 8.31, 7.57, 4.81 which revealed that there was not much variation in Hb, PCV, RBC but WBC, ESR, and bleeding time varied in these breeds of ducks. Differential count of lymphocyte, neutrophil showed variation among these breeds of ducks. However there was not much variation in other parameters.
Isolation and Identification of Bacteria: A total of 15 samples of fecal and internal organs like kidney, liver was screened. Proteus mirabilis, Salmonella pullorum  and E. coli  were detected by microscopical, cultural, biochemical   and molecular characterization (sequencing). 
Antibiogram of Isolates of Proteus  Mirabilis  : Proteus  mirabilis was highly sensitive to ciprofloxacin, ofloxacin, enrofloxacin, medium sensitive to chloramphenicol, kanamycin and streptomycin but was resistant to cloxacillin and doxycillin. Pathogenicity test revealed 12.33%
Seroprevalence of Duck Salmonellosis:  A total of 188 sera  samples  of duck were screened by slide agglutination test against Salmonella antigen ( Salmonella pullorum) out of which 12 samples(6.4%) were found  positive.

• The regional centre has been maintaining, multiplying and supplying germplasm of egg and meat type ducks in the form of hatching eggs, ducklings and growers as well as CARI Debendra chicks to beneficiaries in the region.
• Intensive rearing of ducks with artificial channel in run-space appeared to be an ideal management practice.
• CARI model of backyard chicken and duck farming enhanced household income and nutritional security to target beneficiaries.
• Integration of ducks with rice and fish yielded better economic return by improving water productivity.
