Abstract :

An experiment was conducted at Kerala Veterinary and Animal Sciences University in order to assess the trends in the yield of cut–up parts in Kuttanad ducks over four generations of selection in Kuttanad ducks. Three generations (S1, S2 and S3) were produced from a base generation (S0) through individual selection based on body weight at eight weeks and pedigree eeding. The yield of cut–up parts of 10 ducks each of either sex selected at random were evaluated at eight, 10 and 12 weeks of age in four generations. Statistical analysis of the yield of cut–up parts between generations revealed that the percentage yield of east portion was significantly (p<0.05) higher in S3 generation at 8, 10 and 12 weeks of age. The findings suggest that as a result of selection appreciable progress could be achieved in the S3 generation with regard to the yield of cut–up parts
