| dc.description.abstract | A study was conducted to evaluate the production performance of 275 chicks of two ecotype viz., comb and crown which were obtained in six hatches at Instructional Poultry Farm of G.B.P.U.A. & T., Pantnagar. Body weight was recorded at four week interval from day old to 24th weeks of age. Among comb and crown ecotypes of Uttara fowl, comb male ecotypes showed maximum body weight gain (1780.18±34.69 g), followed by crown male (1699.43±33.49 g), while it was (1484.22±19.22 g) in crown female and minimum in comb female ecotypes (1389.12±18.85 g) among two ecotypes of Uttara fowl. The crown ecotype under study obtained early age at first egg (161.5±3.05 days), with body weight (1422.50±31.21g), whereas comb ecotypes attained age at first egg at later (171.05±2.18 days) with body weight (1350.40±35.35 g). The average egg production up to 72nd week of age in crown ecotypes of Uttara fowl (177.35±6.34 eggs) was found higher than the comb ecotypes of Uttara fowl (153.54±5.64 eggs). The average egg weight were recorded at first egg, 24th, 28th, 32nd, 36th, 40th, and 44th week of age in comb ecotypes were 34.85±0.47, 39.25±0.79, 42.80±0.40, 46.80±0.73, 50.50±0.59, 52.80±0.51 and 53.40±0.21 g, respectively. While corresponding values in crown ecotypes of Uttara fowl were reported as 37.05±0.93, 41.30±1.08, 44.80±0.79, 47.80±0.63, 51.40±0.68, 53.20±0.92 and 54.40±0.84 g, respectively. The mean values of egg weight (g), shell weight (g), shape index, haugh unit, albumen index, yolk index, yolk weight (g), shell thickness (mm), at 32nd weeks of age in comb and crown ecotypes of Uttarafowl were 46.80±0.73, 5.88±0.067, 73.64±0.19, 74.48±0.42, 0.080±0.002, 0.42±0.008, 13.20±0.32 and 0.38±0.028, respectively and 47.80±0.63, 6.16±0.10, 74.31±0.41, 75.20±0.55, 0.082±0.003, 0.44±0.01, 14.80±0.32 and 0.43±0.032, respectively. Thus on the basis of findings reported under study, it may be concluded that Uttara fowl has great scope in rural backyard poultry in Uttarakhand. Uttara fowl has potential to develop as dual purpose bird which can be achieved through intensive selection and breeding program. | en_US |
