Abstract:
A study of white leghorn strain maintained at the poultry farm of department of Animal Genetics and Breeding, LUVAS, Hisar, was conducted to investigate the possibility of prediction of the 40 week egg production from part egg production traits. The part egg production traits included for the prediction of 40 wk egg production were egg production from 25 to 28 week of age (EPP1), 29 to 32 week of age (EPP2) and 33 to 36 week of age (EPP3). Multiple regressions analysis was used to predict the 40 week egg production from part egg production. Equation containingEPP1 and EPP2 explained 45% of variation in 40 wk egg production. When all the three traits EPP1, EPP2 and EPP3 were taken together in the prediction equation then equation explained 63% of variation in 40 wk egg production. So it may be concluded that the equation havingEPP1, EPP2 and EPP3 is best for production of 40 wk egg production.
