Abstract:

Present study predicted 6th week body weight of Caribro-Dhanraja broilers (n=75) with different plumage colour through backward elimination regression from 2nd week growth traits (weight, weight gain, chick length, weight: length2, shank length, toe length, breast length, breast girth, thigh length and wing length). Day old chicks were grouped into yellow, black and stripped colour groups based on plumage colour (25 chicks in each group) and traits were measured biweekly upto 6th week. Plumage colour significantly influenced shank, toe and thigh length, and breast girth at 2nd week; whereas, wing length at 4th week (Pï‚£0.05). In yellow plumage group, weight, daily gain, weight: length2, shank, breast and thigh length at 2nd week were positively associated with 6th week body weight (Pï‚£0.05). In black plumage group, weight, daily gain and weight: length2 of 2nd week were positively association with 6th week body weight, but thigh length was negatively associated (Pï‚£0.05). Weight, daily gain and weight: length2 at 2nd week were positively associated with 6th week body weight in stripped plumage group (Pï‚£0.05). Backward elimination regression model for prediction of 6th week body weight from 2nd week variables revealed higher R2 value (59.6%) in black plumage (predictor variables were weight, breast girth and thigh length). However, R2 value was 36% for stripped colour (predictor variables were weight and breast girth), 25.3% for yellow plumage (predictor variable was wing length) and 41% for pooled data (predictor variables were growth and breast girth). The results indicated lower accuracy for prediction of 6th week body weight based on variables from 2nd week.
