Abstract

The purpose followed in the present study was to identify the daily changes in body weight of broiler chicks employing image processing and MULTI-REGRESSION ANALYSIS. A number of, thirty 1-day-old broiler chicks were reared under standard rearing conditions and following the acquiring of their images, they were individually weighted. Out of 2490 digital images, six features (perimeter, area convex, major axis, minor axis, eccentricity) were picked up. Linear equations between body weight and the features indicated that R2 values for these features (except for eccentricity) for the individual birds exceeded 0.9. Furthermore, stepwise selection process was utilized to develop multi-regression model and to remove non-significant factors from the regression equation. According to the developed equation, area, perimeter, area convex, major axis, minor axis, interaction between area and major axis, as well as convex area, perimeter, major and minor axis were capable of predicting weight with R2=0.945 within the confidence level of %5. This shows that the digital image processing and MULTI-REGRESSION ANALYSIS could promisingly predict the weight of live chickens.
