Evaluation o time transport effect on weight lost of broiler in two commercial lines

Abstract

The effect of the transport time on lost of live weight and carcass of broilers in two lines in four different farms was evaluated. 930 birds were taken to analyze the transport effect from the farm to the benefit plant over lines and sexes and its influence on mortality and economical lost. 96 trips with 163.724 broilers were analyzed to characterize the information of the variables time, line, sex, and weight, we also used descriptive statistical, correlation analysis and two regression models to determine the economic lost, and to establish the existence of differences in the reduction, we worked with one random design 4x2x2. Additionally and because of the different handling follow in each farm a random design was implemented 2x2. Difference in the lost weight among males and females was found., there were no significant differences for the carcass in the four farms, and into the ranch only were differences for sex. Males were more affected by the conditions, the quality and the transport time than the distance from the farm to the benefit plant.
