Yield evaluation of broiler carcasses from a poultry processing plant with automated processing conditions in the Colombian Eastern Plains

Resumen

Objective: To evaluate the yield of dry and hydrated broiler carcasses from two suppliers that manage technical poultry processing plants in the Colombian Eastern Plains, per department (Cundinamarca and Meta) and per sex (females and males).
Design/Methodology/Approach: A total of n=777 broilers were used for carcass yield analysis, n=398 and n=384 of which were provided by supplier A and supplier B, respectively, with an equal proportion of females and males. Inferential statistics (ANOVA test) and descriptive statistics were used to determine the behavior of the analyzed variables, with the aim of determining a significant difference between the variables.
Results: Supplier B recorded the highest yields: an 11.93% increase in carcass after pre-chiller and chiller. The plains area near the processing plant of Cumaral recorded better results: 2.79% higher than the live weights of the Cundinamarca area. In the comparison by sex, the males were dominant, since their live weights were 5.47% higher and the carcass weights were 6.67% higher than in females.
Findings/Conclusions: After the pre-chiller and chiller processes, the yield of the  poultry meat production chain at AVIMA S.A. was >10% (weight increase of the dry carcass). In conclusion, the optimal stimulation of bird pores and the cooling generate profits in weight.
