Evaluación de factores que afectan la calidad de las carcasas en pollos de engorde durante el proceso de faenamiento.

Abstract

The objective of the study was to evaluate the factors that affect the quality of carcasses in broiler chickens during the slaughter process. We worked in a broiler slaughter plant in Guayaquil. The study was defined as a nonexperimental descriptive observational cross-sectional study with a sample of 300 chickens. As results, it was observed that the majority did not present injuries or alterations in the musculoskeletal system (72.00 %); no dead chickens upon landing. The presence of injuries in general was 28.00 %. The most common injuries were hematomas (26.33 %) followed by fractures (1.67 %) and all presented pododermatitis to different degrees. All the fractures were in the wing and were deep red in color; while the majority of bruises occurred in the wing (69.62 %) followed by the breast (20.25%) and were deep red and red in color with 49.37 % and 24.05 % respectively. No statistically significant relationship was observed (p-value: > 0.05) between the presence of injuries with the hours of travel or with the management carried out on the farms. Meanwhile, there was a relationship between the management carried out on the farms with the presence of fractures and the degree of pododermatitis. All fractures originated in the slaughter plant. The bruises originated on the farm (75.95 %) and in the slaughter plant (24.05 %). The general loss was 7.77 %, the majority in slaughter with 7.38 %.
