Abstract

The objective of the present study was to investigate the effect of mango peel meal supplementation in broilers on the quality and shelf life of their meat. Fifteen male COBB 500 chickens, 56 days old, were used. Randomly distributed in treatments T1, T2 and T3, not supplemented and supplemented with 1% and 2% mango peel flour (HCM), respectively. Five thigh samples were taken at random for each treatment, which were kept in refrigeration at temperatures between 4° and 5° and were transferred to the laboratory for subsequent analysis at 24 and 48 hours at the Veterinary Faculty of the Higher Polytechnic School Agropecuaria de Manabí (ESPAM) located in the city of Calceta. Quality parameters such as pH and humidity were analyzed, the microbiological parameters studied were Aerobic mesophilesand Staphylococcus aureus. These results were analyzed using the Shapiro Wilks statistical analysis (modified), to verify their normality. A lower bacterial growth was obtained with a number of microorganisms per gram of sample of 1 for Staphylococcus aureus in T1R2 and in T2R1 and T2R2 for Aerobic mesophiles, corresponding to 24 hours, giving acceptable results for them, but no statistically determined a positive effect between the addition of mango peel flour and the inhibition of bacterial growth.The shelf life of chicken meat was estimated at 24 hours and there was no more microbial growth at a higher concentration of mango peel flour. The shelf life of chicken meat was estimated at 24 hours and higher microbial growth was observed at higher concentrations of mango peel flour. Regarding the pH values, the decrease at slaughter was observed in T1 (5.4), at 24 hours in T3 (5) and at 48 hours in T1 (4.6). On the other hand, the humidity values correspond to T1 (73.70%), T2 (74.12%) and T3 (78.16%). It ends by concluding that the quality parameters for pH and humidity are acceptable, while the microbiological parameters are acceptable only in the repetitions of T1R2 for Staphylococcus aureus and T2R1 and T2R2 for Aerobic mesophiles at 24 hours. without having a positive effect with the additive and bacterial growth.
