JARAMILLO-LOPEZ, Esaúl; PERAZA-MERCADO, Gwendolyne  e  ITZA-ORTIZ, Mateo. Sampling time and age at sacrifice over pH and meat color in hair sheep. Abanico vet [online]. 2020, vol.10, e503.  Epub 02-Mar-2021. ISSN 2448-6132.  https://doi.org/10.21929/abavet2020.19.

The objective of the present work was to evaluate the age at slaughter, carcass and muscle sampling time on the pH and meat color in lambs and sheep. The 25 sheep, 14 females and 11 males, weighing 41.06 ± 0.064 kg and 28.244 ± 2.435, respectively, were used. The age of the females was 2.32 years, and the males younger than 1 year, of undefined hair phenotypes. They sacrificed themselves by the disgorging method. After evisceration, the first pH reading was taken, as well as the color of the meat, then a sample of the Femoral muscle was taken, 24 h later, the second pH and color reading was taken in this muscle. The data obtained was analyzed with a completely randomized block design. The sampling time affected the pH (P <0.01) at zero time was 6,081 ± 0.057 vs 5,264 ± 0.017. For color there was no effect (P> 0.05) of age for, L*, a* and b*. However, the sampling time affected the L * and b * values (P <0.01). Age did not affect the pH and color of the meat, however, the sampling time affected both variables.
