dc.descriptionThe aim of the current study was to evaluate the effect of feeding Pelibuey sheep on diet supplemented with different doses of organic selenium (Se)-enriched yeast on carcasses microbiological contamination and meat physical characteristics. The experiment was conducted during the finishing stage of 18 female sheep and lasted for 60 days. In a complete randomized design, sheep were distributed to one of three treatments: the control without Se-yeast (T1), the control supplemented with Se-yeast at 0.35 mg Se/kg DM (T2), and control supplemented with Se-yeast at 0.60 mg Se/kg DM (T3). The yeast product used was Selyeast 3000TM yeast (LFA Lesaffre, Toluca, Mexico) with a Se concentration of 3000 ppm (mg/kg). Lambs were slaughtered at the end of the experiment at an average weight of 39.5±4.41 kg and samples were taken for microbiological analysis. There were no differences between treatments (P>0.05) and the aerobic plate counts for T1, T2 and T3 had indexes of 0.10, 0.08 and 0.08 log10 CFU/cm2 , respectively. Total coliform counts obtained were 0.13, 0.10 and 0.09 log10 CFU/cm2 for T1, T2 and T3, respectively, and the faecal coliform counts were 0.09 log10 CFU/cm2 for T1, 0.06 log10 CFU/cm2 for T2 and 0.07 log10 CFU/cm2 for T3. No significant effects (P>0.05) were observed for carcasses physical characteristics of microbial growth, initial and ultimate pH and temperature, colour values and water holding capacity. It can therefore be concluded that organic Se-enriched yeast did not affect carcasses bacterial proliferation or meat physical characteristics.-
