Abstract The objective of this study was to evaluate quality of meat from hair lambs fed different energeticsources in the finishing phase. Twenty-eight hair lambs with an initial body weight (BW) 20.8 ±3.01, were randomly assigned to one of four dietary treatments included with seven lambs pertreatment included an energy source included at 18% dry matter: S. spectabilis flour (SF), palm kernel (PK), corn bran (CB) and rice bran (RB) in a diet based in corn silage, ground corn, soybean meal formulated to 13% PC and 2.6 Mcal/Kg DM. The feeding was performed for 13 weeks. Animals were slaughtered after the feeding trial, and the carcasses were kept at 4°C for 24 hours under Colombian standard guidelines. 0 and 24 hours after slaughter from the Longissimus dorsi of the left half carcass between 12th and 13th ribs for color analysis (L*, a*, and b*) and pH. Thestatistical model included the effects of diet, time, and their interactions. There was no effect of treatment on pH and L* and b* indices (P > 0.05). Aging time increased b* values and reduces the pH values, L* values and a* values (P < 0.05). The a* values were higher in the time 0 and 24 for the RB treatment (P < 0.05). On the other hand, there is no effect of the interaction of treatment x time in the pH, L* an and b* values. In conclusion, meat quality from lambs fed different energetic sources at 18% of DM is not influenced by the diet.
