Effects of copper levels on goat carcass traits and meat quality

The objective of the current study was to evaluate high levels of dietary copper (Cu) on goat carcass traits and meat quality. Thirty-six French Alpine goats (18.43 ± 2.35 kg) were randomly assigned to 6 treatments (basal diet with Cu levels at 0, 10, 20, 40, 80, and 160 ppm) with 6 replications ea...

description The objective of the current study was to evaluate high levels of dietary copper (Cu) on goat carcass traits and meat quality. Thirty-six French Alpine goats (18.43 ± 2.35 kg) were randomly assigned to 6 treatments (basal diet with Cu levels at 0, 10, 20, 40, 80, and 160 ppm) with 6 replications each. The experiment was carried out for 102 d. Plasma Cu and enzymes, and slaughter variables were not different (P > 0.05) between Cu levels. Cu in the goat diets was significant (P < 0.05) for meat lightness (L*) and yellowness (b*); L* values were higher (P <0.05) at 20 ppm and lower (P < 0.05) at 10 and 80 ppm; b* was highest (P < 0.05) for the 160 ppm level and lowest (P < 0.05) for 40 ppm. Meat adhesiveness presented differences (P < 0.05) between Cu levels; the 10 ppm group showed the highest value (P < 0.05) and 0 ppm the lowest value (P < 0.05). Meat juiciness for 10 ppm was higher (P < 0.05) than meat for the 80 ppm group. Linear regression demonstrated that b* and springiness were dependent (β1 ∕= 0; P ≤ 0.05) on Cu levels in the diet. In conclusion, high Cu levels are recommended in the goat diet to enhance meat quality without affecting slaughter variables.
