**5. Conclusions**

The dietary supplementation with CrPic + creeping wood sorrel determined an increase of crude protein concentration in breast meat, and CrPic + vitamin C and CrPic + creeping wood sorrel reduced the concentration of crude fat compared to those fed the C diet. Dietary supplementation with combinations of CrPic with vitamin C, Zn, and creeping wood sorrel improved the breast meat color, increasing the redness parameter and decreasing the luminosity parameter. Conversely, dietary supplementation with combinations of CrPic with vitamin C and creeping wood sorrel had a beneficial effect on textural parameters of chicken breast meat, increasing the tenderness. Furthermore, there was a clear relationship among proximate composition, color, and texture attributes of chicken meat. Taken together, this study revealed that a dietary combination of CrPic with vitamin C, Zn, creeping wood sorrel, respectively, as sources of antioxidants could attenuate the negative effects of heat stress on nutritional quality and texture without affecting the sensorial parameters of chicken meat.
