A high positive correlation was observed between total VFA production and ADF (r = 0.85; p < 0.001), NFC/NDF (r = 0.78; p = 0.001), NFC (r = 0.77; p = 0.001), OM (r = 0.75; p = 0.001), DM (r = 0.74; p = 0.002) and NDF (r = 0.74; p = 0.002), but there was only a moderate positive correlation with EE (r = 0.68; p = 0.005) and CP (r = 0.57; p = 0.026). This evidence concerns the gene CP and ocular melanoma.
