Lesion size
There was a highly significant Treatment × Day interaction (P< 2×10–16) for lesion size (Figure 4), indicating different rates of healing across the three groups. Initially, there were no significant differences in mean wound sizes amongst the three groups (all P > 0.25). While mean wound size increases for Control cattle, they reduced for the two treatment groups, with those in the TS treatment reducing at a faster rate (differences were significant from Day 9, all P < 0.01). There was no significant effect of Age (P = 0.454), Breed (P = 0.225), nor Sex (P = 0.374) on lesion size.
