- Abstract
This study was undertaken to evaluate the use of photobiomodulation and photodynamic therapy as an auxiliary method for umbilical healing in calves, aiming at preventing omphalitis. Thirty newborn cattle that underwent treatment for umbilical lesion were evaluated. The animals were divided into three treatment groups, as follows: G1 - conventional treatment; G2 - conventional treatment + laser irradiation; and G3 - conventional treatment + photosensitizer and laser irradiation. Applications were performed only once and clinical evaluation was carried out throughout the experimental period until complete healing. The obtained data were analyzed using the Scott-Knott Test for mean comparison. The G2 animals performed better than G1 since D3, with complete healing by D15, whereas G3 showed better healing effectiveness from D3, compared with G1, and stood out relative to G2 at D12, when complete healing occurred. The G1 calves were healed at D21. As regards healing speed, after treatment, G3 had a 1.12 cm reduction in wound size when measured at D3, whereas G2 animals had it reduced by 0.89 cm and G1 by 0.5 cm, with statistical differences between these values (P<0.05). This study allows us to conclude that photobiomodulation and photodynamic therapy had positive effects in accelerating umbilical healing in calves, when compared with the control group. Between the treatments, aPDT showed better results than photobiomodulation, as it advanced total healing by three days.
