The present work was undertaken to study the efficacy of low level laser therapy (LLLT) on healing of clinical open wounds in 16 calves. The calves were divided randomly into 4 groups. In control group-I antiseptic dressing was done till complete healing along with parenteral antibiotic for 7 days and analgesic for 3 days. The animals of groups II and III received the same treatment as in group I, in addition to low level laser therapy (LLLT) of 10Hz; 4 min; 2.4 J and 30 Hz; 4 min; 2.4 J respectively, whereas calves of group IV were treated with LLLT of 30 Hz; 4 min; 2.4 J laser along with normal saline dressing. In groups II, III and IV treatment with laser therapy was carried out continuously for five days. The rate of wound healing was assessed grossly on days 0, 3, 7, 10 and 14 posttreatment. Lesser inflammation and exudation with clinically no scab during healing was observed in the laser treated wounds of groups II, III and IV as compared to group I calves wounds. Maximum decrease in the size of the wound was observed in group II, followed by group III. It was concluded that low level laser therapy may improve healing of open wounds.
