This study was conducted to evaluate the effect of subcutaneous administration of synthetic eugenol (EG) for disbudding of goat kids, as a new chemical method. Thirty apparently healthy Raieni (Cashmere) goat kids (five-day-old) were divided randomly into six groups (n = 5). In the pathology (P) groups (P3, P8 and P60 according to the sample collection day after injection) an amount of 0.10 mL of EG was subcutaneously administrated in both horn buds. In the disbudding 1 and 2 (DB1, DB2) groups, 0.10 mL of EG, and in the control (C) group 0.10 mL normal saline was subcutaneously injected in the right horn buds, respectively. Eugenol injection in DB2 group was done in twelve-day-old goat kids. The left horn buds of DB1, DB2 and C groups were considered as control of horn outgrowing. The horn buds, kidneys, liver, lung, brain and heart, tissue specimens were collected from P3 and P8 groups, and bud skin samples were collected from P60 group. The results showed that the EG was able to stop the horn growth in the first week of goat life. There was no significant difference between left and right horn size in the C group. Histopathological study revealed complete necrosis of bud tissue in dermal and epidermal layers, in P3 animals. Healing and re-epithelialization were seen in the samples taken from P8 group. Subcutaneous injection of the synthetic EG can be considered as a new method for goat kids disbudding.

This study was performed to evaluate the efficacy of injection of essential oil of Eugenia caryophyllata in the kid horn buds, as a new chemical technique for disbudding. Five-day-old healthy goat kids from both sexes (n = 16) were divided randomly into 4 equal groups. In groups 1, 2 and 3, 0.2 mL of clove essence and in group 4 (control) 0.2 mL of normal saline was injected into the left horn bud of goat kids. Right horn bud in all kids was considered to ensure that they are horned. During the study, the rate of horn growth were evaluated in determined time intervals between groups 1 and 4. Tissue samples were taken from right and left horn bud in groups 2 and 3, at five and ten days after clove essence injection, for microscopic study. The results of the study showed that the clove essence stopped horn growth, whereas there was no significant difference in horn growth rate between left and right horns after injection of normal saline, in group 4. Histopathological study showed that injection of clove essence caused complete necrosis of epidermis and underlying dermis with collagenolysis in horn bud tissues, 5 days after injection and then progress in healing process was observed after 10 days. According to the results of this study, it can be concluded that the injection of clove essence is an effective method to stop horn growth without any undesirable effects on clinical parameters in goat kids.
