摘要: The effectiveness of clove oil and cautery disbudding on horn growth was evaluated in goat kids. study used 243 Saanen doe kids (4±1 days old; mean±SD) two farms that were disbudded with either (i) injection (CLOVE), (ii) a iron bud removed (BUDOFF), or (iii) left intact (BUDON). Each kid received different treatment per bud, which balanced between buds (left/right) randomly allocated. A trained observer monitored following for 3 months recording either: N: no growth, H: normal horn, S: abnormal (scur), SC: soft, fibrous lump (scorn). After the final observation, assessed probability detecting success (no growth), scurs, horns (iv) scorns [with 95% CI]. BUDOFF (0.77 [0.63, 0.87]) higher than BUDON (0.20 [0.11, 0.34]) CLOVE (0.09 [0.04, 0.18]; P ≤ 0.05). Furthermore, (P scurs (0.72 0.80]) (0.25 [0.17, (0.30 [0.21, 0.39]; There difference > (0.21 [0.15, 0.29]) (0.02 [0.01, 0.06]; 0.05); not observed BUDOFF. BUDON, only led to scorns, 0.41 (0.25, 0.60). These results suggest more effective at preventing appears most method, methods tested, Future research should explore other alternatives may be both efficacious cause less pain.
