. Bu çalışmada, 22 buzağıya %20'li.k kalsiyum klorit solüsyonunun boynuz düğmesi altına enjeksiyonuyla dehorning uygulandı. Iki-üç ml miktarındaki solüsyonun enjeksiyonu boynuz düğmesi altına merkezi olarak yapıldı. Enjeksiyondan 4-5 gün sonra kuru, yuvarlak bir nekrotik alan palpe edildi. Bu nekrotik dokunun atılması ve iyileşme 6-8 haftada tamamlandı. Hayvanlar boynuz üremesinin durumu ve bölgede oluşan değişimlerin gözlenmesi açısından asgari 6 ay izlendi. İki buzağıda uygulama yapılan bölgeden 1 hafta sonra alınan doku örneklerinin histolojik yoklamasında epidermisin tamamen yok olduğu, dermiş ve kas tabakası bölgelerinde kollagen ipliklerden zengin sıkı fıbröz bağ doku üremesinin oluştuğu gözlendi. Sonuç olarak, %20'lik kalsiyum klorit solüsyonuyla uygulanan kimyasal dehorning'in buzağıların boynuzsuzlaştırılması için güvenilir, ekonomik ve kolay uygulanabilir bir teknik olduğu belirlendi

Dehorning is an important aspect ofcow veterinary practice and it is usually performed on calves betvveen 1 yveek and 2 months of age. Iıı this study, Chemical dehorning was carried out on 22 calves bet\veen 1 week and 2 months of age using 20% solution of calcium chloride via subcutaneous injection. The injections of 2-3 ml of the solution were given under the çenter of horn bud. A circle of dry necrotic area was palpated 4-5 days after injection. Separation of the necrotic tissue and healing process completed in 6-8 weeks. The animals were observed for a minimum of 6 months for the condition of horn growth and changes occuring in the area. In the histological examiııation of the tissue samples taken 1 w e ek later from the area of intervention it was observed that the epidermis had disappeared compl.etely and a firm fibrous connective tissue proliferation rich in collagen fibrils occured in the area of dermiş and mııscle layers. Consequently, Chemical dehorning with a 20% solution of calcium chloride has been foıuıd as reliable, economic and simple technicpıe for disbudding of calves.
