Özel bir mezbahadan elde edilen 112 sığıra ait 448 ayağın tırnaklan, makroskopik ve histopatolojik olarak incelendi.

Değerlendirilen ayakların 110'u Holstayn, 1'i Simental, 1'i Yerli Kara ırkına ait idi. Bunlardan 89'u erkek, 23'ü dişiydi. Ayakların makroskopik incelemesi sonucunda 38 olguda taban-ökçe çürüğü, 22 olguda taban çürüğü, 29 olguda ökçe çürüğü, 30 olguda kronik-subklinik laminitis, 12 olguda beyaz çizgi ayrılması, 4 olguda interdigital panarisyurn, 6 olguda digital dermatitis, 18 olguda aşın tırnak uzaması saptanırken, 7 sığır ayağında lezyon belirlenemedi.

 Kronik-subklinik laminitis, ökçe ve taban çürüğü bulunan tırnakların kapsulalan çıkarıldı. Makroskopik olarak, kapsulada lezyon belirlenen bölgede hiperemi mevcuttu.

Taban ve ökçe çürüğü bulunan olguların histopatolojik incelemelerinde, korium dokusunun normal yapısını kaybettiği ve bu dokunun tüm katlarını kaplayan mononüklear yangı infiltrasyonu olduğu belirlendi. Keratinize taban dokusuna yakın bölgedeki korium dokusunda nekroz, çevresinde ödem ve bağdoku hiperplazisi gözlendi.

MACROSCOPİCAL AND HİSTOPATHOLOGİCAL EVALUATİON OF POSTMORTEM COW FEET

Summary

 Macroscopical and histopathological investigations with respect to foot diseases were performed in 448 feet belonging to 112 cattle obtained from a private slaughterhouse.

Of the feel which were selected for assessment 110 belonged to the Holsiein breed, 1 to the Simental breed and 1 to the yerli kara breed (a local breed). Of these. 89 were male and 23 were female. Macroscopical evaluation of the feet revealed the following diseases: sole and heel erosion in 38 cases, sole erosion in 22 cases, heel erosion in 29 cases, chronic and subclinic laminitis in 30 cases. Digital dermatitis was found in 6 feet, interdigital panaritium in 4, white line separation in 12, claw overgrowth in 18, and 8 cases had healthy claws.

The capsulae of claws with chronic laminitis and heel and sole erosions were removed. A higher degree of hyperaemia was observed in corium regions relating to areas with severe sole and heel erosions in the capsule.

In the histopathological evaluation of cases with sole and heel erosions and chronic laminitis, it was seen that the corium lost its normal structure and there was mononuclear inflammatory infiltration through all the layers of this tissue. Necrosis in the corium, as well as oedema and connective tissue hyperplasia, was observed in the region near the keratinised sole tissue.

Key Words: Macroscopic examination, postmortem examination, histopathologic examination, foot, cattle.
