A Study about determining the changes in the structural characteristics of the digital cushion in heifer and multipar dairy cows: a preliminary report

Süt ineklerinde boynuz tırnak lezyonları önemli bir problemdir ve ciddi ekonomik kayıplara yol açar. Bunların oluşumunda ökçe yastığının yapısındaki değişikliklerin etkili olduğu düşünülür. Bu çalışmada; düve ve süt ineklerinde ökçe yastığının yapısal özelliklerindeki değişikliklerinin belirlenmesi amaçlanmıştır. Ökçe yastığının yapısındaki değişiklikler ultrasonografik ve gaz kromatografi yöntemi ile belirlendi. Ökçe yastığının kalınlığı ultrasonografik olarak ölçülebilir. Düvelerin ökçe yastığının yağ oranı sığırlardan daha düşük olup, doymuş yağ asitleri oranı daha yüksektir. Oluşan değişikliklerin tırnak içi travmatik etkiyi artırarak taban ülseri ve beyaz çizgi hastalığının oluşumunda etkili olabileceği söylenebilir.

Düve ve süt ineklerinde ökçe yastığının yapısal özelliklerindeki değişikliklerin belirlenmesi: ön çalışma raporu

Claw horn lesions are crucial problems for dairy cows and causes serious financial losses. The changes in the structure ofdigital cushion are considered to be the trigger for such lesions. The purpose of this study is to determine these changes inheifer and multipar dairy cows. The structural changes in the digital cushion were determined by ultrasonography and gaschromatography. As a result, it can be mentioned that thickness of the digital cushion can be measured by ultrasonographyand, also digital cushions of heifers have a lower percentage of fat than cows have and a higher rate of saturated fatty acidin their digital cushion. It can be asserted that these changes of digital cushion increase the traumatic effects inside the claw which may cause sole ulcer and white line disease.
