Ultrasonographic Evaluation of the Teat Canal in Dairy Cows

Öz

Ultrasonography is a noninvasive technique that can be used to examine the udder and teats in cattle. The aim of this study is to investigate the relationship between the length of the ductus papillaris (Dp), known as the teat canal, and some maternal factors such as race, parity, mastitis, pregnancy and milking method. The animal material of the study consisted of a total of 50 clinically healthy cows of different breeds (Holstein, Simmental, Montofon) and ages. Within this scope, data on breeds, parity, mastitis, pregnancy, and milking method were evaluated. All teats were tested by the same person who had experience with the ease or difficulty of hand milking. After a general clinical examination and cleaning of the udder, Dp lengths were measured and recorded using ultrasonography (5-7.5 MHz linear probe). As a result, the average Dp lengths in all animals were determined to be 9.80±2.08 mm (right) and 9.90±2.03 mm (left) in the front teats, and 10.22±1.91 mm (right) and 10.29±1.92 mm (left) in the rear teats. There was no statistically significant difference between Dp lengths at the teat ends (p>0.05). Furthermore, significant difference was not found between Dp and breed, parity, mastitis status, pregnancy and ease or difficulty of milking (p>0.05).

Süt İneklerinde Meme Başı Kanalının Ultrasonografik Değerlendirilmesi

Öz

Ultrasonografi sığırlarda meme ve meme başlarının incelenmesinde kullanılabilecek noninvazif bir tekniktir. Bu çalışmanın amacı meme başı kanalı olarak bilinen duktus papillaris (Dp) uzunluğunun ırk, parite, mastitis, gebelik ve sağım şekli gibi bazı maternal faktörlerle ilişkisini araştırmaktır. Çalışmanın hayvan materyalini farklı ırk (Holstein, Simmental, Montofon) ve yaşta, klinik olarak sağlıklı toplam 50 inek oluşturdu. Bu kapsamda ineklerde ırk, parite, mastitis, gebelik ve sağım şekli verileri ultrasonografik ölçümler eşliğinde değerlendirildi. Elle sağım ile tüm meme başlarında sağımın kolaylığı veya zorluğu tecrübesi olan aynı kişi tarafından test edildi. Memenin genel klinik muayenesi ve temizliği yapıldıktan sonra Dp uzunlukları ultrasonografi (5-7.5 MHz lineer prob) ile ölçülerek kaydedildi. Sonuç olarak, tüm hayvanlarda ortalama Dp uzunluklarının ön meme başlarında 9.80±2.08 mm (sağ) ve 9.90±2.03 mm (sol) ve arka meme başlarında 10.22±1.91 mm (sağ) ve 10.29±1.92 (sol) mm olduğunu tespit edildi. Meme başlarındaki Dp uzunluklarında istatistiksel anlamda bir fark bulunmadı (p>0.05). Ayrıca Dp ile ırk, parite, mastitis, gebelik ve sağımın kolaylığı veya zorluğu arasında anlamlı bir farklılık tespit edilmedi (p>0.05).
