Abstract

This study aimed to determine the distribution of pulsed wave Doppler ultrasonographic features of milk veins in lactating cows corresponding to udder health and the results of California Mastitis Test (CMT). Clinically healthy Simmental cows aged 3-5 years within the first 12 weeks of postpartum period were used for the study. End Diastolic Velocities (EDV), Systolic Peak Velocity (SPV), and Time-Averaged Maximum Velocity (TAMV) were the measured Doppler features of the milk veins. Numerical scales for Pulsatile Index (PI) and Resistant Index (RI) were devised in accordance with blood flow parameters. The animals were allocated to two groups according to CMT results as CMT positive (n=21) and CMT negative (n=5). No differences were found between the group regarding to PI, RI, EDV, or SPV (p>0.05). However, TAMV was found to be lower in CMT-positive animals (7.52 ± 0.85 cm/sec) compared to CMT-negative (13.90 ± 3.56 cm/sec) animals (p=0.021)

Özet

Bu araştırmada laktasyondaki ineklerde süt veninin pulsed wave doppler ultrasonografi özelliklerinin meme sağlığı ve California Mastitis Test (CMT) sonuçlarına göre dağılımı ve bu dağılıma etki eden faktörlerin belirlenmesi amaçlandı. Çalışmada klinik açıdan sağlıklı, Simmental ırkı, 3-5 yaşlı ve postpartum 12 hafta içinde olan inekler kullanıldı. Süt veninin doppler özellikleri olarak End Diastolic Velocities (EDV, Diyastol Sonu Kan Akım Hızı), Systolic Peak Velocity (SPV, En Yüksek Sistolik Kan Akım Hızı) ve Time-Averaged Maximum Velocity (TAMV, Zaman Ortalamalı Maksimum Kan Akım Hızı) ölçüldü. Kan akış parametrelerine bağlı kalarak Pulsatil İndeks (PI) ve Rezistans İndeks (RI) skalası çıkarılarak numerik bir ölçeklendirme yapıldı. Hayvanlar CMT sonuçlarına göre CMT pozitif (n=21) ve CMT negatif (n=5) olmak üzere ikiye ayrıldı. Buna göre PI, RI, EDV ve SPV açısından gruplar arasında fark bulunmadı (p>0.05). Ancak TAMV CMT pozitif (7,52 ±0,85 cm/s) hayvanlarda CMT negatif (13,90 ±3,56cm/s) hayvanlara nazaran daha düşük bulundu (p=0.021)
