Evaluation of effects of milking hygiene and management factor on clinical mastitis incidence in dairy cows

Bu çalışmanın amacı farklı sağım yönetimine ve hijyen şartlarına sahip altı adet sütçü inek işletmesinde klinik mastitis insidensi ve somatik hücre sayısını belirlemekti. Çalışmada 431 Holstein-Friesian inek kullanıldı. Sütçü inek işletmeleri sağım hijyeni ve yönetimine göre iyi; (Grup I, n=2), orta (Grup II, n=1) ve kötü (Grup III, n=3) olarak sınıflandırıldı. Çalışma bu 3 grup üzerinde yürütüldü. Klinik mastitisin tanısında meme loblarındaki patolojik değişiklikler ve sütteki normal olmayan değişiklikler esas alındı. Klinik mastitis oranı iyi, orta ve kötü koşullarda sırasıyla; %20.2; %28.3 ve %36.5 olarak belirlendi. Bireysel ve tank süt somatik hücre sayısı normal, orta ve yüksek olarak kategorize edildi. İyi sağım hijyeni ve yönetimine sahip işletmelerde meme loblarının %82’sinin düşük somatik hücre sayısına (

Sütçü ineklerde sağım hijyeni ve yönetiminin klinik mastitis insidensi üzerine etkisinin değerlendirilmesi

The aim of this study was to determine the prevalence of clinical mastitis and somatic cell count (SCC) in six dairy herdswhich had different milking management and hygiene conditions. Four - hundred thirty one Holstein - Friesian cows were usedin the study. The herds were classified to be good (Group 1, n=2), medium (Group 2, n=1) or bad (Group 3, n=3) accordingto milking management and hygiene. The study was carried out on these 3 groups. Diagnosis of clinical mastitis was basedon pathological symptoms in quarters and abnormal changes in milk. Rates of clinical cases were 20.2%, 28.3% and 36.5% forgood, medium and bad conditions. Individual (ISCC) and bulk tank (BTSCC) somatic cell count were categorized to be low,medium and high. Of the quarters, 82% had low ISCC (<200.000 cells mL-1) in herds with good milking hygiene. Average ISCCand BTSCC values were higher in bad conditions than others (P<0.05).
