Evaluation of the effect of automatic and conventional machine milking on somatic cell and aerobic plate count
Öz
Milking style affects milk quality and udder health. In this study, the effect of milking system on the number of aerobic bacteria and somatic cell count in milk was investigated in cows milked using conventional machine milking and automatic milking systems. The study material consisted of milk samples collected from farms using conventional machine milking and automatic milking system. Log10 conversions of aerobic bacteria and somatic cell numbers in milk samples were made according to milking type, and Student T test was used for statistical comparison.
As a result of the study, the number of aerobic bacteria in milk samples obtained from conventional machine milking and automatic milking showed a statistically significant difference (p=0.002), but no significant difference was found in terms of somatic cell count (p=0.605). Accordingly, the number of aerobic bacteria (Log10) in milk samples was calculated higher in conventional machine milking (4.83) than automatic milking (4.28).

Otomatik/robotik ve geleneksel makineli sağımın somatik hücre ve aerobik kültür sayısı üzerine etkisinin değerlendirilmesi
Öz
Sağım şekli süt kalitesi ve meme sağlığını etkilemektedir. Yapılan bu çalışmada, geleneksel makineli sağım ile otomatik sağım sistemleri kullanılarak sağılan ineklerde sağım sisteminin sütteki aerobik bakteri sayısı ve somatik hücre sayısı üzerine etkisi araştırılmıştır. Çalışma materyalini makineli sağım ile otomatik sağım sistemi kullanan çiftliklerden toplanan süt örnekleri oluşturmuştur. Sağım tipine göre süt örneklerindeki aerobik bakteri ve somatik hücre sayılarının Log10 dönüşümleri yapılmış, istatistik karşılaştırmasında Student T test kullanılmıştır.
Çalışma sonucunda makineli sağım ile otomatik sağımından elde edilen süt örneklerinde aerobik bakteri sayısı istatistik olarak anlamlı farklılık göstermiş (p=0,002), somatik hücre sayısı bakımından anlamlı farklılık bulunmamıştır (p=0,605). Buna göre süt örneklerinde aerobik bakteri sayısı (log10) makineli sağımda (4,83) otomatik sağımdan (4,28) daha yüksek hesaplanmıştır.
