In this study, milk samples were taken from Saanen goats. Then, they were tested in terms of somatic cell count (SCC), electrical conductivity (EI), total aerobic mesophilic bacteria (TAMB) count, and some physico-chemical parameters. The results were evaluated according to three different criteria and their usability in the preliminary diagnosis of and subclinical mastitis were aimed to demonstrate. In the study, milk samples were taken from a total of 313 Saanen goats that milked by hand 190 (60.7%) and 123 (39.3%) machine. Then, milk samples were analyzed in terms of SCC, dry matter, fat, protein, lactose, EI, pH and TAMB count. It was observed that milk samples gave more consistent results with the criteria of the European Union Authority. Thus, a statistical difference was found between milk samples below and above the European Union Authority SCC threshold value in terms of pH, protein, lactose and TAMB count (p<0.05). According to EC Authority; in milk samples with SCC below the threshold value; pH, protein and lactose ratio and TAMB count were 6.72%, 4.47%, 4.60% and 3.92 cfu/mL; above the threshold value; 6.76, 3.46%, 4.46%, and 4.98 cfu/mL, arespectively. It was observed that milk samples gave more consistent results with the criteria of the European Union Authority in the diagnosis of subclinical mastitis.

Bu çalışmada, Saanen ırkı keçilerden alınan süt örnekleri somatik hücre sayısı (SHS), elektriksel iletkenlik (Eİ), toplam aerobik mezofilik bakteri (TAMB) sayısı ve bazı fiziko-kimyasal parametreler bakımından test edilerek, sonuçların üç farklı SHS eşik değerine göre değerlendirilmesi ve subklinik mastitislerin tansında kullanılabilirliklerinin araştırılması amaçlandı. Çalışmada, 190 (%60,7) adeti elle, 123 (%39,3) adeti ise makineyle sağım olmak üzere toplam 313 baş keçiden alınan süt örneği kullanıldı. Süt örnekleri SHS, kuru madde, yağ, protein, laktoz, Eİ, pH ve TAMB sayısı yönünden incelendi. Böylece, Avrupa Birliği Otoritesi SHS eşik değerinin altında ve üstünde olan süt örnekleri arasında pH, protein, laktoz ve TAMB sayısı bakımından istatistiksel farklılık saptandı (p<0,05). Avrupa Birliği Otoritesi eşik değerinin altında SHS değerine sahip süt örneklerinde pH, protein ve laktoz oranı ile TAMB sayısı sırasıyla, 6,72, %4,47, %4,60 ve 3,92 kob/ml; eşik değerin üstünde SHS değerine sahip süt örneklerinde ise 6,76, %3,46, %4,46 ve 4,98 kob/ml olarak belirlendi. Süt örneklerinin subklinik mastitis tanısında Avrupa Birliği Otoritesi kriteriyle daha uyumlu sonuçlar verdiği görüldü.
