Investigation of udder health and milk quality parameters of dairy farms in Northern Cyprus. Part II: Milk quality
Abstract
The purpose of this study was to determine milk quality status of dairy farms in Northern Cyprus. For this purpose, total bacteria and coliform counts in milk samples taken from all 138 dairy farms were counted, and samples were evaluated in terms of dry matter, fat, total protein, casein, lactose, free fatty acids, fat-free dry matter, acidity-SH, density, freezing point, citric acid and antibiotic residues, once a month during a year. It was determined that annual median values of 71% of the dairy farms, and the total bacteria count (TBC) median value of 47% of the samples was 100.000 cfu/ml; and that the annual median value was 227.738 cfu/ml. Coliform count was >100 cfu/ml in 71.5% of the samples. Antibiotic residues were detected in 2.6% of the samples. Milk composition analysis showed that dry matter, fat, total protein, casein, lactose, free fatty acids, fat-free dry matter, acidity-SH, density, freezing point, citric acid rates were 12.03%; 3.30%; 3.49%; 2.62%; 4.56%; 1.13%; 8.75%; 6.56 SH; 1.031,50 g; -0.542˚H and 0.131%, respectively. In conclusion, results of the study showed that 1) annual average of TBC was high, 2) Coliform count was high in every season (especially summer), 3) Milk composition had seasonal changes

Kuzey Kıbrıs’taki sütçü işletmelerde meme sağlığı ve süt kalitesi parametrelerinin araştırılması.Bölüm II: Süt kalitesi
Abstract
Bu çalışmanın amacı Kuzey Kıbrıs’taki sütçü inek işletmelerinde süt kalitesini araştırmaktı. Bu amaçla 138 işletmeye ait sürü tank sütünden bir yıl boyunca, ayda bir kez, toplam bakteri sayımı, koliform sayımı yapıldı ve örnekler kuru madde, yağ, toplam protein, kazein, laktoz, serbest yağ asitleri, yağsız kuru madde, asitlik-SH, yoğunluk, donma noktası, sitrik asit ve antibiyotik kalıntısı yönünden değerlendirildi. Yıl boyunca işletmelerin %71’inin, örneklerin ise %47’sinin toplam bakteri sayısı (TBS) medyan değerinin >100.000 cfu/ml olduğu, yıllık ortalama TBS medyan değerinin 227.738 cfu/ml olduğu saptandı. Koliform sayısı örneklerin %28.5’inde ≤100 cfu/ml; %71.5’inde ise >100 cfu/ml idi. Örneklerin %2.6’sında antibiyotik kalıntısı saptandı. Sütün bileşimi incelendiğinde kuru madde, yağ, toplam protein, kazein, laktoz, serbest yağ asitleri, yağsız kuru madde, asitlik- SH, yoğunluk, donma noktası ve sitrik asit oranı sırasıyla %12.03; %3.30; %3.49; %2.62; %4.56; %1.13; %8.75; 6.56 SH; 1 031,50 gr; -0.542 ̊H ve % 0.131 olarak tespit edildi. Sonuç olarak, çalışma sonuçları 1) Yıllık toplam bakteri sayısının yüksek olduğunu, 2) Koliform sayısının her mevsimde (özellikle yaz) yüksek olduğunu, 3) Süt bileşenlerinin mevsimsel olarak değiştiğini göstermiştir
