Prevalence of Subclinic Mastitis and its Impacts in Anatolian Buffaloes

Öz

The aim of this study was to calculate the prevalence and changes in milk due to subclinical mastitis in Ana-tolian buffaloes, and the financial losses caused by the disease. The material of the study consisted of milk samples obtained from 96 udder lobes belonging to a total of 24 female Anatolian buffaloes raised in Kayseri. Milk samples were collected from four farms in March 2021 and the infection status of the milk was evaluated by examining the Cali-fornia Mastitis Test (CMT) and somatic cell count (SHS). According to the results, 5 buffalo (20.8%) and 8 lobes (8.3%) were found to be infected and mean SHS value was found as 182500 cell/ml. The fat of infected animals milk de-creased by 27.4% (P<0.05) and the milk yield decreased by 12.6%, if the disease was not treated, it was calculated that a loss of 1140 TL (138 $) will occur in a lactation, and if treated, this loss can be reduced by 951.5 TL (115 $). In conclusion, it was revealed that the prevalence of subclinical mastitis in Anatolian buffaloes raised in Kayseri is high (20.08%), infection significantly reduces milk fat, especially in terms of quality, producers should educate in terms of diseases and pay more attention to hygiene, otherwise subclinical mastitis will cause significant losses and reduce their profitability.

Anadolu Mandalarında Subklinik Mastitis Prevalansı ve Hastalığın Etkileri

Öz

Bu çalışmanın amacı, Anadolu mandalarında subklinik mastitis prevalansının ve sütte meydana getirdiği değişiklik-lerin belirlenmesi ile hastalığın oluşturduğu finansal kayıpların hesaplanmasıdır. Araştırmanın materyalini Kayseri’de yetiştirilen toplam 24 baş dişi Anadolu mandasına ait 96 meme lobundan elde edilen süt örnekleri oluşturmuştur. Süt örnekleri Mart 2021’de dört işletmeden temin edilmiş olup, sütlerin enfeksiyon durumu Kaliforniya Mastitis Test (CMT) ve somatik hücre sayısı (SHS) incelenerek değerlendirilmiştir. Araştırma bulgularına göre, 5 manda (%20.8) ve 8 me-me lobunun (%8.3) enfekte olduğu ve ortalama SHS değerinin 182500 hücre/ml olduğu tespit edilmiştir. Enfekte hay-vanların süt yağının %27.4 oranında (P<0.05) ve süt veriminin %12.6 oranında azaldığı, hastalığın tedavi edilmemesi halinde bir laktasyonda 1140 TL (138 $) kayıp oluşacağı, tedavi edilmesi halinde ise bu kaybın 951.5 TL (115 $) azaltı-labileceği hesaplanmıştır. Sonuç olarak, Kayseri’de yetiştirilen Anadolu mandalarında subklinik mastitis prevalansının yüksek olduğu (%20.8), enfeksiyonun özellikle kalite açısından süt yağını önemli oranda azalttığı, üreticilerin hastalıklar konusunda eğitilmesi ve hijyene daha fazla dikkat etmesi gerektiği, aksi halde subklinik mastitisin işletmelerde önemli ekonomik kayıplara yol açarak karlılıklarını azalttığı ortaya çıkmıştır.
