İç Anadolu Bölgesi Şartlarında Siyah Alaca ve Simental Irkı İneklerde Mastitis ve Metritis Görülme Oranları

Abstract

Bu çalışmada; Türkiye’nin İç Anadolu Bölgesinde yer alan özel bir işletmede yetiştirilen Siyah Alaca ve Simental ırkı sığırlarda metritis ve mastitis görülme oranları incelenmiştir. Hastalıkların görülme sıklığını etkileyen ırk, yaş ve yıl faktörlerinin değerlendirilmesi yapılmıştır. Çalışmanın materyalini 2013-2017 yıllarında işletmede bulunan 4164 baş Siyah Alaca ve 892 baş Simental dişi sığırlara ait veriler oluşturulmuştur. İşletmedeki dişi sığırlar yaş kategorilerine göre düve ve inek (2, 3, 4, 5, 6 ve üzeri) olarak sınıflandırılmıştır. Hastalık oranları hesaplanırken incelenen tarihler arasında ilgili yaşa ait toplam hayvan sayısı ile ilgili hastalığa en az bir kere yakalanan hayvan sayısı kullanılmıştır. Mastitisin yaşla birlikte arttığı; metritisin ise 3 yaş altı ve 6 yaş üstü ineklerde arttığı görülmüştür. Siyah Alaca ırkı sığır-ların Simentallere göre mastitis ve metritise yakalanma eğiliminin daha yüksek olduğu tespit edilmiştir.

Mastitis and Metritis Rate in Holstein and Simmental Cows under the Central Anatolia Conditions

Abstract

The study was evaluated to detect metritis and mastitis rates of dairy cows with different age groups and breeds in an intensive dairy farm located in the Central Anatolian Region of Turkey. The data from 4164 Holstein and 892 Simmental cows between 2013-2017 were allocated to different age groups such as heifers, cows (2, 3, 4, 5, 6+ years). The exposed groups with related risk age which the relative diseases were detected at least once during the risk period were contributed to the nominator while all population with the related risk age were contributed to the de-nominator when calculating proportions for morbidity rates in excel worksheets. The chi-square test was used to deter-mine statistical differences of the factors. Mastitis rate was found to be more widespread in older cows while mastits rate was found to be more common in those younger than 3 years of age and older than 6 years of age. Holstein cows tended to be more sensitive to the metritis and mastitis. With obtaining remarkable significant results, the multiparous cows were seen prone to higher morbidity rates.
