Abstract

The aim of this study was to investigate the relationship between ultrasonographic (USG) measurements of teat canal and mastitis in cows. For this purpose, the length and diameter of teat canal were USG measured at fifty teats belonging to fifteen cows aged three and five, between two and sixth months of lactation. According to the results of California Mastitis Test (CMT), the teats were divided into two groups as positive and negative. Somatic cell count (SCC) was determined in milk samples taken from teat. Consequently, statistical analysis of all data obtained, length and diameter of teat canal were compared in CMT negative and CMT positive animals. There was no statistically significant difference between the groups for both parameters. Additively, there was a positive correlation (0.60) between the length and diameter of teat canal in the CMT positive group, and there were negative correlations between the teat canal length, milk density and mineral level (respectively, -0.46, and -0.45). Again, there was a negative correlation between the diameter of the teat canal and SCC (-0.48). In the comparison of milk components and some chemical properties between the CMT negative and CMT positive groups, statistically significant differences were found for other properties except fat (%) and mineral (%) values. In conclusion; It was concluded that there was no significant correlation between the length, diameter of teat canal and mastitis in cows, but it could be related with the parameters of milk composition and some chemical properties.

Abstract

Bu çalışmanın amacı ineklerde meme başı kanalının ultrasonografik (USG) ölçümlerinin mastitis ile ilişkisini araştırmaktı. Bu amaçla, üç ve beş yaş aralığında, laktasyonun iki ile altıncı ayları arasında olan 15 baş ineğe ait elli meme başında, meme başı kanalının uzunluğu ve çapı USG olarak ölçüldü. İneklere ait meme başları California Mastitis Test (CMT) sonuçlarına göre pozitif ve negatif olarak iki gruba ayrıldı. Daha sonra meme başlarından alınan süt numunelerinde somatik hücre sayısı (SHS) belirlendi ve süt kompozisyonuna ait analizler yapıldı. Elde edilen verilerin istatistiki analizleri sonucunda, CMT negatif ve CMT pozitif hayvanlarda meme başı kanalının uzunluğu ve çapı karşılaştırıldı. Gruplar arasında her iki parametre için de istatistiki olarak önemli bir fark bulunamadı. Ayrıca, CMT pozitif grupta meme başı kanalının uzunluğu ile çapı arasında pozitif korelasyon (0.60) olduğu, meme başı kanalının uzunluğu ile sütün dansitesi ve mineral düzeyi arasında ise negatif korelasyonlar olduğu (sırasıyla -0.46 ve -0.45) tespit edildi. Yine, meme başı kanalının çapı ile SHS arasında negatif korelasyon olduğu (-0.48) belirlendi. CMT negatif ve CMT pozitif gruplar arasında süt komponentleri ve bazı kimyasal özelliklerin karşılaştırılmasında ise yağ (%) ve mineral (%) değerleri hariç diğer özellikler için istatistiki olarak önemli farklılıklar bulundu. Sonuç olarak; ineklerde meme başı kanalının uzunluğu ve çapı ile mastitis arasında önemli düzeyde bir ilişkinin bulunmadığı, ancak sütün komposizyonu ve bazı kimyasal özelliklerine ait parametreler bakımından ise ilişkili olabileceği kanaatine varıldı.
