Sunulan çalışmada, Afyonkarahisar'da bulunan aile tipi işletmelerde subklinik mastitis insidensinin belirlenmesi ve subklinik mastitise neden olan risk faktörlerinin belirlenmesi amaçlandı. Laktasyondaki 202 ineğin 757 meme lobuna California Mastitis Testi yapıldı. İneklerin %74'ü ve meme loblarının %41'inde subklinik mastitis belirlendi. Sürüde 10 ve daha az hayvan bulunan ve laktasyonun son döneminde olan (>180 gün) ineklerin meme loblarında subklinik mastitis gözlenme oranının daha yüksek olduğu saptandı (p<0,05). İneklerde yaşın subklinik mastitisin görülme insidensini istatistiksel olarak önemli oranda arttırdığı (p<0,05) belirlenmesine rağmen ineklerin ırk farklılıklarının, sağım yöntemlerinin, sağım sonrası teat-dipping uygulamalarının ve meme lokalizasyonlarının bu insidensi etkilemediği tespit edildi. Sekiz yaşından daha büyük ineklerin meme loblarının 2-5 yaş grubundaki ineklerin meme loblarına göre yaklaşık 3,02 kat daha fazla enfeksiyon riskine sahip oldukları saptandı. Ayrıca sürü büyüklüğü 10 ve altında olan sürülerde 10’un üstünde olan sürülere göre enfeksiyon riskinin yaklaşık 1,75 kat daha yüksek olduğu tespit edildi. Sonuç olarak, Afyonkarahisar'daki aile tipi işletmelerde subklinik mastitis insidensinin yüksek olduğu ve bu oranı azaltmak için mastitis kontrol programlarının uygulanmasının gerektiği belirlenmiştir.
In the presented study, the aim was to identify the incidence of subclinical mastitis in family-type enterprises in Afyonkarahisar and identify the risk factors that cause subclinical mastitis. In 202 cows in the lactation, 757 breasts were tested for California Mastitis. In 74% of cows and 41% of breast lobs, subclinical mastitis was detected. It was found that cows with 10 or less animals and in the last period of lactation (>180 days) had a higher rate of observation of subclinical mastitis in the breast lobs (p<0,05). Despite the statistically significant increase in the incidence of subclinical mastitis in cows (p<0,05) the age has been determined, the variations of races, the methods of feed, the post feed-dipping applications and the breast localizations have not affected this incidence. It was found that cows older than eight years of age had approximately 3,02 times greater risk of infection than cows of the 2-5-year-old group. The risk of infection was approximately 1.75 times higher than the risk of infection was found in grapes with the size of the grapes 10 and below. As a result, it has been determined that the incidence of subclinical mastitis in family-type enterprises in Afyonkarahisar is high and that it is necessary to implement mastitis control programs to reduce this rate.
The aim of this study was to determine the incidence of subclinical mastitis and risk factors causing subclinical mastitis in smallholder dairy farms in Afyonkarahisar. California Mastitis Test was applied to 757 quarters belonging to 202 lactating cows. Seventy-four percent of the cows and 41% of the quarters were subclinically infected. Quarters from cows in smallholder dairy farms with 10 or fewer animals in the herd and quarters from cows in the later stage of lactation (>180 days in milk (DIM)) were more likely to have subclinical mastitis (p<0.05). Although the effect of age was statistically significant (p<0.05) on the incidence of subclinical mastitis, breed factor, milking method, teat-dipping after milking and localization of mammary quarters were not statistically significant. It was found that the quarters in cows older than 8 years had a 3.02 times higher risk of infection than the quarters in cows in the 2-5 age group. The risk of infection in flocks with a herd size of 10 or less was found to be about 1.75 times higher than flocks with a herd size greater than 10. In conclusion, it was determined that the incidence of subclinical mastitis was high in smallholder dairy farms in Afyonkarahisar and mastitis control programs should be applied to decrease this rate.
