Sütçü sığır işletmeleri için postpartum (PP) dönem uterus enfeksiyonları ekonomik açıdan oldukça önemlidir. Ekonomik etki daha çok infertilite kaynaklıdır. İnfertilite sonucunda hayvanın kesime gönderilmesi, süt üretiminde azalma meydana gelmesi ve buna ek olarak da tedavi masrafları infertiliteyi dolayısıyla uterus enfeksiyonlarını önemli bir ekonomik sorun haline getirmektedir. Uterus enfeksiyonları PP meydana geldiği dönem, semptomun ortaya çıkıp çıkmaması, türü ve şiddetine bağlı olarak metritis, subklinik ve klinik endometritis ve pyometra olarak isimlendirilmektedir. Sürüdeki hayvanların neredeyse yarısını etkileyen PP uterus enfeksiyonlarının hangi tipi olursa olsun, prepartum 3-4 haftalık ve PP 3-4 haftalık süreçte meydana gelen metabolik sorunların birbiriyle ilişkili olarak ve bireyselden çok sürü bazında değerlendirilmesi; ayrıca mikroorganizmaların birbiriyle olan etkileşimleri ve immun yanıtın oluşum mekanizmasının hesaba katılarak tedavi girişiminde bulunulması daha ekonomik ve kontrollü bir yaklaşım olacaktır.

Postpartum Uterine İnfections in Dairy Cows

Öz

Postpartum uterine infections have a great economic importance in dairy cows. The economic impact mostly originates from infertility. Culling of the cow due to infertility, reduced milk production, and the costs of the treatment renders an important problem of the infertility related to uterine infections. The uterine infections are classified as metritis, subclinical/clinical endometritis, and pyometra with regard to the occurrence time on postpartum term, presence/absence of clinical sings, type and severity of infections. Regardless of the pp uterine infection type, it would be more economical and controlled approach to evaluate the problems interrelated with metabolic and uterine pathologies, and on the basis of herd rather than individual cows in 3-4 weeks of prepartum and 3-4 weeks of pp period; also, the treatment strategies should be planned according to interactions of microorganisms and immune response.
