Süt Sığırı Çiftliklerinde Rasyon Yağ Asitleri ile Süt Üre Azotu ve Fertilite Sorunları Arasındaki İlişkinin İncelenmesi

Bu çalışmanın amacı, süt sığırı işletmelerinde postpartum dönemde rasyonun besinsel değişkenleri ile döl verimi arasındaki ilişkiyi göstermekti. Çalışmada kullanılan süt sığırı işletmelerinin hepsinde infertilite sorunu (buzağılama aralığı ≥14 ay ve suni tohumlama sayısı ≥1.8) vardı. Seçilen süt sığırı işletmelerinde rasyon ve süt örnekleri alındı. Sürü kayıt sistemlerinden fertilite kayıtları incelendi. Çalışmada, süt örneklerinin süt üre nitrojeni (MUN) seviyeleri işletmeler arasında değişkenlik göstermekle birlikte; 7.37 ve 32.92 mg/dL arasındaydı (P

Investigation of Relationship among Dietary Fatty Acids and Milk Urea Nitrogen and Fertility Problems in Dairy Cattle Farms

This aim of this study demonstrated the relationship between the nutritional variables of ration and the fertility parameters in the postpartum period in dairy cattle farms. All dairy cattle farms, which used in present study, were with fertility problems (calving range ≥14 months and artificial insemination number ≥1.8). Ration and milk samples were taken from selected dairy cattle farms. Fertility records from herd registration systems were examined. In the study, milk urea nitrogen (MUN) levels of the milk samples were different between the farms; the lowest was 7.37 mg/dL, and the highest was 32.92 mg/dL (P
