Fatty Liver Syndrome in Dairy Cattle: Relation between Nefa, Apo-A, Ammoniac, Tsh and Total Bilirobin Serum Values in this Syndrom

Fatty liver syndrome (Hepatic lipidosis) or fat cow syndrome is a major metabolic disorder in many dairy cattle's in early period of lactation. The aim of this study was to evaluating fatty liver syndrome in dairy cattle in Tabriz by measurement of NEFA, APO-A, Ammoniac, TSH and Total Bilirobin serum values. In this study 10 mL blood samples from 400 Holstein dairy cows were obtained by venoject from jugular vein and then samples in vicinity of the ice sent to the laboratory. In lab, prepared serums froze inside the micro tube. The results showed that NEFA has a positive relationship with ammoniac and total Bilirobin serum values and reverse relationship with APO-A and TSH. Thus, with elevating of NEFA serum values, ammoniac and total Bilirobin also increased and TSH and APO-A contrary diminished.
