Investigation about Fatty Liver Syndrome Prevalence in Dairy Cattle of Rasht Township Slaughterhouse (Ghilan Province, Iran)

Fatty liver syndrome or hepatic lipidosis occurs when the received energy by animal is lower than the consumed energy especially during lactation. In this case, body fats will become lipolysis because of negative balance of energy then flow to the liver so, inevitable troubles will appear such as abomasums displacement, placenta remaining, post partum hypocalcaemia and reduction of body immunization, etc. In this study, 96 heads of hybrid and healthy dairy cattle of 3-5 years old with body score of 2 and 3 were used and the blood and liver samples were obtained with the rate of 10 cc and 20 g, respectively in order to investigate fatty liver syndrome. The amount of NEFA, glucose and albumin in serum and the amount of liver cells TAG in liver samples were measured. The results suggest that there is meaningful increase in serum NEFA (1082±432.88 μ Eq L 1) and liver TAG (7.73 1.68%) and meaningful decrease in serum glucose (37.20 15.26 mg dL 1) in new-calved cattle (p<0.001). Also, serum albumin in new calved cattle and last months pregnant cattle in which the NEFA serum and liver fat were in highest levels, sowed meaningful decrease (p<0.01).
