Figure 1: Hepatic ultrasonograms in 3 cows during the transition period. Images were taken 3wk before expected parturition (a, d, g), at parturition (b, e, h) and 3wk after parturition (c, f, i). With increased liver triglyceride (TG) content in cow 1 (a, b, c), hepatic ultrasonography showed a gradual increased echogenicity with vascular blurring. In cow 2 (d, e, f), with increased hepatic TG content hepatic echogenicity increased at parturition and then declined 3wk after parturition parallel to TG content. In cow 3 (g, h, i), hepatic echogenicity increased also with increased hepatic TG content.
