Abstract
Studies were conducted to determine if specific parameters could be measured which would indicate the degrees of liver damage in fatty: liver syndrome in the laying hen. The first study was conducted with 24 hens from a flock which had completed 11 months of production on a diet considered complete by nutritional standards. These birds had a history of mortality from I liver steatosis and hemorrhage. Liver damage, as indicated by SGOT; level and the formol gel test, was studied in relation to parameters used to indicate fatty liver syndrome. A second study was conducted to determine the liver ultrastructure of hens which had liver damage as indicated by high SGOT levels. A third experiment was designed to determine the efficacy of a lipotropic mix by measuring the effect of the lipotropic mix¹ on SGOT levels, serum albumin and globulins, measurements of liver steatosis, and liver hemorrhage scores. Biopsy of the liver allowed a histological score, based on vacuolation of the liver, before and after the experimental treatments were applied. This also provided for electron micrographs. Twenty-seven hens were fed a basal diet or a basal diet plus a lipotropic mix for a period of 25 days with production parameters collected during this period. At the end of a two-week period, hens were biopsied to obtain sections for electron micrographs..
