Abstract: This study has been done to determine to effect of force-feeding on fatty liver production and blood parameters of native and Romanov geese. In the study; 22 native and 18 Romanov adult ganders were used. Cramming period lasted 35 days. In the blood samples taken different part of the study, were analysed for fatty acids, like triglyceid, cholesterol, HDL and LDL and hepatic enzymes, like SGOT, SGPT and ALP. Fatty acids levels increased with the paralel accumilation of fat in the body and also hepatic enzyme levels increased paralel with the tissue destruction. Carcas, fatty liver and abdominal fat content of Romanov and native geese were 5300.00±225.30 - 4085.55±279.98 g, 350.32±18.12 - 277.36±8.06 g and 722.22±44.18 - 509.54±83.08 g respectively. Lauric, myristic, palmytic, stearic, oleic, linoleic, acid contents of liver samples of treatment goups were statisticaly different than the control group. While fat content of control groups liver samples were determined 4.73±0.57 and 4.80±0.40%, Romanov and native treatment groups were 38.79±0.94 and 37.50±0.74 respectively. In the liver samples, opposit with protein and ash content, dry matter level increased with the fat content. Due to lower body weight and could not charge to force-feeding, using native geese to produce fatty-liver may not be feasible, as a conclusion.
