The objective of this study was to investigate the effects of supplementary choline on amount of choline passing to quail meat and reduction of fat deposition in liver. A hundred and thirty-six one-day-old Japanese quails were divided into eight equal groups of 17 quails each. The experiment was designed based on completely randomized design in two controls and six treatment groups: high stocking density, basal diet, control group (HSD; control 1); normal stocking density, basal diet, control group (NSD; control 2); HSD, basal diet + 900 mg kg(-1) choline (A); NSD, basal diet + 900 mg kg(-1) choline (B); HSD, basal diet + 1800 mg kg(-1) choline (C); NSD, basal diet + 1800 mg kg(-1) choline (D); HSD, basal diet + 3600 mg kg(-1) choline (E); and NSD, basal diet + 3600 mg kg(-1) choline (F). Feeds and water were supplied ad libitum. Continuous light was provided. Quails were kept in cages of 50 x 100 cm in size. The choline content of quail meat increased with increasing amount of added choline to feed. The highest choline content (439.2 and 561.2 mg kg(-1)) in quail meat was detected in E and F groups which fed the 3600 mg kg(-1) choline supplemented diet. The total lipid content of liver in E and F groups was reduced by 42% compared with the control groups. We recommend the use of supplementary choline that can improve the amount of choline passing to quail meat and reduction of fat deposition in liver.
