【Abstract】 This trial was conducted to determine performances of multiplication strains of TD lean duck.The results showed that the parent stock could produce more than 260 eggs and 190 vigorous ducklings one year.The commercial stocks crossed two male lines F 4 ,F 6 selected with three female lines lines E 3C ,E 3D ,E 3W selected had a good meat performance.The average live weight of the ducks was 2264-2360 g,and feed conversion ratio (2 40-2 56):1 at the age of six weeks.The percentage of subcutaneous fat,breast muscle yield and lean of the duck at the age of eight weeks,was 19 0%-23 4%,14 5%-16 3% and 30 1%-32 1%,respectively.更多还原
