Effects of different rearing systems on growth performance, carcass traits, meat quality and serum biochemical parameters in Gaoyou ducks

Context The rearing system is a critical non-genetic factor that can considerably affect poultry production. Aims This study examined the effects of floor systems (FRS), net and cage (CRS) on growth performance, carcass traits, meat quality serum biochemical parameters Gaoyou ducks. Methods A total 450 healthy 22-day-old male ducks with similar average bodyweight were randomly divided into FRS, CRS groups. experiment lasted from 22 to 84 days age. Key results had higher final bodyweight, daily feed intake gain, lower feed-to-gain ratio P < 0.05). FRS breast gizzard yields shear force, drip loss abdominal fat content (P Moreover, significantly glucose, protein triglyceride, high-density lipoprotein cholesterol levels Conclusions was beneficial performance ducks, whereas some parameters. Implications indicated their own advantages. Thus, an appropriate should be selected according production target market demand.
