The purpose of this study was to investigate goose growth and feather characteristics are influenced by its lines and feeding surroundings, inclusive of floor materials and types. Whereas, there is no any reports regarding to it, hence, this study is investigated to realize this issues.
The 240 White Roman geese which were hatched by sex identification from 3 commercial goose farms, and they were randomly distributed to 24 pens depending on a completely random design. The study is including 3 lines from commercial geese and 2 floor types (Cement strip floor (CSF) or Cement floor (CF)) treatments raising for 13 weeks.
The day one gosling weight from A farm had lower than other two farms (96 g vs. 107 and 115 g; P<0.001). Afterwards, the body weight, back length, keel length, chest girth and main wing feather length among 3 farms showed no any significance prior to 12 weeks. The CF group shared heavier body weight, shorter back length, longer keel length, shorter chest girth and shorter main wing feather length than the other CSF group prior to 12 weeks. The down weight in the CF shared heavier than the other CSF group (57.1 g vs. 41.8 g; P<0.01) prior to 13 weeks.
The body weight shared the positive relations for dry feather weight (r=0.59), down weight (r=0.69), percent of the down weight of live body weight prior to 13 weeks (r=0.61).
