- Abstract
The aim of this study was to investigate the effects of dietary content of phytase on growth performances and blood characteristics in indoor-reared White Roman geese during growing periods in hot seasons. Ninety-six of 28-day-old White Roman geese were randomly divided into 4 levels of dietary phytase with 0 (A group, control group), 500 (B group), 1,000 (C group) and 1,500 (D group) FTU/kg. Each treatment was allotted 3 pens with 8 geese per pen (4 males and 4 females). The geese were raised in the indoor geese house from 29 to 56 days of age. The environmental temperature was between 25.0 to 38.0°C. The results showed that there were no differences in body weight, feed intake, feed efficiency and body temperature among the groups. However, geese raised in group D showed significantly higher serum superoxide dismutase activity compared with that of group A. In summary, the addition of phytase may reduce the activity of superoxide dismutase of serum in indoor-reared White Roman goose.
