Abstract：In this study, the effects of cage and floor rearing system on the survival rate, growth performance and blood antioxidant indexes of Magang goose during the growth period were tested. The aim was to reveal the effect of cage rearing system on the output return of meat goose. The results showed that during the whole trial period, the death and culling rate of goose in the cage group was 17%, which was significantly higher than that in the floor group (9%). Before 3 weeks of age, the growth performance of the cage group was similar to that of the floor group, and the cage group was slightly better than the floor group. The mean body weight and feed conversion rate of the cage group were also higher than those of the floor group within 3 weeks. However, after 3 weeks, its growth performance was significantly inhibited, and the body weight gain, feed conversion rate and most body measurements were significantly lower than those in the floor group. In the cage group, the levels of blood antioxidant Glutathione reductase (GR), Superoxide dismutase (SOD), Malondialdehyde (MDA) were increased, compared to those in flat culture while Catalase (CAT) was reduced. The results showed that the cage rearing system was more beneficial to the growth performance and feed conversion of goose than the floor rearing system before 3 weeks.After three weeks of age,affected by space constraints and environmental stress, the floor rearing system had more obvious advantages on the growth performance of meat goose compared to the cage rearing system.
