Abstract

This experiment was conducted to study effects of rearing system on growth performance, plumages development and leg health of Sichuan white meat geese aged from 2 to 10 weeks. Four hundred and thirty two healthy 14-day-old Sichuan white meat geese with similar body weight were used in a single factorial design trial and randomly allocated into 3 groups with 6 replicates in each group and 24 geese in each replicate. The 3 groups of geese were raised in 3 rearing system, they were net combining ground rearing (NGR), net rearing (NR), and deep-litter rearing (LR), respectively. The feeding experiment lasted for 56 days. Twelve geese per group were picked up on the basis of individual weight immediate to the average weight of every group on 70 days of the experiment were used in a slaughter test, and meanwhile the body weight, feed consumption, length and width of primaries, and health indicators of geese were measured on that day. The results showed as follows: rearing system had significant effects on the final weight, average daily gain and daily feed intake (P<0.05 or P<0.01), and LR > NR > NGR. The dressed percentage, percentage of hal-eviscerated yield, percentage of abdominal fat and heart index of LR were significantly higher than those of NGR (P<0.05), the percentage of head of NGR was significantly higher than those of NR and LR (P<0.01), and the percentage of foot of NGR was significantly higher than that of LR (P<0.01), the proventriculus index of NGR was significantly higher than that of NR (P<0.05). The average length of primaries of NGR was significantly lower than that of LR (P<0.05), the average width and the ratio of average width to length of primaries were significantly higher than that of NR and LR (P<0.01), and the plumage scoring of NGR was significantly lower than that of NR and LR (P<0.01), the weight of 100 plumages of NR was significantly higher than that of LR (P<0.05). The gait scoring of LR was significantly lower than that of NR (P<0.05), and the foot pad scoring of LR was significantly lower than that of NR and NGR (P<0.05). The results suggest that for rearing system of meat geese, NR can improve performance of geese, NGR can improve plumage development and healthy of geese, and LR can make the leg and foot of geese more healthy.
