A Comparative Study Between the Effects of Rice-duck co-cropping and captivity on the Performance of Hemp Duck
This study aimed to evaluate and compare the effects of rice-duck co-cropping and captivity on the performance of hemp duck,in order to lay a theoretical basis for the ecological farming of ducks.A total of 400 one-day-old male ducks from a commercial hatchery were randomly divided into two groups:a rice-duck co-culture group(density of 30 ducks/m2)and a captive group(density of 10 ducks/m2),with 10 replicates in each group and 20 ducks in each replicate.The experimental duration was 49 days.The 20 ducks were divided into 10 wire floor fences for a total of 200 ducks in captive group,and another 200 were stocked in paddy fields as rice-duck co-culture group.At the age of 49 days,performances including body weight and feed intake were measured.Results showed that the daily gain,daily feed intake and body weight of the rice-duck co-culture group were significantly higher than those of the captive group(P<0.001),while the feed-to-gain ratio of the captive group was significantly higher than those of the rice-duck co-culture group(P<0.001).In conclusion,the rice-duck co-culture model could improve performance of ducks,reduce feed consumption,and improve economic profit.
