- Abstract
The purpose of this study was to investigate the effects of composite floors on mule duck's growth performances. 240 three weeks old mule ducklings were allocated randomly into 4 treatment groups including half stainless mesh floor with half rice hull, half plastic floor, half wooden slats floor, or half non-slip rubber floor. Three replicates per treatment, 20 ducks per replicate. Ducks growth performance was determined at 3, 7, 10 and 12 weeks of age. The results showed that body weight at 12 weeks of age was in the range of 3,105 to 3,283 g. The body weight of ducks raised on the half non-slip rubber floor group was 3,105 g and significantly lower than the other three groups (P < 0.05). The primarily feather length at 12 weeks of age was in the range of 20.8 to 22.6 cm. The primarily feather length of ducks raised on the half non-slip rubber floor group was 20.8 cm and significantly shorter than the other three groups (P < 0.05). The foot pad damage score at 12 weeks of age of ducks raised on the rice hull treatment was 0.4, significantly better than the other three groups (P < 0.05). According to the results of this experiment, it is recommended to apply the half stainless mesh floor with half rice hull in the duck house when ducks' live body weight, primarily feather length, footpad damage were taken into consideration simultaneously.
