Abstract:

Abstract: One-factor experiment was designed to investigate the effect of capsicum, allinin and vitamin C on growth performance and slaughter characteristics in Jiaji ducks in the first growth stage, one-day-old Jiaji ducks were randomly divided into four groups by weight. Ducks were fed basal diet, basal diet+0.4% capsicum, basal diet +0.01% allinin, basal diet+0.1% vitamin c respectively. Every group included three replicates and each replicate with sixteen birds. The experiment conducted for 70 days. The result showed that all additives could improve growth rate in each stage of experiment, the three kinds of additives could improve slaughter characteristics to some extent, decrease significantly sebum deposition. It was recommended to add capsicum, allinin and vitamin c to improve performance and increase the economic efficiency of production in Jiaji ducks in the first growth stage.
