植物提取物添加剂对肉鸭生产性能及水便与软便率影响的研究

Effect of Oregano Essential Oil on Production Performance and Wet Litter in Meat Ducks

应用植物提取物添加剂替代对照组肉鸭饲料中常用抗菌药物,并分3个水平适当降低油脂用量,研究植物提取物对肉鸭肠道菌群的改善(以粪便的水便率和软便率作为评估指标)以及生产性能的影响,同时进行经济效益分析。试验选用1日龄5040只樱桃谷肉鸭,42d试验期。结果表明:相比于对照组,植物提取物(好力高)试验组肉鸭水便率与软便率显著降低(P<0.01),饲料转化效率显著改善(P<0.01),明显提高生产性能和经济效益(P<0.01)。同时,在肉鸭饲料中添加植物提取物后适当降低油脂添加量,不仅可以降低饲料配方成本,而且全期饲养生产性能指标还有较好改善,经济收益有明显的提高。

The purpose of this study was to investigate the ceffects of supplementation of Orego-Stim （Meriden）in duck feed as an alternative to antibiotic growth promoters （AGPs） while replacing the fat in the diet on gut microflora,production performance and evaluation of economy benefits. The control group was fed a basic diet and three trentment groups were fed diets reducing dietary fats at three levels. Five thousand and forty one-day-age Cherry Valley ducks were seleted and divided into four groups for this study and the trial period was 42 days. The results showed that supplementation of Orego- Stim significantly reduced the incidences of wet litter and soft droppings （P 〈0.01） ;improved FCR and production performance significantly （P〈0.01） with better economical benefits comparing with the control group. The results also demonstrated that the peroformance of ducks fed diets with reducing fats but supplementing Orego-Stim was the same as that of control group.
