植物精油和有机酸对21至35周龄蛋鸡生产性能及蛋品质的影响
Effects of Essential Oil and/or Organic Acids on the Performance and Egg Quality of Laying Hens from 21 to 35 weeks
摘要
Abstract
This experiment was conducted to study the performance and egg quality of laying hens from 21 to 35 weeks with diet supplementing essential oil or organic acid or esssential oil and organic acid complex as green feed additives.A total of 504 21-week-old laying hens were randomly allocated to 4 groups,with 7 replicates per group and 18 chicken per replicate.The experiment lasted 15 weeks and the treatments were designed as follows:control (basal diet),control diet supplemented with essential oil (basal diet + 300 mg/kg essential oil),control diet supplemented with organic acid (basal diet + 300 mg/kg organic acid),control diet supplemented with essential oil and organic acid compound (basal diet + 300 mg/kg compound of organic acid and essential oil).The results showed supplementing essential oil or organic acid or complex had no significant effect on laying rate,egg weight,daily feed intake and feed to egg ratio of 21～27 weeks old and 28～35 weeks old laying hens (P＞0.05).Adding plant essential oil to the diet significantly improved the yolk color of laying hens at week 27 of age (P＜0.05).The supplement of essential oil,however,could improve yolk color of laying hen aged 35 weeks (P＜0.05).There was no significant difference on eggshell thickness,eggshell strength,egg albumen height and Haugh unit between groups (P＞0.05).Supplementing essential oil or organic acid had no effect on performance of laying hen at 21～35 weeks,and essential oil supplemented alone in diet could improve yolk color of laying hens at 35 weeks.关键词
