Effects of Star Anise and Its Essential Oil and Leavings on Growth Performance, Intestinal Development and Nutrient Digestibility of Broilers
摘要
Abstract
This study was conducted to investigate the effects of star anise (lllicium verum Hook.f.) and its essential oil and leavings on growth performance,intestinal development and nutrient digestibility of broilers.Three hundred and eighty-four 1-day-old male Arbor Acres broilers were randomly allocated to 4 groups with 12 replicates of 8 broilers in a single factor complete randomized design.Broilers in control group were fed a corn-soybean meal type basal diet,and broilers in experimental groups were fed the basal diet supplemented with 5 g/kg star anise (star anise group),0.2 g/kg star anise essential oil (essential oil group),and 5 g/kg star anise leavings (leavings group),respectively.Trans-anethole content in diets for star anise group and essential oil group was 0.204 g/kg,and that in diets for control group and leavings group was less than 0.005 g/kg.The experiment lasted for 21 d.The results showed as follows:1) the average daily gain and average daily feed intake in star anise group and essential oil group were significantly higher than those in control group (P＜0.05),but no significant differences were found between leavings group and control group (P＞ 0.05).Compared with control group and leavings group,the body weight at 21 days of age was significantly increased in star anise group and essential oil group (P＜0.05).2) Compared with control group and leavings group,the relative length of jejunum in star anise group and essential oil group was significantly higher than that in control group and leavings group (P＜0.05),and the relative weight of small intestine in essential oil group was significantly higher than that in control group and leavings group (P＜0.05).Moreover,the relative weight of jejunum in star anise group and essential oil group was significantly higher than that in control group (P＜0.05).3) Compared with control group and leavings group,supplementations of star anise and star anise essential oil could significantly increase the villous height of duodenum and jejunum (P＜0.05).4) The apparent and true digestibility of crude protein and apparent and true metabolic energy in essential oil group were significantly higher than those in other groups (P＜0.05).In conclusion,supplementation of 5 g/kg star anise or 0.2 g/kg star anise essential oil can improve growth performance,intestine development and the nutrient digestibility and utilization of broilers,but the 5 g/kg star anise leavings has no effect.关键词
