Four thousands of 1-day-old Arbor Acres broilers were randomly divided into four groups (1 000 for each), i. e., one group was fed with basal diet as the control, and the other three were fed with basal diet added with 1.0%, 2.0% or 3.0% of enteromorpha as treatment groups. After 42 days of feeding trial, broilers in three treatment groups all gave a significantly increased average daily weight gain and feed to gain ratio in comparison with the control group (P 〈0. O1 ) ; within treatment groups, those added with 3.0% enteromorpha assumed a significantly higher average daily gain and feed to gain than with 3.0% enteromorpha (P 〈0.05), while an insignificantly difference with 2.0% enteromorpha group ( P 〉 0.05 ). The results indicated that adding appropriate amount of enteromorpha can facilitate the improvement of broiler performance.展开更多
