摘要：The core objective of this study was to assess the effects of different dietary Leucaena leucocephala seed on the performance and some blood parameters in broiler chick. Seeds were included at 0, 3, 6, 9 and 12% in the diet of one hundred twenty one-day-old unsexed broiler chicks. The results showed that, feed intake, body weight gain and PER were significantly (p 0.01) depressed with the inclusion of 6, 9 and 12% leucaena seeds in the diet. Feed intake, body weight gain and PER were negatively correlated (p 0.05) with levels of inclusion of leucaena seeds. However, overall FCR, haematological parameters , plasma albumin, glucose and mortality rate were not influenced (p > 0.05) by dietary treatments. Inclusion of dietary leucaena significantly decreased plasma Ca, Na, total protein and cholesterol. While plasma Glutamic oxaloacetic transaminase GOT, alkaline phosphatase ALP and uric acid were increased with the increase in levels of leucaena in the broiler diets.
