Abstract
A 35- day feeding trial was conducted to study the effects of inclusion of Asystasia gangetica leaf meal (AGLM) on the growth response of broiler chickens. Samples of Asystasia gangetica leaves were sourced from the Federal University of Agriculture, Abeokuta environment. The leaves were chopped and wilted, sun dried to reduce the moisture level to the minimal level. The dried leaves were milled to produce leaf meal. Asystasia gangetica leaf meal contain 19.38% crude protein, 15.30% crude fibre, 12.70% ether extract, 1.70% ash and 36.34% NFE. A total number of 120 day old Marshal Strain of broiler chicks was used. A standard starter diet was fed to the birds prior to the commencement of the experiment. At the end of the 3rd week, birds were allotted into four treatments having three replicates of 10 birds each. Four experimental diets were formulated with varying levels of A. gangetica leaf meal (0, 2.5, 5.0 and 7.5 %) respectively. Final live weight and daily weight gain varied significantly (P<0.05) among treatment groups. The feed intake and feed conversion ratio were not significantly influenced (P>0.05) by dietary treatments. Final weight and weight gain values were found to decrease across the dietary treatments with increasing level of A. gangetica leaf meal. The results of the experiment show that the use of A. gangetica as feed ingredient in broiler production significantly depressed growth.Â
