One hundred and twenty eight 8 days-old Vencobb broiler chicks were fed ad libitum on either of 4 iso-nitrogenous and iso-caloric diets containing 0, 4, 8, and 12% duckweed meal (DWM) up to 42 days of age to see the effect on growth performance and profitability. Body weight, feed intake, feed efficiency, protein efficiency, energy efficiency and profitability linearly declined as the proportion of DWM increased in the diet. Duckweed did not affect on livability (P>0.05). From the above findings it can be concluded that the inclUSion of DWM in the broiler diet is not recommended. However, further study is needed to give final recommendation to use duckweed (Lerona minor) meal at a low level as an unconventional feed ingredient for broilers.
