Lysine requirements of growing emus

1. The lysine requirement of growing emus between 23 and 65 d of age was determined according to growth response variables. 2. The optimal lysine requirement of emus was found to be 0(.)83 and 0(.)90 g/MJ ME for growth rate and gain:food ratio respectively. These findings are in accordance with the...

Description
Summary:1. The lysine requirement of growing emus between 23 and 65 d of age was determined according to growth response variables. 2. The optimal lysine requirement of emus was found to be 0(.)83 and 0(.)90 g/MJ ME for growth rate and gain:food ratio respectively. These findings are in accordance with the recommended value of 0(.)80 g/MJ ME, but is lower than the recommended value for ostriches (1(.)02 g/MJ ME) and higher than determined values for broilers (0(.)75 g/MJ ME) of the same age range.
