2 Abstract: A study was conducted to estimate broiler production functions based on data obtained from broiler enterprises around the Calabar municipality of Cross River State, South Eastern Nigeria. The data were analyzed using the mean difference model as well as the ordinary least square's regression methods to estimate linear, double log, exponential and semi-log functions. The linear model provided the lead equations for the first four and second four weeks, while the double log model provided the lead equation for the entire eight weeks of rearing broilers. The study showed that the mean feed intake per bird, body mass gain and mortality rate of birds in the surveyed area differed (P |
