Uniformity is generally assessed visually and subjectively, as to do the job properly would require individual weighing of hundreds of broilers (in the absence of automatic weighers). The level of uniformity basically dictates the final result; poor flock uniformity goes hand in hand with delayed growth, rejects, and poor FCR.
The processing plant requires uniform flocks with the correct average bodyweight to satisfy the demands of the modern distribution network.
When a broiler flock is processed a complete histogram on the range of carcass weights can be produced. The percentage of carcasses within the desired weight range is a very important measure for the processing plant.
In the end, uniformity is a good indicator of the production process; in fact all technical or health problems, starting from the day old breeder up to the broiler delivered to the processing plant, impacts the broiler uniformity at the time of slaughter.
