Light stimulation should be done based on the flock’s body weight and uniformity. Uniformity did not influence cumulative egg production, egg weight, fertility, or mortality. One. The CV is expressed as a percentage of the mean and can be calculated by dividing the standard deviation by the average BW and multiplying the result by 100 (Cobb-Vantress, 2008b ). In general, uniformity decreases with increasing age in mixed-sex flocks, due to the. 50 g/kg to low energy and protein broiler chicken diet improved flock uniformity as well as metabolizable energy, CF and protein. Whilst only one flock significantly changed its flock uniformity with time, they differed from each other in uniformity and body weight (P = 0. 001) starter FCR, while grower and finisher FCR were not impacted. Flock uniformity plays a major role in proper management of breeder flocks. intake, weight gain and flock uniformity. It is suggested that despite some stresses, commercial.
