Determination of optimal standardized ileal digestible lysine to metabolizable energy ratios in diet for cobb 500 broilers from 1 to 14 days of age

In this study, 400 day-old straight-run Cobb 500 broiler chicks sourced from a commercial hatchery were randomly allotted to treatment following a Randomized Complete Block Design (RCBD). The treatments used were fivve ratios of SID Lysine (Lys) to metabilizable energy (ME) in diet of 3.61, 3.89, 4.17, 4.45, or 4.73 g SID Lys/Mcal ME.
