This research aims to evaluate the effects of growth period and energy evaluation methods on amino acid digestibility and metabolisable energy in broiler chickens.
480 male Ross 308 broilers, aged 5 days, were allocated to six diets including maize, wheat, and barley.
Diets were tested using total collection and indigestible marker methods.
A randomised complete block design was implemented with eight pen replicates for each treatment.
The total collection method yielded higher metabolisable energy estimates compared to the indigestible marker method (p < 0.05), especially for barley and wheat.
Fine wheat flour demonstrated the highest ileal digestibility of amino acids (p < 0.05), outperforming other cereals.
Both metabolisable energy and ileal amino acid digestibility improved during the grower period, influenced by cereal type and processing method.
