dc.description.abstract <p>1. New production processes and additional uses for corn co-products have increased the availability of distiller’s dried grains with solubles (DDGS) with varying energy and amino acid digestibility, for use in poultry feed. The objective of this study was to determine the performance, N-corrected metabolisable energy (AMEn), and amino acid (AA) digestibility of a 34% CP (as fed) high-protein DDGS (HP-DDGS) included in poultry diets for Cobb 500 broiler chickens.</p> <p>2. A total of 832 Cobb 500 broilers were randomly assigned to four dietary treatments containing 5% conventional DDGS (CV-DDGS) as a control or 10, 15, and 20% HPDDGS and fed for 42 d. After the performance trial, 240 birds from the original 832 were selected for a concurrent AMEn and AA digestibility experiment consisting of two AMEn diets and two AA diets.</p> <p>3. Birds fed diets containing 15 and 20% HP-DDGS gained less weight than birds fed the CV-DDGS (P <0.05) but did not differ in feed intake (FI), and therefore had a less efficient FCR than the control (P<0.05). The AMEn of HP-DDGS was determined to be 11.4 MJ/kg. The standardised ileal amino acid digestibility (SIAAD) of the essential amino acids Lys and Met were determined to be 80.9 and 88.6%, respectively.</p> <p>4. HP-DDGS can be included in broiler diets up to 10% without any negative impact on performance or requiring supplemental Lys and Arg. The results from the AA digestibility study indicated that HP-DDGS could be a good source of digestible Lys.</p>
