Abstract

A replicated 3 x 3 Latin square experiment utilizing nine barrows fitted with ileocecal simple T-cannulae was conducted to determine protein and energy utilization in two samples of OAC Wintri triticale (triticale A, 15.5% and triticale B, 10% protein on a dry matter basis) and compare them to corn. Apparent fecal and ileal digestibilities of dry matter, gross energy and ether extract were greater (P<.05) in corn than either sample of triticale. Fecal and ileal digestibilities of dry matter and gross energy were greater (P<.05) in triticale A than in triticale B. Apparent fecal nitrogen digestibility was similar (P>.10) between corn and triticale A but lower (P<.05) in triticale B. Ileal nitrogen digestibility decreased (P<.05) in the following order: corn > triticale A > triticale B (79 > 75 > 67%). True fecal nitrogen digestibilities, determined by feeding the barrows a "nitrogen-free" diet were 89, 87 and 78% in corn, triticale A and triticale B, respectively. Net protein utilization and biological value were not different (P>.10) among grains. Digestible energy decreased (P<.05) in the following order: corn > triticale A > triticale B (4.08 > 3.77 > 3.56 kcal/g). Metabolizable energy (ME) and nitrogen-corrected ME were greater (P<.05) in corn (3.66 and 3.62 kcal/g) than either sample of triticale, but were similar (P>.10) between triticale A and triticale B (3.19 and 3.13 vs 3.12 and 3.08 kcal/g, respectively). The ME values were determined with the grain as the only source of protein and energy, and may not represent the true values when fed in a balanced diet. Chromic oxide index and total collection provided similar (P>.10) estimates of fecal dry matter, energy and nitrogen digestibilities in corn; however, these response criteria were consistently underestimated (P<.05) by chromic oxide index in both triticales.
