DIGESTIBILITY AND ACCEPTABILITY OF OAC WINTRI TRITICALE BY GROWING PIGS

The digestibility and acceptability of OAC Wintri triticale were evaluated in two trials. In trial 1, three diets in which triticale replaced 0, 50 or 100% of corn were fed to 12 barrows individually housed in digestion crates. No significant difference was observed in dry matter digestibility among diets. Daily fecal nitrogen, daily absorbed nitrogen and apparent protein digestibility adjusted to equal nitrogen intake responded quadratically (P < 0.01) to increasing levels of triticale in the diets. There were no significant differences in daily retained nitrogen, apparent biological value or net protein utilization among diets. Gross energy digestibility, digestible energy (MJ kg−1) or metabolizable energy (MJ kg−1) were not different among diets. The second trial involved pair-feeding 48 pigs (average initial weight 36.7 kg) for 28 d to ascertain the acceptability of triticale to pigs utilizing the same diets as in trial 1. Increasing levels of dietary triticale resulted in a linear reduction (P < 0.00...
