Abstract

Three varieties of triticale, ranging in crude protein content from 108 to 192 g kg−1 DM, were compared with wheat in digestibility trials conducted on sheep, pigs, chicks and cockerels to estimate metabolizable energy (ME) for sheep and poultry and digestible energy (DE) for pigs. Classical balance trials were conducted on sheep, pigs and chicks, but ME was determined in cockerels by the true ME method.

In sheep, all cereals had similar ME values (13.03 MJ kg−1 DM). In pigs the mean DE value of the triticale varieties was significantly lower at 15.11 MJ kg−1 DM than the value of 16.03 MJ kg−1 DM for wheat, however, differences between the triticale varieties were small and non-significant. In poultry, as with pigs, wheat had a significantly higher ME than triticale. For chicks, the ME value of one variety of triticale was significantly lower than all others, but, with cockerels, there were no differences in ME between the three varieties of triticale.
