The impact of the degree of saturation
of fatty acids and their chain length on ME has been
well-documented in broilers (Wiseman and Salvador,
1991; Blanch et al., 1996; Sanz et al., 2000; Villaverde
et al. 2006; Smink et al., 2010). In general, a higher degree
of saturation and increasing fatty acid chain length
leads to poorer digestibility of the fat source.
