Re-esterified oils contain higher propor- tions of mono- and diacylglycerols and also higher proportions of saturated fatty acids(SFA) at the sn 2 position of acylglycerol molecules than does a na tive oil with the same degree of saturation, which en- hances the apparent absorption of SFA. Moreover, as happens with native oils, their nutritive value could be further improved by blending re-esterified oils of extreme degrees of saturation. Therefore, the aim of the current study was to assess the effect of increas ing the dietary unsaturated-to-saturated fatty acid ra by adding re-esterified soybean oil in replacement of re-esterified palm oil, on fatty acid(FA) apparent absorption and its consequences on growth performance, carcass fat depots, and FA composition of abdominal adipose tissue. For this purpose, one hun dred twenty female broiler chickens were ran domly distributed in 30 cages. The 2 pure re-esterified oils, together with 3 ified oil blends, were i in the basal diet at 6%. The increasing dietary UFA:SFA ratio resulted in an improved total FA apparent absorption linear effect for the starter period, P 0.001; quadratic effect for the grower period, P 0.006) and, therefore, an improved feed conversion ratio(FCR) for the overall period ear effect, P 0.003). In the starter period, the im proved fat absorption was due to the growing pres. of linoleic and the enhanced absorption of SFA, mono- and polyunsaturated FA(associative ef fects among FA; P 0.05). In the growing finishing pe- riod, however, the absorption of mono- and polyunsat- urated FA was not affected(P 0.05). The UFA:SFA ratio of the abdominal adipose tissue varied in the same direction, but to a lesser extent than that of the diet Whilst the deposited-to-absorbed ratio of polyunsat urated FA remained relatively constant as the dietary UFA:SFA ratio increased, the deposited-to-absorbed ra tio of SFA increased, and that of monounsaturated FA decreased. Taken together, the addition of re-esterified bean oil in replacement of re-esterified palm oil im- proved fat absorption, but no synergism was observed between re-esterified oils
