Abstract

A metabolism trial was carried out with 95 male broilers, 24 day-old, of commercial line, subjected to 18+1 treatments with 5 replications. Three levels of free fat acid (FFA) inclusion by the usage of soybean oil (SO), acidulated soybean soapstock (ASS), and the mixture between the two oils (50:50%), in two levels of inclusion (4 and 8%) in the basal diet (BD) and the supplementation of glycerol or emulsifier (0.5%), in substitution to starch were tested. The trial was conducted for 8 days. Birds performance, metabolizability coefficient of dry matter (MCDM), fat (MCCF) and energy (MCCE) were evaluated and the comparison among oils and supplements. The performance and the metabolism were not affected (P>0.05) by FFA levels or supplements tested.  It was observed that the use of lecithin improved added crude fat metabolism (P<0.01) and that birds used equally SO and ASS. Both SO and ASS are good sources of fat for broilers.

KEY WORDS: Acidulated soybean soapstock, emulsification, lecithin, metabolism, performance.
