A completely randomized design with five treatments, six replicates and eight B.U.T.6 turkey chickens per replicate was used. Treatments included: Control diet, diet containing 2.5% of soybean oil, diet containing 2.5% fat supplement, diet containing 5% soybean oil, diet containing 5% fat supplement. The results showed that using 5% of soybean oil increased average daily gain of turkeys (89.04 g) throughout the experimental period (0-70 days) compared with the control group (81.11 g; p < 0.05). Treatments containing 2.5 and 5% soybean oil improved feed conversion ratio compared to control group (p < 0.05). Soybean oil at the levels of 2.5 and 5% was led to higher spleen and bursa percentages compared to other treatments, respectively (p < 0.05). The level and source of dietary fat had not significant effect on antibody titer against Newcastle virus vaccine on 42 and 70 days of age (p > 0.05). It can be concluded that supplementing diet with 5% soybean oil improved the performance of turkeys. 2020 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303162575006 https://www.redalyc.org/journal/3031/303162575006/ https://www.redalyc.org/journal/3031/303162575006/html/ https://www.redalyc.org/journal/3031/303162575006/303162575006.epub https://www.redalyc.org/journal/3031/303162575006/movil 10.4025/actascianimsci.v42i1.46775 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
