Short summary
In this study, the effects of using soy oil (SO), poultry fat (PF) and tallow (T) in feed at fixed energy : protein ratio on broiler performance were evaluated. When PF and T were used instead of SO, especially in grower feed, the field performance improved except for mortality. This situation was not seen in slaughter performance except for a few cases. At the end of the study, it was seen that if certain ratios are not exceeded, the use of PF and T instead of SO may be economic alternatives.
