ABSTRACT Two trials were aimed to evaluate beef tallow in diets with and without emulsifier on performance of pigs at growing-finishing phases. In the first trial, 15 barrows (22.03±0.62 kg) were distributed among three treatments: reference diet; test diet 1 (5% beef tallow) and test diet 2 (10% beef tallow). Beef tallow presented average value of 7130.97 kcal ME/kg. For the performance trail, 30 barrows (24.85±1.18 kg) were distributed among five treatments: T1 - diet with soybean oil and 3230 kcal ME /kg; T2 - diet with beef tallow and 3230 kcal ME/kg; T3 - diet with beef tallow and 3080 kcal ME/kg; T4 - diet with beef tallow, 3080 kcal/kg and 0.1% emulsifier; T5 - diet with beef tallow, 2930 kcal ME/kg and 0.1% emulsifier. Feed conversion was worse in animals fed diet with 3080 kcal ME/kg containing beef tallow and with 2930 kcal ME/kg with beef tallow and emulsifier. For economic availability, animals fed diet with beef tallow and 3230 kcal ME/kg and those fed diet with 3080 kcal ME/kg containing beef tallow and emulsifier, did not differ from animals fed diet with soybean oil, which enables the reduction up to 150 kcal ME/kg be compensated by emulsifier addition.
