Sunflower seed to swine on growing and finishing phase: digestibility, performance and carcass quality/ Grão de girassol na alimentação de suínos em crescimento e terminação: digestibilidade, desempenho e efeitos na qualidade de carcaça

Two experiments (a digestibility and a performance tests) were carried out to evaluate sunflower seed (SS) as swine feeding on growing and finishing phases. To performance evaluation 48 pigs, with 19.78 kg liveweight were allotted to four treatments (diet without SS, 5%, 10% and diet with 20% of SS) and they were evaluated during four periods (growing I and II, finishing and total period). All animals were slaughtered and submitted to an electronic carcass evaluation at the end of the experiment. The digestible and metabolizable energy values of SS were 3234 and 3223 kcal/kg, respectively. There were regression effect (P
