Abstract


This study aimed to evaluate the viability of using four lipid products (refined soybean oil, RO; degummed soybean oil, DO; pig lard, PL; and recycled frying oil, FO) as ingredients for pig feed during the finishing phase. The products were previously evaluated for the presence of insoluble impurities, peroxide levels, and total acidity as well as dioxin group, polychlorinated biphenyl, and polycyclic aromatic hydrocarbon contaminants. Eighty 110 day-old pigs, including 40 castrated males and 40 females, with a mean initial weight of 59.01 ± 5.09 kg, were subjected to four treatments (feed containing RO, DO, PL, and FO) for 32 days to evaluate the effect on growth performance, carcass and meat traits and adipocyte diameter. The results for the products did not reveal any degradation or presence of contaminants within the use restriction levels. There were no differences regarding performance, carcass and meat traits, and adipocyte diameter among the treatments. The animals fed FO feed exhibited a poorer loin area and marbling (P < 0.07). The tested lipid raw materials are viable for use as ingredients in feed.
