AQUINO, T.M.F. et al. Inclusion levels of parboiled rice bran in piglet diets in the nursery phase. Arq. Bras. Med. Vet. Zootec. [online]. 2014, vol.66, n.5, pp.1531-1538. ISSN 0102-0935.

Two assays were conducted to evaluate the parboiled rice bran in piglet's diets in the nursery phase. In the first, 14 male castrated piglets were allotted to determine the nutritional value of parboiled rice bran in a digestibility assay. A completely randomized design, with 2 treatments and 7 replicates per treatment were used. The parboiled rice bran presents 17.15% of CP and high fiber content (33.75% of NDF and 15.91% of ADF) and low metabolizable energy (2320kcal/kg). In the second assay, 60 male castrated piglets were used to evaluate the effect of inclusion on productive performance, diarrhea incidence and economic viability of parboiled rice bran. A randomized block design was used, with 5 treatments (0, 4, 8, 12 and 16%) and 6 replicates. There was no difference between treatments and control treatment as well as in regression analysis, and the increasing levels of parboiled rice bran did not reduce the performance of animals. In conclusion, parboiled rice bran can be included up to 16% in diets for piglets in the nursery phase.
