Performance of growing swines fed with a diet containing rice subproducts

Objective. To evaluate the performance of swines fed with rice sub products during the growing fase. Materials and methods. Forty hybrid piglets of 31.26 ± 4.62 kg, were allotted to 5 groups an experimental randomized block design: 1. Control diet; 2. Diet plus 100% replacement of corn by broken rice; 3. Diet plus 50% replacement of corn by broken rice; 4. Diet plus 100% replacement of corn by whole bran rice; 5. Diet plus 50% replacement of corn by whole bran rice. Results. Poor performance was found in all phases evaluated (I, II and total phase) in swines fed with diets containing whole bran rice. More, evident negative effects were found when corn was completely replaced for bran rice (intake food 1.467 kg and 0.512 kg of weight gain). Replacement of corn for broken rice not affect performance (intake food 1.681 and 1.733 kg and 0.703 and 0.708 kg weight gain respectively). The poorest fed conversion (2.87) was found when corn was completely replaced by whole bran rice. Conclusions. The corn can be replaced by 100% of broken rice or by 50% of whole bran rice without affect the performance of the swine during the growing phase.
