White rice and parboiled rice were utilized as a replacement for corn in a corn-soybean diet and provided to broilers from day 1 to 7 or day 1 to 21 (Ebling et al., 2015). In the pre-starter (day 1β7) and starter feed (day 8β21), white rice or parboiled rice represented ~50% of the feed, depending on the trial.
Density was nearly constant at 1.452 g/ml in all rice varieties; in paddy, the value was around 1.182 g/ml for round varieties and around 1.224 g/ml for others. Bulk density varied appreciably in both rice (0.777β0.847) and paddy (0.563β0.642 g/ml), and so did porosity (41β46% in rice, 46β54% in paddy). yROUCZB.
