Abstract	AbstractThis study was conducted to evaluate the effects of brown rice(Japonica) on growth performance, nutrient digestibility,and blood parameters of weanling pigs. A total of 60 weanling pigs (28-day-old,30 barrows and 30 gilts, 6.73 ± 0.77 kg body weight [BW]) were randomlyallotted to 2 dietary treatments (6 pigs per pen; 5 replicates per treatment) ina randomized complete block design with the initial BW and sex as blocks. Thedietary treatments were a typical nursery diet based on corn and soybean meal(CON) and the CON replaced 50% of corn with brown rice (BR). Pigs were fedrespective dietary treatments for 5 weeks. For the last week of experimentperiod, pigs were fed respective dietary treatments containing 0.2% chromicoxide as an indigestible marker. Fecal samples were collected from randomlyselected 1 pig in each pen daily for the last 3 d after the 4-d adjustmentperiod. Blood was collected from randomly selected 1 pig in each pen on d 0, 3,7, and 14 after weaning. Compared with pig fed CON diet, pigs fed the BR dietwere found to have higher (p < 0.05) final BW, overallaverage daily gain, and apparent ileal digestibility (AID) and apparent totaltract digestibility (ATTD) of dry matter and energy. However, there were nosignificant differences between the groups with respect to average daily feedintake, gain to feed ratio, frequency of diarrhea, and the AID and ATTD of crudeprotein during overall experimental period. Similarly, there were no significantdifferences on blood parameters between the groups. Thus, the findings of thisstudy indicate that brown rice (Japonica) can be used toreplace 50% of corn in the diet of pigs during the nursery period withoutnegatively affecting growth performance, nutrient digestibility, or bloodparameters.
