Effects of extracted rice bran supplementation on growth performance, nutrient digestibility, diarrhea score, blood profiles, and fecal microbial shedding in comparison with apramycin (antibiotic growth promoter) in weanling pigs

다국어 초록 (Multilingual Abstract)

<P> This study evaluated the efficacy of extracted rice bran (ERB) in weanling piglets. One hundred forty weanling pigs [(Yorkshire × Landrace) × Duroc] with an average BW of 5.70 ± 1.41 kg (21 d of age) were fed in two phases in a 6-wk experiment. Weanling pigs were allotted to diets containing 0 or 0.1 g kg<SUP>−1</SUP> of ERB, and 0 or 165 mg kg<SUP>−1</SUP> of apramycin according to a 2 × 2 factorial arrangement of treatments. Both apramycin and ERB supplementation increased growth efficiency (G:F) during phase 1 and overall, respectively (P @@<@@ 0.05). The apparent total tract digestibility (ATTD) of dry matter (DM) was increased in response to either ERB or apramycin at wk 2 and 6 (P @@<@@ 0.05). Supplementation of ERB decreased total cholesterol (TC) and increased high-density lipoprotein cholesterol (HDL-C) in diets lacking ERB at wk 6 (P @@<@@ 0.05). Pigs receiving diets supplemented with apramycin reduced Escherichia coli at wk 2 and 6, and Salmonella counts at wk 6 (P @@<@@ 0.05). Supplementation of ERB increased fecal Lactobacillus and reduced Salmonella counts at wk 6 (P @@<@@ 0.05). In conclusion, results indicated that dietary supplementation of ERB improved performance in weanling pigs. </P>
