| Outline of Final Research Achievements |
Short-chain fatty acids (SCFA) are produced in hindgut, and utilized as a metabolic energy in host animals. The energy contribution of SCFA to the basal metabolic rate is 30-76 % in pigs. The main feedstuff of “corn” is very expensive in Japan, partially modification to a fermentable by-product (FBP) may be beneficial in swine industry. Therefore, we selected FBP, and the large supply of FBP improved the growth performance of growing pigs through stimulation of hindgut fermentation. We selected the “rapeseed meal(Rm)” and “beet-pulp(Bp)” as FBP by in vitro screening. Rm 5% supplemented diet improved the daily gain and feed conversion ratio compared by Bp supplemented or control diet. The hindgut fermentation was stimulated by Rm supplemented diet, and the utilization of SCFA by the host animals was inclined according to consideration by aroterio-veneous difference. Therefore, partially modification from corn to Rm, as a FBP, is beneficial for growth performance in growing pigs.
