Effect of Dietary Grape Pomace Fermented by Saccharomyces boulardii on the Growth Performance, Nutrient Digestibility and Meat Quality in Finishing Pigs
L. Yan, I. H. Kim
Fifty-six [(DurocYorkshire)Landrace] pigs with an average initial BW of 19.30.17 kg were used in this 15-wk growth experiment to investigate the effects of grape pomace fermented by Saccharomyces boulardii on pig growth performance, nutrient digestibility and quality attributes of pork. Pigs were allotted to 2 dietary treatments (7 replications) based on their initial BW in a randomized complete block design. The experimental treatments were: i) control (CON; basal diet), ii) FGPP (CON+30 g/kg fermented grape pomace product). Dietary FGPP improved (p<0.05) average daily gain (ADG), coefficient apparent total tract digestibility (CATTD) of dry matter (DM) and nitrogen (N) during 35-70 d of the experiment. Similarly, pigs fed the FGPP supplemented diet had a higher N digestibility (p<0.05) in the finisher phase (day 71-105). Dietary FGPP increased (p<0.05) the marbling score, the redness (a*) and yellowness (b*) values, as well as the anti-oxidative ability (lower TBARS). The inclusion of FGPP reduced palmitic acid (C:16:0), stearic acid (C:18:0), arachidic acid (C:20:0) and SFA levels (p<0.05) in subcutaneous fat. An increased (p<0.05) linoleic acid (C18:2n6), total PUFA and PUFA/SFA ratio were observed in the FGPP group. Dietary FGPP supplementation decreased the arachidic acid (C:20:0) level in longissimus muscle (LM). In conclusion, dietary inclusion of FGPP at the level of 30 g/kg improved the growth performance, nutrients digestibility and altered the fatty acid pattern in the subcutaneous fat as well as some attributes of pork meat.
