Effects of Fruit By-product Extracts Supplementation on Growth Performance and Nutrient Digestibility in Growing Pigs

Abstract

ABSTRACT A total of 96 pigs [(Landrace × Yorkshire) × Duroc] with an initial BW of 27.94 ± 0.92 kg were used in a 6-week experiment to determine the effects of dietary supplementation with fruit by-product extracts on growth performance and nutrient digestibility in growing pigs. Pigs were randomly allotted to four treatments : 1) CON (basal diet), 2) PRO (CON + 0.5% procyanidin), 3) HES (CON + 0.5% hesperidin), 4) TAN (CON + 0.5% tannin). There were six replications per treatment with four pigs per pen. Supplementation had no effect ( p >0.05) on average daily gain, average daily feed intake, and G/F. The apparent total tract digestibility (ATTD) of dry matter and nitrogen was increased ( p <0.05) in the HES treatment relative to the PRO treatment. Pigs fed the HES and TAN diets had greater ( p <0.05) ATTD of energy than pigs fed PRO diet. The ATTD of ash was greatest( p <0.05) in HES treatments. In addition, the ATTD of calcium was greater ( p <0.05) in HES treatments than in CON and PRO treatments. Overall, the results of this study indicated that dietary supplementation with 0.5% fruit by-products did not affect growth performance, but inclusion of 0.5% hesperidin increased nutrient digestibility in growing pigs.(
