A total of 96 pigs[(Landrace×Yorkshire)×Duroc] with an initial BW of 27.94±0.92kg 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.
Abstract
A total of 96 pigs[(Landrace×Yorkshire)×Duroc] with an initial BW of 27.94±0.92kg 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.
