Abstract:

This study was aimed to study the effects of tomato pomace on growth performance,antioxidant capacity and economic benefit of finishing pigs.80 Doroc pig×Landrace pig×Yorkshire pig crossbreeding finishing pigs with (95.20±3.95) kg body weight were chosen and divided into four groups with four repeats per groups and 5 pigs per repeat. The pigs in control group were fed with basal diet,others in groups Ⅰ,Ⅱ and Ⅲ were fed basal diet with 100,200 and 300 g/d tomato pomace supplementation,respectively. The test lasted for 37 d.The results showed that compared with control group,the ADG and ADFI of group Ⅰ were increased by 8.93% and 18.81%(P<0.01),respectively,while the F/G of group Ⅰ was decreased by 11.03% than control group (P<0.05).The nutrient apparent digestibility of dry matter and crude ash in groupⅡ were increased by 5.66% (P<0.05) and 14.81% (P<0.01),respectively. The crude fiber apparent digestibility of groups Ⅱand Ⅲ were significantly reduced by 9.25% and 11.88% (P<0.01),while the digestibility of crude protein and crude fat had no significant difference among the four groups (P>0.05).The SOD activity of groups Ⅱ and Ⅲ were significantly increased by 40.99% and 36.54% (P<0.01),respectively,and the MDA concent in groups Ⅰ,Ⅱ and Ⅲ were significantly decreased (P<0.05), while the serum T-AOC and GSH activity had no significant difference among the four groups (P>0.05).The weight gain income of group Ⅰ was 586.26 yuan/head,increased by 48.06,52.20 and 52.92 yuan than control group,groups Ⅰ and Ⅱ,respectively. The profit of groupⅠ was the highest (466.90 yuan).In conclusion,tomato pomace supplementation could improve growth performance,nutrient apparent digestibility,antioxidant capacity and the economic benefit,but the content should be controlled.

Key words: tomato pomace; growth performance; nutrient apparent digestibility; antioxidant capacity; economic benefits
