摘　　要： 试验旨在研究日粮中添加番茄渣对育肥猪生长性能、抗氧化性能和经济效益的影响。采用单因子试验设计,选择体重为(95.20±3.95)kg的杜洛克猪×长白猪×大白猪育肥母猪80头,随机分为4组,每组4个重复,每个重复5头猪:对照组喂基础日粮,Ⅰ、Ⅱ、Ⅲ组在基础日粮中分别添加100、200、300g/(头·d)番茄渣。试验期为37d。结果显示:与对照组比,Ⅰ组平均日增重和平均日采食量分别增加8.93%、18.81%(P<0.01),Ⅰ组料重比较对照组降低11.03%,其他组间差异不显著(P>0.05);Ⅱ组干物质和粗灰分表观消化率分别增加5.66%(P<0.05)、14.81%(P<0.01),Ⅱ、Ⅲ组粗纤维表观消化率极显著降低9.25%、11.88%(P<0.01),各组间粗蛋白质、粗脂肪表观消化率无显著差异(P>0.05);Ⅱ、Ⅲ组总超氧化物歧化酶(SOD)活性分别极显著增加了40.99%、36.54%(P<0.01),Ⅰ、Ⅱ、Ⅲ组丙二醛(MDA)含量均显著降低(P<0.05),各组血清总抗氧化能力(T-AOC)、谷胱甘肽(GSH)活性无显著差异(P>0.05);Ⅰ组增重收入586.26元/头,较对照组、Ⅱ组、Ⅲ组分别高48.06、52.20、52.92元;Ⅰ组利润最高,为466.90元。综上所述,添加番茄渣能够提高育肥猪生长性能、养分表观消化率、抗氧化性能及经济效益,但需控制用量。 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 5pigs per repeat.The pigs in control group were fed with basal diet,others in groupsⅠ,Ⅱ and Ⅲ were fed basal diet with 100,200 and 300g/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% and18.81%（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 groupⅡwere 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 groupsⅡ andⅢ were significantly increased by40.99% and 36.54%（P〈0.01）,respectively,and the MDA concent in groupsⅠ,ⅡandⅢ 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 586.26yuan/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（466.90yuan）.In conclusion,tomato pomace supplementation could improve growth performance,nutrient apparent digestibility,antioxidant capacity and the economic benefit,but the content should be controlled.
