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、300 g/(头·d)番茄渣。试验期为37 d。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。

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
