The focus of this study is to evaluate if tobacco seed cake, administered in feed, can affect principal serum metabolic parameters of weaned piglets in order to establish if it can be used as both a delivery system of edible vaccines and an alternative protein source in piglets diet. A total of 48 weaned piglets were divided in two homogeneous groups for weight, control (CG) and treatment (TG);TG and CG were fed ad libitum with two isoenergetic and isoproteic experimental diets (CP: 17.68% CG and 17.64% TG) differentiated for the inclusion of 4% of tobacco seed cake in the TG diet in replacement of wheat bran and soybean meal. Growth performances were evaluated and feed intake was measured weekly. Blood samples were collected on days 0, 20 and 43 to evaluate hematocrit and principal metabolic parameters, in order to assess the health status of the animals. The administration of tobacco did not impaire health status and growth performance of piglets. The use of bioenergy co-products from non-food crops may represent a good approach creating an integration between biofuel and food production, with consequent benefits for food security and environmental impact.展开更多
为探究烟草种子萌发过程对低温胁迫的响应,对萌发1 d、2 d和3 d的种子分别进行2 d低温处理(LT1、LT2和LT3),分析不同萌发时期种子遇到低温的蛋白与多肽变化,分别以萌发2 d、3 d和4 d的种子为对照(GS2、GS3和GS4),形成3个组合GS2 vs LT1...为探究烟草种子萌发过程对低温胁迫的响应,对萌发1 d、2 d和3 d的种子分别进行2 d低温处理(LT1、LT2和LT3),分析不同萌发时期种子遇到低温的蛋白与多肽变化,分别以萌发2 d、3 d和4 d的种子为对照(GS2、GS3和GS4),形成3个组合GS2 vs LT1、GS3 vs LT2和GS4 vs LT3。结果显示,GS2 vs LT1、GS3 vs LT2和GS4 vs LT3的差异多肽集合的交集共计20个多肽,GO和KEGG富集分析发现3个组合的差异蛋白均与碳代谢、氨基酸生物合成相关;此外鉴定到8个参与到低温应答的多肽,其中Nitab4.5_0002257g0090多肽在3个组合中同时被鉴定到,可能在低温应答过程中存在重要的功能。本研究为后续挖掘多肽在低温应答过程的功能提供了研究基础。展开更多
