A total of 50 Sujiang pigs,weighing about 60 kg( there were no significant differences in the weight of the pigs),were selected. They were randomly and evenly divided into five groups: control group,A,B,C and D groups. The pigs in the control group were fed basal diet. For the pigs in the A,B,C and D groups,per kg of basal diet was added with 100,200,300 and 400 mg of compound plant extract,respectively. The experimental duration was 44 d. The results showed that in the treatment groups,the average daily weight gains were 15. 57%,20. 68%,17. 95% and 7. 31%,respectively higher than that of the control group,the feed-gain ratios were13. 29%,16. 92%,15. 11% and 11. 48%,respectively lower than that of the control group( P > 0. 05),and the economic benefits were62. 65,83. 23,72. 50 and 42. 11 yuan,respectively higher than that of the control group. In conclusion,the addition of compound plant extract in the basal diet of Sujiang pigs during fattening period can improve the economic benefit,and the economic benefit is best when the addition amount is 200 mg/kg.展开更多
【目的】比较苏姜猪背膘组织生长发育过程中基因表达谱的差异,挖掘影响背膘组织生长发育的关键基因。【方法】选择1、3、6和8月龄(M1、M3、M6、M8)4个生长时期苏姜猪背膘组织进行高通量转录组测序,组成3个比对组(M1 vs M3、M3 vs M6、M6...【目的】比较苏姜猪背膘组织生长发育过程中基因表达谱的差异,挖掘影响背膘组织生长发育的关键基因。【方法】选择1、3、6和8月龄(M1、M3、M6、M8)4个生长时期苏姜猪背膘组织进行高通量转录组测序,组成3个比对组(M1 vs M3、M3 vs M6、M6 vs M8)进行差异表达基因(differentially expressed genes,DEGs)的筛选,并进行功能富集和表达趋势分析。【结果】转录组测序显示,M1 vs M3、M3 vs M6、M6 vs M8组分别筛选到1869、296、1257个DEGs。功能富集显示,Wnt信号通路、细胞外基质-受体相互作用等信号通路在M1 vs M3组表现活跃,PI3K-Akt信号通路、AMPK信号通路、丁酸代谢、柠檬酸循环等信号通路在M6 vs M8组表现活跃。基因表达趋势分析显示,富含半胱氨酸的酸性分泌蛋白(secreted protein,acid and rich in cysteine,SPARC)、组织蛋白酶S(recombinant cathepsin S,CTSS)、Kruppel样因子7(Kruppel-like factor 7,KLF7)等基因与细胞增殖发育相关,在3月龄时高表达;胰岛素样生长因子-1受体(insulin-like growth factor 1 receptor,IGF1R)、信号转导与转录激活因子1(signal transducer and activator of transcription 1,STAT1)、脂肪酸合成酶(fatty acid synthase,FASN)等基因与细胞脂质代谢相关,在6月龄后表达显著上调。【结论】本研究获得苏姜猪4个生长时期背膘组织的基因表达谱,筛选到SPARC、CTSS、KLF 7等与细胞增殖发育相关的关键基因,IGF 1 R、STAT 1、FASN等与细胞脂质代谢相关的关键基因,为苏姜猪背膘厚的遗传改良提供了基础数据。展开更多
