Change Regularity and Correlation Analysis of Hainan Special wild Boar Taint Substances
摘要
Abstract
[Objective] The aim of this study is to reveal the change regularity of boar taint substances by comparing differences in androstenone,skatole and indole in F1,F2,F3 different generations and boar taint substances effects on sex hormone levels to provide a theoretical basis for breeding of low-tying boar taint pigs.[Method] Eighteen individuals each of the different generations (boar ♂ × Tunchang pig ♀-) F1,F2,and F3 were used as the research objects.Then blood was collected and sera were extracted from the precaval vein of the experimental pigs,and then the fat and muscle samples were collected from the neck after slaughtering with standard method.ELISA kit and high performance liquid chromatography were used to detect and analyze the sex hormones,skatole and indole levels of each sample.The correlation and significance analysis of data were conducted by using SAS 9.0 software.[Result] The contents of skatole,androstenone and indole showed different correlation levels in different tissues.Skatole and androstenone contents of fat and muscle showed a significant positive relationship (P< 0.05 or P<0.01) with serum,and the maximum correlation coefficient of skatole in fat with that in serum was 0.94.Skatole,androstenone and indole contents of pork showed significant differences among different hybrid generations.With the increase of wild boar blood,androstenone levels were significantly increased,while the skatole levels were significantly reduced,but the indole showed no regularity in change.The sex hormone levels also had significant differences among different hybrid generations,the testosterone levels were significantly increased with wild boar blood,estradiol levels of F1 were significantly lower than that of F2 and F3.Skatole,androstenone and indole contents of fat,muscle and serum in different hybrid generations had different correlations with sex hormone levels,and androstenone of them had significant positive (P< 0.01) correlation with testosterone.Skatole had a significant negative (P<0.05 or P<0.01) correlation with testosterone.The maximum correlation coefficient between androstenone and testosterone in serum was 0.95.[Conclusion] With the increase of the content of the Hainan special wild boar blood,the testosterone levels increased significantly,the androstenone sedimentary volume increased significantly,and the skatole deposition quantity significantly reduced.So the changes of testosterone levels of Hainan special wild boar affect the contents of skatole and androstenone.关键词
