摘要/Abstract

摘要： 试验旨在探究野乔菜替代部分基础日粮对从江香猪肌肉脂肪酸和氨基酸的影响。选取体重约20 kg的从江香猪40头,随机分为4个组,每组10头。对照组饲喂基础日粮,试验前期试验Ⅰ、Ⅱ、Ⅲ组分别以野乔菜替代10%、20%和30%的基础日粮,试验后期分别用野乔菜替代20%、30%和40%的基础日粮。育肥期结束后,每组随机抽取3头屠宰,取背最长肌用于脂肪酸和氨基酸测定。结果显示:①野乔菜替代不同比例基础日粮对从江香猪肌肉脂肪酸含量有一定影响。与对照组相比,试验Ⅰ组亚油酸、试验Ⅰ、Ⅱ组亚麻酸、试验Ⅱ组花生二烯酸和试验Ⅰ组花生四烯酸分别提高了54.69%、43.57%、62.50%、25.00%和127.10%;各试验组中,饱和脂肪酸(SFA)、多不饱和脂肪酸(PUFA)及必需脂肪酸(EFA)总含量均高于对照组(P>0.05)。②野乔菜替代部分基础日粮对氨基酸含量有一定影响。对照组天门冬氨酸显著低于试验Ⅰ(P<0.05)、极显著低于Ⅲ组(P<0.01);试验Ⅲ组甘氨酸显著高于试验Ⅰ、Ⅱ组(P<0.05),且高于对照组(P>0.05),甲硫氨酸、赖氨酸含量分别显著高于对照组(P<0.05)和试验Ⅰ组(P<0.05);试验Ⅰ组EAA/TAA显著低于其他3组(P<0.05)。综上所述,野乔菜替代部分基础日粮能在一定程度上提高从江香猪肌肉PUFA和EFA含量,显著提高了部分氨基酸含量。

Abstract: This study investigated the effects of replacing partial basal diet with wild buckwheat on fatty acids and amino acids in longissimus dorsi muscles of Congjiang Xiang pigs.Forty Congjiang Xiang pigs with 20 kg initial body weight,were randomly assigned to 4 groups,10 heads per group.The pigs in control group were fed the basal diet.In the other groups (groupⅠ,Ⅱ and Ⅲ),diets were substituted with fresh wild buckwheat at 10%,20% and 30% on the early fattening stage and 20%,30% and 40% on the late fattening stage,respectively.After feeding trial,three pigs from each dietary treatment were slaughtered to determine the fatty acids and amino acids in longissimus dorsi muscle.The results showed that:①The partial substitution of basal diet with wild buckwheat had some effects on fatty acids in porcine muscle.Compared with the control group,the content of linoleic acid in the group Ⅰ,the content of linolenic acid in group Ⅰ and Ⅱ,the content of peanut diene acid of group Ⅱ and arachidonic acid of group Ⅲ were increased by 54.69%,43.57%,62.50%,25.00% and 127.10%,respectively.The saturated fatty acid (SFA),polyunsaturated fatty acid (PUFA)and essential fatty acid (EFA)of all testing groups were higher than that of control group (P>0.05).②The amino acids were affected in some degree by the substitution rate of wild buckwheat.The content of asparaginic acid in control group was significant lower than that in group Ⅰ(P<0.05) and extremely significant lower than that of group Ⅲ (P<0.01).The content of glycine in group Ⅲ was significantly higher than that of groupⅠ and Ⅱ (P<0.05),higher than that of control group (P>0.05).The content of methionine and lysine in group Ⅲ were significantly higher than that in control group and group Ⅰ (P<0.05),respectively.The EAA/TAA in group Ⅰ was significantly lower than the other groups(P<0.05).In conclusion,partial substitution of basal diet with wild buckwheat could increase the contents of PUFA and EFA,and improve the amino acid profile of Congjiang Xiang pigs.

Key words: Congjiang Xiang pigs; wild buckwheat; different substitution ratios; fatty acid; amino acid
