Abstract

Despite the fact that the use of rosemary and thyme residues and essential oils in animal feeding was widely documented, that of myrtle is scarce. To test the hypothesis that myrtle essential oils (MEOs) could improve goats' carcass characteristics and meat quality traits, twenty-one male goats received a ration consisted of 40% oat hay and 60% concentrate. Experimental goat kids received the control diet supplemented with 0, 0.3 and 0.6% of myrtle essential oils (MEOs) for C, Myrt1 and Myrt2 groups respectively. The administration of MEO did not improve the daily DM intake (p > 0.05). Kids of C and Myrt2 groups had higher average daily gain than Myrt1 group (75 versus 55 g). The goats slaughtered at 19.9 kg of weight did not differ (p > 0.05) in carcass weights and carcass yield in terms of commercial dressing percentage (CDP = 41%) and real dressing percentage (RDP = 52%). The administration of MEO increased the meat polyphenol content, being higher in both Myrtle groups (87 versus. 56 μg gallic acid equivalents g fresh matter, p < 0.05). Myrtle EO administration protected kids' meat against oxidation (0.48 versus. 0.91 mg MDA/kg of meat for Myrtle and C groups, respectively, at the 9th day of storage; p < 0.05). It could be useful to include MEO as a dietary supplement in goats' rations since it improves meat's oxidative status without negative effects on FA profile.

摘要

尽管迷迭香和百里香残渣和精油在动物饲养中的应用有广泛的记载,但桃金娘的应用却很少。为了验证桃金娘精油(MEOs)可以改善山羊胴体特征和肉质特性的假设,21 只雄性山羊接受了由 40%燕麦干草和 60%浓缩饲料组成的日粮。实验组山羊接受对照饮食,分别用 0、0.3 和 0.6%的桃金娘精油(MEO)补充 C、Myrt1 和 Myrt2 组。MEO 的添加并没有提高每日 DM 摄入量(p>0.05)。C 和 Myrt2 组的羔羊比 Myrt1 组的平均日增重更高(75 比 55g)。在体重为 19.9kg 时,屠宰的山羊在胴体重和胴体产肉率方面没有差异(以商业屠宰率(CDP=41%)和实际屠宰率(RDP=52%)表示)。MEO 的添加增加了肉中的多酚含量,在两个桃金娘组中更高(87 比 56μg 没食子酸当量/g 鲜重,p<0.05)。MEO 的添加保护了羔羊的肉免受氧化(在第 9 天的贮藏期,Myrtle 和 C 组的肉中的 MDA 含量分别为 0.48 和 0.91mg/kg,p<0.05)。在山羊的日粮中添加 MEO 作为膳食补充剂可能是有用的,因为它可以改善肉的氧化状态,而不会对 FA 谱产生负面影响。
