摘要

评估了日粮中添加非洲艾蒿精油对肉鸡肉质和脂肪酸分析的影响。取 400 只 Cobb500 日龄雏鸡,随机放入以下 4 种日粮中,重复 10 次:NC-阴性对照组(不含抗生素的肉鸡日粮)、PC-阳性对照组(添加杆菌肽锌的肉鸡日粮)、AA1-肉鸡日粮 + 0.1 % 阿夫拉精油和 AA2-肉鸡日粮 + 0.3 % 阿夫拉精油。每栏 10 只雏鸡为一个实验单位。从结果来看,除了拌料比例外,日粮对所有胴体性状都有影响(P < 0.01)。饲喂 AA1 日粮的雏鸡屠宰重(1846 克)和热胴体重(1427.36 克)最高。饲喂 AA1 日粮的禽类获得了最高的最终 pH 值(6.24),而饲喂 AA1 和 NC 日粮的禽类获得了最高的肉光度(L*)值(55.73 和 55.82)。饲喂 NC(31.01%)日粮的禽类烹饪损失最大。饲喂 AA2 日粮(23.7 毫克/克)的禽类肌肉内脂肪含量最高,其次是饲喂 AA1 日粮的禽类。日粮中添加 A. afra 精油还增加了 PUFA、n-6 和 n-3 脂肪酸的比例以及 PUFA/SFA 的比率。总之,在日粮中添加 A. afra 精油可改善肉鸡的肉质和脂肪酸组成,使消费者受益。

Artemisia afra essential oils inclusion in diets induces desirable effects on meat quality and fatty acid profiles of broilers chickens

The effects of Artemisia afra (African wormwood) essential oil incorporation in diets on meat quality and fatty acid profilers of broilers was assessed. Four hundred Cobb500 day-old chicks were obtained and placed randomly into the following 4 diets replicated 10 times: NC-Negative control (broiler diet without antibiotics), PC-positive control (broiler diet with zinc bacitracin), AA1-broiler diet + 0.1 % A. afra essential oil and AA2 - broiler diet + 0.3% A. afra essential oil. A pen having 10 chicks was regarded as the experimental unit. From the results, all carcass traits were influenced (P < 0.01) by diet apart from the dressing out percentage. The highest slaughter weights (1846g) and hot carcass weight (1427.36g) were obtained in birds fed the AA1 diet. Highest ultimate pH value (6.24) was obtained from the birds fed the AA1 while the highest values for meat lightness (L*) were obtained in birds offered the AA1 and NC diets (55.73 and 55.82). Cooking loss was highest in birds fed the NC (31.01%) diet. Birds fed the AA2 diet (23.7mg/g)) had the highest intramuscular fat followed by the AA1 fed birds. Inclusion of A. afra essential oils in diets also increased the proportion of PUFAs, n-6 and n-3 fatty acids and the PUFA/SFA ratios. In conclusion, the incorporation of A. afra essential oil in diets improved meat quality and fatty acid composition of broiler meat for the benefit of consumers.
