Abstract The present study was aimed at investigating the effects of the dietary use of different doses of Moringa oleifera essential oil (MOEO) on performance parameters, internal organ weights and meat quality in Japanese quails (Coturnix coturnix japonica) exposed to Heat Stress (HS). For this purpose, 320 male day-old quail chicks were used. Seven days of preliminary (physical exercise) and a 35-day fattening period were applied. The animals were divided into 8 groups, each including 40 animals according to temparature (C: 25 °C and SC: 37 °C) and dietary doses (C, 200, 400 and 600). Each group was divided into 4 subgroups, each comprising 10 animals. The consequences of this study showed that, in the stress-free (HSF) groups, while all of the different doses of dietary MOEO positively affected growth performance, feed intake and feed efficiency, in the HS groups, similar positive effects were observed with the use of 200 ppm of dietary MOEO. While no effect was detected on internal organ weights on Days 21 and 42 in the HSF and HS groups, a dose-dependent increase was determined in the intestinal pH value on day 42 in the HS group (p < .05). Additionally, in the analysis of meat quality on the 21st and 42 days compared to the controls, no effect was observed on the meat colour parameters value and TBARS level in the HS and HSF groups. Based on the consequences of this study, it is considered that, MOEO could be used as an alternative product in poultry, at a dose of 200 ppm, to reduce the detrimental effects of HS. HIGHLIGHTS Temperature stress, performance parameters and serious problems in the health of poultry. Moringa olifera helps regulate performance parameters in poultry exposed to heat stress. Since the addition of Moringa oleifera to the diets does not affect the organ weight and meat quality in 21 and 42 days, it does not cause any negative effects for the consumer.

日本鹌鹑(Coturnix coturnix japonica)在热应激条件下对日粮添加辣木精油的反应

摘要 本研究旨在研究日粮中使用不同剂量的辣木精油 (MOEO) 对暴露于热应激 (HS) 的日本鹌鹑 (Coturnix coturnix japonica) 的性能参数、内脏重量和肉质的影响。 . 为此,使用了 320 只雄性日龄鹌鹑雏鸡。应用了 7 天的初步(体育锻炼)和 35 天的育肥期。根据温度(C:25°C 和 SC:37°C)和饮食剂量(C、200、400 和 600),将动物分为 8 组,每组包括 40 只动物。每组分为4个亚组,每个亚组包括10只动物。这项研究的结果表明,在无压力 (HSF) 组中,虽然所有不同剂量的膳食 MOEO 都对生长性能产生了积极影响,饲料摄入量和饲料效率,在 HS 组中,使用 200 ppm 的日粮 MOEO 观察到类似的积极影响。虽然在第 21 天和第 42 天在 HSF 和 HS 组中未检测到对内脏器官重量的影响,但在第 42 天在 HS 组中确定了肠道 pH 值的剂量依赖性增加(p < .05)。此外,与对照组相比,在第 21 天和 42 天的肉质分析中,未观察到对 HS 和 HSF 组的肉色参数值和 TBARS 水平产生影响。根据这项研究的结果,可以认为 MOEO 可以用作家禽的替代产品,剂量为 200 ppm,以减少 H2S 的有害影响。亮点 温度压力、性能参数和家禽健康方面的严重问题。辣木有助于调节暴露于热应激的家禽的性能参数。由于在饮食中添加辣木不会影响 21 天和 42 天的器官重量和肉质,因此不会对消费者造成任何负面影响。
