摘要

本实验的目的是研究薄荷精油(PEO)和一种名为artifier的乳化剂对饲喂低能量日粮的肉鸡的生长性能、胴体特征和营养物质消化率的影响。将 240 只一天龄的雄性罗斯 308 肉鸡分为五个处理:对照组、低能量日粮、低能量日粮 + 150 ppm PEO、低能量日粮 + 300 ppm artifier 和低能量日粮 + 150 ppm PEO + 300 ppm artifier。每个处理重复四次,采用完全随机设计。鸡在开产期、生长期和育成期饲喂这些处理,共计 42 天。结果表明,与饲喂对照组日粮的肉鸡相比,饲喂添加了 PEO+ artifier 的低能量日粮的肉鸡的体重增加、饲料转化率和胸围百分比相似,但腹部脂肪百分比明显较低(P <0.05)。此外,与未添加任何添加剂的低能量日粮相比,在低能量日粮中单独或混合添加 PEO 和 artifier 的鸡在初生期和生长期表现出更高的干物质和脂肪消化率(P < 0.05)。在整个饲养期间,在低能量日粮中同时添加 150 ppm PEO 和 300 ppm artifier 的生长性能与对照日粮相当。此外,与对照日粮相比,在肉鸡低能量日粮中同时添加 PEO 和 artifier 可减少腹部脂肪,增加脂肪和干物质的消化率,提高营养利用率。

Effects of peppermint essential oil and artifier on growth performance, carcass characteristics and nutrient digestibilities in broiler chickens fed with low energy diets

The aim of this experiment was to investigate the effects of peppermint essential oil (PEO) and an emulsifier called artifier on growth performance, carcass characteristics, and nutrient digestibility of broiler chickens fed low-energy diets. A total of 240 one-day-old male Ross 308 broiler chickens were divided into five treatments: control, low-energy diet, low-energy diet + 150 ppm PEO, low-energy diet + 300 ppm artifier, and low-energy diet + 150 ppm PEO + 300 ppm artifier. Each treatment was replicated four times in a completely randomized design. The chickens were fed these treatments during the starter, grower, and finisher periods for a total of 42 days. The results indicated that broiler chickens receiving the low-energy diet supplemented with PEO + artifier had similar body weight gain, feed conversion ratio, and breast percentage, but exhibited significantly lower abdominal fat percentage compared to those fed the control diet (P < 0.05). Furthermore, birds receiving PEO and artifier in low-energy diets, either individually or in combination, demonstrated higher digestibility of dry matter and fat during the starter and grower periods in comparison to those receiving the low-energy diet without any additives (P < 0.05). Over the entire rearing period, the simultaneous inclusion of 150 ppm PEO and 300 ppm artifier in the low-energy diet resulted in comparable growth performance to the control diet. Additionally, the concurrent use of PEO and artifier in the low-energy diet for broiler chickens led to a decrease in abdominal fat, increased digestibility of fat and dry matter, and enhanced nutrient utilization compared to the control diet.
