The objective of the present study was to determine whether mango saponin (MS) could be used as a feed additive in broiler chicks by evaluating growth performance, carcass characteristics, meat quality, and plasma biochemical indices.
A total of 216 1-d-old Arbor Acres male broiler chicks were randomly assigned into three dietary treatments supplemented with 0 (control), 0.14% (MS 0.14%), or 0.28% (MS 0.28%) MS. Each treatment had six replicates (cages) with 12 chicks each. The feeding trial lasted for six weeks.
Compared with the control, dietary supplemented with 0.14% or 0.28% MS increased average daily weight gain of chicks in the grower (22 to 42 d) and the whole (1 to 42 d) phases, and the final body weight of chicks on d 42 was higher in MS supplemented groups (p<0.05). Lower L* (lightness) and L* values, lower b* (yellowness) value, and higher a* (redness) and a* values of the breast muscle were observed in chicks fed with 0.28% MS on d 42 (p<0.05). The total antioxidant capacity in plasma increased in MS 0.14% group on d 21 (p<0.001). Lower contents of plasma total cholesterol and triglyceride were observed in chicks fed with 0.28% MS on d 21 and d 42, whereas the group supplemented with 0.14% MS only decreased plasma triglyceride content on d 21 (p<0.05). The glucose content in plasma decreased in MS 0.28% group on d 42 (p<0.001).
Overall, MS could be used as a feed additive in broiler chicks, and the supplemental level of 0.28% MS in diet could improve growth performance, meat quality, and plasma lipid metabolism in broiler chicks.
本研究的目的是通过评估生长性能、胴体特征、肉质和血浆生化指标,确定芒果皂苷(MS)是否可作为肉鸡的饲料添加剂。
将216只1日龄的艾维茵雄性肉鸡随机分为三种日粮处理组,分别添加0(对照组)、0.14%(MS 0.14%)或0.28%(MS 0.28%)的MS。每个处理有六个重复(笼子),每个笼子有12只鸡。饲养试验持续六周。
与对照组相比,添加0.14%或0.28%MS的日粮增加了育成期(22至42日龄)和全期(1至42日龄)雏鸡的平均日增重,且在42日龄时,添加MS组的雏鸡终体重更高(p<0.05)。在42日龄时,饲喂0.28%MS的雏鸡胸肌的L*(亮度)值和L值较低,b(黄度)值较低,a*(红度)和a*值较高(p<0.05)。在21日龄时,0.14%MS组的血浆总抗氧化能力增加(p<0.001)。在21日龄和42日龄时,饲喂0.28%MS的雏鸡血浆总胆固醇和甘油三酯含量较低,而仅添加0.
