Abstract

The current work aimed to evaluate the effect of feeding organic acids (OA) on growth performance, carcass traits, meat quality, blood parameters and immune response of broilers fed with a low protein diet (LPD). A total number of 68 broiler chicks (one-day-old) were randomly distributed into 4 equal groups each of 17 chicks. The first group was fed the basal diet (100% NRC crude protein (CP)) free from OA and considered as a control (T1). The other three groups (T2, T3 and T4) were fed on diets with different protein levels (95% NRC, 90% NRC & 85% NRC, respectively) and supplemented with OA at a level of 0.45%. The results showed that body weight and gain during starter phase (days 1-21) were not significantly (P = 0.7, P = 0.13, respectively) influenced by the supplementation of OA. However, during finisher phase (days 22-42) body weight and gain were significantly decreased (P < 0.05) in OA groups (-18% and -24%, respectively). A significant (P < 0.05) reduction in abdominal fat content and the meat cholesterol, triglyceride, and fat mass of broiler breast and thigh meat, while protein content significantly (P < 0.05) increased in all OA supplemented groups. In conclusion, adding OA improved immune response through increased serum globulin, and an increase in bursa relative weight of broilers. Moreover, the addition of OA to broiler fed LPD has no effect on growth parameters and carcass traits but improves broiler immunity and produces healthy meat to consumers.
日粮添加有机酸对低蛋白日粮肉鸡生长性能和免疫力的影响
本研究旨在评价有机酸(OA)对低蛋白日粮(LPD)肉鸡生长性能、胴体性状、肉质、血液参数和免疫反应的影响。将68只肉鸡(一日龄)随机分为4组,每组17只。第一组喂食不含OA的基础日粮(100%NRC粗蛋白(CP)),并被视为对照(T1)。其他三组(T2、T3和T4)分别饲喂不同蛋白质水平(分别为95%、90%和85%NRC)的日粮,并补充0.45%的OA。结果表明,补充OA对起始阶段(第1-21天)的体重和增重没有显著影响(分别为0.7和0.13)。然而,在完成阶段(第22-42天),OA组的体重和增重显著降低(P<0.05)(分别为-18%和-24%)。在所有补充OA的组中,肉鸡胸肉和大腿肉的腹部脂肪含量和肉胆固醇、甘油三酯和脂肪量显著降低(P<0.05),而蛋白质含量显著增加(P<0.05)。总之,添加OA通过增加血清球蛋白和增加肉鸡的法氏囊相对重量来改善免疫反应。此外,在饲喂LPD的肉鸡中添加OA对生长参数和胴体性状没有影响,但能提高肉鸡免疫力,为消费者生产健康的肉。
