Abstract

The present study aimed to investigate the effect of dietary pomegranate peel powder (PPP) and probiotic bacteria (PB) on the growth rate, carcass traits, blood serum metabolites, and meat quality of Ross broiler chickens during 1–5 weeks of age. A total of 480 unsexed Ross broiler chicks 7-days old with the beginning bodyweight of 110.58 ± 0.17 g were employed in a complete randomized purpose trail with eight groups; 60 chicks in six replicates (8 × 6 × 10). The dietary treatments were as follows: NC: negative group (without additives) group one; PC: positive control (main diet + 0.5 g Colostin antibiotic/kg feed); PPP 3–5: basal diet + 2, 3, 4 g pomegranate peel powder/kg diet and PPP 6–8: basal diet + 2, 3, 4 g pomegranate peel powder + 1 cm³ probiotic (Bacillus toyonensis (BT)/kg diet, respectively. The results showed that live body weight (LBW) at five weeks and body weight gain (BWG) during 1–5 weeks of age were affected by adding PPP in the ration and the good grads of PPP were 2 and 4 g PPP without PB/kg diet compared to NC and PC, respectively. Otherwise, daily feed conception (DFC) and feed conversion ratio (FCR) were not affected by adding the different grads of PPP with or without PB, except the first period of DFC (1–3 weeks of old) were affected. Results showed a significant effect on all carcass characteristics studied, except gizzard and abdominal fat ratio were not influenced by the treatment used. Likewise, the addition of PPP to broiler chicken diets has a good effect on almost the blood serum metabolites, immunological parameters and quality of meat studied. In the end, the outcome of this study concluded that the addition of PPP to broiler diets has a good effect on the growth rate, blood serum metabolites, immunological parameters and the quality of meat as well as the health aspects.

摘要

本研究旨在探讨日粮石榴皮粉 (PPP) 和益生菌 (PB) 对罗斯肉鸡 1-5 周龄生长速率、胴体性状、血清代谢物和肉质的影响。总共有 480 只 7 日龄的无性别罗斯肉鸡雏鸡，初始体重为 110.58 ± 0.17 克，用于八组的完整随机试验；60 只小鸡，6 次重复 (8 × 6 × 10)。饮食处理如下： NC：阴性组（无添加剂）第一组；PC：阳性对照（主要日粮 + 0.5 g Colostin 抗生素/kg 饲料）；PPP 3-5：基础日粮 + 2、3、4 g 石榴皮粉/kg 日粮和 PPP 6-8：基础日粮 + 2、3、4 g 石榴皮粉 + 1 cm ³益生菌（Bacillus toyonensis）(BT)/kg 饮食，分别。结果表明，在日粮中添加 PPP 会影响 5 周龄时的活体重 (LBW) 和 1-5 周龄期间的体重增加 (BWG)，且 PPP 的良好等级为 2 和 4 g PPP，不含 PB/ kg 饮食分别与 NC 和 PC 相比。否则，每日饲料受孕率 (DFC) 和饲料转化率 (FCR) 不受添加不同等级的 PPP 和 PB 的影响，除了 DFC 的第一阶段（1-3 周龄）受到影响。结果显示对所研究的所有胴体特征都有显着影响，除了胗和腹部脂肪比率不受所用处理的影响。同样，在肉鸡日粮中添加 PPP 几乎对所研究的血清代谢物、免疫学参数和肉质有很好的影响。到底，
