Purslane (Portulaca oleracea) was selected as the target plant for the present study due to its high nutritional value and antioxidant and antimicrobial properties. The aim was to investigate the effect of adding purslane powder on flock performance and immune response against Newcastle and infectious bursal disease. Purslane seeds were purchased from a medicinal company in India and, after preparation, used as a 1% powder. The experiment was conducted using 180 one-day-old Ross 308 broiler chickens, with the aim of investigating the effect of purslane powder on the performance and immunity system of the birds. The experiment was carried out in a completely randomized design, with three treatments, four replicates and 15 birds each. The experimental treatments comprised a negative control (basic feed without purslane powder or vaccination), a positive control (basic feed without purslane powder but vaccinated against Newcastle and infectious bursal disease virus (IBDV)), and a purslane group (basic feed with 1% purslane powder and vaccination). The results of the experiment demonstrated that performance indicators such as total weight at the end of the period, body weight gain, and European Production Efficiency Factor decreased with vaccination and increased significantly with the use of purslane powder in vaccinated chickens (p<0.05). Antibody titer against Newcastle disease virus in vaccinated chicks received purslane powder was more than vaccinated group without purslane, but the difference was not significant (p>0.05). The study also revealed that the antibody titer against the IBD vaccine increased in both vaccinated groups; however, the titer in the purslane group was significantly higher than in the group that received only vaccination (p<0.05). The findings of this study indicate that the supplementation of broiler feed with purslane can enhance the performance of broiler flocks, strengthen the immune response against ND and IBD vaccination, and positively impact the population of intestinal microflora.
马齿苋（Portulaca oleracea）因其高营养价值、抗氧化和抗菌特性而被选为当前研究的目标植物。目的是研究添加马齿苋粉对鸡群性能以及针对新城疫和传染性法氏囊病的免疫反应的影响。马齿苋种子从印度的一家医药公司购买，经过制备后用作1%的粉末。实验使用180只一日龄的罗斯308肉鸡进行，目的是研究马齿苋粉对鸡的性能和免疫系统的影响。实验采用完全随机设计，有三种处理方式，四个重复，每个重复15只鸡。实验处理包括一个阴性对照（不含马齿苋粉或未接种疫苗的基础饲料）、一个阳性对照（不含马齿苋粉但接种了新城疫和传染性法氏囊病病毒（IBDV）疫苗的基础饲料）以及一个马齿苋组（含1%马齿苋粉并接种疫苗的基础饲料）。实验结果表明，期末总重量、体重增加和欧洲生产效率因子等性能指标在接种疫苗后下降，而在接种疫苗的鸡中使用马齿苋粉后显著增加（p<0.05）。接种了马齿苋粉的雏鸡针对新城疫病毒的抗体滴度高于未接种马齿苋粉的接种组，但差异不显著（p>0.05）。该研究还表明，两个接种组针对IBD疫苗的抗体滴度均有所增加；然而，马齿苋组的滴度显著高于仅接种疫苗的组（p<0.05）。本研究结果表明，在肉鸡饲料中添加马齿苋可以提高肉鸡群的性能，增强针对ND和IBD疫苗接种的免疫反应，并对肠道微生物菌群数量产生积极影响。
