The Pradu Hang Dam chicken, a Thai Native Chicken (TNCs) breed, plays an important role in many regions of Thailand because of its chewiness. However, there are some challenges with Thai Native Chicken, such as low production and slow growth rates. Therefore, this research investigates the efficiency of cold plasma technology in enhancing the production and growth rates of TNCs. First, this paper presents the embryonic development and hatch of fertile (HoF) values of treated fertilized eggs. Chicken performance indices, such as feed intake, average daily gain (ADG), feed conversion ratio (FCR), and serum growth hormone measurement, were calculated to assess chicken development. Furthermore, the potential of cost reduction was evaluated by calculating return over feed cost (ROFC). Finally, the quality aspects of chicken breast meat, including color, pH value, weight loss, cooking loss, shear force, and texture profile analysis, were investigated to evaluate cold plasma technology's impact on chicken meat. The results demonstrated that the production rate of male Pradu Hang Dam chickens (53.20%) was higher than females (46.80%). Moreover, cold plasma technology did not significantly affect chicken meat quality. According to the average return over feed cost calculation, the livestock industry could reduce feeding costs by approximately 17.42% in male chickens. Therefore, cold plasma technology is beneficial to the poultry industry to improve production and growth rates and reduce costs while being safe and environmentally friendly.
普拉杜杭当鸡是一种泰国原生鸡（TNCs）品种，因其耐嚼而在泰国许多地区发挥着重要作用。然而，泰国原生鸡也存在一些挑战，例如产量低和生长速度慢。因此，这项研究调查了冷等离子体技术在提高 TNCs 产量和生长速度方面的效率。首先，本文介绍了经过处理的受精蛋的胚胎发育和孵化的 HoF 值。通过计算饲料摄入量、平均日增重（ADG）、饲料转化率（FCR）和血清生长激素测量等鸡的性能指标来评估鸡的发育情况。此外，通过计算饲料成本回报率（ROFC）评估了降低成本的潜力。最后，通过研究鸡肉胸脯肉的颜色、pH 值、失重、煮失率、剪切力和质地剖面分析等质量方面，评估了冷等离子体技术对鸡肉的影响。结果表明，普拉杜杭当公鸡的产仔率（53.20%）高于母鸡（46.80%）。此外，冷等离子体技术对鸡肉质量没有显著影响。根据平均饲料成本回报率的计算，畜牧业在公鸡方面可以降低约 17.42%的饲养成本。因此，冷等离子体技术有利于家禽业提高生产和生长速度，降低成本，同时安全环保。
