Natural antioxidants are crucial for preserving and enhancing the health, survival, reproduction, and reproductive function of poultry. Phycocyanin (PC) is a natural blue food colorant with various health benefits. The aim of this study was to extract phycocyanin (ApPC) from using simple and economical methods and investigate the impact of phytocyanin supplementation on the performance and fatty and amino acid profiles of broiler chicks.
PC was extracted from by freezing and thawing, and optimization conditions such as pH and temperature were applied during storage periods. A total of 270 1-week-old Ross breed broiler chicks were randomly assigned to the following three treatment groups: basal diet supplemented with 0 mg of PC/kg diet (control), basal diet supplemented with 1 g PC/kg diet (T1), and basal diet supplemented with 2 g PC/kg (T2). In a completely randomized design, three cage replicates (30 birds each) were assigned to each of the three groups. The dietary effects of ApPC on growth performance (body weight gain [BWG], body weight [BW], feed intake, feed conversion ratio, serum constituents, and antioxidant indices) in broiler chickens, free amino acids, and fatty acids in muscles were evaluated.
Total BWG and BW increased without a significant effect on the total feed consumption. Serum levels of total proteins and albumin increased with increasing ApPC supplementation. In addition, globulin levels significantly increased. There was a significant decrease in serum total cholesterol levels among the treatments. The activity of antioxidant enzymes (superoxide dismutase, catalase, glutathione, and total antioxidant capacity) is significantly increased. In contrast, an increase in ApPC caused a significant decrease in malondialdehyde. The content and quantity of fatty acids and amino acids in the meat of broiler chicks supplemented with PC varies.
The addition of PC to broiler chicken diets enhances antioxidant activities, BW, BWG, and meets quality requirements.
天然抗氧化剂对于维持和提高家禽的健康、生存、繁殖及生殖功能至关重要。藻蓝蛋白（PC）是一种具有多种健康益处的天然蓝色食用色素。本研究的目的是采用简单经济的方法从[具体来源未给出]中提取藻蓝蛋白（ApPC），并研究补充藻蓝蛋白对肉鸡生长性能、脂肪酸和氨基酸谱的影响。
通过冻融法从[具体来源未给出]中提取PC，并在储存期间应用pH和温度等优化条件。总共270只1周龄的罗斯品种肉鸡随机分为以下三个处理组：基础日粮添加0毫克PC/千克日粮（对照组）、基础日粮添加1克PC/千克日粮（T1）和基础日粮添加2克PC/千克（T2）。在完全随机设计中，将三个笼重复（每组30只鸡）分配给三组中的每一组。评估了ApPC对肉鸡生长性能（体重增加[BWG]、体重[BW]、采食量、饲料转化率、血清成分和抗氧化指标）、肌肉中游离氨基酸和脂肪酸的日粮影响。
总BWG和BW增加，对总采食量无显著影响。随着ApPC添加量的增加，血清总蛋白和白蛋白水平升高。此外，球蛋白水平显著升高。各处理间血清总胆固醇水平显著降低。抗氧化酶（超氧化物歧化酶、过氧化氢酶、谷胱甘肽和总抗氧化能力）的活性显著增加。相反，ApPC的增加导致丙二醛显著降低。补充PC的肉鸡肌肉中脂肪酸和氨基酸的含量及数量各不相同。
在肉鸡日粮中添加PC可增强抗氧化活性、BW、BWG，并满足质量要求。
