Enhancing the sustainability of chicken farming involves improving health and productivity and product qualities. This study explores the influence of (SP) supplementation on the productivity, egg quality, shelf life during storage, and blood biochemistry of laying hens. A total of 192 thirty-nine-week-old White Leghorn hens were randomly divided into 4 dietary groups: a control group and 3 treatment groups receiving 2.5 g/kg, 5 g/kg, or 10 g/kg of SP, respectively. The study was conducted for six weeks with measuring feed intake, feed conversion ratio, egg production, egg quality, shelf life, and blood biochemistry. The results demonstrated significant enhancements in egg weight ( < 0.05) and egg mass ( < 0.05) in the treatment of SP groups. The SP treated hens showed significant improvements in yolk color ( < 0.05) and Haugh unit scores ( < 0.05). The SP supplementation showed a hepatoprotective effect, as indicated by significant reduction in Alanine aminotransferase (ALT) ( < 0.05) and alkaline phosphatase (ALP) ( < 0.05) levels; however, increases in total protein, albumin, and globulin levels were observed. Furthermore, the egg quality of stored eggs for 21 days linearly increased with increments in the SP levels. In conclusion, it can be speculated that adding SP at 2.5 g/kg and 5 g/kg can significantly improve the productivity of laying hens, eggs' quality, shelf life, and blood biochemistry, thereby contributing to a more sustainable and efficient chicken production.
提高养鸡业的可持续性涉及改善鸡的健康状况、生产性能和产品质量。本研究探讨了补充（某种物质，原文未明确写出全称，推测为SP）对蛋鸡生产性能、蛋品质、储存期货架期以及血液生化指标的影响。总共192只39周龄的白来航蛋鸡被随机分为4个日粮组：一个对照组和3个处理组，分别接受2.5克/千克、5克/千克或10克/千克的（某种物质，推测为SP）。该研究持续了六周，期间测量了采食量、饲料转化率、产蛋量、蛋品质、货架期和血液生化指标。结果表明，在（某种物质，推测为SP）处理组中，蛋重（P<0.05）和产蛋量（P<0.05）有显著提高。经（某种物质，推测为SP）处理的母鸡的蛋黄颜色（P<0.05）和哈夫单位评分（P<0.05）有显著改善。补充（某种物质，推测为SP）显示出肝脏保护作用，丙氨酸转氨酶（ALT）（P<0.05）和碱性磷酸酶（ALP）（P<0.05）水平显著降低；然而，观察到总蛋白、白蛋白和球蛋白水平有所增加。此外，随着（某种物质，推测为SP）水平的增加，储存21天的鸡蛋的蛋品质呈线性增加。总之，可以推测，添加2.5克/千克和5克/千克的（某种物质，推测为SP）可以显著提高蛋鸡的生产性能、蛋品质、货架期和血液生化指标，从而有助于实现更可持续和高效的养鸡生产。
