Physiological effects of polyphosphates with different chain lengths were unknown in poultry. The effect of 0.05% concentration of short chain polyphosphates (SCPP), medium chain polyphosphates (MCPP) and long chain polyphosphates (LCPP) was observed in broilers. MCPP and LCPP produced bacteriostatic properties against four pathogenic bacteria, , , serovar. Pullorum, and O157:H7. SCPP reduced the level of triglycerides in the blood. Intervention of MCPP and LCPP induced cecum IL-1β expression involved in the regulation of autoimmune inflammation. In terms of colony-forming units, SCPP increased the number of while MCPP and LCPP significantly decreasing the number of , and bacteria. SCPP, MCPP, and LCPP improved the intestinal microflora with abundance of beneficial bacteria such as , , and but with reduced . In addition, SCPP, MCPP, and LCPP did not adversely affect the meat quality of broilers. The antimicrobial properties of SCPP, MCPP, and LCPP can help to improve the intestinal environment and enhance immune properties. Based on the comparison of different length polyphosphates in broiler chickens, it is suggested that MCPP is more effective compared to SCPP and LCPP as antimicrobial feed additives.
不同链长的多聚磷酸盐对家禽的生理影响尚不清楚。观察了0.05%浓度的短链多聚磷酸盐（SCPP）、中链多聚磷酸盐（MCPP）和长链多聚磷酸盐（LCPP）对肉鸡的影响。MCPP和LCPP对四种病原菌，即鸡白痢沙门氏菌、鸡伤寒沙门氏菌、鸡副伤寒沙门氏菌和O157:H7具有抑菌特性。SCPP降低了血液中甘油三酯的水平。MCPP和LCPP的干预诱导了盲肠中参与自身免疫炎症调节的白细胞介素-1β表达。就菌落形成单位而言，SCPP增加了大肠杆菌的数量，而MCPP和LCPP显著减少了沙门氏菌、弯曲杆菌和产气荚膜梭菌的数量。SCPP、MCPP和LCPP改善了肠道微生物群，有益菌如双歧杆菌、乳酸菌和芽孢杆菌数量增加，但大肠杆菌数量减少。此外，SCPP、MCPP和LCPP对肉鸡的肉质没有不利影响。SCPP、MCPP和LCPP的抗菌特性有助于改善肠道环境并增强免疫特性。基于对肉鸡中不同长度多聚磷酸盐的比较，表明MCPP作为抗菌饲料添加剂比SCPP和LCPP更有效。
