Relative abundance and differential correlation of gut microbiota in broilers fed two zinc sources and exogenous phytase
The addition of zinc (Zn) in the form of zinc oxide (ZnO) and zinc sulfate (ZnSO4) as a supplement is a conventional practice to meet broilers' nutritional Zn requirements. Depending on the source and amount, Zn has been shown in vitro to affect the efficiency of exogenous phytase, an enzyme used to increase phytate degradation in broilers. Little is known about the impact of Zn on the gut microbiota of broilers. This work aimed to investigate whether supplemental Zn, varying by Zn source and Zn level, and the dietary inclusion of phytase influence the composition of the microbiota in the feedstuffs, ileum, and litter.
