Efficacy of zinc glycinate reducing zinc oxide on intestinal health and growth of nursery pigs challenged with F18+ Escherichia coli.

ABSTRACT: The objective of this study was to investigate effects of zinc glycinate (ZnGly) supplementation reducing zinc oxide (ZnO) in feeds on intestinal health and growth of nursery pigs challenged with F18+Escherichia coli (E. coli). In total, 72 nursery pigs (BW 6.5 ± 0.5 kg) were allotted in a randomized complete block design to nine treatments: (1) NC: no challenge/no supplement; (2) PC: E. coli challenge/no-supplement; (3) E. coli challenge/ZnO at 2,500 mg/kg; (4, 5, and 6) E. coli challenge/ZnGly at 400, 800, and 1,200 mg/kg; and (7, 8, and 9) E. coli challenge/ZnGly at 400 mg/kg and ZnO at 700, 1,400, and 2,357 mg/kg. Pigs were fed for 28 d based on two phases (phase 1: 14 d and phase 2: 14 d). On day 7, challenged groups were orally inoculated with F18+E. coli at 6 × 109 CFU/mL whereas NC
