Effects of dietary added Zn source and level on growth performance and mortality of HS broilers from 22 to 42 days of age. A ADFI. B ADG. C F/G. D Mortality. ZnS: Zn sulfate. Zn-Prot M: Zn proteinate with moderate chelation strength (Qf  = 51.6). NT: normal temperature, 23 ± 1 °C, 24 h/d. HT: high temperature, 9:00–17:00: 34 ± 1 °C, 8 h/d, and 17:00–9:00: 28 ± 1 °C. ADFI: average daily feed intake. ADG: average daily gain. F/G: feed to gain ratio. CON: control group. PF: pair-fed group, and the feed intake of PF birds was restricted to match that of those in the HT-CON group. Different letters indicate significant differences among treatments (P < 0.05). Data are mean ± SE (n = 5–7)
