    Abstract:
    Foot pad dermatitis (FPD) is a very common disease affecting poultry and is mostly caused by bad litter condition. This study aimed to test the effects of poultry diets with normal levels of electrolytes compared with a surplus level of electrolytes with and without using floor heating. Eighty two-week-old ♀ turkey poults were reared over 3 weeks on wood shavings, divided randomly into four groups. Two groups were fed normal levels of electrolytes (1.60 g Na; 7.80 g K/kg diet), and the other two groups were fed surplus levels of electrolytes (3.10; 15.3 g/kg diet). In each dietary treatment, half of the birds were exposed to floor heating. Half of the birds in each group were exposed for 4 h/day to wet litter (35% water) in adjacent separate boxes. External assessment of foot pads was performed weekly. High dietary electrolytes increased the severity of FPD significantly (3.65 ± 1.03). Floor heating is likely to be highly effective in significantly reducing the severity of FPD (2.36 ± 0.588). Despite forced water intake, the litter became drier when floor heating was in use. Combining low Na and K levels with a floor heating system reduced the scores of FPD by approximately 60%, compared with high electrolyte levels without floor heating. Therefore, both dietary electrolyte levels and floor heating markedly affected FPD via litter moisture.
