Sustainable floor type for managing turkey production in a hot climate.

Floor type management is an important factor in turkey production in hot climates exceeding 30°C. In this study, a total of 360 turkeys aged 4 wk were randomly distributed to investigate growth performance, carcass characteristics, certain health aspects (breast blisters score, footpad burns, hock discoloration, and plumage condition), and airborne conditions. Birds in the first group were raised on a littered floor (control; C), whereas birds in the other groups (T1, T2, T3, T4, and T5) were raised on cement, wire net, rubber mat, plastic and wooden slatted floors, respectively. The results indicated that growth performance and meat quality were improved, with increases in body weight, daily body weight gain, feed conversion ratio, and tenderness and juiciness values, when plastic and wooden slatted floors were used. Moreover, the use of plastic and wooden slatted floors attenuated body temperature, airborne dust particulates, and ammonia concentrations. In conclusion, placing plastic, wooden slatted, or wire floors reduced the incidence of health disorders and alleviated heat stress effects by decreasing body temperature and the heterophil to lymphocyte ratio. Thus, plastic and wooden slatted floors are suitable for growing turkeys under the conditions of this study.
