Application of response surface analysis to optimize the temperature-humidity relationship in broilers reared under commercial conditions
Keywords:
broiler, response surface analysis, temperature-humidity indexAbstract
The effects of changes in house temperature and relative humidity (RH) and their relationship on broiler production indicators in a commercial system with manual control of temperature and humidity were evaluated. Four production cycles were analyzed (26,000 birds/cycle; 10 broilers/m2). Each cycle consisted of four production phases (pre-starter, starter, grower and finisher). Feed and water were provided ad libitum. Six samples were taken from 120 birds per cycle in each phase, and body weight and daily weight gain were determined, as well as feed consumption and feed conversion ratio 1, phase 1 were estimated. The information was analyzed under fixed effects, principal components (PC) and response surface analysis (RSA) models. Temperatures and humidity were different (P<0.05) between cycles within each phase. Temperature and humidity affected (P<0.001) the productive indicators per cycle across phases. This was corroborated by the PC analysis (P<0.001). Meanwhile, the optimization process of the regression equations showed that the best combination of temperature and relative humidity was 29°C/31%, 26°C/35%, 25°C/35%, 30°C/44%, 14°C/64% y 18°C/50% and for weeks 1, 2, 3, 4, 5 y 6, respectively.
