Por el Fenómeno El Niño, altas temperaturas y pocas lluvias serán constantes climáticas en los próximos meses. ¿Cómo prepararse para prevenir estrés en las aves?
Por estar cubiertos de plumas, pollos y gallinas eliminan su calor corporal por sus superficies descubiertas, como crestas y barbillas, o a través del jadeo (aspirar aire fresco y exhalar aire caliente). Tampoco tienen glándulas sudoríparas, lo cual les hace muy vulnerables al exceso de calor. Sin comodidad térmica, consumen más agua (si esta no está caliente) o se dedican a jadear y no se alimentan normalmente, lo que dificulta una conversión eficiente de grano en carne o huevo.
