Abstract:
This study examined the influence of early atmospheric ammonia exposure, light intensity throughout rearing, and their interaction on blood gases, electrolytes, and acid-base balance in broiler chickens under environmentally controlled conditions. The experiment consisted of a 3 x 3 factorial arranged in a randomized complete block design, with trials being replicated over time. The 9 treatments consisted of 3 levels (0, 25, and 50 ppm) of ammonia concentrations for 14 d and levels (0.2, 2.0, and 20 lx) of light intensities from 8 to 36 d of age. Venous blood samples were collected on d 6, 11, 14, and 35. On d 6, partial pressure of CO2 and Na+ increased significantly (P
