PRADO-REBOLLEDO, Omar et al. Effect of incubator carbon dioxide level on embryonic development and hatching parameters in broiler chicken. Abanico vet [online]. 2020, vol.10, e122.  Epub 07-Mayo-2021. ISSN 2448-6132.  https://doi.org/10.21929/abavet2020.39.

Oxygen (O 2) and carbon dioxide (CO 2) are vital gases for the embryo during the incubation process, its level is essential at pipping, to evaluate the effect of incubator carbon dioxide level on embryonic development, hatching parameters, and post-hatch growth of broiler, humidity loss, hatchability, weight of chicken, size of chicken, blood glucose, hematocrit and plasma proteins were measured. A total of 600 eggs from commercial breeding Cobb 500 41 weeks, were selected by weight from 65 to 70 g, were distributed on two incubators. A machine was kept at 4000 ppm and the other to 3000 ppm CO2. A 2 x 2 factorial design was used. The hatchability was better to 3000 ppm of CO2 and egg weight of 65 g chicken egg; the chicken was heavier with eggs of 70 g, to more ppm of CO2 reduction in the loss of humidity, was observed over a large chicken, blood glucose levels were not affected, but the values of plasma protein were less than 3000 ppm CO2. Improved hatching parameters at lower ppm of CO2 during the incubation process.
