Four experiments involving CO2 level in single-stage incubators were conducted at a commercial turkey hatchery. Carbon dioxide was injected into incubators to a level of .3% during the first 10 days of incubation. Noninjected control incubators were maintained at a .1% CO2. Eggs from the injected incubators had a higher hatchability and lower early, late, and malpositioned embryonic mortality. No difference in hatchability was found between .3 and .5% CO2 concentrations for the first 10 days of incubation. Carbon dioxide injection for the first 5 days of incubation decreased hatchability when compared to CO2 injection for the first 10 days. Carbon dioxide injection for the first 14 days of incubation resulted in no difference in hatchability from injection for the first 10 days. The artificial addition of CO2 to single-stage turkey incubation systems may be of economic importance in commercial hatcheries because of its effect on hatchability.
在一家商业火鸡孵化场进行了四项关于单阶段孵化器中二氧化碳水平的实验。在孵化的前10天，向孵化器中注入二氧化碳，使其浓度达到0.3%。未注入二氧化碳的对照孵化器维持在0.1%的二氧化碳浓度。来自注入二氧化碳孵化器的种蛋孵化率更高，早期、晚期和胎位不正的胚胎死亡率更低。在孵化的前10天，0.3%和0.5%的二氧化碳浓度之间的孵化率没有差异。与在孵化的前10天注入二氧化碳相比，在孵化的前5天注入二氧化碳会降低孵化率。在孵化的前14天注入二氧化碳与在孵化的前10天注入二氧化碳相比，孵化率没有差异。由于人工添加二氧化碳对孵化率有影响，因此在商业孵化场中，向单阶段火鸡孵化系统中人工添加二氧化碳可能具有经济重要性。
