The effects of four temperature regimens on the onset and maintenance of semen and egg production, fertility, hatchability, and feed consumption by guinea fowl were examined. Temperatures of 26.7 and 21.1 C hastened the onset of egg and semen production in guinea fowl. However, egg and semen production rates of guineas exposed to ambient or 15.6 C minimum temperatures eventually increased to the level of those exposed to the higher temperatures. This suggests that it may be possible to initiate production by exposure to a warm environment and then reduce the environmental temperature after egg and semen production has been well established. There were no statistically significant differences in fertility or hatchability. Differences seen in feed conversion were mainly due to delayed onset of egg production in the lower temperature regimens. Thus, it appears that proper winter management of guinea breeders would involve exposure to a warm temperature for some period of time.
研究了四种温度方案对珍珠鸡精液和蛋的生产起始及维持、受精率、孵化率和采食量的影响。26.7摄氏度和21.1摄氏度的温度加速了珍珠鸡产蛋和产精的起始。然而，暴露于环境温度或最低15.6摄氏度的珍珠鸡的产蛋率和产精率最终会提高到暴露于较高温度的珍珠鸡的水平。这表明，有可能通过暴露于温暖环境来启动生产，然后在蛋和精液生产充分建立后降低环境温度。受精率或孵化率没有统计学上的显著差异。饲料转化率的差异主要是由于较低温度方案中产蛋起始延迟。因此，看来对珍珠种鸡进行适当的冬季管理需要在一段时间内暴露于温暖的温度下。
