摘 要:为了解孵化温度对种蛋出雏率的影响,试验采用21 d出雏法记录孵化厂内的5批种蛋,并对孵化机的温度、湿度、翻蛋次数、风门等进行记录,了解孵化出雏机各因素对出雏率的影响。结果表明:不同孵化温度下5批种蛋的孵化率分别为76.8%、77.7%、83.2%、68.3%、80.0%;温度设定1~3 d为38.0℃,4~6 d为37.8~37.9℃,7~12 d为37.8℃,13~18 d为37.6℃,19~21 d为37.3℃或1~18 d的孵化温度为37.8℃,出雏温度均控制在37.3℃,设定的孵化温度均能保证有较高的孵化率。说明孵化温度过高或过低都会严重影响孵化率。To understand the influence of temperature on egg hatching rate,5 batches of hatching eggs in the hatchery were observed using21 days hatching method,and the data of incubator temperature,humidity,times of turning over eggs,ventilation door were measured for understanding the influences of hatching factors on hatching rate. Results showed that the hatching rate at different incubation temperatures of 5groups was 76. 8%,77. 7%,83. 2%,68. 3% and 80. 0% respectively. The temperature was set as 38. 0 ℃ within 1 ~ 3 days,37. 8 ~37. 9 ℃ within 4 ~ 6 days,37. 8 ℃ within 7 ~ 12 days,37. 6 ℃ within 13 ~ 18 days,37. 3 ℃ within 19 ~ 21 days or 37. 8 ℃ within 1 ~ 18 days,and the hatching temperature was controlled at 37. 3 ℃ which can guarantee higher hatching rate. The results indicate that the incubation temperature at too high or too low level will seriously affect the egg hatching rate.
