1.使用连续喷雾消毒机对肉鸡种鸡群的鸡蛋进行消毒。在整个生产周期中，研究了这种处理对角质层抗水和抗细菌渗透能力的影响。消毒后鸡蛋的吸水量显著高于对照鸡蛋(P<；0.00 1)。消毒鸡蛋的吸水量随着鸡龄的增加而增加，而对照鸡蛋在42周龄时吸水量最大。消毒鸡蛋和对照鸡蛋的吸水率与蛋壳厚度和蛋重之间没有相关性。消毒过的鸡蛋倾向于在所有鸡群年龄中占主导地位，当使用Edicol Supra Pea Green染料对角质层质量进行主观评估时，角质层质量差的类别占主导地位。鸡蛋消毒处理不影响蛋壳反射率、蛋壳厚度和破壳率。当鸡龄达到49周龄时，消毒处理显著降低孵化率(P<；0.00 1)。
1. Eggs from a broiler breeder flock were sanitised using a continuous spray sanitising machine. The effect of this treatment on the ability of the cuticle to resist water and bacterial penetration was investigated throughout the production cycle.2. The volume of water taken up by eggs that had been sanitised was significantly (P < 0.00 1) greater than that taken up by the control eggs. The volume of water taken up by the sanitised eggs increased as the flock age increased, whereas water uptake was maximal for the control eggs at 42 weeks of age.3. There' was no correlation between water uptake values and shell thickness or egg weight for either the sanitised or control eggs.4. Sanitised eggs tended to dominate the ''poor cuticle quality'' category at all flock ages, when a subjective assessment of cuticle quality was made using the stain Edicol Supra Pea Green.5. Egg sanitising did not affect shell reflectance values, shell thickness or the percentage of cracked shells.6. When flock age reached 49 weeks of age, the sanitising process significantly (P < 0.00 1) reduced hatchability.
