摘要/Abstract

摘要： 为研究不同输氧浓度对拉萨白鸡种蛋孵化效果的影响,选用5世代拉萨白鸡种蛋进行孵化。试验分为8组,每组各1 000枚拉萨白鸡种蛋,对照组全程不输氧,试验1组的氧气浓度为21.00%~22.50%,试验2组的氧气浓度为22.51%~23.50%,试验3组的氧气浓度为23.51%~24.50%,试验4组的氧气浓度为24.51%~25.50%,试验5组的氧气浓度为25.51%~26.50%,试验6组的氧气浓度为26.51%~27.50%,试验7组的氧气浓度为27.51%~28.50%。结果表明,试验7组的总出雏数、健雏个数、健雏率、入孵蛋孵化率、受精蛋孵化率均最高,分别为：851羽、813羽、95.53%、85.10%、91.21%;试验7组的头照死胚个数、死精率、二照死胚个数、弱雏率、毛蛋个数、死胎率均最低,分别为：18枚、1.93%、29枚、3.88%、35枚、3.75%;对照组的无精蛋个数、头照死胚个数、死精率、二照死胚个数、死雏个数、死雏率、毛蛋个数、死胎率均最高,分别为：68枚、87枚、9.33%、146枚、8枚、1.42%、136枚、14.59%;对照组的受精蛋个数、受精率、总出雏数、健雏个数、健雏率、入孵蛋孵化率、受精蛋孵化率均最低,分别为：932枚、93.20%、563羽、529羽、93.96%、56.30%、60.40%;试验2组的弱雏率均最高,为4.88%;试验6组的受精蛋个数、受精率、弱雏个数均最高,分别为：942枚、94.20%、37羽;试验6组的无精蛋个数、死雏率均最低,分别为：58枚、0.49%。通过该试验,为拉萨白鸡种蛋在高原上进行供氧孵化试验提供理论参考。

Abstract: In order to investigate the effect of oxygen supply with different concentrations on the hatching of Lhasa white chicken breeding eggs, the 5^th generation Lhasa white chicken breeding eggs were selected for hatching. A total of eight groups were included in this study, and there were 1 000 Lhasa white chicken breeding eggs for each group. The control group did not receive oxygen supply during the whole experiment. The oxygen concentration range supplied for experimental group 1 to 7 were 21.00%-22.50%, 22.51%-23.50%, 23.51%-24.50%, 24.51%-25.50%, 25.51%-26.50%, 26.51%-27.50%, and 27.51%-28.50%, respectively. During and at the end of the experiment, the indicators associated with hatching of Lhasa white chicken breeding eggs in different groups were recorded, calculated and compared. The results showed that the total number of hatchlings （851）, the number of healthy hatchlings （813）, the healthy hatchling rate （95.53%）, and the hatching rate of hatched eggs （85.10%） and fertilized eggs （91.21%） in the experimental group 7 were the highest; the number of dead embryos （18） at first candling, the sperm death rate （1.93%）, the number of dead embryos at second candling （29）, the weak hatchling rate （3.88%）, the number of hairy eggs （35）, and the stillbirth rate （3.75%) in the experimental group 7 were the lowest; the number of non-spermatozoa eggs （68）, the number of dead embryos at first candling （87）, the sperm death rate （9.33%）, the number of dead embryos at second candling （146）, the number of dead hatchlings （8）, the rate of dead hatchlings （1.42%）, the number of hairy eggs （136）, and the stillbirth rate （14.59%） in the control group were the highest; the number of fertilized eggs （932）, the fertilization rate （93.20%), the total number of hatchlings （563）, the number of healthy hatchlings （529）, the healthy hatchling rate （93.96%）, and the hatching rate of hatched eggs （56.30%） and fertilized eggs （60.40%） in the control group were the lowest; the experimental group 2 had the highest weak hatchling rate of 4.88%; the highest number of the fertilized eggs （942）, the fertilization rate （94.20%） and the number of weak hatchlings （37） were observed in the experimental group 6, and the lowest number of the non-spermatozoa eggs （58） and the rate of dead hatchlings （0.49%） were also found in this group. This study provides a theoretical reference for the hatching experiments of Lhasa white chicken breeding eggs at oxygen supply condition conducted in the plateau.
