摘要:

 旨在研究藏鸡作为父本和母本对杂交种蛋胚胎低氧发育的影响。在模拟常压低氧的条件下对纯种藏鸡(TT)、纯种茶花鸡(CC)、藏鸡♂×茶花鸡♀(TC)、茶花鸡♂×藏鸡♀(CT)种蛋进行孵化。而后对种蛋的低氧孵化性能进行测定。结果显示,在13%氧浓度(约海拔3 980 m)条件下,藏鸡与茶花鸡正反交种蛋孵化率(36.41%、39.57%)显著高于茶花鸡(16.97%),藏鸡作为母本的种蛋失水率显著低于茶花鸡为母本组,且蛋重较大。本研究说明了种蛋的蛋重、孵化期失水率主要由母本决定;茶花鸡与藏鸡的杂交种蛋低氧孵化率显著提高,表现较强杂种优势,但正反交组间种蛋低氧孵化率差异不显著;藏鸡作为母本的种蛋低氧孵化胚胎发育前期优于藏鸡作为父本组,后期则藏鸡作为父本的种蛋胚胎发育能力较好。

Abstract:

The aim of this study was to investigate the effect of Tibet chicken as male and female parents on hypoxia development of hybrid eggs.Eggs from Tibet × Tibet (TT),Chahua × Chahua (CC),Tibet × Chahua (TC) and Chahua × Tibet (CT) chickens were incubated under hypoxic condition.Then the hatchability of eggs were examined.The results showed that the hatchability of TC (36.41%) and CT (39.57%) groups were significantly higher than that of CC group (16.97%) under 13% oxygen concentration (equivalently 3 980 m altitude).Eggs from Tibet hens (including TT and CT groups) had a higher egg weight and a lower water loss during incubation than eggs from Chahua hens (including CC and TC groups).The results indicated that the egg weight and the water loss during incubation were mainly determined by female parent.The intercrossing eggs between Tibet chicken and Chahua chicken had higher hatchability and had stronger heterosis in traits of hypoxic hatchability.There was no significant difference in hypoxic hatchability of eggs between TC and CT groups.The embryo development of eggs from Tibet chicken as female parent was better at early stage and embryo development of eggs from Tibet chicken as male parent was better at last stage under hypoxic incubation.
