| 英文摘要 | To study the effect of donor age on oocyte developmental competence and steroid profiles, the crossbred cow (Murray Grey x Brahman) in Yunnan province of China were selected and divided into three groups according to its age. The three groups were young cows (n = 12; 12 months old), middle-aged cows (n = 15; parity: =3 calvings; age: 78 years old) and old cows (n = 10; parity: =8 calvings; age: =15 years old). Cumulusoocyte complexes (COCs) were collected by 10 consecutive ovum pick up (OPU) sessions with a 4-day interval between each session, followed by in vitro maturation, fertilization and embryo development. Results showed that cleavage rates (CR) and blastocyst rates (BR) were higher in the young cows than those in the middle-aged and old cows (p < 0.05). CR and BR from COCs of the first and the fourth OPU sessions were lower than those from other sessions in the young cows and the middle-aged cows (p < 0.05), whereas the similar phenomenon was not observed in the old cows. Plasma concentrations of oestradiol were higher, and plasma concentrations of progesterone were lower before and during OPU sessions in the young cows compared with those in the same period in the middle-aged cows or the old cows (p < 0.01). In conclusion, donor age of oocytes could affect developmental competence of oocytes recovered by OPU through the action of steroid hormonal balance on follicle development. |
