Amylase activity in cerical mucus and serum during estrus in normal and repeat breeder cattle
نویسندگان
چکیده
Aim: To compare the amylase activity in the cervical mucus and serum during estrus in normal and repeat breeder cattle and find out importance in fertility. Materials and methods: Twenty cyclic crossbred cattle were divided into two groups: normal (n =10) and repeat breeder (n =10). Animals exhibiting spontaneous estrus, were artificially inseminated (AI) twice, as per AM-PM schedule along with simultaneous collection of cervical mucus and blood. Amylase activity was measured by using kits in collected samples. Result and discussion: Cervical amylase activity was significantly (p<0.01) higher in normal compared to repeat breeder animals showing important role of cervical amylase in fertility without significant difference in serum profiles between these groups. Conclusion: Results of study suggest that cervical mucus amylase could be a facilitator of sperm transport and capacitation process in female genital tract leading to acceptable fertility in normal animals.

Sixty-four zebu cows, comprised mainly of Bunaji cattle aged between 3 and 7 years old, were involved in an intensive artificial insemination programme. The study was conducted during the breeding period (May-October), and cows were inseminated with freshly prepared Friesian semen when they stood to be mounted by the vasectomised bull or herdmates. Fertility was measured by serum progesterone (...
