Amylase activity in cerical mucus and serum during estrus in normal and repeat breeder cattle

Abstract

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.
