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: 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.
