Abstract

The present study was designed to estimate changes in salivary pH, electrical conductivity (EC) and its various constituent biomolecules like total carbohydrates, total proteins, albumin, mucin 5 and total lipids, during different phases of estrous cycle. In present investigation, the levels of all biomolecules like total CHO, total proteins, albumin, mucin 5, total lipids and EC were observed to be significantly (P<0.01) higher during estrus phase compared to all other phases. No significant difference was found in pH of saliva during different phases of estrous cycle. These changes may be helpful in explaining the relationship between characteristics of saliva and ovarian hormones viz. preovulatory estrogen surge. Thus, variation in salivary composition during different phases of estrous cycle may be helpful in accessing the specific phase of estrous cycle and carrying out the timed AI programme more precisely.
