HYDROGEN ION CONCENTRATION{ PH) OF VAGINA AND VAGINAL SECRETION AND ITS RELATIONS WITH DIFFERENT REPRODUCTIVE STATES IN COWS

Abstract

This study was achieved on 75 cross breed cows ( Jarubi X fresian) , The PH of vaginaand its secretion was measured for all cows during the different oesturs phases ( proestrus estrusand l:uring different stages of pregnancy ) PH was measured by using PH paper. Results revealedthat aginal PH of cows tends to be alkaline during proestrus; estrus and during luteal phase butin case of pregnancy the vaginal PH becomes acidic on the contrary to that of ewes. Results alsoindicated that there is no significant effect of neither cows age nor pregnancy frequency on PHValues of cows vagina and its secretion; results also showed that vaginal PH and its secretion hadno signification effect on correlation between them.Results cleared that it is possible to diagnose pregnancy by means of PH values during this stages of pregnancy in an accuracy of 100% in pregnant cows confirmed by rectal
