Hydrogen ion concentration (PH)‎ of vagina and vaginal secretion and its relations with different reproductive states in cows

الملخص EN

This study was achieved on 75 cross breed cows ( Jarubi X fresian) , The PH of vagina and its secretion was measured for all cows during the different oesturs phases ( proestrus estrus and l:uring different stages of pregnancy ) PH was measured by using PH paper.

Results revealed that aginal PH of cows tends to be alkaline during proestrus; estrus and during luteal phase but in case of pregnancy the vaginal PH becomes acidic on the contrary to that of ewes.

Results also indicated that there is no significant effect of neither cows age nor pregnancy frequency on PH Values of cows vagina and its secretion; results also showed that vaginal PH and its secretion had no 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
