Predicting Fertile Oestrus On The Basis Of Plasma Progesterone and Some Metabolites in Buffaloes

A study on 225 normal cyclic buffaloes revealed that the plasma progesterone concentration at fertile
oestrus was significantly (P < 0.0 I) lower than the infertile oestrus (0.26 ± 0.02 vs 0.97 ± 0.13 ng/ml).
Pregnancy occurred only in animals having basal progesterone level (< 0.3 ng/ml) at Al. The mean values of
plasma glucose, total protein and total cholesterol concentration observed at oestrus in buffaloes were 57.65 ±
0.52 mg/di, 7.92 ± 0.07 g/dl and 113.75 ± 2.82 mg/di, respectively. The levels neither varied significantly
between fertile and infe1tile oestruses nor between village centres, though the plasma total cholesterol was low at
fertile oestrus.
