| Abstract |
Thirty six pregnant Friesian cows were subjected to a regular blood sampling at 5 days intervals starting from day 250 of pregnancy up to delivery day. Plasma progesterone (P4), estradiol 17- β (E2), total protein, albumin (A), globulin (G), calcium and inorganic phosphorus concentrations were determined. Data were divided into 2 groups e.g. normal calved (N) and retained placental (RP) cows and it was confined to the last 25 days prepartum.
Plasma (P4) concetrations in (RP) were significantly lower (P<0.01) than in (N) cows from day 20 up to day 5 before calving. Such a difference in (P4) between (RP) and (N) cows varied from 25.3% at day 20 to about 57% at t/1e last 10 days prepartum. Concentration of plasma P4 sharply decreased in both (N) and (RP) cows at day 5 before calving compared to that found at day 10 prepartum. Concentrations of E2 in (RP) cows were higher at days 25, 20 (P<0.01) 15 and 10 (P<0.05) prepartum as compared to (N) cows. An opposite trend was noticed at day 5 before delivery. (E2) values progressively decreased with approaching day of calving in (RP) cows and the reverse was noticed in (N) cows. Ratio of P4/E2 significantly decreased (P<0.05) as the delivery time had approached in both (RP) and (N) cows, being lower (P<0. 05) in the former than that in (N) cows.
Concentrations of total protein (P<0.05) and albumin (A) (P<0.01) were significantly greater in (RP) cows compared to (N) calved cows, meanwhile globulin (G) concentrations did not significantly differ. A/G ratio was significantly higher (P<0.05) in (RP) cows. Plasma total protein, (A) and (G) did not significantly show variable values in late pregnancy with approaching delivery in (RP) or (N) cows. Plasma calcium and inorganic phosphorus were significantly lower in (RP) than that in (N) cows, suggesting that (RP) cows suffered from hypocalcemia and hypophosphatemia. Ratio of calcium to inorganic phosphorus was significantly lower in (RP) cows (P<0.05) at day 20 and 15 prepartum than in (N) cows.
