RETAINED PLACENTA AND INFERTILITY - INTEREST OF ETIPROSTON TREATMENT AND PREGNANCY-ASSOCIATED GLUCOPROTEIN-I (PAGI) MEASURE IN COW

Sixty Prim'holstein cows with retained placenta for more than 24 hours after parturition, were shared in three groups of 20 cows each. All c ows were delivred manually 24 to 36 hours post partum and received loc al treatment with 1 g of oxytetracyclin. Cows in group I received two intra-muscular injections of 5 mg etiproston on day of manual delivery (D1) and 15 days after (D15). Cows on group II received only one etip roston administration (D1), and cows in group III remained untreated. Ratios of delayed uterine involution were respectively 20, 40 and 55 % in groups I, II and III (I < II, p < 0.05; II < III, p < 0.005). PAGI concentrations were checked 15 days after parturition and were signif icantly higher in cows affected by delayed uterine involution (pi 0.05 ). V-IAF intervals were significantly (p < 0.05) different between gro ups I(58 days), II (102 days) and III (143 days).
