HORMONAL TREATMENT TO PREVENT THE RESIDUE OF PLACENTA IN COWS

Abstract

Excreting of fetal remains (placenta) after calving (born of the fetus) is a physiological process that consists in the loss of the relationship between parent and fetus. Excreting the placenta generally occurs about 6-12 hours after born of the fetus. Remain of the placenta after 24 hours after the fetal born, the diagnosis is the residue of the placenta. According to some researchers the incidence of residual placenta ranges from 4-16%, but can be higher on farms with problems. In accordance with these problems, we start up this study, to clarify the role of hormonal treatment on the process of excreting the placenta in cows. For this purpose, we formed three groups with 10 cows each. Two experimental groups were treated as follows: The first group got 30 UI oxitocin + 50 ml Calcium Gluconat. Time of treatment: immediately after post partum. The second group got 2 ml PGF 2 alpha (Clorprostenole) + 50 ml Calcium Gluconat. Time of treatment: immediately after post partum. While the control group (10 cows) received no special treatment. The results obtained from this study indicate that the combination of oxitocin together with Calcium Gluconat, 2 out of 10 cows treated have residue of placenta (20%), from the combination of PGF 2 alpha together with Calcium Gluconat, 4 out of 10 cows treated have residue of the placenta and after 24 hours of treatment (40%), whereas in the control group it appears that 4 out of 10 surveyed cows have residue of placenta (40%). So, the combination of the oxitocin together with Calcium Gluconat is more effective.
