Abstract

The collagenase administration through umbilical artery is the effective treatment for Retained Fetal Membrane (RFM) in dairy cows. RFM was treated with collagenase enzyme through jugular vein as it is easy route than previous study of experimenting on umbilical arteries which is very difficult in a delayed case in field conditions in bovines. The study was conducted in bovines with RFM and presented within 12 to 24 hours after parturition to Obstetrics Unit of Madras Veterinary College, Chennai). Data on time of expulsion of foetal membrane, duration of lochial discharge and gross appearances was collected, compared and analyzed.The experimental animals were divided in to four different treatment groups (Gp:n=7; Gp:n=15; Gp:n=15; Gp:n=15). The findings showed that the expelled foetal membrane were bulky and shiny appearance in group I; shreds of foetal membranes with voluminous discharge in group II, remnants of digested foetal membrane with resisted umbilical vessels in group III and dark coloured remnants of digested foetal membrane with resisted umbilical vessels in group IV. The mean time taken for the foetal membrane expulsion was significantly shorter (P<0.01) in group I (6.00 ± 0.69 h) and longer in group II (126.40 ± 6.8 h) than group III (38.93 ± 2.54 h) and IV (50.60 ± 0.76 h). The mean duration taken forlochial discharge in group I (5.00 ± 2.16 h) and III (6 ± 2.25 h) had significantly (P<0.01) shorter than group II (15.00 ± 0.78 h) and IV (10 ± 3.36 h).
