Retained Placenta of Dairy Cows: Retained Placenta of Dairy Cows with Special Reference to Some Prophylactic Trials Md. Jalal Uddin Sarder

The prevalence of retained placenta of 1205 cows observed in relation to breed, age, body weight, body condition score, parity, season and managemental factors. Genotype of L×SL (4.6%), <3 yrs of age (4.5%), 150 to <250kg body weight (6.4%), fair body condition (7.1%), first parity (5.6%), private dairy farm (11.9%), large sized farm (6.0%), medium housed (6.6%), medium floor condition (6.8%), fed poor quality feed (5.4%) semi-illiterate (5.6%), no farming experience (5.3%), artificially inseminated (11.7%) and normal gestation length (6.2%) & normally delivered (9.5%) cows and summer season (6.2%) of the year. The application of prophylactic drugs was as follows: Group I (n=20) Oxytocin synth @ 5 ml/ cow i/m); Group II (n=20) Methyleargometrine meleate @ 5 ml/ cow i/m); Group III (n=20) PGF2? @ 5 ml/ cow i/m); Group IV (n=20) Herbal Medicine @ 450 ml/ cow orally); Group V (n=20) Control (without drugs). The logistic regression coefficients were found to be positive in all cases whereas only Dinoprost (P<0.05) and Metherspan (P<0.01) was statistically significant. Immediate therapeutic approach after delivery will reduce the chance of retained placenta of dairy cows.
