Retention of placenta and its associated factors in Bangladeshi zebu cattle
Keywords:Retention of placenta, zebu cattle
The aim was to find out the incidence of retention of placenta in 175 zebu cattle with regard to age, body condition score (BCS), parity, and feeding system. Pretested questionnaire was used for collecting the information. The overall incidence of manually removed placenta was 10.3%. Age, body condition score and feeding system had significant effect (P<0.05) on incidence of manual removal of placenta. The effect of parity was not significant. The highest incidence of 14.3%, 16%, 11.8% and 12% was in cows over 7 years of age, 6th parity, poor BCS and stall-feeding, respectively. It is suggested that animals aged 4 to 7 years, fair body condition, and free-range grazing were less susceptible to retained placenta.
