- Abstract
Aim: The incidence of retained placenta of dairy cows in relation to individual animal level and farm management factors such as farm type, farm size, housing system, floor type, feed quality, time of parturition, farming experience of farmer and delivery pattern of cows was determined. Materials and Methods: A total 1205 parturated dairy cows conducted in nine upazilas and four Metro Thana of Rajshahi district during July 2010 to June 2011 for attainment of the result. Individual animal and farm management factors associated with retained placenta were recorded in a structured questionnaire through face-to-face farmer's interview and reviewing farm records. The raw data were compiled and statistical SPSS program to analyze to obtained result. Results: The overall incidence of retained placenta was 13.4%. The incidence was significantly higher in Local × Sahiwal genotype (4.6%) and late delivery (longer gestation period) (80%) than their counter groups (p<0.05). The large farm (6.0%) had higher incidence and had no significant effect than medium and individual household. Similarly animals housed in Tin shed building with poor ventilation facilities (6.6%), animal housed in unscientific concrete floor (6.8%), animals mostly grassed along with small amount of straw supplied (5.4%) and a farmer had less than one year farming experience (5.3%) had not significant statistically show higher incidence of retained placenta. Conclusion: The local genotype; mini farm; supplied better feed quality; vast farming experience of farmer and normal delivery with eutocia had less chance of retained placenta of dairy cows.
