Popis:	Retained placenta (RP) is a common complication of bovine parturition. It is a multifactorial reproductive disorder that predisposes to infection and hence, to infertility. The impact of body condition changes during the transition period on the risk of RP appearance was evaluated in 12 Holstein dairy cows calving from October to January in north-eastern Algeria. The animals were body condition scored (BCS) 3 weeks antepartum and two weeks postpartum to assess the peripartum body fat loss (BCS loss). The statistical analysis involving variables related to BCS and parity was performed using the principal component analysis (PCA). An RP critical occurrence of 41.66% exceeding significantly the threshold prevalence of 10% (p
