Predisposing factors for culling in first lactation Holstein-Fresian heifers
The high culling rate in dairy herds is one of the most important problems for dairy farmers (Tena-Martinez et al., 2009). Culling in first lactation dairy heifers can be as high as 33% (Wathes et al., 2007), and both culling and infertility reduce farm profitability. Reasons for culling of dairy cows have been well documented (Bascom and Young, 1998). However, studies examining the predisposing factors and characteristics of first lactation heifers that do not progress to subsequent lactations are sparse. The objective of the current study was to identify traits that predispose first lactation heifers to an increased risk of culling.
