Reference


Heifer raisers were eligible for inclusion in the study if they were either: (1) offsite multi-source heifer raisers (MULTI) that raised heifers from at least two farms, or (2) on-farm heifer raisers (HOME) that raised heifers from only that farm. A total of three MULTI raisers and three HOME raisers were enrolled in the study. Herds were selected from a convenience sample of commercial dairy farms within a 3-h radius of Cornell University.

The same number of pooled fecal samples collected from animals that had arrived at the farm in the previous 2 months (AP) and from animals thath would be departing the heifer raiser in 2-3 months (DP) during the farm visit were allso collected during the following farm visits. Pooled fecal samples consisted of 5g feces randomly collected from each of three freshly passed fecal pats from different corners of the pen floor
