Fig 3

Treatments: Control (gray line, n = 128) cows supplemented with 78 g of Energy Booster 100 (Milk Specialties Global, Eden Prairie, MN) and CLA (black line, n = 138) cows supplemented with 100 g/day of Lutrell Pure (BASF, Ludwigshafen, Germany). Supplementation was by individual topdress of product mixed with 200 g corn gluten feed for 16 days prepartum. Hazard ratio (95% confidence interval) and Hazard ratio P-value were 0.99 (0.75 to 1.31) and P = 0.95. Mean ± standard error were 107.7 ± 3.00 for control and 107.4 ± 2.99 for CLA treatments. Median (95% confidence interval) were 106.5 days (75 to 110 days) for control and 105.5 days (75 to 110 days) for CLA treatments. LogRank P = 0.97, and Wilcoxon P = 0.96.
