Fig 5
Box plot of milk phosphorus (P) and calcium (Ca) concentration for Holstein and Jersey cows (complete dataset, Table 1).
Milk P mean (95% confidence interval): 0.90 (0.89, 0.92) g/kg milk (n = 135 treatment means) for Holstein; and 1.00 (0.96, 1.04) g/kg milk for Jersey (n = 41). Milk Ca mean (95% confidence interval): 1.18 (1.12, 1.23) g/kg milk (n = 56 treatment means) for Holstein; and 1.38 (1.28, 1.47) g/kg milk for Jersey (n = 47).
