Table 1 Means ± SE and ANOVA P-values for the estimated dry matter (DM) intake (DMI) and dietary components (% of DMI) in 73 individual cows from two breeding groups (100% Holstein-Friesian, HF; 50% Holstein-Friesian:50% Jersey, HF × J) and different seasons in four low-input dairy farms in England and Wales.

¹ n is the number of records used to calculate means.
² Significances were declared at P < 0.05. Means within a row, for season, with different upper-case letters are significantly different according to Fisher’s protected least significant difference test (P < 0.05).
