1 The TMR was supplemented with sodium-chloride, sodium-bicarbonate, and bacterial inoculum for unifeed stabilisation. 2 Cows in the housing group received a supplement of soybean (1.0 kg/day), faba bean (0.5 kg/day), and hay ad libitum, which was consumed at an average amount of 4.8 kg/day per head.
