The effect of extended underfeeding on digestion was studied in dairy cows. Four nonlactating cows (BW = 747 kg) were first fed a forage-based diet at a level above energy maintenance requirements for 7 wk (9.4 kg DM/d) then were restricted at a low level of intake of the same diet for 5 mo (5.2 kg DM/d), then refed at the first level. Digestion measurements were made before and after the underfeeding period, and at 1, 5, 9, and 19 wk of underfeeding. Organic matter digestibility decreased with… CONTINUE READING
