Abstract

Dried distillers’ grains with solubles (DDGS) from bioethanol production can replace soya in diets for dairy cows, but optimum inclusion level of European wheat-DDGS (wDDGS) is unknown. Two batches of wDDGS from different UK bioethanol plants were fed to 44 (Experiment 1) and 40 (Experiment 2) cows in a Latin square design. Each wDDGS replaced soya and rapeseed at four inclusion levels (g/kg of diet dry matter (DM): 0, 80, 160 and 240 – Experiment 1; 0, 75, 150 and 225 – Experiment 2). Diets were balanced for metabolisable energy (ME) and protein (MP), and for minimum starch and saturated fat in Experiment 2. In Experiment 1, DM intake (29 kg/d) and milk yield (42.3 kg/d) were unaffected by wDDGS inclusion up to 160 g/kg but were lower than control with 240 g/kg inclusion, which was attributed to low proportion of solubles in this wDDGS batch. In Experiment 2, DM intake (22.4 kg/d) and milk yield (32.1 kg/d) were unaffected by wDDGS inclusion up to 225 g/kg. ME content of wDDGS, determined in vivo, (MJ/kg DM) was 12.1 (Experiment 1) and 13.4 (Experiment 2). It is concluded that optimum inclusion level of wDDGS is at least 225 g/kg DM in diets balanced for minimum starch and saturated fat as well as ME and MP supplies.
