Increasing digestible undegradable protein (DUP) in concentrates fed to triplet-bearing ewes can help increase lamb output on low maintenance systems, despite having little effect on lamb birth weight or colostrum production. Mixed breed ewes fed on a grass-based diet supplemented with a 20% concentrate for six weeks before lambing reared most lambs at an optimal concentrate DUP level of 70-80g⁄kg DM. Researchers suggest increasing DUP levels fed may improve colostrum composition, thereby increasing lamb survival on easy-care systems.
