Abstract

Twelve Ayrshire cows in a 16-week changeover design experiment were offered 8 kg hay per day together with a daily supplement of either: A, 8 kg concentrates; B, 6 kg concentrates and 4·5 to 50 kg draff/syrup mixture; or C, 4 kg concentrates and 9·0 to 10·0 kg draff/syrup mixture. The concentrate and the draff/syrup mixture had dry-matter concentrations of 872 and 385g/kg, and contained 229 and 255 g crude protein per kg dry matter respectively. Total daily intakes of dry matter were 13·77, 13·80 and 13·81 kg per cow for treatments A, B and C respectively, and were not significantly different. The mean daily milk yields for treatments B and C were 18·2 and 18·5 kg per cow respectively, and were significantly higher than the yield of 17·3 kg per cow for treatment A. The solids-not-fat and lactose concentrations in the milk, and the mean live weights, were also significantly higher for treatment C than for treatment A. Based on the differences in milk yield and composition between treatments, it was estimated that the metabolizable energy value of the draff/syrup mixture was 12·2MJ/kg dry matter. It is concluded that the draff/syrup mixture was a safe and acceptable food for dairy cows when it replaced half of the concentrate dry matter.
