Höjer, Annika; Martinsson, Kjell and Gustavsson, Anne-Maj (2010) PhytoMilk: Effect of silage botanical composition and harvest system on organic milk composition. In: Book of Abstracts of the 23rd General Meeting of the European Grassland Federation, p. 111.
The effect of silage botanical composition and harvest system on organic milk composition was studied in a feeding trial. Twenty-four Swedish Red dairy cows in mid lactation were allocated randomly to three treatments in a 3×3 Latin square design with each period of three weeks. The treatments were birdsfoot trefoil (Lotus corniculatus L.)/grass silage in two-cut system (B, 16 % birdsfoot trefoil), red clover (Trifolium pratense L.)/grass silage in two-cut system (R2, 42 % red clover) and red clover/grass silage in three-cut system (R3, 38 % red clover). Milk samples from the last week in each period were analyzed for fat and protein concentration. Milk yield was 28.7 ±1.0, 30.3 ±3.2 and 28.6 ±1.4 kg ECM day-1 (mean and SD) for treatment B, R2 and R3 respectively. Milk fat concentration was 5.00 ±0.38, 4.75 ±0.01 and 4.98 ±0.25 g 100 g-1 milk and milk protein concentration was 3.62 ±0.19, 3.54 ±0.08 and 3.57 ±0.09 g 100 g-1 milk for B, R2 and R3 respectively. Harvest system and botanical composition of silage does not seem to affect milk yield or composition.
