Effects of different conservation methods on beta -carotene content of alfalfa and orchardgrass



Effects of different conservation methods on beta -carotene content of alfalfa and orchardgrass



Japanese Journal of Zootechnical Science 57(11): 881-886



First-cut Medicago sativa and Dactylis glomerata hays were chopped and (a) dried in the shade, (b) treated with anhydrous ammonia for 10 days at 39% moisture content or (c) treated with microwave radiation before drying; silages were ensiled with (d) 20 g glucose/kg, (e) 6 ml formic acid/kg or (f) 8 ml formalin/kg. beta -carotene content decreased with time in all forages, particularly in the first 4 weeks after treatment but the decrease was least with (d) and most with (b).
