ABSTRACT: Timothy (Phleum pretense L.) pastures of 3 Total mixed ration (TMR) centers in Hokkaido were
selected, the first cutting grasses were continuously collected from the same
pastures on different harvest days over 4 years (2011-2014), and changes in the
water soluble carbohydrates (WSC) content were analyzed to investigate the
relationship with weather conditions. The harvest days in the 4-year period
were June 17-22, June 24-26, June 27-30, and July 2-5, and grasses on these
dates were designated as the harvest date groups. The weather data during the
cutting period in each year were utilized. The WSC content tended to change
yearly and it was significantly lower in the 4 groups (67.3 - 82.1 g/kg DM) in
2011 than in the groups (101.5 - 130.3 g/kg DM) in 2013 excluding the June
24-26 group (P
