Description
We have been studying high forage feeding for dairy cattle without reducing the efficiency of utilization of energy. In our previous report (Sekine et al., 1987), the net efficiency of utilization of ME for lactation (kl) was the same (0.54) when cows were fed concentrate at rates of 25 and 35 % of milk yield. There is little information on the long-term effects of feeding pasturage and corn silage as the main forage on milk production and efficiency through successive lactation cycles. The objective was to evaluate high forage diets over the entire lactation of dairy cows, mainly pasturage during grazing season and corn silage in winter.
