Abstract
To estimate secondary production of grazing pasture by breeding Japanese Brown cows, the method was investigated. The digestible energy (DE) requirements and animal productive energy for pregnancy and lactation were estimated by the existing formula and parameters. When the relationship between these estimated values and the practical DE intake and live weight gain has been considered, the both values corresponded well with energy balance. And it was shown that this method is available to calculate the DE requirement for maintenance which is important for grazing management of the breeding cows. These results suggested that this method can comprehend the out line of energy balance in the breeding cows under grazing and the results obtained by this method may be useful for the estimation of secondary production and for the management of pasture grazing by the breeding cows.
