Development of balanced rations for milk cows on basis of biochemical constitution of grasses and fodders

The authors summarized the results of three-years investigations on the use of balanced rations considering the biochemical indices for feeding of milk cows of the Black-and-White breed. The rations for feeding of milch cows during stabling and summer periods were presented. The zootechnik expediency and economic effectiveness of developmental rations for manufacturing application were discussed.
