Abstract
The aim of high-profitability grazing systems is to produce milk efficiency from grazed pasture. There is very limited information available on the milk production capacity of dairy cows offered a grass-only diet for the main part of her lactation. In this study, spring-calving dairy cows were managed to achieve high milk production levels throughout the grazing season without supplementation. The calving date of the herd was 12 April; the herd had access to grass as they calved and remained full-time at grass until 20 November. During this period the herd produced 5,513 kg milk, while receiving 130 kg concentrate supplementation. The herbage mass offered was ma...
