Performance of extensive cattle stocking on a reclaimed minerotrophic wet grassland
Extensive stocking with cattle is a common type of grassland management in reclaimed fen sites. However, due to the high productivity of grassland on organic soil with a history of intensive management, stocking at low rates may not allow an adequate balance of herbage production and utilisation.

| description | Extensive stocking with cattle is a common type of grassland management in reclaimed fen sites. However, due to the high productivity of grassland on organic soil with a history of intensive management, stocking at low rates may not allow an adequate balance of herbage production and utilisation. In the present study we examined the agronomic performance of an established (6-year) extensive cattle grazing system on a reclaimed fen grassland site in north-western Germany during the course of the grazing season. We regularly quantified the amount and energy content of herbage on offer based on compressed sward height (CSH), the spatial extent of patches of various degrees of grazing intensity (heavily or moderately grazed, non-grazed), and the chemical composition of the herbage, and assessed energy uptake and livestock performance in terms of live weight gain of the cattle. We deduced herbage utilisation from these data and quantified functional relationships between cattle grazing and the properties of the sward. Our data show that there was an inadequate balance between quantity and quality of forage on offer on the one hand, and demand and forage consumption by livestock on the other. As a result, live weight gains showed a seasonal pattern with a minimum in summer. The amount of energy on offer per animal unit had a significant effect on the sward structure, i.e. on both the area proportion of heavily grazed patches and the heterogeneity of CSH. These findings may be of interest in the context of conservation management of reclaimed fen grasslands, as they may contribute to the design of grazing regimes aiming to create particular sward structures, e.g., to provide habitat for individual target species. |
