'n Vergelyking tussen mieliekuilvoer stoekmielies en ryp mielie plante
Mieliekuilvoer, stoekmielies en ryp mielieplante afkomstig van 'n eenvormige blok mielies is met behulp van'n opbrengs-, metabol isme- en produksiestudiem et mekaar vergelyk. Droemater iaalver l iesien die kui lvoer tor ing was 8,% of the original harvested dry matter was lost in the silo, the comparable field loses for stover amounted to 13,33/o anC for ripe plants to 34.9ft. No remarkable differences in chemical composition were found between the original plant matter, the silage, the stover and the mature plants. In metabolism studies with sheep, the lowest dry matter intake was obtained with silage, whilst the highest intake was obtained on stover. The highest digestible energy values were, however, recorded on silage feeding. The production study with oxen showed that the feeding of silage proved to be more efficient with regard to increase in body mass, dressing percentage, carcass mas and total income
Imports and isotopes: a modern baseline study for interpreting Iron Age and Roman trade in fallow deer antlers
The European Fallow deer (Dama dama dama) became extinct in the British Isles and most of continental Europe at the time of the Last Glacial Maximum, with the species becoming restricted to an Anatolian refugium (Masseti et al. 2008). Human-mediated reintroductions resulted in fallow populations in Rhodes, Sicily, Mallorca, Iberia and other parts of western Europe (Sykes et al. 2013). Eventually, the species was brought to Britain by the Romans during the 1st century AD, with a breeding population being established at Fishbourne Roman Palace (Sykes et al. 2011). The human influence on the present-day distribution of the species makes it particularly interesting from a zooarchaeological perspective.
This paper describes my MSc research, as part of the AHRC-funded project Dama International: Fallow Deer and European Society 6000 BC–AD 1600, looking at antlers from Iron Age and Roman sites in Britain for evidence of trade in body parts and whether this can be elucidated by a parallel stable isotope study of modern fallow antlers of known provenance
