Effects of herbage mass and herbage quality on spatially heterogeneous grazing by cattle in a bahia grass ( Paspalum notatum ) pasture
Small-scale patches (locations of 50 cm × 50 cm at a feeding station level) in a bahia grass ( Paspalum notatum ) pasture under cattle grazing were investigated in terms of herbage mass, quality and utilisation during a grazing season (May–November), to characterise the quantityquality relationship of patches and relate this to spatially heterogeneous grazing by animals. Nitrogen concentration ...
متن کاملEffects of cattle grazing on herbage quality in a herbaceous Mediterranean rangeland
The main objective of this study was to determine to what extent grazing pressure and timing modulate the seasonal progression of herbage quality in hilly Mediterranean grassland systems. The study was conducted during six consecutive years between 2003 and 2008 at the Karei Deshe experimental farm, in eastern Galilee, Israel, dominated by rich hemicryptophytic grassland. Treatments included tw...
متن کاملSome effects of a rotational grazing treatment on cattle grazing behavior
Research was conducted on the effects of rotational grazing (RG) compared to continuous grazing (CG) on the behavior of cattle grazing on rangelands. Different livestock den&tics in the RG treatments were created by varying the size of paddocks in a 4651a, U-paddock, cell deaigntd RG treatment stocked at a rate of 3.6 ha/cow/yr. Paddock sizes of 30 and lo-ha were used to simulate RG with 14 (RG...
متن کاملThe utilization of herbage protein by animals.
CONFERENCE PRO,CEEDINGS '952 recently the work of Legg, Curnow & Simpson (1950) has focused attention on the oestrogens in grass which they show tend to be higher in spring grass. Then again there is the marked laxative effect of young grass, particularly for cattle that have just been turned out, a factor which markedly affects its value at that time. Finally, we have troubles such as blowing ...
متن کاملSimulating rotational grazing management.
Dairy systems predominantly based on rotational grazing are notoriously hard to manage. In order to ensure profitability, this type of production requires quite good organisation, planning, and operating capability on the part of the farmer. A simulation-based decision support system, called SEPATOU, has been developed for this purpose. At the core of the decision support approach lies an expli...
