successful pasture-based milk production systems pivot on balancing dairy cows’ feed requirements with seasonal and annual fluctuations in pasture production. in order to maximise cow production from grazing dairy systems, it is necessary to reach an efficient utilization of grazed grass for feeding cows and the development of appropriate grazing management systems designed to maximize daily pa...

Adaptive Multi-Paddock (AMP) is a grazing system which combines intensive, rapid livestock rotation with relatively short periods and long recovery time after grazing. The study assesses, under Mediterranean silvopastoral systems, changes in pasture phenology spatial variability adopting the AMP contrasting land cover (Wooded Grassland vs ) remote sensing approach based on time-series analysis ...

We used a fully factorial experimental design to examine the effects of fire season, simulated grazing and their interaction on the temporal stability (year-to-year variation in production) of the C4 bunchgrass, Bouteloua curtipendula, the C3 bunchgrass, Nassella leucotricha, and the C4 lawngrass, Buchloe dactyloides. Treatments included three levels of fire (winter fire, summer fire, and no fi...

According to the nonequilibrium theory, livestock grazing has a limited effect on long-term vegetation productivity of semiarid rangelands, which is largely determined by rainfall. The communal lands in northeastern South Africa contain extensive degraded areas which have been mapped by the National Land Cover (NLC) program. Much evidence suggests that long-term heavy grazing is the cause of th...

Between January 1999 and December 2000 faecal samples from 16264 cattle at 12 dipping sites in the highveld and nine in the lowveld communal grazing areas of Zimbabwe were examined for gastrointestinal (GI) nematode and cestodes eggs, and coccidia oocysts. Strongyle larvae were identified following culture of pooled faecal samples collected at monthly intervals. The effects of region, age, sex ...
