A mathematical model of browse and herbage production in communal grazing lands of semi-arid regions
… an existing model of growing cattle and grass production in a semi-arid rangeland.The existing model which is basically Dye's (1983) model in differential equation form handles: i) the growth and performance of cattle measured in terms of weight, ii) the initiation of grass growth in early …

White clover inclusion in intensive dairy production systems
Incorporating white clover into intensive dairy production systems has the potential to increase their sustainability through increased milk output and reduced nitrogen (N) input. To support intensive stocking rates (<2.75 cows/ha) some inorganic N will still be required to support herbage …

A qualitative analysis of the southern pine beetle's (Dendroctonus frontalis Zimm.) impact on wildlife, wildfire, and grazing
… impacts given SPB spot size and incidence, the herbage production before attack, and the residual basal area in hardwoods. The results indicated that SPB grazing impacts were also too small to be considered in SPB control decisions.

Competitive interactions in a dairy pasture containing paspalum (Paspalum dilatatum Poir,) following the introduction of ryegrass (Lolium perenne L.)
… perenne and Bromus catharticus) to seasonal production of a high yielding dairy sward containing paspalum (Paspalum dilatatum). The persistence of the introduced species was also determined. Autumn overdrilling improved (<500 kg DM/ha) herbage production in the following winter/spring and …

The influence of ryegrass sowing rates and nitrogen fertiliser on white clover establishment : A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
… Ryegrass and white clover seedling development, herbage production, botanical composition, herbage nitrogen percentage and grazing preference of autumn sown pastures were assessed. There was no advantage in terms of dry matter production from sowing greater than 10 kg/ha. Total dry matter from at …

The effect of altering autumn grazing management on sward structural characteristics, morphology and nutritive value
… management practices to increase the amount of herbage available on farm can help extend the grazing season, improve herbage utilization and, in turn, improve the sustainability and efficiency of pasture based dairy systems. Extended grazing happens at two pivotal time points - autumn and …
