A NEW NITROGEN FERTILISATION REGIME FOR MINIMUM-TILLAGE KIKUYU-RYEGRASS PASTURE IN THE SOUTHERN CAPE.

The sustainability of current nitrogen (N) fertilization regimes for minimum tillage kikuyu-ryegrass (Pennisetum clandestinum, Lolium multiflorum) pastures in the southern Cape is questioned. The guidelines, originally, were developed for conventional tillage and non-grazing systems. It may well be that these guidelines may not apply any more. In fact, there is the possibility that the N levels applied are too high with implications to both economics and leaching of unutilised N.

E.COLI AND OTHER ENTEROBACTERIACEAE IN BULK MILK.

Members of the Enterobacteriaceae family have been associated with food safety and spoilage problems. Enterobacteriaceae can enter an inadequately cleaned dairy chain and cause enzymatic breakdown of proteins or lipids, instigating spoilage which contributes to substantial economic losses and wastage. Some Enterobacteriaceae have also emerged as potential opportunistic pathogens due to acquisition of virulence and antibiotic resistance and some, including E.

EFFECT OF MAIZE PARTICLE SIZE ON STARCH FERMENTABILITY AND LACTATION PERFORMANCE OF DAIRY COWS.

During the transition period (three weeks prior to three weeks after calving), dairy cows experience a period of considerable increase in energy demand coupled with a dramatic reduction in dry matter intake, leading to an unavoidable negative energy balance (NEB), which might cause metabolic and health problems, reduction in milk production as well as in reproductive performance. The site of starch digestion can modulate the negative effects associated with increased rumen starch fermentation such as feed intake, and the occurrence of problems encountered by transition cows.
