BIOFILM FORMATION AND ANTIMICROBIAL RESISTANCE PATTERNS OF STREPTOCOCCUS UBERIS SPECIES. | Discipline: mastitis; Keywords: Streptococcus uberis, SCC, clinical mastitis, biofilm, AMR, antimicrobials, susceptibility. |
|
PASTURE YIELD AND ENVIRONMENTAL EFFECT OF NITROGEN FERTILIZATION. | Discipline: pasture, grazing; Keywords: Pasture yield optimization, nitrogen use efficiency; nitrogen fertilization, farm-N-balance, carbon footprint. |
|
MASTITIS RESEARCH IN SOUTH AFRICA: THE COST TO THE DAIRY FARMER. | Discipline: mastitis; Keywords: economic loss, SCC, TMR and pasture-based systems, failure cost, preventive cost. Mastitis results in large economic loss to both farmer and processor. In addition it has welfare implications for the cow and antimicrobial resistance concerns. Therefore, describing and analysing the measures used to prevent the disease and to minimize the losses remain important. For example, somatic cell count (SCC) directly affects revenue from the sale of milk and in one of the investigations the revenue loss was studied. |
|
AN ANALYSIS OF THE GLOBAL RELEVANCE AND IMPACT OF CATTLE. | Discipline: management; economics; Keywords: cattle, world trade, methane emission, photosynthesis, carbon sequestration, grazing capacity, cover crops |
|
A FLEXIBLE MODEL TO ESTIMATE GHG TOGETHER WITH FINANCIAL RESULTS | Discipline: environment; Keywords: Greenhouse gas, system dynamic model, methane, FPCM, feed sources, cow’s physiological processes. |
|
MASTITIS RESEARCH IN SA: CONTROL THROUGH SCC AND OTHER MEANS. | Discipline: mastitis; Keywords: SCC, herd testing, rotary parlour, antimicrobial sensitivity, systematic extension and training, summer rise in SCC, year effect. |
