PUBLIC CONCERNS ABOUT CERTAIN MANAGEMENT PROCEDURES AND ADDITIVES IN DAIRY PRODUCTION: ARE THEY JUSTIFIED? Food Safety and Quality

Probably under activist pressure and uninformed public perceptions, certain milk processors and retailers began to make label claims describing specific production systems and management procedures on dairy farms, thereby confusing consumers by creating the impression that milk produced under specific conditions is healthier or safer than other milk. Claims include the practice of organic farming, the non-use of genetically modified organisms (GMOs), pesticides and ionophore antibiotics and the marketing of recombinant bovine somatotropin (r-bST) free milk.

With my regular column of DAIRY R & D IN SA on the website, I from time to time will give feedback on research projects which Milk SA funds. This will deal with progress and plans for the next year or phase. This project by the researchers at UKZN is in its first year of implementation and is envisaged to continue to at least 2019.

BLOOD PROTEIN CONCENTRATIONS IN SMALLHOLDER JERSEY COWS.

Discipline: nutrition/feeding; 

Smallholder production systems often lack feed sources with sufficient nutrients to support milk production. Of particular significance is the level of protein in the diets during early lactation. The authors referenced below therefore investigated a scenario of this kind by measuring serum protein concentration of pre-calving and early lactation Jersey cows kept under semi-intensive management on smallholder farms.
