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.

THE SIGNIFICANCE OF PROTEOLYTIC PSYCHROTROPHS AS A CAUSE OF MILK FLOCCULATION / PROTEIN INSTABILITY

Discipline: quality; 

The report here is part of the Milk SA R & D programme to find solutions to the milk flocculation problem in the dairy industry. The investigation on the influence of psychrotrophic bacteria is by Prof Celia Hugo and postgraduate students at the University of the Free State.
