BREEDING OBJECTIVES FOR HOLSTEIN CATTLE IN SOUTH AFRICA

Discipline: breeding;

 
A COST-BENEFIT MODEL COMPARING THE CALIFORNIA MILK CELL TEST AND MILK ELECTRICAL RESISTANCE TEST.

Discipline: mastitis; 
The effect of low-dose gamma irradiation and temperature on the microbiological and chemical changes during ripening of Cheddar cheese

Discipline: cheese; 

The effect of 4 kGy ionisation irradiation, combined with ripening temperatures at 8°C and 16°C on the ripening of Cheddar cheese was investigated. Changes in cheeses were monitored by sensory, microbiological, and chemical analyses.
Antimicrobial properties of lactic acid bacteria and yeast-LAB cultures isolated from traditional fermented milk against pathogenic Escherichia coli and Salmonella entiriditis strains.

Discipline: microbiology; 
Milk composition as technique to evaluate the relative bioavailability of a liquid rumen protected methionine source

Discipline: nutrition/feeding; 
NON-GENETIC FACTORS AFFECTING FERTILITY TRAITS IN SOUTH AFRICAN HOLSTEIN COWS

Discipline: reproduction;

 
Evaluation of genetic trends for traits of economic importance in South African Holstein cattle

Discipline: genetic evaluation; 
Winter and spring variation in milk yield and milk mineral composition on pasture in the south-eastern cape

 

Discipline: Composition; 
The live weight of replacement heifers on commercial dairy farms in comparison to breed guidelines.

Discipline: management;

Replacement heifer rearing is often neglected on dairy farms because for farmers the cost of rearing heifers apparently outweighs the advantage of well grown-out heifers. These advantages manifest in early conception and milk yield. To investigate trends in heifer raising, weights for age as a measure of heifer feeding programs were studied in the Western Cape.
