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.

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.
