The incidence of human coronary heart disease has been correlated with the serum cholesterol level and a high consumption of saturated fat. Furthermore the cholesterol level can be raised by shorter chain fatty acids (Rose, 1990). It was therefore interesting to compare breeds extreme in terms of fatness. The adipose tissue proportion of the Belgian Blue double muscled type (BBDM) is low while that in Holstein is high, the Belgian Blue dual purpose (BBDP) type being intermediate. The present experiment was designed to investigate how large difference in degree of fatness can be associated with differences in fatty acid composition.Four bulls of the 3 breeds were used in a fattening trial. Their initial weight was 340 kg. Biopsy samples were taken from the Longitimus Dorsi (LD) at weeks 5 and 16 of the fattening period. They were slaughtered after 145 days. The 7-8-9 ribs and perirenal fat (PR) were removed at slaughter. Intramuscular (M) and intermuscular (IM) fats of the LD were obtained after dissection of the 7-8-9 ribs. |
