The percentage contents of fat, protein and mineral in eviscerated carcasses were determined at market age for a range of commercial table ducks. For fat determination the Soxhlet procedure using chloroform and freeze-dried, powdered samples appeared to be more effective than petroleum-ether extraction of wet material. The former procedure extracted approximately 7% more fat from carcasses containing 30 % fat. Percentage body water (W) was determined with a reproducibility of 0.99 and found to correlate closely with fat percentage (F) (r = -0.98): [image omitted] Correlations between economically important traits and carcass composition indicate that simple selection programmes based on the former will bring about undesirable correlated responses in the latter. |
