Abstract

Estimation of slaughtering by-products arising from the Maltese rabbit industry indicated that this product could have a significant contribution to the economy if collected and rendered into a meal to be used as a feed ingredient. The effects of a processed foodwaste product, at 0, 10, 20, or 30% of the diet, on growth performance, carcass composition and meat quality of 64 finishing pigs (50 - 110kg) was determined. Growth performance of pigs on the control diet was depressed due to lack of salt (NaCl) in the diet. There were no significant differences (P > 0.05) among test diets on growth performance (0.95kg/day). Despite increasing fat content in the diets, there was no difference in the amount of fat in the dissected primals (shoulder, ham and loin), however, a significant gender effect was noted. Dissection of belly primals showed that accuracy of percent belly lean prediction equations is significantly increased with the inclusion of gender effects, and that percent belly fat values have not changed over the last 25 years. Evaluation of processing conditions on the feeding value of processed foodwaste, confirmed that cooking beyond 30 minutes at 100\sp∘C significantly reduces feeding quality.
