Issue Date: | Nov-2009 | Publisher: | Elsevier | Citation: | Meat Science 83(3): 511-516 (2009) | Abstract: | Twenty-seven lambs were used to investigate the effects of the inclusion of 4% hydrogenated palm oil (HPO) or sunflower oil (SFO) in the concentrate on animal performance, carcass and meat quality and fat characteristics and fatty acid composition. Animals (16.2 +/- 0.27 kg initial weight) were fed concentrate (Control, HPO or SFO) and barley straw ad libitum and slaughtered at 25 kg. SFO lambs tended to eat less concentrate than HPO animals (P < 0.10). Neither HPO nor SFO affected any of the carcass characteristics studied, meat pH and meat and fat colour (P > 0.05). SFO decreased proportions of C16:0, C18:1 cis-11 and C18:3 (P < 0.05) and increased C18:1 trans (P < 0.001) and C18:2/C18:3 ratio (P < 0.05). Atherogenicity index was lower (P < 0.05) when SFO was included in the concentrate. HPO did not affected and SFO improved fatty acid composition of fattening lambs without affecting animal performance. | Description: | 6 pages, 7 tables. | Publisher version (URL): | http://dx.doi.org/10.1016/j.meatsci.2009.06.035 | URI: | http://hdl.handle.net/10261/19585 | DOI: | 10.1016/j.meatsci.2009.06.035 | ISSN: | 0309-1740 |
