Slaughtering cattle at lighter weights to produce leaner meat might be expected to improve efficiency of production. An earlier experiment with Hereford x Friesian steers (Thomas, Kay, Hamilton and Fisher, 1987) showed no significant effect on feed efficiency when cattle were slaughtered at three different EC fat classes. An experiment was subsequently carried out to examine the effect on performance, carcass characteristics and meat quality of two breeds of cattle slaughtered at three different levels of fatness. In this experiment backfat depth was used as the criterion for slaughter.Thirty Hereford x Friesian/Holstein steers (initial weight 326 kg) and 30 Limousin x Holstein/Friesian steers (initial weight 340 kg) were used in the experiment.

Grazing Swan geese (Anser cygnoides) have good meat quality but grow slowly. This study aimed to study whether supplemental feeding could improve growth performance of grazing Swan geese and investigate a suitable dietary metabolizable energy (ME) level of supplemental diet for grazing Swan geese. Naturalized healthy male Swan geese (n = 144; 42 ± 2.0 days and 1.21 ± 0.17 kg) were randomly allocated into 4 groups and grazed on pasture alone (control, CON) or offered supplemental diets with ME of 9.5, 11.5, or 13.5 MJ/kg of DM after grazing. Growth performance and body-size measurements (including bone development) were lower (p < 0.05) in CON versus supplemented geese, as well as slaughter measurements on days 28 and 56. The DM intake linearly decreased (p < 0.01) with increasing dietary ME from day 29 to 56. Slaughter, semi-eviscerated, eviscerated, and thigh muscle yield linearly (p < 0.01) decreased with increasing dietary ME on day 56. Lightness (L*) and yellowness (b*) for breast and thigh muscle on days 28 and 56, and breast muscle shear force on day 56, were lower (p < 0.01) in supplemented versus CON geese. In conclusion, supplemental feeding improved growth performance and carcass characteristics of grazing Swan geese, and supplemental feed with ME of 9.5 MJ/kg of DM could be offered to improve growth and meat quality of grazing Swan geese.
