摘要

As grazed grass is considerably cheaper than conserved forages and concentrate feeds in temperate climates(Finneran et al., 2012), finishing cattle from pasture is less costly. Compared to steers, bulls have biological advantages interms of growth rate and feed efficiency (O'Riordan et al., 2011). Suckler bull beef production usually involves a postweaningindoor feeding period based on conserved forage supplemented with concentrates or concentrates offered adlibitum (O'Riordan et al., 2011). Within these production systems achieving a commercially acceptable carcass fat score (6,scale 1-15) is a primary market requirement. There is relatively little published information comparing the performance ofpasture-finished bulls and steers. Therefore, the objective of this study was to evaluate the growth, carcass and selectedmeat quality traits of spring-born Aberdeen Angus-sired suckler bulls and steers finished at pasture at 19 months of age.
