Carcass and meat quality of young Angus steers with different growth potential finished exclusively grass-fed or corn supplemented

Growth Performance, Carcass and Meat Traits of Autochthonous Arouquesa Weaners Raised on Traditional and Improved Feeding Systems

“…The CW and lumbar measurements were not different ( p > 0.05) between groups. These results were not expected since most of the studies reported higher carcass weights when increasing the concentrate levels [ 28 , 42 ]. The muscle area and subcutaneous fat tend to be higher in grass-fed animals when compared with supplemented animals, likely due to higher efficiency in the conversion of feed into weight gain [ 42 ].…”

The Arouquesa production system is quite different from most standard beef production systems, as the animals are weaned and slaughtered at 9 months.…”
