“…The hindquarter yielded 70.91% prepared meat cuts, 19.41% bones, and 9.68% total trimmings (4.06% edible + 5.62% discarded trimmings). This allowed us to compared our data with those obtained by Tarouco et al (2007), who deboned the hindquarter of 102 Braford animals, which, however, were younger (12 months of age) and lighter (158.25 kg carcass) than the steers used in the present experiment, and obtained 68.53% prepared cut yield, 20.76% bones, and 10.82% total trimmings, which were very similar to our results.…”

“…In the present study, total average bone yield was 17.65% (Table 8), not taking into consideration rib bones, as the rib cuts were prepared with bone in. Summing the 1.96% rib bone yield obtained by (Osório et al, 1995;Junqueira et al, 1998;Ledic et al, 2000;Coutinho Filho et al, 2006;Bonilha et al, 2007;Tarouco et al, 2007) found lower percentages of edible cuts, and higher percentages of bone than those that reported the method proposed by Hankins & Howe (1946) (Perotto et al, 2000;Feijó et al, 2001;Vaz & Restle, 2005;Kuss et al, 2005;Canesin et al, 2006). The studies using the direct assessment method for deboning obtained 19.08% average bone yield, whereas those applying the HH method achieved 16.85%, resulting in a 3.23% difference.…”

-The experiment evaluated the meat yield of prepared beef cuts, bone and trimmings of steer and culled cow carcasses. Culled 72-month-old Braford cows, 496 kg live weight and 36-month-old steers, 494 kg live weight were used, all from the same herd and finished on ryegrass pasture. A randomized complete design, with two treatments and 15 replications, was used. Hot carcass weight was lower for cows (248 kg) than for steers (263 kg). Steer carcasses presented better conformation, lower chilling loss, shorter (128.6 vs. 137.7 cm), with longer and thicker limbs compared to cows and similar fat finishing. Steer carcasses showed, compared to cow carcasses, always in the same order, similar side cut yield (13.5 vs. 13.4%), higher forequarter yield (38.4 vs. 37.2%), and lower hindquarter yield (48.1 vs. 48.9%), resulting lower yields of the sub-primal cuts full rump and sirloin, lower rump UK trim, rump tail and striploin. Steer and cow carcasses were similar in total yield of prepared meat cuts (77.8 vs. 77.6%), discarded bone (17.4 vs. 17.9%), discarded trimmings (4.54 vs. 4.09%), and losses inherent to the deboning process (0.34 vs. 0.34%). The results showed that cow carcasses are longer, have shorter and thinner limbs, have higher hindquarter and lower of forequarter yields, but the total yield of prepared meat cuts were similar between cow and steer carcasses.Key Words: Braford, commercial cuts, deboning, hindquarter, primal cuts, retail cuts Rendimento de cortes preparados de carcaças de vacas e de novilhosRESUMO -Avaliaram-se os rendimentos de cortes cárneos preparados, de osso e de retalho descartado das carcaças de animais de novilhos e vacas de descarte. Utilizaram-se 15 vacas de 72 meses com peso vivo de 496 kg e 15 novilhos de 36 meses com peso vivo de 494 kg, todos da raça Braford e de mesmo rebanho, terminados em pastagem de azevém.O experimento foi realizado em delineamento inteiramente casualizado, com duas categorias animais, cada uma com 15 repetições. O peso de carcaça quente das vacas de descarte (248 kg) foi inferior ao dos novilhos (263 kg). As carcaças dos novilhos apresentaram melhor conformação, com menor quebra no resfriamento, e foram mais curtas (128,6 vs 137,7 cm), com membros mais longos e espessos em comparação às carcaças das vacas. A porcentagem de gordura de cobertura foi similar entre as categorias. Em comparação às vacas de descarte, os novilhos apresentaram rendimento similar de costilhar (13,5 vs 13,4%), maior de dianteiro (38,4 vs 37,2%) e menor de serrote (48.1 vs 48.9%). Novilhos apresentaram menor rendimento de alcatra e lombo e menor rendimento de miolo da alcatra, maminha e contrafilé. As carcaças de vacas e de novilhos são similares quanto aos rendimentos totais de cortes cárneos preparados (77,8 vs 77,6%), osso descartado (17,5 vs 17,9%), retalho descartado (4,54 vs 4,09%) e perdas inerentes (0,34 vs 0,34%). Vacas têm carcaça mais comprida, membros mais curtos e finos, maior rendimento de serrote, menor de dianteiro e similar de costilhar, mas o rendimento total d...

“…Further research studies should be carried out on this subject as the frame of cattle has changed in the last few decades. When the equations In the studies by Osório et al (1995), Junqueira et al (1998), Ledic et al (2000), Coutinho Filho et al (2006, Bonilha et al (2007), and Tarouco et al (2007), the authors used the direct deboning method, and found lower edible cuts percentages and higher bone percentages than those reported in most of the articles using the HH section proposed by Hankins & Howe (1946).…”

“…To understand which biotypes and carcass standards result in higher cuts yield became the objective of researchers such as Bonilha et al (2007) and Tarouco et al (2007), in order to determine which of those biotypes and carcass should get premiums for productivity and quality.…”

-The experiment evaluated total and individual yield of commercial cuts, bones, and trimmings of carcasses from 38 Braford steers at 22 months of age finished in a feedlot. Carcasses were ranked according to three conformation classes (good minus = score 10; good = score 11; good plus = score 12), and three weight classes (heavy = 229.4 kg, intermediate = 205.0 kg, and light = 184.0 kg, ranging from 222.9 to 250.4, 201.5 to 209.0, and 170.0 to 190.3 kg, respectively). Carcass cold shrinkage was not affected by conformation, but it was significantly lower in heavy (1.83%) than in intermediate (2.53%) and in light carcasses (2.30%), which were not different among each other. Carcass flank percentage was not affected by conformation, but it was significantly higher in heavy (13.93%) and intermediate carcasses (13.87%) as compared to light carcasses (13.07%). Deboned beef cuts (78.08%) of carcasses of steers, bone (16.57%), and trimmings (5.23%) yields and losses due to deboning (0.12%) were not significantly affected by carcass weight. However, when they were evaluated according to conformation classes, those with better conformation showed higher meat cut yield (78.75 vs 77.92 and 77.29%). Conformation affects meat cut yield of carcasses of young steers while carcass weight does not show this characteristic.Key Words: Braford, commercial cuts, deboning, edible portion, pistol, primal cuts Rendimento de cortes cárneos de carcaças de novilhos classificadas de acordo com a conformação e o peso de carcaçaRESUMO -Avaliaram-se os rendimentos cárneos total e individual de cortes comerciais, de osso e de retalho de carcaças de 38 novilhos Braford com 22 meses de idade terminados em confinamento. As carcaças foram classificadas de acordo com três classes de conformação (boa menos = 10 pontos; boa = 11 pontos; e boa mais = 12 pontos) e três classes de peso (pesadas = 229,40 kg; medianas = 205,04 kg; e leves = 184,00 kg com variação, 222,9 a 250,4; 201,5 a 209,0; e 170,0 a 190,3 kg, respectivamente). A quebra no resfriamento não foi influenciada pela conformação, mas foi significativamente menor nas carcaças pesadas (1,83%) em comparação às medianas (2,53%) e leves (2,30%), que não diferiram entre si. A participação relativa da ponta-de-agulha não foi afetada pela conformação, mas foi significativamente maior nas carcaças pesadas (13,93%) e medianas (13,87%) em relação às leves (13,07%
