“…At the same time, there was intense scientific research that measured and expanded the knowledge on carcass and beef traits, such as the studies by Müller & Primo (1986), Restle et al (1999a), Restle et al (1999b), Perotto et al (2000), , Restle & Vaz (2003), and Paulino et al (2005).…”

-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%

“…Além de a terminação ser mais eficiente em animais mais jovens (RESTLE et al, 1999), estratégias de alimentação suplementar na fase de crescimento, significam maior peso de entrada no confinamento resultando em menor tempo na terminação. Dessa forma, o crescimento corporal e o nível do ganho em peso do animal antes dos 12 meses, têm reflexo em características importantes da carcaça e da carne de bovinos de corte (RESTLE et al, 1999).…”

“…Another aspect related to meat fat is tenderness, as intramuscular fat favors muscle fiber by destructuring and lubricating the bolus during chewing, increasing the perception of tenderness (Berg & Butterfield, 1976;Wood, 1990;Restle et al, 1999;Restle et al, 2001;Rodrigues & Andrade, 2004). However, genetic selection for tenderness and lower market age, as a development of the genetic selection for weight gain and precocity (Costa et al, 2002;Bonilha et al, 2007), has produced young steers with high meat tenderness, which was produced before by animals with high finishing degree (Wood, 1990).…”

-The objective of this study was to evaluate total and individual meat yield of boneless cuts, retail cuts, descarded trimmings and carcass bones of 38 Braford castrated steers, slaughtered at 22 months of age after feedlot finishing.Carcasses were classified in three ranks according to fat coverage: even fat coverage over the carcass, with fat thickness of approximately 6-8 mm on the 12 th rib; animals with uneven fat cover, with fat thickness of 3-5 mm and steers with insufficient fat coverage over the carcass, with fat thickness of 1-2 mm. Shrinkage losses decreased as fat coverage increased, and it was 2.57, 2.22, and 1.96%, respectively, for insufficient, uneven, and even fat coverage whereas flank yield increased, reaching values of 13.04, 13.47 and 14.36%. Boneless yield was the highest in carcasses with insufficient fat coverage (78.70%) when compared to even fat coverage (77.62%), which is a result of the lowest trimming percentage, which increased according to coverage fat (4.40; 5.14 and 6.01%, respectively for carcass with insufficient fat coverage, uneven fat coverage and even fat coverage). Back rib and short rib yields were the greatest in carcasses with the largest fat thickness, whereas percentage of silverside and topside were the greatest in carcass with insufficient fat coverage compared to the ones with even fat coverage. Braford castrated steers can be slaughtered with the smallest fat coverage because the low fat coverage does not affect negatively yield of secondary cuts. Increase in coverage fat reduces shrinkage losses mainly in cuts submitted to little fat trimming.
