P.  aPerformance, carcass, and meat traits of locally adapted Brazilian cattle breeds under feedlot conditions.h[electronic resource]  c2023  aAbstract: Little is known about the performance, carcass, and meat traits of locally adapted cattle in Brazil. This study aimed to compare the growth, slaughter, and carcass traits as well as meat quality of two local breeds (Curraleiro Pé-Duro and Pantaneiro) with the Nelore breed. Fifteen 30-month-old steers of each breed were weighted (Curraleiro Pé-Duro = 264.80 kg; Nelore = 346.80 kg; Pantaneiro = 316.20 kg) and raised in a feedlot condition for 112 days, with measurements to assess growth and slaughter, visual and carcass and meat traits. Data were submitted to variance and multivariate analyses. Nelore and Curraleiro Pé-Duro had similar Gluteus medius depths. Pantaneiro and Curraleiro Pé-Duro were superior for leg compactness index (P &lt 0.05) and had higher eye muscle area than Nelore (P &lt 0.05). Although there was no difference in daily weight gain and slaughter weight between breeds, Curraleiro Pé-Duro had a lower initial weight (264.80 kg) when compared to Nelore (346.80 kg; P &lt 0.05). Nelore and Curraleiro Pé-Duro deposited more fat than Pantaneiro (P &lt 0.05), while Curraleiro Pé-Duro and Pantaneiro had more muscle than Nelore (P &lt 0.05), which also had more bone and a higher percentage of second-quality cuts (P &lt 0.05). Meat from Nelore also showed lower succulence than Pantaneiro (P &lt 0.05) and higher shear force than the other breeds (P &lt 0.05). Pantaneiro's meat had the most capacity to retain water (P &lt 0.05), lower shear force (P &lt 0.05), and was more succulent (P &lt 0.05) when compared to the other breeds. Multivariate analysis showed that Pantaneiro, Curraleiro Pé-Duro, and Nelore breeds can be considered distinct in growth, carcass, and meat traits, with the local breeds showing superior meat traits. The local breeds Curraleiro Pé-Duro and Pantaneiro presented characteristics similar or better to those of the Nelore, proving to be animals with great productive potential and generate high meat quality under feedlot conditions.  aCattle breeding  aMeat production  aBovinocultura  aNelore Brasileiro  aProdução de Carne  aCurraleiro Pé-Duro1 aFIORAVANTI, M.
