Summary: | The aim of this study was to analyse precocity behaviour over nine years in Hereford steers and their crosses, slaughtered with from zero to six teeth. Approximately 144,000 certified carcases in the Carne Pampa programme were analysed between 2010 and 2018. The increase in cold carcase weight per year was evaluated for three periods of the year: the hot season was defined as 26 December to 25 May, the autumn void was defined as 26 May to 25 July, and the cold season from 26 July to 25 December. To assess the behaviour of cold carcase weight over the years per season, the data were submitted to simple linear regression analysis. The average weights per season were compared by the mean value comparison test. The cold season had the highest mean carcase weight, with 239.1 kg, showing an annual increase of 6.45 kg. Analysing the behaviour of mean carcase weight by dentition, animals with zero teeth showed a greater weight increase over the years during the cold season as well as during the autumn void; during the hot season, animals slaughtered with two teeth showed the greater increase in weight. The category that showed the least increase in weight for all three seasons were animals slaughtered with six teeth. It was concluded that over the nine years, there was an increase in slaughter precocity in male cattle certified in the Carne Pampa programme.Keywords: Quality meat. Certification. Maturity.

Young steer.O objetivo deste estudo foi analisar o comportamento da precocidade ao longo de nove anos de novilhos da raça Hereford e suas cruzas abatidas com dentição de leite até seis dentes. Foram analisadas aproximadamente 144 mil carcaças certificadas no programa Carne Pampa, entre os anos 2010 e 2018. Avaliou-se o incremento no peso de carcaça fria por ano em três épocas do ano: a estação quente foi definida de 26 de dezembro a 25 de maio, o vazio de outono foi definido entre 26 de maio a 25 de julho e a estação fria de 26 de julho a 25 de dezembro. Para avaliar o comportamento dos pesos de carcaça fria ao longo dos anos por estação, os dados foram submetidos à análise de regressão linear simples. Os pesos médios por estação foram comparados por teste de comparação de médias. A época que apresentou maior peso médio de carcaça foi a estação fria, com 239,1 kg, que mostrou um incremento anual de 6,45 kg. Analisando o comportamento do peso médio de carcaça por dentição na estação fria, animais com dentição de leite apresentaram maior incremento de peso ao longo dos anos, na estação quente, animais abatidos com dois dentes apresentaram maior incremento de peso, assim como na estação vazio de outono. A categoria que apresentou menor incremento de peso nas três estações foram os animais abatidos com seis dentes. Concluiu-se que, ao longo dos nove anos, houve aumento na precocidade de abate em bovinos machos certificados no programa Carne Pampa.Palavras-chave: Carne de qualidade. Certificação. Maturidade.
