RESUMO -Dois experimentos foram realizados para avaliar o desempenho e a digestibilidade dos nutrientes (matéria seca, matéria orgânica e energia bruta e o coeficiente de metabolização da energia bruta) das rações contendo triticale. Os tratamentos consistiram de uma ração à base de milho e farelo de soja e outras três com 33, 66 e 100% de substituição do milho pelo triticale. No primeiro experimento, 144 suínos na fase de crescimento (25,27 -59,60 kg PV) foram distribuídos em delineamento de blocos casualizados, com quatro tratamentos, quatro repetições e nove animais (cinco fêmeas e quatro machos) por unidade experimental. No segundo experimento, 12 suínos machos, com peso médio inicial de 32,14 kg, foram alojados em gaiolas de metabolismo e distribuídos em delineamento experimental de blocos casualizados, com quatro tratamentos e três repetições, sendo o animal a unidade experimental. O método da coleta total de fezes e urina foi usado neste experimento. A inclusão de níveis crescentes de triticale não influiu no ganho de peso médio e no consumo de ração, porém melhorou linearmente a conversão alimentar e reduziu linearmente o custo da ração por quilograma de peso vivo ganho. A inclusão de triticale reduziu linearmente o coeficiente de digestibilidade da energia bruta das rações experimentais.Palavras-chave: desempenho, digestibilidade, suínos crescimento, triticale Use of Triticale (Triticum turgidosecale) in Swine Feeding during the Growing Phase (25 -60 kg)ABSTRACT -Two experiments were conducted to evaluate the performance and nutrient digestibility (dry matter, organic matter and gross energy, and the metabolization coefficient of the gross energy) of triticale based diets. The treatments consisted in a corn and soybean meal based diet and three other ones with corn 33, 66 and 100% of substitution of corn by triticale. In the first experiment, 144 pigs in the growing phase (25.27-59.60 kg LW) were allotted to a randomized block design, with four treatments, four replicates and nine animals (five females and four males) per experimental unit. In the second experiment, twelve barrows averaging 32.14 kg LW were placed in metabolic cages and allotted to a randomized block design, with four treatments and three replicates,and one animal on experimental unit. The method of total feces and urine collection was used in this experiment. The inclusion of crescent levels of triticale did not affect the average weight gain and feed intake, however it linearly improved the feed: gain ratio and linearly reduced the diet cost per kilogram of live weight gain. The levels of triticale linearly decreased the gross energy digestibility coefficient of the experimental diets.
