TRITICALE IN DIETS FOR BROILERSABSTRACT -A study was carried out to determine the best replacement level of corn by triticale in diets for broilers. A total of 1,560 one-day old birds, both male and female, were used in the study from 1 to 42 days of age. The experimental design was in random blocks with five treatments: 0, 25, 50, 75% of replacement of corn by triticale, and a fifth diet containing basically triticale and soybean meal. There were 12 replicates per treatment, six with males and six with females. All diets were isocaloric and isoproteic. There was an effect of sex (P<0.05) for all studied variables, except feed conversion during the first phase of the experiment. Males showed better performance than females. The interaction between sex and treatment was not significant (P>0.05). According to the results, it is possible to replace up to 75% of corn by triticale, without negatively affect the performance of broilers. The use of triticale will be economically possible for broiler of both sexes, when its cost represents 63, 46 and 45% of price of corn, for substitution levels of 25, 50 and 75%, respectively. Although showing worst performance, total substitution of corn by triticale is advantajous if triticale price is up till 42% corn price.Index terms: performance, alternative feedstuffs, nutritive value. INTRODUÇÃOO uso de alimentos alternativos é importante quando se busca a redução de custos na produção de frangos de corte. O triticale é um cereal resultante do cruzamento do trigo e centeio. Os resultados publicados na literatura sobre esse cereal são muitas vezes contraditórios. O que provavelmente se deve a grande variação em sua composição.

Tetrazolium test for evaluating triticale seed viability

“…Triticale (x.Triticosecale Wittmack), a hybrid winter cereal resulting from crossing wheat (Triticum aestivum) and rye (Secale cereale), has high commercial potential in some areas of Southern Brazil where it is principally used as an animal feedstuff and energy source in the period between maize (Zea mays) harvests (Brum et al, 1998), although it is also used as a feedstuff in the production of biscuits (cookies), breads and other dietary products for human consumption.…”

Substituição do milho pelo triticale na alimentação de tilápias-do-nilo

“…Em frangos de corte, é possível substituir 75,0% do milho pelo triticale sem prejudicar o desempenho produtivo, o que indica que o preço do triticale precisaria ser 63,0; 45,0 e 43,0% do preço do milho para compensar a substituição de 25,0; 50,0 e 75,0%, respectivamente (De Brum et al, 2000).…”
