Summary: | A study was conducted to evaluate the use of macro ingredients as markers of the quality of mixed feeds. Were used: popcorn grain, sorghum, millet, rice colored and purple corn grinded (0.5% added to the diet, substituting grind corn) and coarse limestone sieved through sieve nº 10 ABNT with 2 mm (added in 0.5% in the diet, substituting finely ground limestone). Microtracer F-Red was used as a method of reference. It was used a Y-type mixer (capacity of 5,000 cm3), and produced 1 kg of feed per repetition. It was adopted six mixing times (10 seconds, 1, 6, 11, 16 and 21 minutes) and five particle size of corn (386, 513, 610, 731 and 839 ?m), amounting 30 treatments with three repetitions for each treatment. Where collected 12 samples, for each replicate, to measurement of the markers and determination of the coefficient of variation (CV). A quadratic effect with minimum point for the CV was observed for all markers with the increasing of the mixing time. There was no effect of the particle size of corn for the coefficients of variation of coarse limestone and millet. There was a quadratic response of the particle size of corn for the coefficients of variation of purple corn and popcorn grain and linear effect for the colored rice, sorghum and reference method. The particle size of corn changed the time needed to reduce the CV of the markers: colored rice, milled purple corn, popcorn, sorghum and microtracer. The use of alternative markers has shown that it is a promising tool for the determination of the optimum mixing time, especially millet and limestone, that showed the highest correlations with the reference method. |

Foram utilizados: milho pipoca, sorgo, milheto, arroz colorido, milho roxo moído (adicionados em 0,5% na ração, em substituição ao milho moído) e o calcário grosso peneirado em peneira ABNT nº10 com dois milímetros de diâmetro das malhas (adicionado em 0,5% na ração, em substituição ao calcário finamente moído). Como método referência utilizou-se microtracer F-Red. Foi utilizado um misturador tipo Y (capacidade de 5.000 cm3) e fabricado 1 kg de ração para cada repetição. Foram utilizados seis tempos de mistura (10 segundos; 1; 6; 11; 16 e 21 minutos) e cinco diâmetros geométricos médios do milho (386; 513; 610; 731 e 839 ?m) totalizando 30 tratamentos, com três repetições por tratamento. Foram coletadas 12 amostras, para cada unidade experimental, para a contagem dos indicadores e determinação do coeficiente de variação (CV). Houve efeito quadrático com ponto de mínimo para os CV de todos os indicadores com o aumento do tempo de mistura. Não houve efeito do diâmetro geométrico médio do milho para os CV do calcário grosso e milheto. Houve efeito quadrático do diâmetro geométrico médio do milho para os CV do milho roxo e milho pipoca e efeito linear para o arroz colorido, sorgo e para o método referência. A granulometria do milho alterou o tempo necessário para reduzir o CV dos indicadores: arroz colorido, milho roxo moído, milho pipoca, sorgo e microtracer. A utilização de indicadores alternativos se mostrou promissora como ferramenta para determinação dos tempos ideais de mistura, com destaque para o milheto e o calcário, pois apresentaram as maiores correlações com o método referência.UEL2014-06-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1309910.5433/1679-0359.2014v35n3p1463Semina: Ciências Agrárias; Vol. 35 No. 3 (2014); 1463-1474Semina: Ciências Agrárias; v. 35 n. 3 (2014); 1463-14741679-03591676-546Xreponame:Semina.
