Resumen
El valor de materia seca (MS) es utilizado para indicar la cantidad de nutrientes (proteínas, lípidos, minerales y carbohidratos) contenidos en un alimento y que pueden ser aprovechados parcialmente por el animal para su mantenimiento y producción. Para la determinación de la materia seca se utiliza un método tradicional que consiste en el uso del horno de circulación forzada, este método conlleva un costo alto, difícil acceso por los productores y de duración de procesamiento de muestras lento, tardando entre 48 y 72 horas para la obtención del resultado final. Por lo que se han buscado diferentes alternativas más económicas para los productores, sin la necesidad de enviar muestras a laboratorios y ahorrando tiempo para la toma de decisiones. Por lo tanto, en el presente proyecto se evaluó la precisión de la freidora de aire en la determinación del porcentaje de materia seca de 13 distintos alimentos bases en las dietas para animales utilizando dos métodos: horno de circulación forzada (Tratamiento 1) y la freidora de aire (Tratamiento 2), con el objetivo de determinar la precisión y la exactitud del nuevo método. Los resultados demuestran que la freidora de aire, como método para determinar la materia seca en distintas especies forrajeras es una alternativa precisa, ya que presentó un coeficiente de determinación (R2) de 0.86, valor clasificado como alto. Los resultados obtenidos con la freidora aire en la determinación de la materia seca demostraron que existe una grande exactitud, ya que los datos de ambos métodos presentaron un comportamiento muy similar observando que la freidora de aire arrojó resultados de porcentaje de MS estadísticamente iguales que el horno de circulación forzada de acuerdo con la prueba t de Student en 92.3% de las muestras. Con esto podemos decir, que la freidora de aire tiene potencial para ser una alternativa para los productores y consultores a nivel de campo con el beneficio de ser de fácil acceso para los productores, mejor aprovechamiento del tiempo de trabajo, bajo costo y facilidad en su uso obteniendo resultados precisos y de alta exactitud.
The dry matter (DM) value is used to indicate the amount of nutrients (proteins, lipids, minerals, and carbohydrates) contained in food, which can be taken partially by the animal for its maintenance and production. For the determination of the dry matter the traditional method consists in the drying of the material using a forced circulation oven. This mechanism involves a high cost, difficult access for producers and low duration in the processing of the samples, taking from 48 to 72 hours getting the result. Since this situation, more economic alternatives have been seeked so producers are not obliged to send their samples to laboratories, saving time for decision taking. Thus, the present project evaluated the precision of an air frier in the determination of dry matter percentage for 13 different base foods in animal diets. Comparing the forced circulation oven method (treatment 19) and the air frier method (treatment 2), with the objective to state the precision and exactness of the new method (T2). The results show that the air frier, as a method of dry matter determiner in different grass species, is a precise alternative since it presented a determination coefficient (R2) of 0,86; value classified as high. The results obtained with the frier showed that it exists a big exactness. Both methods gave a similar behavior, air frier and the forced circulation oven of DM are statistically the same, according to the T test of student, in 92,3% of the samples. With this, it is possible to say that an air frier has the potential of being an alternative for producers and consultants in the fields with the benefit that, it involves less time, it is costs effective and its easy to use.
