Development of an energy-protein for animal food based crop residues pear (Pyrus communis)

Pear (Pyrus communis) is a fruit from the species of deciduous, widely consumed worldwide for its high quality energy. However, pear itself does not provide the amount of protein required for cattle feeding, so alternatives to improve its nutritional quality have been studied. On these grounds, the objective of this study was to evaluate the parameters of solid state fermentation, and compositional energy value of a protein food based on pears (Pyrus communis) with apparent physical damage. A completely random design was used to evaluate three treatments; these correspond to percentages of inclusion of calcium carbonate (0.25, 0.50, 0.75) formulation based on already established (40% pear, 25% rice flour, 25% wheat bran and 10% urea), the parameters evaluated were: pH, ashes (CZ), crude protein (CP) and crude fiber (CF), and they were recorded at 0, 24, 48 and 72 hours. As a result, it was found that the pH dropped gradually for each treatment and at each sampling period; however, there were no significant differences. The lower value at the end of the process is recorded T2 (0.25) with 4.66, followed by T3 (0.50) with 4.50, the ash reached values of up to 6% with T3, and T2 (0.50) reached the highest percentages in fiber and crude protein. Finally, ecreasing the fermentation variables ensures a food with no presence of undesirable microorganisms and stable over time. La pera (Pyrus communis) es una fruta perteneciente a la especie de los caducifolios, ampliamente consumida a nivel mundial por su alta calidad energética. Sin embargo, la pera por sí sola no aporta la cantidad proteica requerida para la alimentación en los bovinos, por lo que se han venido estudiando alternativas que mejoren su calidad nutricional. En este sentido, el objetivo de este trabajo fue evaluar los parámetros de fermentación en estado sólido y valor composicional de un alimento energético-proteico basado en pera (Pyrus communis) con daño físico aparente. Se utilizó un diseño completamente al azar para evaluar tres tratamientos, estos correspondieron a porcentajes de inclusión de carbonato de calcio (0,25, 0,50,0,75) sobre la base de formulación ya establecida.
