Niveles de Sustitución de un nutriente de origen energético arroz partido (oryza sativa) por maíz (zea mays) en la alimentación de cerdos en la etapa de crecimiento y engorde

To carry out this research, it was based on the replacement of a nutrient of energy origin, broken rice (oryza sativa) with corn (zea mays) in the feeding of pigs in the growth and fattening stage. For the research, an experimental group of ten pigs was used, where they are divided into five groups assigned to each treatment, the first group was assigned as a control treatment where it only received a diet based on balanced feed and water, entering the experiment with an average weight of 26 kg and finishing it with an average weight of 58.5 kg, having a profitability of 0.3 cents of each investment dollar; The second group was assigned a diet based on the inclusion of 25% broken rice, 75% corn and water; entering the experiment with an average weight of 30.5kg and ending it with a weight of 68.5, generating a profitability of 0.7 cents; The third group was assigned a diet based on 50% broken rice, 50% corn and water; entering the research with an average weight of 34.5 kg and ending it with 70.5 kg, generating a profit of 0.15 cents; The fourth group was assigned a diet based on 75% broken rice, 25% corn and water and finally the fifth group was assigned a diet based on 100% broken rice plus water; These last two treatments obtained negative values, regarding the benefit/cost analysis. A completely randomized design was used, all the variables to be evaluated were recorded week by week for two months, since this research focuses on the use of these energy nutrients in the growth and fattening stage in pigs; For the management of the test, the pigs were fed twice a day and had the availability to drink water freely. Regarding the fulfillment of the general objective, it was observed that in the substitution of broken rice for corn, the greater the inclusion of rice, the lower the profitability of the research.

Para la realización de esta investigación se basó en la sustitución de un nutriente de origen energético arroz partido (oryza sativa) por maíz (zea mays) en la alimentación de cerdos en la etapa de crecimiento y engorde. Para la investigación se utilizó un grupo experimental de 10 cerdos, donde se dividen en cinco grupos asignados a cada tratamiento, el primer grupo fue asignado como tratamiento testigo donde solo recibió una dieta a base de balanceado y agua, ingresando al experimento con un peso promedio de 26 kg y terminándolo con un promedio de peso de 58,5 kg, teniendo una rentabilidad de 0,3 centavos de cada dólar de inversión; el segundo grupo se le asignó una dieta a base de la inclusión de 25% de arroz partido, 75% de maíz y agua; ingresando al experimento con un peso promedio de 30,5kg y terminándolo con un peso de 68,5, generando una rentabilidad de 0,7 centavos; el tercer grupo se le asignó una dieta a base de 50% de arroz partido, 50% de maíz y agua; ingresando a la investigación con un peso promedio de 34,5 kg y finalizándolo con 70,5 kg, generando una ganancia de 0,15 centavos de dólar; el cuarto grupo se le asignó una dieta a base de 75% de arroz partido, 25% de maíz y agua y por último el quinto grupo se le asignó una dieta a base de 100% de arroz partido más el agua; estos dos últimos tratamientos obtuvieron valores negativos, en cuanto al análisis de beneficio/costo. Se utilizó un diseño completamente al azar, todas las variables a evaluar fueron registradas semana a semana durante dos meses, ya que esta investigación se enfoca en la utilización de estos nutrientes energéticos en la etapa de crecimiento y engorde en cerdos; para el manejo del ensayo a los cerdos se les alimento dos veces al día y teniendo la disponibilidad de beber agua a libertad. En cuanto al cumplimiento del objetivo general, se pudo observar que en la sustitución de arroz partido por maíz, en cuanto mayor fue la inclusión del arroz menor fue la rentabilidad de la investigación.
