Resumen
Una problemática mundial es el crecimiento de demanda alimenticia para el ser humano, siempre intentando utilizar los recursos de la mejor manera posible sin afectar la salud mundial. Bajo este objetivo se interpone la utilización de materiales de residuos para producir alimentos para el ser humano, uno de estos residuos que pueden aprovecharse son los excrementos de una especie para alimentar a otra. Este proyecto se diseñó para evaluar el efecto del uso de cerdaza en combinación con alimento concentrado convencional en gallinas ponedoras sobre la cantidad, tamaño y peso de huevos. En este proyecto, se utilizaron 15 gallinas ponedoras distribuidas al azar en tres tratamientos donde cada uno contuvo 5 gallinas, el tratamiento 1 recibió 100% de concentrado, el tratamiento 2 recibió 50% de cerdaza y el tratamiento 3 recibió 25 % de cerdaza. Durante el proyecto, los datos fueron tomando diariamente y las variables medidas fueron cantidad de huevo, peso y tamaño, para este último se tomó el diámetro longitudinal y el diámetro ecuatorial. Los datos se sometieron a análisis de variancia con un nivel de significancia de 5%, usando R-Studio. De acuerdo con los resultados; la variable cantidad de huevo en la semana 1 y la semana 2, hubo diferencia significativa (p < 0,05) a favor del T2, pero de la semana 3 hasta la semana 9 no hubo diferencia significativa entre los tratamientos (P > 0,05). Para la variable peso de huevo, desde la semana 1 hasta la semana 5 hubo diferencia significativa a favor del tratamiento 3 (P < 0,05), desde la semana 6 hasta la semana 9 no hubo diferencia significativa entre los tratamientos (P > 0,05). Para la variable diámetro longitudinal, en la semana 1 y la semana 2 hubo diferencia significativa (p < 0,05) a favor del T2, de la semana 3 hasta la semana 9 no hubo diferencia significativa entre los tratamientos (P > 0,05). Igual los datos de diámetro ecuatorial de huevos hubo diferencia significativa a favor de T3. Según los resultados de los análisis estadísticos, se concluyó que el T3 fue el mejor en peso y tamaño de huevo mientras que T2 fue el mejor en cantidad de huevo.
Food demand for humans is a rising global problem, and there are always attempts to use resources in the best possible way without affecting the world’s condition. Under this objective, the need to use waste products to be part of food production for humans stands out, and one of these wastes that can be used is the excrement of one species to feed another. This project was designed to assess the quantity and size of eggs with the use of pig slurry in combination with conventional concentrated feed from laying hens. To carry out the project, 15 laying hens were used randomly and distributed in three treatments, where each contained five hens: Treatment 1 received 100 % concentrate, Treatment 2 received 50 % pig slurry, and Treatment 3 received 25 % pig slurry. During the project, data was taken daily for each and the variables measured were egg quantity, weight and size. The egg size was taken using the longitudinal diameter and the equatorial diameter. The data of the variables was subjected to analysis of variance with a level of significance of 5 % with the R-Studio program. The results obtained indicated that for the variable of egg quantity, in week 1 and week 2, there was a significant difference (P< 0,05) in favor of T2. However, from week three to week nine, there was no significant difference between the treatments (P >0,05). For the variable of egg weight, from week 1 to week 5, there was a significant difference in favor of T3 (p < 0,05). However, from week 6 to week 9, there was no significant difference between the treatments (P>0.05). For the longitudinal diameter variable, in week 1 and week, there was a significant difference (P<0,05) in favor of Treatment 2. However, from week 3 to week 9, there was no significant difference between treatments (P>0,05). For the equatorial diameter of the eggs, there was a significant difference in favor of T3, there were no significant differences between them after taking into account the results of the statistical analyses, Thus, it was concluded that T3 was the best treatment in egg weight and size while T2 was the best in quantity of eggs.
