dc.description.abstractObjetivo: Probar tres niveles de 25-(OH)-colecalciferol en pollos de engorde de línea de alta incidencia de discondroplasia tibial, criados bajo condiciones de temperatura termoneutral y de temperatura alta, a una altitud de 2130 msnm. Metodología: Se utilizaron 384 pollos de 1 a 21 días de edad de la línea Ross 308, con peso inicial promedio de 43,97±1,25 g, distribuidos en un modelo factorial 2x3, dos temperaturas ambientales (termoneutral y temperatura alta) y tres niveles de 25-hidroxicolecalciferol (34,5; 69 y 93,5 µg/kg de alimento, como única fuente de vitamina D), cada uno con 8 repeticiones y 8 pollos por unidad experimental. Al día 21 de edad se determinaron el peso final, la conversión alimenticia y la mortalidad en cada una de las unidades experimentales. Además, se tomó una muestra de hueso de tibia, para realizar la medición cuantitativa del porcentaje de área con discondroplasia tibial. Resultados: Aunque los pollos alimentados con 93,5 µg/kg de vitamina D presentaron en los resultados biológicos menor porcentaje de discondroplasia tibial, la prueba estadística no muestra diferencia significativa (p>0,05) entre las medias de tratamientos. El peso final incrementó significativamente (p<0,05) en los pollos alimentados con 93,5 µg/kg de 25-hidroxicolecalciferol; y al desdoblar la suma de cuadrados dentro del factor temperatura, no se observaron diferencias estadísticas significativas (p>0,05). Conclusión: Con base en los resultados obtenidos en las condiciones del experimento, la adición de 25-(OH)-colecalciferol a una dosis de 93,5 µg/kg mejoró la respuesta productiva, sin embargo, no hubo diferencia en el grado de discondroplasia cuando las aves consumieron niveles de 25-hidroxicolecalciferol entre 34,5 y 93,5 µg/kg de alimento en pollos de engorde de 1 a 21 días.spa
dc.description.abstractObjective: Prove three levels of 25-hydroxycholecalciferol in broilers at a high risk of Tibial Dyschondroplasia incidence, raised under thermal neutral temperature conditions and high temperature, with an altitude of 2130 m above sea level. Methodology: 348 Ross birds from 1 to 21 days old were used, 308 with an average weight of 43.97±1.25 g, distributed in a factorial 2x3 model, two ambient temperatures (thermal neutral and high temperature) and three levels of 25-hydroxycholecalciferol (34.5, 69 o 93.5 µg/kg of food, as the only source of vitamin D), each of them with 8 repetitions and 8 birds per experimental unit. On the 21st day of age, the final weight, the feeding conversion and mortality in each experimental unit were determined. Moreover, a tibia bone sample was taken in order to conduct a quantitative measure of the percentage of area with Tibial Dyschondroplasia. Results: Even though birds fed with 93.5 µg/kg of vitamin D showed lower biological results of Tibial Dyschondroplasia, the statistical evidence does not reveal a significant difference between the treatment measures (p>0.05). The final weight increased considerably (p<0.05) in the birds fed with 93.5 µg/kg25-hydroxycholecalciferol; and when the results were analyzed in the temperature factor, significant statistical differences were not observed (p>0.05). Conclusion: Based on the obtained results under the experimental conditions, the addition of 25-hydroxycholecalciferol per dose by 93.5 µg/kg, improved the productive response. However, there was no difference in the degree of Dyschondroplasia when the birds consumed 25-hydroxycholecalciferol in 34.5 and 93.5 µg/kg of food in 1 to 21 days old broiler chickens.eng
