Abstract
La siguiente investigación presenta el uso de harina de zanahoria como aditivo alimenticio en la dieta de pollos camperos, como una alternativa para el mejoramiento de la pigmentación y producción, haciendo uso de productos naturales y no sintéticos. El estudio tuvo como objetivo evaluar los diferentes tratamientos empleados T1 (5%), T2(10%) y T3(15%) de harina de zanahoria (Daucus carota L.), e identificar el más óptimo en función del comportamiento productivo de los pollos, además de un análisis acerca de los carotenos en sangre e índice colorimétrico a través de colorímetro digital que verifica el empleo de este aditivo en su alimentación. La fase experimental se llevó a cabo en las instalaciones de la granja Experimental ECAA (Escuela de Ciencias Agrícolas y Ambientales) en la ciudad de Ibarra. Se hizo bajo un modelo experimental DCA con 4 tratamientos y 3 repeticiones en el cual se utilizaron 120 pollos camperos de 15 días de edad, los cuales fueron distribuidos de manera aleatoria en 12 diferentes grupos con 10 pollos/m2 en cada uno. Para establecer la efectividad del tratamiento más adecuado se empleó el ANOVA y test de Tukey al 5%, de esta manera se encontraron las diferencias entre cada tratamiento y la efectividad en la productividad. Una vez concluido el experimento se evidenció la efectividad del uso de harina de zanahoria en la alimentación de los pollos, beneficiando a los parámetros productivos, y de esta manera reduciendo el período de salida del pollo campero con un peso de 3653,66g (T1) 5% harina de zanahoria, la mejor conversión alimenticia está dada en la semana 8 del T1 (5 %harina de zanahoria) con 1,15. Dicha adición demuestra su rentabilidad, utilizando pigmentos naturales no dañinos para la salud y siendo más apetecido para el consumidor.
The following research presents the use of carrot flour as a food additive in the diet of free range chickens, as an alternative for improving pigmentation and production, using natural products and not pigments that are synthetic. The objective of the study was to evaluate the different treatments used for carrot flour (Daucus carota L.) and identify the most optimal one based on the productive behavior of the chickens, in addition to an analysis of blood carotenes and colorimetric index through digital colorimeter that verifies the use of this additive in your food. The experimental phase of this research was carried out at the facilities of the ECAA Experimental farm (School of Agricultural and Environmental Sciences) in the city of Ibarra. In this study, it was carried out under a DCA experimental model with 4 treatments and 3 repetitions in which 120 free-range chickens of 15 days of age were used, which were randomly distributed in 12 different groups with 10 chickens/m2 in each one. To establish the effectiveness of the most appropriate treatment, the ANOVA and Tukey's test at 5% were used, in this way the differences between each treatment and the effectiveness in productivity were found. Once the experiment is completed, the effectiveness of using carrot flour in feeding the chickens can be demonstrated, benefiting the parameters that were evaluated, reducing the period of release of the free-range chicken with a weight of 3653.66g (T1), This is due to an improvement in feed conversion, in which 1,15 was obtained as a better result for T1 with 5% carrot flour. This addition demonstrates its profitability, using natural pigments that are not harmful to health and being more desirable to the consumer.
