Evaluation of the replacement of corn with sweet potato in the feeding of laying hens in an organic production system
The article aims to evaluate the productive response of birds when fed with sweet potato meal as a substitute for corn meal. The experiment took place in the field in two rural properties with organic certification in the region of Londrina-PR. Forty-eight red mixed breed laying birds were used. They were evaluated for production parameters, external and internal egg quality standards during 4 cycles of 21 days. For the productive parameters such as laying rate, feed conversion and egg mass, there was a statistical difference (p<0.05) with a superior result for corn bran. For external egg quality variables, no statistical differences were found (p<0.05) between treatments. For the parameter husk weight, a statistical difference was found with a superior result for the treatment with corn bran. For the analysis of internal egg quality, a significant difference was found for corn bran for the variables height, weight and yolk diameter. For albumen height, yolk color, Haugh unit, yolk percentage, albumen percentage, yolk index, yolk and albumen pH, no statistical significance was found. As they did not differ from the corn treatment, the parameters were satisfactory for egg production with sweet potato bran.

El artículo tiene como objetivo evaluar la respuesta productiva de las aves cuando se alimentan con harina de camote en lugar de harina de maíz. El experimento se realizó en campo en dos propiedades rurales con certificación orgánica en la región de Londrina-PR. Se utilizaron 48 aves ponedoras de raza mixta roja. Se evaluaron los parámetros de producción, estándares de calidad externa e interna de los huevos durante 4 ciclos de 21 días. Para parámetros de producción como tasa de postura, conversión alimenticia y masa de huevo, hubo diferencia estadística (p<0.05) con un resultado superior para salvado de maíz. Para las variables de calidad externa del huevo no se encontraron diferencias estadísticas (p<0.05) entre tratamientos. Para el parámetro peso de cascarilla se encontró diferencia estadística con un resultado superior para el tratamiento con salvado de maíz. Para el análisis de calidad interna de huevos se encontró diferencia significativa para el salvado de maíz para las variables altura, peso y diámetro de yema. Para altura de albumen, color de yema, unidad Haugh, porcentaje de yema, porcentaje de albumen, índice de yema, pH de yema y albumen, no se encontró significación estadística. Al no diferir del tratamiento con maíz, los parámetros fueron satisfactorios para la producción de huevos con harina de camote. porcentaje de albúmina, índice de yema, pH de la yema y albúmina, no se encontró significancia estadística. Al no diferir del tratamiento con maíz, los parámetros fueron satisfactorios para la producción de huevos con harina de camote. porcentaje de albúmina, índice de yema, pH de la yema y albúmina, no se encontró significancia estadística. Al no diferir del tratamiento con maíz, los parámetros fueron satisfactorios para la producción de huevos con harina de camote. O artigo tem o objetivo de avaliar a resposta produtiva de aves quando alimentadas com farelo de batata-doce em substituição ao farelo de milho. O experimento ocorreu a campo em duas propriedades rurais com certificação orgânica na região de Londrina-PR. Foram utilizados 48 aves de postura da raça rubro mista. Foram avaliadas quanto a parâmetros produtivos, padrões de qualidade externa e interna de ovos durante 4 ciclos de 21 dias. Para os parâmetros produtivos como a taxa de postura, conversão alimentar e massa de ovos, houve diferença estatística (p<0,05) com resultado superior para o farelo de milho. Para as variáveis de qualidade externa de ovos, não foram encontradas diferenças estatísticas (p<0,05) entre os tratamentos. Para o parâmetro peso de casca encontrou-se diferença estatística com resultado superior para o tratamento com farelo de milho. Para a análise de qualidade interna de ovos encontrou-se diferença significativa para o farelo de milho para as variáveis altura, peso e diâmetro de gema. Para altura de albúmen, coloração de gema, unidade Haugh, porcentagem de gema, porcentagem de albúmen, índice de gema, pH de gema e albúmen, não foram encontradas significâncias estatísticas. Ao não diferir do tratamento com milho, os parâmetros foram satisfatórios para produção de ovos com o farelo de batata-doce.
