Resumen
El presente estudio se desarrolló en la Unidad Experimental de Avicultura de la Universidad Nacional Agraria La Molina, con el objetivo de evaluar el efecto de diferentes niveles de inclusión de harina de papa (Solanum tuberosum) y carbohidrasas sobre el rendimiento productivo, la calidad del huevo y el mérito económico en gallinas ponedoras Lohmann Brown. Se emplearon 210 aves de cuarenta y seis semanas de edad, distribuidas en seis tratamientos (0 por ciento, 10 por ciento y 20 por ciento de harina de papa, con y sin 0,05 por ciento de β–glucanasa + xilanasa), bajo un diseño completamente al azar con arreglo factorial 3×2, durante doce semanas. Los resultados del análisis de varianza indicaron que no hubo diferencias significativas (P>0,05) en producción de huevos (72,44–74,67 por ciento), peso promedio de huevo (56,7–58,4 g), masa de huevo (40,25–43,61 g/ave/día), consumo de alimento (110,2–114,3 g/ave/día), conversión alimenticia (2,53–2,83), peso inicial, peso final y ganancia de peso. En relación con la calidad del huevo, se observó un efecto significativo de la inclusión de carbohidrasas sobre el espesor de la cáscara (p=0,02), evidenciando valores superiores respecto al control. Asimismo, el nivel de harina de papa influyó significativamente en la pigmentación de la yema (p<0,0001), con el mayor valor en el grupo control sin harina de papa (5,85 en la escala Roche), mientras que la inclusión de 10 y 20 por ciento redujo la pigmentación a 5,48 y 5,18, respectivamente. Por el contrario, no se encontraron diferencias significativas (P>0,05) en altura de clara, altura de yema ni en las Unidades Haugh. Finalmente, en la evaluación económica, el tratamiento control (0 por ciento de harina de papa y sin enzimas) registró la mayor retribución y mérito económico, debido a menores costos de alimentación y mayor rentabilidad en comparación con las dietas experimentales.
This study was conducted at the Experimental Poultry Unit of the Universidad Nacional Agraria La Molina, with the objective of evaluating the effect of different inclusion levels of potato meal (Solanum tuberosum) and carbohydrases on productive performance, egg quality, and economic merit in Lohmann Brown laying hens. A total of 210 hens aged forty-six weeks were distributed into six treatments (0 percent, 10 percent and 20 percent potato meal, with and without 0.05 percent β glucanase + xylanase), under a completely randomized design with a 3×2 factorial arrangement, of twelve week experimental period. Analysis of variance indicated no significant differences (P>0.05) in egg production (72.44–74.67 percent), average egg weight (56.7 tareas–58.4 g), egg mass (40.25–43.61 g/hen/day), feed intake (110.2–114.3 g/hen/day), feed conversion ratio (2.53–2.83), initial weight, final weight, or body weight gain. Regarding egg quality, the inclusion of carbohydrases significantly affected eggshell thickness (p=0.02), showing higher values compared to the control. Similarly, potato meal levels had a significant effect on yolk pigmentation (p<0.0001), with the highest value observed in the control group without potato meal (5.85 points on the Roche scale), while the inclusion of 10 percent and 20 percent reduced pigmentation to 5.48 and 5.18, respectively. In contrast, no significant differences (P>0.05) were found in albumen height, yolk height, or Haugh Units. Finally, in the economic evaluation, the control treatment (0 percent potato meal and no enzymes) recorded the highest return and economic merit, mainly due to lower feed costs and greater profitability compared with the experimental diets.
