| dc.description | The study was designed to determine if the incorporation of cannabis in balanced feed significantly influences the development of Lohmann Brown laying hens during their laying stage. We worked with 68 hens, distributed in a completely randomized block experimental design with three repetitions per treatment. The treatments include a group without control of cannabis use (T0) and three experimental groups with doses of 10 g (T1), 15 g (T2) and 20 g (T3) of cannabis per 10 kg of balanced food. The results indicated that the hens in the T0 group (without cannabis use) achieved the highest average weight (1946.78 g) at the end of the study. For its part, treatment T3 showed the greatest food waste (613.35 g), while treatment T1 presented the highest egg weights (964.8 g). These results reject the null hypothesis and support the alternative hypothesis, demonstrating that the Cannabis has a significant impact on the development of birds. However, it is noted that higher doses can negatively affect feed efficiency. Limitations of the study include the quality of the eggs and differences in the absorption of cannabis by the chickens. It is recommended that future research evaluate other concentrations, administration methods, and long-term effects on poultry production. | es_ES |

| dc.description.abstract | El estudio se diseñó para determinar si la incorporación de cannabis en el alimento balanceado influye significativamente en el desarrollo de gallinas ponedoras de la raza Lohmann Brown durante su etapa de postura. Se trabajó con 68 gallinas, distribuidas en un diseño experimental de bloques completamente al azar con tres repeticiones por tratamiento. Los tratamientos incluyen un grupo sin control del uso de cannabis (T0) y tres grupos experimentales con dosis de 10 g (T1), 15 g (T2) y 20 g (T3) de cannabis por cada 10 kg de alimento balanceado. Los resultados indicaron que las gallinas del grupo T0 (sin uso de cannabis) lograron el mayor peso promedio (1946.78 g) al finalizar el estudio. Por su parte, el tratamiento T3 mostró el mayor desperdicio de alimento (613.35 g), mientras que el tratamiento T1 presentó pesos de los huevos más elevados (964.8 g), Estos resultados rechazan la hipótesis nula y respaldan la hipótesis alternativa, demostrando que el cannabis tiene un impacto significativo en el desarrollo de las aves. No obstante, se destaca que las dosis más altas pueden afectar negativamente la eficiencia alimentaria. Entre las limitaciones del estudio se encuentran la calidad de los huevos y las diferencias en la absorción del cannabis por las gallinas. Se recomienda que investigaciones futuras evalúen otras concentraciones, métodos de administración y los efectos a largo plazo en la producción avícola. | es_ES |
