| dc.description | The research was designed to evaluate whether the administration of cannabis in the drinking water and feed significantly impacts the development of Lohmann Brown laying pullets during their rearing period. The study included 120 pullets distributed in a completely randomized block design with three replicates per treatment. The treatments consisted of different concentrations of cannabis residues in both water and feed, with a control group without cannabis (T0) and three experimental groups with doses of 15 g (T1), 30 g (T2), and 45 g (T3) of cannabis in 10 liters of water and 10 kg of feed. The results showed that the pullets of treatment T3 (45 g of cannabis) reached the highest weight (1380 g) at the end of the study. However, treatment 2 had the highest feed intake (5236, 19 g) and T1 had the highest water intake (1.08 L), suggesting that T2 doses of cannabis increased feed intake and T1 increased water consumption. The T3 treatment had the highest feed conversion (2.3), indicating a reduction in feed efficiency. These findings refute the null hypothesis and support the alternative hypothesis, suggesting that cannabis significantly impacts chick development. However, feed efficiency at higher doses should be carefully considered. Limitations of the study include sample size and variability in the uptake of cannabis by birds. For future research, it is recommended to explore different concentrations and m ethods of administration, as well as their long-term impact on poultry production | es_ES |

| dc.description.abstract | La investigación se diseñó para evaluar si la administración de cannabis en el agua de bebida y en la alimentación impacta significativamente el desarrollo de pollitas de postura Lohmann Brown durante su período de levante. El estudio incluyó 120 pollitas distribuidas en un diseño en bloques completamente al azar con tres repeticiones por tratamiento. Los tratamientos consistieron en distintas concentraciones de residuos de cannabis tanto en el agua como en el alimento, con un grupo control sin cannabis (T0) y tres grupos experimentales con dosis de 15 g (T1), 30 g (T2), y 45 g (T3) de cannabis en 10 litros de agua y 10 kg de alimento. Los resultados mostraron que las pollitas del tratamiento T3 (45 g de cannabis) alcanzaron el mayor peso (1380 g) al final del estudio. Aunque, el tratamiento 2 registró el mayor consumo de alimento (5236, 19 g) y el T1 registro el mayor con sumo de agua (1,08 L), sugiriendo que dosis de T2 de cannabis incrementan la ingesta y el T1 el consumo de agua. El tratamiento T3 presentó la conversión alimenticia más alta (2,3), indicando una reducción en la eficiencia alimenticia. Estos hallazgos refutan la hipótesis nula y apoyan la hipótesis alternativa, sugiriendo que el cannabis impacta significativamente el desarrollo de las pollitas. Sin embargo, la eficiencia alimenticia en dosis más altas debe considerarse cuidadosamente. Las limitaciones del estudio incluyen el tamaño de la muestra y la variabilidad en la absorción de cannabis por las aves. Para futuras investigaciones, se recomienda explorar diferentes concentraciones y métodos de administración, así como su impacto a largo plazo en la producción avícola | es_ES |
