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 |
