Effects of the extract from cinnamon, garlic, ginger, lemongrass and guava leaf on the growth in Grimaud ducks
This experiment was conducted to evaluate the effects of cinnamon, garlic, ginger, lemongrass, and guava leaf extracts (DC) on the growth of Grimaud ducks at different levels of addition to ducks’ drinking water: NT1 (0% DC), NT2 (0.5% DC), NT3 (0.6% DC), and NT4 (0.7% DC) on duck weight, feed consumption, weight gain, feed conversion ratio, and survival rate for 120 Grimaud ducks aged 1 to 49 days. The experiment was designed using a completely randomized design with 3 replications. The results showed that at 7 weeks of age, the highest weight of experimental ducks was observed in treatment group NT4 (0.7% DC) (3300 g/duck), followed by NT2 (0.5% DC) 3030 g/duck, NT3 (0.6% DC) 3136 g/duck, and the lowest in NT1 (control) 2866 g/duck, with statistically significant differences (p<0.05). Feed consumption in ducks from week 2 to week 7 differed significantly (p<0.05), with NT4 (0.7% DC) consuming less feed than the other three treatments. Weight gain in experimental ducks from week 2 to week 7 differed significantly (p<0.05), with NT4 (0.7% DC) achieving the best weight gain, significantly better than the other three treatments. The best feed conversion ratio was observed in NT4 (0.7% DC). Thus, adding 0.7% extracts of cinnamon, garlic, ginger, lemongrass, and guava leaves to the ducks' drinking water helped Grimaud ducks grow well
