In addition, Mg and Zn had a highly significant negative correlation ( p < 0.01) at 21 days old, while K and Se had a significant negative correlation ( p < 0.05) at 49 days old.
In addition, Mg and Zn had a highly significant negative correlation ( p < 0.01) at 21 days old, while K and Se had a significant negative correlation ( p < 0.05) at 49 days old.
We noted a positive correlation between Mg and K in the five growth stages of CV duck, which showed an extremely significant difference between 0 and 21 days old ( p < 0.01), as well as a significant difference between 35 and 63 days old ( p < 0.05).
In contrast, the deposition of Zn showed a significant ( p < 0.05) decrease with age, while the deposition of Se had a decreasing then an increasing trend, where its content was the highest at birth ( p < 0.05).
