Table 9. Carapace calcium and phosphorus levels in Pacific white shrimp (Penaeus vannamei) fed the experimental diets for 8 weeks

Diets	Calcium1)	Phosphorus2)
VD0	3.92 ± 0.14	1.34 ± 0.03
VD45	4.15 ± 0.11	1.26 ± 0.05
VD90	4.42 ± 0.53	1.18 ± 0.03
VD135	3.61 ± 0.47	1.43 ± 0.10
VD270	4.10 ± 0.26	1.35 ± 0.09

Quadratic	0.468	0.095

Values are mean of quadruplicate (n = 4) and presented as mean ± SD. Different superscripts in each column indicate significant differences (p < 0.05). The determined dietary vitamin D₃ levels were 12, 35, 101, 132, and 294 μg/kg for VD0, VD45, VD90, VD135, and VD270, respectively.
