Excess dietary cholesterol may have an adverse effect on growth performance of early post-larval Litopenaeus vannamei

Table 2 Growth performance of shrimp fed a variety of experimental diets

Cholesterol levels, %	D10	D20.5	D31	D42	One way ANOVA (P value)
Growth performance
Initial number	1,000	1,000	1,000	1,000	/
IBW, mg	0.8	0.8	0.8	0.8	/
Final number	865.3 ± 33.5	806.3 ± 49.3	856.7 ± 24.7	853.7 ± 10.7	0.599 (ns)
FBW, mg	53.0 ± 1.5^a	41.3 ± 0.4^b	35.3 ± 4.1^b	33.5 ± 3.8^b	0.006
WG, %	6529 ± 192^a	5058 ± 44^b	4308 ± 514^b	4092 ± 480^b	0.006
SGR, %/day	15.5 ± 0.1^a	14.6 ± 0.0^ab	14.0 ± 0.4^b	13.8 ± 0.4^b	0.015
Survival, %	86.5 ± 3.4	80.6 ± 4.9	85.7 ± 2.5	85.4 ± 1.1	0.599 (ns)

Values are shown as mean ± SE of three replicates. Means within the same row and not sharing a common superscript are significantly different (Ducans, P < 0.05); ns, no significant difference detected (P > 0.05).
IBW (mg/shrimp): Initial body wet weight (mg/shrimp).
FBW (mg/shrimp): Final body wet weight (mg/shrimp).
WG (%): weight gain = 100 × (final body weight- initial body weight)/initial body weight.
SGR (%/day): specific growth rate = 100 × (ln final wt.- ln initial wt.)/total number of experimental days.
Survival (%) = 100 × (final shrimp number)/(initial shrimp number).
