Compensatory growth in the gibel carp following feed deprivation: temporal patterns in growth, nutrient deposition, feed intake and body composition.
Compensatory growth in the Chinese longsnout catfish, Leiocassislongirostris following feed deprivation: Temporal patterns in growth, nutrient deposition, feed intake and body composition.
The growth performance values of fish in 4-meals-a-day treatment with or without feed deprivation is the same as for fish which receive two meals a day with weekly deprivation (Table 2).
The 4-meals-a-day treatment with feed deprivation compared to four meals a day with no deprivation showed no difference in feed efficiency ratio value.
In addition, Miglavs and Jobling (1989) showed that the relative sizes of liver and viscera decreased with either feed deprivation for 16 weeks or restricted feeding, which was 10% of feed consumption at satiation feeding for 8 weeks in Arctic charr (Salvelinus aplinus) and increased to levels exceeding those of fish fed continuously to satiation after fish were transferred from restricted to satiation feeding for the following 8 weeks.
When rainbow trout (Oncorhynchus mykiss) and gibel carp (Carassius auratus gibelio) were starved for a defined period of time, body fat decreased, but body moisture and protein increased compared to fish without feed deprivation; however, the fish restored the body fat shortly after satiation feeding (Quinton and Blake, 1990; Xie et al., 2001).
However, a significant (Repeated measures ANCOVA; p < 0.0001) difference in body weight of fish was observed between C-8W and all other treatments with 2-week feed deprivation at week 2 (Figure 1).
The accelerated growth of olive flounder with a 2-week feed deprivation at week 6 and 8 resulted in no significant difference in final body weight of fish between the C-8W treatment and all other treatments in this study and indicated that full compensatory growth was achieved in all fish groups.
Significant improvement in weight gain and SGR of fish in 9WF-HP and 9WF-HPL, and 8WF-HP and 8WF-HPL treatments compared to those of fish in 9WF-HL, and 8WF-HL treatments with 1-, and 2-week feed deprivation
groups in this study probably indicated that dietary supplementation of protein or combined high protein and high lipid was more effective in improving compensatory growth of fish than dietary supplementation of lipid only regardless of 1- or 2-week feed deprivation
(2003) wherein the authors studied the effect of feed deprivation
for 24, 48 and 72 h post hatch and suggested the need to feed chicks immediately after hatch to ensure proper development of gastrointestinal tract, liver and pancreas (Noy and Sklan, 2001).
during molting led to decreased plasma T3 concentration and increased plasma T4 concentration.
