Table 2. Effects of various durations of post-hatch food (deprivation or food and) water deprivation (PHFWD) (0, 24, 48, 72 hours) on relative yolk sac weight at 3 days of age for chickens deprived of both food and water (FW) and chickens deprived of only food (FO).
Average values of relative yolk sac weight are expressed as relative values compared to 0 hours (no food and water deprivation), which is set at 100. N = 19 records.
| Relative value after post-hatch food and water deprivation for a period of1 | ||||
|---|---|---|---|---|
| Treatment | 0 hours (0–12 hours) |
24 hours (≥12–36 hours) |
48 hours (≥36–60 hours) |
72 hours (≥60–84 hours) |
| Food and water deprivation (FW) | 100a | 118.0a | 121.8a | 84.6a |
| Food deprivation only (FO) | 100a | *2 | *2 | 219b |
1 Values lacking a common superscript differ significantly (P<0.05).
2 A * in a cell indicates that insufficient records were available to do the analysis.
