Resumo: | ABSTRACT The present study evaluated the effects of early post-hatch feeding on the growth and development of the gastrointestinal tract (GIT) of mule ducks reared in the humid tropics to five days of age. A total of 120 newly hatched mule ducklings were selected and randomly assigned to four treatment groups. Each with 30 birds, (T1, T2, T3, and T4) is based on four feeding regimes (feed accessed at 3, 24, 36, and 48 hours post-hatch) for five days. The ducklings were euthanized each day and the parameters: small intestinal samples were processed for histological analysis and histometrical parameters including villi length and width, crypt width and depth, and the number of goblet cells per villus was measured, statistically analyzed using ANOVA and tabulated. The results of this study indicated that the earliest post-hatch feeding (at 3 hours post-hatch) showed the highest body weight (99.65 g), heavier (GIT) organ (p&lt;0.05), highest duodenal length (120.71 cm), than other feeding times. The villi height of the three segments of the GIT increased (p&gt;0.05) continuously regardless of the post-hatch feeding times. Based on the results, it was concluded that feeding at 3 hours post-hatch promoted the growth and development of the GIT faster than 24, 36, and 38 hours post hatch feeding.
