Ontogeny of the gastrointestinal motility in young broilers.
Gastrointestinal motility of young broilers (1, 8 and 15 days old) was measured by means of 14C-polyethylene glycol-4000. Two motor patterns can be observed: GI segments anterior to ileum increased their motility proportionally to the broiler age. GI segments below ileum decreased their motility when the broiler age is increased. It is concluded that these motor patterns are due to immaturity of gastric motility, early learning of food intake regulation and/or interference between prenatal and postnatal nutrition. Proventriculus and duodenal loop showed to be transit segments, with independence of the broiler age.
