Zusammenfassung:•Association between pre-housing fasting and diet physical form leads to:•Changes in body and gastrointestinal weights•Small intestine morphology commitment•Micropellet diet was beneficial for chicks fasted for 24 h before housing This study aimed to evaluate body and gastrointestinal development in broilers chicks subjected or not to pre-housing fasting and different diet physical forms during the first week of housing. Nine hundred chicks were distributed into a completely randomized design in a 3×3 factorial arrangement: 0, 24 and 48 hours(h) of fasting; mashed (MM), crushed (CC) and micropelletized (MP) physical forms. For each fasting period, 300 animals were housed in protection circles with 100 chicks each. On days 1, 3, 5 and 7 of feeding, six animals were randomly selected, previously weighed and euthanized to obtain organs biometrical and histological data. Chicks fasted for 24 h and 48 h were lighter compared to the 0 h group and the 24-h fasting x MP interaction had a positive impact on body weight at d7 (P
