The birds in a factorial arrangement (2 \u00d7 3) were placed into six treatment groups in a completely randomised design. The treatment groups differed in feed procedure, 6\u00a0h [early feeding (EF)] or 36\u00a0h [common feeding (CF)] post\u2010hatch, with or without IOF with beta\u2010hydroxy\u2010beta\u2010methyl butyrate (HMB) or calcium gluconate (CG) in a saline solution, and were examined for hatchability and performance parameters until 24\u00a0h post\u2010hatch. In addition, physical and histological characteristics of breast, jejunum and serum indices in 14 days post\u2010hatch and performance criteria until 35 days of age were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>On day 17 of the incubation period, eggs were subjected to the IOF procedure.
