Data included in regression analysis will be chicken weight and feed intake. •Diet: recommended for Cobb500 This project has received funding from the European Union‘s Seventh Framework Programme for research, technological development and demonstration under grant agreement No. 311794. 9 Sampling schedule Feacal samples In ovo Hatch -12 Feacal samples BW 0 1 4 BW 7 BW Feacal samples BW 14 21 BW 28 42 blood blood blood blood blood blood pancr pancr pancr pancr pancr transcript. pancr transcript.
