Table 2 from the paper ‘Problems associated with broiler breeder entry into lay: a review and hypothesis’ by Y. Eitan and M. Soller, WPSJ Vol. 65(4): 641-648 is missing a column.
Below is the correct table.
Table 2 Illustrative examples comparing quantitative effects of optimal feed restriction (OR) vs. ad libitum (AL) feeding, to the effects of optimal restriction (OR) vs. moderate over-feeding (OF). Diff. are OR minus AL, or OR minus OF, as applicable. Cit., citation; U, units, see footnote for details.
1Meijerhof (2005) reports greater mortality in broiler females under over-feeding, but does not give actual values. Our own commercial experience (Y.E.) is that over-feeding can result in excess mortality in the range of +0.2% to +0.4% per week, for the first months of production.
