title: Incorporation of sodium bicarbonate into laying rations. II. Effects on egg quality.
abstract: The replacement of 0.67% NaCl in the ration by 1% NaHCO3 leads to improvements of several parameters of the shell quality and some other egg quality characteristics in the Rhode Island Red breed. In the Fayoumi breed this influence was not clearly discernible. This also holds for an increase of the NaHCO3 content in the ration to 2%. Under the conditions in the AR Egypt the addition of 1-2% NaHCO3 for the Rhode Island Red is recommended in order to improve the shell quality and the internal quality of the eggs.
