Abstract: (5541 Views)
This experiment was carried out to study the effect of sodium chloride from
drinking water and feed intake on the quality of egs from laying hens. Four hundred
and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age
were used. Seven experimental treatments containing different levels of salt supplied
by feed and/or drinking water were compared. Increasing salt intake by the addition of
NaCI to drinking water or feed intake reduced shell thickness, shell ash and increased,
the number of damaged eggs. Shell calcium was not affected hy added salt, however,
the addition of salt to the food reduced shell-breaking strength. Breed differences
influenced the traits studied, except for shell percentage and shell calcium. Sodium
chloride intake from drinking water was more effective in reducing shell quality than
salt from food.
