In the two experiments involving 452 bobwhite quail chicks, seven diets containing the following salt supplements, were compared: No additional salt; 0.25 per cent KaCl; 0.50 per cent NaC1; 0.75per cent NaCl; 1.00 per cent NaCl; 0.25 per cent Na2SO4; and 0.50 per cent KCl. All four diets containing sodium chloride gave about equal results in bird-growth, and produced better weights than the diet containing no additional salt. Survival was high on the 0.50, 0.75 and 1.00 per cent levels, especially the 0.75 per cent level. Feed consumption increased directly as the salt level of the diet was raised.....The results on the Na2SO4 and KCl while better than those on no saline supplementation, and somewhat inferior to those on NaCl, nevertheless are inconclusive because of inconsistency.
