Evaluation of Dietary Salt Levels for Swine. I. Effect on Gain, Water Consumption and Efficiency of Feed Conversion1,2,

Abstract

Four experiments utilizing 73 crossbred barrows were designed to study the effect of dietary salt (NaCl) levels on average daily gain (ADG), feed conversion and water consumption. Conventional corn-soybean meal diets with varying amounts of supplemental salt and deionized water were offered ad libitum. The salt levels studied ranged from .06 to .48% total dietary salt equivalent.

Feed conversion and average daily gains were inferior (P<05) below .20% total dietary salt equivalent. Water consumption was lower for the pigs with deficient salt intakes. Positive correlations between salt intake and average daily gain were significant and up to 48% of the variability of average daily gain can be accounted for by dietary salt alone.

With a corn-soybean meal diet containing .06% salt equivalent or less prior to supplementation and the drinking water free of salt, the animals of these experiments required from .10 to .14% supplemental salt to sustain optimal growth and feed conversion.
