Salt in the formulation of poultry diets
Salt is an ingredient commonly used in poultry diets as a source of sodium (Na) and chlorine (Cl), important minerals for the organism. It is very rich in these minerals, as it has more than 95% purity, and specifically contains 38% sodium and 58% chlorine (Blas et al. 2019). Its addition in the diet is importance because the main ingredients, like cereals or soybean meal, are low in sodium; besides, chlorine in salt is highly bioavailable in poultry (Schaible 1941).
