Resumo


Abstract. The objective of this experiment was to evaluate the performance of laying quails fed diets containing 21 and 24% crude protein, three electrolytic balances (200, 275 and 350 mEq/kg diet) and two forms of electrolytic balance increase (potassium and sodium + potassium). A total of 720 animals were distributed in two tests on random blocks design in 3 × 2 factorial arrangement, with six replicates and ten birds/experimental unit. Birds started the experiment at 120 days of age and were kept in the treatment for a period of 84 days, subdivided into four 21-day periods. For the level of 21% crude protein, the addition of potassium carbonate (K2CO3) promoted increase in egg mass. For the level of 24%, the results showed that the combined addition of potassium carbonate and sodium carbonate (K2CO3 + Na2CO3) presented better laying rate, egg mass, feed intake and feed conversion. Regardless of the protein level utilized, the best results were achieved with 200 mEq/kg diet.
