A 10-d trial was conducted to investigate the relationship of Ca particle size (CPS), dietary Ca level (DCL), limestone source (LS), limestone solubility in vitro (LST) and in vivo (LSV), and limestone retention in the gizzard (LRG). A total of 120 molted Leghorn hens, 88 wk of age, were randomly assigned into a 2 x 3 x 4 factorial arrangement of treatments with LS (A and B), DCL (1.95, 3.72, and 5.32%), and CPS of each limestone source (average U.S. Screen Nos. 5, 8, 14, and 27). The in vitro… CONTINUE READING
