Abstract

© 1999 American Registry of Professional Animal Scientists. Three experiments were conducted to determine the effect of a hydrated sodium calcium aluminosilicate (HSCA) on growth and carcass traits of finishing pigs. In Experiment 1, 32 barrows (initial weight = 26.7 kg) were fed one of two dietary treatments: 1) a corn-soybean meal basal (B) diet or 2) B. +. 0.50% HSCA. In Experiments 2 and 3, 64 barrows and gilts were used in a 2 × 2 factorial arrangement of treatments. Two percentages of HSCA (0 or 0.50%) were fed to barrows or gilts. In Experiment 1, average daily gain, feed intake, gain:feed, serum urea nitrogen (SUN) concentration, and carcass traits were not affected (P>0.10) by HSCA. Leaf fat weight was decreased (P<0.08) in pigs fed HSCA. In Experiments 2 and 3, no HSCA × gender interactions (P>0.10) were present; thus, barrow and gilt data were combined. In Experiment 2, average daily gain, feed intake, gain:feed, SUN, and carcass traits were not affected (P>0.10) by HSCA. In Experiment 3, average daily gain, feed intake, and gain:feed were not affected (P>0.10) by HSCA. Serum urea nitrogen was increased (P<0.05) in pigs fed HSCA. Carcass traits were not affected (P>0.10) by HSCA, with the exception of increased (P<0.10) total carcass fat (total body electrical conductivity) in pigs fed HSCA. Pork quality score for color was increased (P<0.09) in pigs fed HSCA, but scores for marbling and firmness-wetness were not affected (P>0.10). In summary, HSCA did not affect growth performance or consistently affect carcass traits.
