Influence of PhyzymeÒ on Commercial Leghorns Fed Corn-soy Diets Full Article

Abstract The objective of this experiment was to determine the influence of Phyzyme ® on performance and profits of commercial Leghorns fed con-soy diets. Seven diets were fed to Hy-line W-36 hens (n = 840, 8 replicates of 15 hens per treatment) during Phase 1 (from wk 21 to 33). The treatments consisted of a control diet containing 0.38 nonphytate phosphorus (NPP) and a 2 × 3 factorial arrangement with two dietary NPP levels (0.11 and 0.26%) and three phytase sources (no phytase, Natuphos ®, Phyzyme ®). Results showed that dietary NPP levels had significant effects on egg production, egg mss, egg weight, egg specific gravity, and NPP intake. The addition of Phyzyme ® significantly increased egg production and egg mass of hens fed the deficient-phosphorus diet (0.11% NPP) to levels that were similar to hens fed the control diet (0.38% NPP). Although f eed intake of hens fed the diets supplemented with Phyzyme ® or Natuphos ® was significantly less than that of hens fed the control diet, there were no significant differences in egg mass and egg production between the control diet and the diets supplemented with Phyzyme ® or Natuphos ® . Feed conversion and egg specific gravity of hens fed the diets supplemented with Phyzyme ® were significantly better than those of hens fed the control diet. Phyzyme supplementation had no effect on egg weight, egg specific gravity, body weight, and mortality. There were no significant differences in egg production, feed intake, egg weight, egg mass, feed conversion, egg specific gravity, mortality, and body weight between the diets supplemented with Natuphos ® and the diets supplemented with Phyzyme ® . In conclusion, the addition of Phyzyme ® had positive influences on performance and profits of commercial Leghorns fed corn-soy diets.

Key words: Hens, phytase, Phyzyme ®
