John Boney (Pennsylvania State University)    New generations of feed enzymes are included to enhance nutrient utilization. This study was designed to evaluate the efficacy of a new generation phytase, HiPhorius (HP), and protease, ProAct 360, when fed to peaking hens. Dietary treatments included Positive Control (PC), Negative Control 1 (NC1) at 0.15% nPP, NC1+600 FYT/kg HP, NC1+90 ...

Description of problemFeed ingredients and feed manufacturing account for 60 to 70% of production costs in an integrated poultry operation. Modern commercial broilers are fed predominately pelleted diets, and researchers have demonstrated how improving pellet quality (PQ), by increasing the percentage of pellets in the diet, further enhances bird performance (Proudfoot and Sefton, 1978; Dozier et ...

Nutritionists have access to various ingredients that fulfill methionine (Met) requirements of broilers. Amino acids (AA), such as DL-methionine, are nearly 100% bioavailable while methionine hydroxy analogs are shown to be relatively less bioavailable.Thus, this experiment aimed to determine the efficacy of using a 65% DL-methionine and 35% limestone dilution product (65DLM) compared to a methion ...
