DESCRIPTION OF PROBLEMA principal goal of nutritionists is to provide birds with a balanced diet that maximizes production at the least cost. Meat bird performance is maximized when feeding pelleted diets (Patton et al., 1937; Hussar and Robblee, 1962; Jensen et al., 1962). However, the nutritional value of feed presented to birds in feed pans throughout the house may not align with diet formulati ...

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 ...
