Safety of Improved Milbond-TX When Fed in Broiler Diets Limiting in Available Phosphorus or Containing Variable Levels of Metabolizable Energy
2007
Miles, R.D. | Henry, P.R.
Improved Milbond-TX (IMTX), a hydrated sodium calcium aluminosilicate, was added to broiler diets at 0, 1, or 2% in 2 experiments. In experiment 1, three concentrations of available P, 0.22, 0.32, and 0.42%, were combined with the IMTX in isocaloric and isonitrogenous corn-soybean meal-based diets and fed to male broilers for 21 d. In experiment 2, the IMTX was added to isonitrogenous broiler diets calculated to contain 2,940, 3,020, or 3,100 kcal of ME/kg and also fed for 21 d. Deficient dietary P reduced feed intake and BW at 7, 14, and 21 d of age, but IMTX had no effect even when fed at 8 times the amount recommended by the manufacturer (0.25%) to ameliorate the toxic effects of feed mycotoxins. Similarly, increasing the energy level of the diet resulted in improved BW and feed conversion, but IMTX fed at 8 times the amount recommended by the manufacturer had no detrimental effect on chick performance. There was no interaction found between IMTX and energy or available P for any performance measure. Addition of IMTX to the diet above the recommended concentration of the manufacturer also had no detrimental effect on percentage of toe ash or excreta moisture.
