Effect of adding macro and micro minerals in pig feces fed diets with different levels of probiotic

Abstract

This study aimed to verify the effect of diets with different doses (0, 100, 200 and 300 ppm) of probiotic on daily fecal production (DFP) and level of macro and micro minerals infeces of nursing (1st and 2nd initial phases) and growing pigs and during total period. The DFP, as percentage of body weight, was different (P<0.05) among treatments only at 1 st initial phase. Fecal levels of macro and micro minerals were similar (P>0.05) among treatments, with exception of calcium and sodium excretion at 1st initial phase and calcium, zinc and nickel during total period. The addition of a poliprobiotic to diets do not affect fecal production of nursing and growing pigs. However, the presence of microorganisms, added (levels of 200 and 300 ppm) in diets for nursing and growing pigs reduced fecal excretion of calcium, zinc and nickel.
