Abstract

Nine Alpine castrated males goats averaging 34.7 kg, were kept in digestibility cages and allocated into two blocks. The animals remained 28 days in hay (700g/day) and concentrate (200g/day) diets without or with 5.2 or 10.4 g/day of dicalcium phosphate (FBIC). Feces outputs were measured on the seven last days to determine the apparent digestibility coefficient (DC) of nutrients. The increase in FBIC ingestion led to a linear increase (P<0.05) in the plasmatic P and in OMDC and DMDC, and did not change the salivary P neither CPDC, CFDC, NDFDC and TDN. The increase in the DC of some nutrients due to the increase in FBIC intake lead to the conclusion that levels of Ca and P in the not supplemented diet was insufficient for microbial activity in the rumen.
