The goal of this research was to study the effect of Pb concentration in forages to its digestibility (in vitro). It was done through two stages : (1) Pb analysis in forages using Atomic Absorbans Spectrophotometer method (2) Forages Digestibility analysis exposed to Pb using in vitro method. This research was held for one month from Mei to June 2009 in Animal Nutrition and feed laboratory of S…
