To evaluate dynamics in nutritional composition of tropical forages used in cattle production in Colombia a systematic research was made, using a regular search engine, for studies published in Colombia between 1985 and 2015, Those studies had to include chemical composition data, such as crude protein, neutral detergent fiber, acid detergent fiber and in vitro dry matter digestibility (CP, NDF, ADF, IVDMD). Likewise studies that reported productive parameters such as daily weight gain (DWG Kg/d), milk yield (MY Lt/d), Animals per hectare (UGG/ha), were included. A lineal regression model was used for chemical components and productive parameters for the period studied. Starting from the global research, 105 studies were included from 17 research database, from which 9 species were selected (species with more than 5 studies published). No lineal trends were observed in the time lapse analyzed, for neither chemicals fractions nor productive parameters related to forage quality. However for Brachiaria sp and Paspalum sp a positive trend was detected for UGG/ha (r2=0.54 y 0.53,respectively). Despite the low significance of the coefficients of determination of lineal regression model for the 9 species selected, an overall lineal increase in CP and IVDMD was observed, and also a lineal reduction for ADF (except for Lolium sp and Dichantium sp). Regarding to productive parameters, a slight positive trend was observed for the UGG/ha in most of the species analyzed. This kind of study becomes in a valuable tool in order to explain and to predict the nutritional behavior of the forage species and its effect on livestock productive parameters.
