ABSTRACT Tillandsia recurvata (Linnaeus) Linnaeus is an epiphyte that causes damage or death in trees. It is possible that the ruminant animals under extensive conditions can contribute to its control. The aim of the study was to determine the chemical and mineral value of Tillandsia recurvata (TR). An experiment was conducted at three different ecological environments during the four different seasons of the year in San Luis Potosi, Mexico. In each ecological environment, four samples of TR grown in mesquite trees (Prosopis spp.) were taken at four different season of the year to determine chemical content. Additionally, one more sample was taken to determine mineral content. Both the ecological environment and the season of the year affected (P<.001) the chemical and mineral content. However, according to the analyses, some mineral levels seem to be high and might compromise the health and consequently the animal production. In conclusion, TR has nutritional and mineral characteristics to be considered as a potential food source for ruminants at any time of the year. However, further research is needed to elucidate if TR can be included in the diet of ruminants in northern Mexico without compromising the health and the production.
