The objective of this study was to characterize a species of Furcraea foetida (L.) Haw as form of ruminant feeding in the city of Vertente do Lério-PE, as well as characterizing its chemical-bromatological aspects, carbohydrate fractionation, in vitro digestibility of dry matter, and in vitro gas production. The characterization of the form of use was carried out through a questionnaire applied as an interview in 92 properties of 10 villages in the city of Vertente do Lério-PE. Chemical-bromatological analyzes and in vitro tests were performed at the Animal Nutrition Laboratory (LANA) of the Federal Rural University of Pernambuco, Garanhuns Academic Unit (UFRPE / UAG). The experiment was conducted in a completely randomized design; it was a genre of Furcraea and three phenological stages (young, intermediary and mature). Dry matter was analyzed; mineral matter; organic matter; neutral detergent fiber; fiber in acid detergent; crude protein; lignin acid detergent; ethereal extract; in vitro dry matter digestibility, and cellulose, hemicellulose values and carbohydrate fractionation. Furcraea foetida has been used for more than 50 years in the town of Vertente do Lério-PE and there have never been reports of intoxication, abortions or other occurrences due to its use in ruminant feeding, offered to all age groups of animals, where its use comes from popular knowledge of the inhabitants of the region. In the chemical bromatological characterization, a difference (P< 0,05) was observed between the stages for the contents of ethereal extract and cellulose, obtaining a higher cocncentration of these compounds for the mature stage. The non-fibrous carbohydrate concentrations were higher than the fibrous carbohydrate concentration at al phenological stages, obtaining a mean of (566.5/kg MS). The high concentrations of non-fibrous carbohydrate influenced the kinetics of gas productions in vitro, demonstrating a bigger availability of nutrientsin the rumen. For in vitro dry matter digestibility parameters, no difference (P< 0,05) was observed between the phonophases, in which the values found were high. Above 89% wich can be explained due to the higher non-fibrous carbohydrates concentration and lower amount of lig of lignin found. In view of the results obtained, Furcraea foetida is characterized as a plant that conserves its nutrients in the different phenological stages evaluated, a positive factor for the production of ruminants.
