Résumé
In the Caatinga is inserted a wide variety of native species, mostly deciduous and potential for forage use. However, the use of these species has been carried out without proper knowledge of the productive potential and almost no environmental control technique, there is need for more studies on the native plants of Caatinga. This study aimed to analyse arbustive-arboreal component of Four Caatinga species with forage potential for their incorporation in animal feed in the cities of Olho D’Água do Casado and Delmiro Gouveia, Alagoas. The experimental areas amount to a total of 1 ha of native Caatinga, which was subdivided into 100 plots of 10 mx 10 m, where it was analyzed the floristic and phytosociological arbustive-arboreal component of Caatinga and from this selected four species of arbustive-arboreal stratum with forage potential Pilosocereus gounellei F. A. C. Werder ex K. Schum Byles & G. D. Rowley, Pityrocarpa moniliformis (Benth.) Luckow & R. W. Jobson, Laetia apetala Jacq and Capparis flexuosa L. common in both environments, five times each. It was conducted a mapping distribution of the four selected species in the two areas and made bromatological chemical analysis, which evaluated the dry matter content (DM), mineral matter (MM), organic matter (OM), crude protein (CP), ethereal extract (EE), Neutral detergent fiber (NDF), acid detergent fiber (ADF) and Lignin (LIG). Questionnaires were administered together with farmers to identify the species used as forage for animals and how to use and management. The chemical components of the species P. gounellei, P. moniliformis, L. apetala and C. flexuosa indicates that the tree and shrub layer Caatinga can be a food source for ruminants of the semiarid region, especially in the dry season ; The association of the species P. gounellei that have water and food supply with other species native to the Caatinga that have higher levels of dry matter becomes a viable alternative to ruminant feed of the semiarid region, especially in water-scarce period ; The species C. flexuosa is indicated as good forage for animal feed, the dry matter, crude protein, mineral matter, neutral detergent fiber and lignin, and although it has a high ethereal layer content, has good palatability and available throughout the year can be associated with other plants in the diet of the animal ; The species P. moniliformis is an excellent forage because the nutritional values present in its composition, achieving meet the nutritional needs of animals, with great availability in the Caatinga, and the ease of handling ; The species L. apetala has high crude protein presenting itself as a good food and medicinal option for flocks of semi-arid region ; Cattle breeding of Settlements Nova Esperança (Olho D’Água Casado) and Maria Bonita (Delmiro Gouveia) consists of small herds distributed among cattle, sheep and goats raised extensively in the Caatinga ; The species of Caatinga producers more use in animal feed are Cereus jamacaru (Mandacaru) Pityrocarpa moniliformis (Angelim), Spondias tuberosa (Umbuzeiro) Pilosocereus gounellei (Xique-xique), identified as the toughest in the dry season ; Of the four species analyzed P. moniliformis presents aggregate spatial distribution in the two experimental areas.
