The breeding systems of the small ruminants are extensive in the great majority, in which the animals are created in areas of native pasture named Caatinga, being necessary the knowledge on the chemical composition and its characteristics of feed degradation is crucial to increase nutrient use efficiency. Thereat, the objective of this study was to evaluate the chemical composition, the minerals, the carbohydrates and nitrogenous compounds fractionation, the degradability, in vitro dry matter nd the in vitro gas production of arboreal species, those are consumed by goats and sheeps. The species evaluated were Cnidoscolus phyllacanthus (Muell. Arg.) Pax. et K. Hoffman, Mimosa tenuiflora (Willd.) Poiret, Myracrodruon urundeuva Fr. All., Poincianella bracteosa (Tul.) L. P. Queiroz, Spondias tuberosa Arr. Cam. and Ziziphus joazeiro Mart. It was found that Mimosa tenuiflora has a higher crude protein quantity (174.9 g.kg-1 DM). Spondias tuberosa and Myracrodruon urundeuva had the highest values for total carbohydrates compared to the other species analyzed. As for the fractionation of nitrogenous compounds, the highest proportion of fraction A was found for Cnidoscolus phyllacanthus (375.5 g.kg-1 CP). Among the species studied, Cnidoscolus phyllacanthus is highlighted with the highest ruminal degradation (61.63%) and dry matter digestibility (627.1 g.kg-1 DM), reflecting higher gas production (206.02 mL.g-1 DM). Cnidoscolus phyllacanthus, Poincianella bracteosa and Myracrodruon urundeuva showed a greater availability of nutrients in the rumen which is fundamental to increase the amount of ruminal microbial protein which reaches the small intestine for use by the animal.

The aim of this study is to identify patterns in the production and storage of grains in Brazil from 1980 to 2015 and analyze the conditions of similarity of each group. The technique of data mining Clustering was applied through the algorithm k-means to transform the historical series of grain storage and production into a group of similarities. The results show that the application of the mining technique coherently delimited the regions, which had a direct relation with the expansion of the agricultural frontier in Brazil, proving to be efficient for this application. Four clusters were formed. The first is composed by States of the South Region referring to consolidated crops since the 1960s. The second is composed of States of the Midwest and Southeast regions, revealing the second phase of the country's agricultural expansion. The third is made by states that do not have agricultural potential by soil and climate conditions, with an inexpressive agriculture. Finally, the fourth cluster shows the new Brazilian agricultural frontier called MATOPIBA (Maranhão, Tocantins, Piauí and Bahia), which has reached records in the production and export of grains driven by the installation of new transport routes. |
