The objective of this study was to quantify the forage yield, determine its nutritive value, and evaluate the movement pattern, weight variation and body condition score of goats managed on sites of the Brazilian Caatinga grassland (Dry Tropical Forest) in different seasons, at the Lisboa settlement located at the south bank of Piauí river, in the towns of São João do Piauí and Pedro Laurentino at Capivara mountain, Piauí, Brazil, in two study sites, one constituted by shrubby Caatinga (site I) and the other by arboreal Caatinga (site II). The highest forage mass value (1,534.57 kg DM ha⁻¹) was recorded on the arboreal site. The mass of forage plants found on the sites differed among plants and months. The species Senna macranthera had the highest yield in March (177.35 kg DM ha⁻¹) on the shrub site, while Arrabidaea ateramnantha had the highest yield in February (710.65 kg DM ha⁻¹) on the arboreal site. The litter mass differed among sites, with the greatest amount found on the shrub site (1,785.96 kg DM ha⁻¹). Crude protein, acid detergent fiber, acid detergent insoluble nitrogen and in vitro dry matter digestibility contents were greater on the arboreal site. Dry matter and protein differed among months, showing an inversely proportional relationship. Litter nutritional variables did not differ (p < 0.05). In the Caatinga, goats travel an average of 6.24 km day⁻¹, with maximum movement of 7.36 km day⁻¹ in the dry season. The highest weight of the goats (33.06 kg BW) and the lowest body score (2.53) occurred in the transition season from the rainy to the dry season, and the lowest weight occurred in the dry season (26.93 kg BW). The botanical composition of the grassland determines the forage mass between months of the year. In this semi-arid region, goats follow a movement pattern defined by the herbage allowance and water availability.

本研究的目的是量化草料产量，确定其营养价值，并评估巴西卡廷加草原（干燥热带森林）不同季节、不同季节、不同季节饲养的山羊的运动模式、体重变化和身体状况评分。里斯本定居点位于皮奥伊河南岸，位于巴西皮奥伊卡皮瓦拉山的圣若昂杜皮奥伊镇和佩德罗·劳伦蒂诺镇，有两个研究地点，一个由灌木状卡廷加组成（地点一），另一个由树栖卡廷加组成（站点二）。最高的草料质量值（1,534.57 kg DM ha ^-1）记录在树栖地。现场发现的饲料植物的质量因植物和月份而异。灌木地Senna macranthera 3 月份产量最高（177.35 kg DM ha ^{-1 ），而乔木地}Arrabidaea ateramnantha 2 月份产量最高（710.65 kg DM ha ^-1）。不同地点的凋落物质量有所不同，其中灌木地点的凋落物质量最大（1,785.96 kg DM ha ^-1）。树栖地粗蛋白、酸性洗涤纤维、酸性洗涤不溶性氮和体外干物质消化率含量较高。干物质和蛋白质随月份不同，呈反比关系。窝窝营养变量没有差异（p  < 0.05）。在卡廷加，山羊平均每天移动 6.24 公里^-1，在旱季最大移动量为 7.36 公里每天^{-1 。}山羊体重最高（33.06 kg BW）和最低体重（2.53）出现在雨季向旱季的过渡季节，最低体重出现在旱季（26.93 kg BW）。草原的植物组成决定了一年中几个月之间的草料质量。在这个半干旱地区，山羊遵循由牧草供应量和可用水量决定的运动模式。
