The Caatinga biome has a wide variety of plants which, despite their irregular distribution, are frequently used to feed animals. This study aimed to evaluate the gas production kinetics of Caatinga plants: Malva (Herissantia crispa), Aroeira (Myracrodruon urundeuva), Marmeleiro (Croton sonderianus), and Bamburral (Hyptis suaveolens). Buffel grass (Cenchrus ciliaris), a cultivated forage, was used as a control. For this evaluation, samples of Aroeira, Malva, Marmeleiro, Bamburral, and Buffel grass were weighed and then incubated in 100 ml flasks containing rumen fluid and buffer solution at 39 °C in a water bath. The volume of gases produced was measured with graduated syringes at various times. The parameters of in vitro degradation kinetics were estimated from cumulative gas production using the NLMIXED procedure of SAS (Statistical Analysis System, Cary, USA). Buffel grass showed higher gas production than the other samples (77.64 ml), followed by the Caatinga samples, Malva and Aroeira (58.16 ml and 54.05 ml, respectively), which were statistically similar. In conclusion, we suggest that Malva and Aroeira are forage plants with promising potential to improve the nutrition of ruminants in arid regions, given their high protein content, moderate fiber content, and characteristics related to gas production identified with the in vitro digestibility test.
卡廷加生物群落有各种各样的植物，尽管它们分布不均，但常被用于喂养动物。本研究旨在评估卡廷加植物的产气动力学：锦葵（Herissantia crispa）、阿鲁埃拉（Myracrodruon urundeuva）、番石榴（Croton sonderianus）和薄荷（Hyptis suaveolens）。栽培牧草水牛草（Cenchrus ciliaris）用作对照。为了进行此评估，称取阿鲁埃拉、锦葵、番石榴、薄荷和水牛草的样本，然后在39℃的水浴中于装有瘤胃液和缓冲溶液的100毫升烧瓶中孵育。在不同时间用刻度注射器测量产生的气体体积。使用SAS（美国北卡罗来纳州卡里市统计分析系统）的NLMIXED程序根据累积产气量估算体外降解动力学参数。水牛草的产气量高于其他样本（77.64毫升），其次是卡廷加样本锦葵和阿鲁埃拉（分别为58.16毫升和54.05毫升），它们在统计学上相似。总之，鉴于锦葵和阿鲁埃拉蛋白质含量高、纤维含量适中以及体外消化率测试确定的与产气相关的特性，我们建议它们是有潜力改善干旱地区反刍动物营养的饲料植物。
