Crop-livestock integration is an efficient technique that enables cropping and animal production in the same area, takes advantage of all the benefits that this synergism provides, and results in greater sustainability and lower environmental impact. The objectives of this study were to evaluate the production, forage quality, and cattle performance with forages of the genus Brachiaria and Panicum maximum after intercropping with soybean in an integrated crop-livestock system and to assess the relationship between mulch biomass and soybean yield. The experimental design was completely randomised and consisted of a 4 × 5 factorial arrangement with four replicates. The treatments consisted of four forages, namely, Xaraes palisadegrass (Brachiaria brizantha cv. Xaraés), Congo grass (Brachiaria ruziziensis), Mombaça guinea grass (Panicum maximum cv. Mombaça), and Tamani guinea grass (Panicum maximum cv. BRS Tamani), intercropped with oversown soybean, and these treatments were evaluated over five grazing cycles. The results showed that Mombaça guinea grass and Xaraes palisadegrass were associated with higher forage production, but the highest forage quality was obtained with Tamani guinea grass. Mombaça guinea grass, Xaraes palisadegrass, and Tamani guinea grass resulted in the best pasture performance of animals under grazing in the off-season and thus generated more benefits in terms of the soybean yield. Congo grass was associated with reduced production, lower forage quality and decreased animal production during the grazing cycles. The pasture establishment through soybean over sowing proved to be an efficient technique that reduced the environmental impact of livestock, because of the greater use of soil nutrients and resulted in greater sustainability.

农牧一体化是一种有效的技术，可以在同一地区进行种植和动物生产，利用这种协同作用提供的所有好处，并提高可持续性并降低对环境的影响。本研究的目的是评估在农牧综合系统中与大豆间作后使用Brachiaria和Panicum属草料的产量、草料质量和牛性能，并评估覆盖物生物量与大豆产量之间的关系。实验设计是完全随机的，由 4 × 5 因子排列和四个重复组成。处理由四种草料组成，即 Xaraes Palisadegrass ( Brachiaria brizantha简历。Xaraés)、刚果草 ( Brachiaria ruziziensis )、Mombaça 几内亚草 ( Panicum maximum cv. Mombaça) 和 Tamani 几内亚草 ( Panicum maximum简历。BRS Tamani)，与超播大豆间作，这些处理在五个放牧周期内进行了评估。结果表明，Mombaça 几内亚草和 Xaraes Palisadegrass 与较高的牧草产量相关，但以 Tamani 几内亚草获得的牧草质​​量最高。蒙巴萨珍珠草、Xaraes 栅栏草和塔马尼珍珠草使动物在淡季放牧时的牧场表现最佳，因此在大豆产量方面产生了更多收益。刚果草与放牧周期期间产量下降、草料质量下降和动物产量下降有关。通过大豆过度播种建立牧场被证明是一种有效的技术，可以减少牲畜对环境的影响，
