PERFIL FERMENTATIVO DA SILAGEM DE SORGO, CAPIM-TAMANI E ESTILOSANTE EM SISTEMA INTEGRADO

Abstract

Crop-livestock integration systems are efficient technologies for diversifying production and promoting agricultural sustainability. However, the interactions between the annual crop and tropical forages make the integrated system dynamic and complex, mainly as a result of competition between crops, making it necessary to know more about the integrated production of three crops simultaneously for silage production. In this sense, the objective was to evaluate the fermentative profile of sorghum silage combined with tamani grass and Bela stylosants in integrated systems. The experimental design used was randomized blocks, with four replications. The treatments consisted of silage of: sorghum in monoculture; tamani grass in monoculture (Panicum maximum cv. BRS Tamani); Bela stylosantes in monoculture (Stylosanthes guianensis cv. BRS Bela); sorghum intercropped with tamani grass; sorghum intercropped with Bela stylosants; Estiloantes Bela intercropped with tamani grass and sorghum intercropped with tamani grass + stylosantes Bela, totaling 28 experimental silos. The results showed that sorghum silage intercropped with tamani grass and Bela stylosants reduces pH, buffer capacity and total dry matter losses and effluent production and increases DM and lactic acid in relation to tropical forage silages. Therefore, triple intercropping can be recommended for silage production, as it balances tropical forage silages.
