Crude protein of piatã grass leaf blade in systems in integration

This study aimed to evaluate the crude protein contents of Piatã grass (Urochloa brizantha Piatã) leaf blade in a crop-livestock-forest integration system. The experiment was carried out in the area of Embrapa Beef Cattle, in Campo Grande – MS, Brazil, in the 2018/2019 agricultural year. The experimental design was in randomized blocks with the treatments arranged in subdivided plots, with 3 treatments in the plots (ICLF28; ICLF22; ICL) and 4 repetitions. The harvest months were January, February, March, April and May 2019, the following distances from the eucalyptus rows: ICLF28 (7m, 10m, 11m, 9m, 4m); ICLF22 (3m, 7m, 10m, 7m, 3m). The sampling locations were identified by letters A, B, C, D, E (North-South direction). The Piatã Grass was harvested at ground level, the material obtained was separated into leaf blade, stem with sheath and senescent material. The samples were taken for drying and after drying they were ground and subjected to crude protein analysis. The higher crude protein contents in the leaf blades were verified in the months of February, in the three system.
