SILVA, C.A.M. et al. Quality of capim-de-raíz (Chloris orthonoton, doell) hay in small ruminants. Arch. zootec. [online]. 2013, vol.62, n.240, pp.595-598. ISSN 1885-4494.

The objective of this study was to characterize the chemical composition, intake and digestibility of dry matter (DM) and nutrients, ruminal degradation kinetics of DM and NDF and quantify the nitrogen balance in sheep fed Chloris orthonoton hay. The experiment was carried out with five sheep with 28.34 kg LW. The hay showed 90.66 % DM, 7.16 % CP and 65.34 % NDF. The digestibility of dry matter, crude protein and NDF were 52.8, 70.6 and 40.4 %, respectively. The animals showed low dry matter intake (1.4 % of BW), but positive nitrogen balance. Chloris orthonoton hay when done in flowering stage has a low nutritional value and is not recommended as single source of food for maintenance of sheep.

Keywords : Chemical composition; Digestibility; Intake.
