The DM digestibility of German grass with protein content varying from 8.2 to 10.3 % and NDF from 66.4 to 61.8% ranged from 59 to 63%. Corresponding intake for sheep increased from 64.3 to 71.2 g/kg metabolic weight as digestibility decreased (Combellas et al., 1973).
German grass (Echinochloa polystachya) is more palatable to stock than para grass (Hannan-Jones et al., 2008)
Beef cattle and buffaloes
In Venezuala, in Criollo Limonero steers grazing Echinochloa polystachya pastures, supplementation with of 1 kg concentrate or Leucaena leucocephala did not modify dressing percentage, carcass traits, cut yield, cooking traits and Warner-Bratzler shear force (Rodas-Gonzalez et al., 2007; Rodas-Gonzalez et al., 2006). Animal supplementd with leucaena had a lesser proportion of white viscera compared to the control. All animals exhibited low levels of total lipids and cholesterol, which indicated that this meat could be sold as light meat or low fat meat which is interesting from a nutritional point of view for the consumer, especially as steaks had a good consumer acceptability and were considered as tender meats (Rodas-Gonzalez et al., 2007; Uzcategui-Bracho et al., 2008). Buffaloes have higher liveweight gains than cattle when fed on flooded pastures containing Echinochloa polystachya (Camarao et al., 2004; Sheikh et al., 2002). Buffaloes are better adapted to live in foodplain habitats and their rumen microflora has lower N requirements than microflora in cattle which excreted more N through urine (Moran, 1983). Gains differ around the year: they are higher in the dry period (up to 678 g/head/day in August) than at the end of the wet period (333 g/head/day in June) (Camarao et al., 2004).
In the Brazilian Amazon, buffaloes are not used intensively for commercial milk production even if some farmers have obtained high yields (Camarao et al., 2004). The nutritive value of a mixture of Echinochloa polystachia and Brachiaria arrecta can be improved by the allowance of multi-nutritional blocks ad libitum to female buffaloes (Lopez-Maduro et al., 2001).
