 | Abstract 67The effect of forage quantity offered upon the nutritive value of three tropical grasses.Caceres,-O; Santana,-H Estacion Experimental de Pastos y Forrajes 'Indio Hatuey', Matanzas, Cuba. Pastos-y-Forrajes. 1989, 12: 3, 273-277; 9 ref. In feeding experiments in metabolic cages, sheep were offered Pennisetum purpureum X P. typhoides [P. americanum], Panicum maximum cv. Likoni or Cynodon dactylon at levels 10, 30 or 50% higher than normal daily intake. Digestible CP intake was 18.7, 23.5 and 30.6 g/animal day with P. purpureum X P. typhoides, 13.2, 46.8 and 65.6 g/animal day with P. maximum and 12.6, 49.6 and 102.6 g/animal day with C. dactylon for 10, 30 and 50% levels, resp. ME intake was 4.6, 5.9 and 6.7 MJ/animal day with P. purpureum X P. typhoides, 3.3, 6.7 and 8.3 MJ/animal day with P. maximum and 4.8, 8.4 and 12.3 MJ/animal day with C. dactylon for 10, 30 and 50% levels, resp. Differences in digestible CP intake and ME intake were significant for P. maximum and C. dactylon. OM digestibility also increased as supply level increased. This abstract relates to the following species:
