title: [Use of sugar cane harvest residues in cattle fattening in the Republic of Cuba. 1. The physical and chemical composition of the residues and the effect of NaOH treatment on their in vitro and in vivo digestibility].
abstract: The harvesting remains of sugar cane (crowns, leaves, sheaths, parts of stalks), which are rich in crude fibre, were investigated. The content of crude nutrients, their digestibility and the energy concentration of the harvesting remains largely correspond to the values of cereal straw. After the treatment with growing amounts of NaOH (0, 4, 6, 8, 10 g/ 100 g DM) a significantly increasing digestibility of the dry matter (31.9, 47.0, 56.1, 61.9, 67.6%) was ascertained in in-vitro experiments. In digestibility experiments with wethers an increased digestibility of the dry matter from 36.6 to 57.6% and of the energy from 39.3 to 56.2% after the treatment with 4 g NaOH/100 g DM could be ascertained in comparison with untreated harvesting remains. Energy concentration increased from 324 to 445 EFU cattle/kg DM and thus approached that of the hay of Bermuda grass (Cynodon dactylon), one of the most important fodder grasses of Cuba. After the feeding of harvesting remains treated with NaOH significant changes in the water and mineral metabolism could be ascertained.
