Abstract: The n-alkanes have been used to estimate forage dry matter intake, digestibility and the diet composition in grazing animals. The objective this study was to compare chromium oxide and nalkanes techniques used to estimate forage intake. Twenty lactating dual-purpose cows receiving two sources of fat (treatments: conjugated linoleic acid (CLA) or Megalac (control)) plus 4 kg of concentrate were dosed with n-alkanes and chromium oxide to estimate the intake of stargrass (Cynodon nlemfüensis Vanderyst var. nlemfü… Show more

“…Oliveira et al (2007), em pesquisa com grama-estrela manejada com 26 dias de intervalo de desfolha, observaram 13,3% de PB. Apesar de a grama-estrela apresentar maiores teores de PB nas lâminas foliares, essa diferença não se repetiu nas amostras da fração bainha-colmo.…”

“…Regarding this result, the concentrate used in this study was composed mainly of seed and cereal derivatives and sub-products. Oliveira et al (2007) also found higher concentrations of C 23 and C 25 in concentrates based on ground corn, fish meal, soybean meal, wheat bran, and a vitamin-mineral mix rather than in the Cynodon nlemfuensis grass or in the leaf and stalk fractions of this species. The high mean dietary and fecal concentrations of the nalkanes C 23 and C 25 under the SC treatment do not concur with the results reported in the literature, where these markers are usually found in lower concentrations than other n-alkanes.…”
