Twenty-four mature, dry, female goats were grazed no Brachiaria-dominated pasture to study the effects of tethering on intake. Animals were either tethered for 4h (T4) or 8 h) (T8), or grazed freely for 8h (FG) during a 28 day period. Intake was estimated by two methods: (1) short-term BW changes and (2) n-alkanes as internal markers. The BW technique was suitable for conditions in developing countries, although correction factors for changes in bite rate through the grazing day may be needed in order to estimate total intake. The alkane technique may be more appropriate to estimate total intake, but it involves sophisticated and expensive chemical analyses. Animals grazed for 4 h had similar total daily intakes to those grazed for 8 h: 1055 day-1, 1183 g day-1 and 1259 g day- for T4, T8 and FG treatments, respectively. |
