“…For the first seven weeks on the foggage the oesophageally fistulated wethers were able to select a diet with a CP concentration theoretically sufficient to maintain live mass of a 70 kg ewe (NRC, 1985) (Figure 1). Barnes & Dempsey (1993) found that at the start of grazing in late May, sheep grazing kikuyu foggage could evidently select a diet of relatively high quality. During mid-August when animals were removed from the paddocks, the quality of the selected herbage was at or below that required for maintenance of body weight.…”

“…Cross (1979) observed CP concentrations that varied from 118 to 145 g/kg DM for foggage samples collected from late-May to mid-June. Barnes & Dempsey (1993) noted mean IVDOM and CP concentrations of 513 and 82 g/kg DM respectively in oesophageal kikuyu foggage samples collected by sheep during the period May to August. The high fibre concentration of the kikuyu foggage is not unexpected, considering that the herbage was four to six months old, frosted and weathered during the winter (Table 1).…”

“…It was suggested by Barnes & Dempsey (1993) that foggage produced with short rest periods will be of higher quality than that produced with longer rest periods. However, the difference in nutritive value is likely to be small, and the amount of forage could be negatively affected by shorter rest periods.…”

“…Therefore, kikuyu foggage could play an important role in a fodder flow programme to maintain dry ewes during the winter in a system where their lambs were weaned onto green pastures. However, conflicting results on the performance of sheep grazing kikuyu foggage have been reported by Rethman & Gouws (1973) and Barnes & Dempsey (1993). The objective of this study was to determine the potential of kikuyu foggage to maintain dry South African Mutton Merino (SAMM) ewes in winter when the grazing of the kikuyu was stopped in different months of summer, and when utilized using two different grazing systems.…”

“…Apart from its suitability as summer grazing, it can be used as foggage (standing hay) during the winter period of May to mid-August (Barnes & Dempsey, 1993). Cross (1979) found that the crude protein (CP) concentration of kikuyu foggage varied between 118 and 147 g/kg dry matter (DM) during the period, late-May to mid-June.…”

Kikuyu (Pennisetum clandestinum) is a summer growing tropical pasture species well adapted to the Midlands of KwaZulu-Natal. Kikuyu foggage (standing hay) could play an important role in a fodder flow programme to sustain dry ewes during late winter after their lambs have been weaned in mid-winter. The potential of kikuyu foggage to supply in the feed requirements of dry ewes was evaluated over four winter periods. The foggage was obtained by closing off the kikuyu to grazing during either late January or late February. The foggage was grazed for eight weeks, from mid-July to mid-September, using either strip or continuous grazing systems. Closing off date did not significantly influence the chemical composition of the material on offer. The ewes in the different treatments lost between 4.7 and 10.3% of their initial body weight over the grazing period. In vitro digestible organic matter (IVDOM) of the foggage declined as winter progressed and was positively correlated with the body weight loss of the ewes. Foggage utilization varied between 36.7 and 43.5%, indicating a high proportion of fodder wastage. The body weight loss of the dry ewes during the grazing period suggested that kikuyu foggage in the KwaZulu-Natal Midlands was unable to sustain the body weight of the dry ewe.
