“…In the 1976 season the early closing resulted in c. 3x more green herbage than the late closing (942 and 278 kg DM/ha respectively), with similar proportions of green for both treatments. However, Clarke (1977) found that the greater amount of dead material on the early-closed block inhibited growth in early spring compared with the late-closed.…”

“…The absence of growth in autumn when dead herbage levels were high (High Mixed A, Fig. 4), low utilisation of dead material during grazing, and low digestibility of dead herbage, together with the deleterious effect of dead material on growth in the spring found by Clarke (1977), would suggest that accumulation of dead herbage in autumn has little benefit in a grass wintering system (or in any grazing system). Saving of reasonable levels of high quality leafy herbage at the start of winter should be the primary aim of a grass wintering system to ensure a supply of green herbage during winter, with the expectation that some of the green herbage would be lost as a protective mulch layer over the rest of the green herbage.…”

“…and cocksfoot have been shown to survive the winter better than Yorkshire fog (Holcus lanatus L.) and ryegrass (Lolium perenne L.) in the high country (Vartha & Clifford 1971). Clarke (1977) measured herbage quality on the same station as Allan et al (1976) with early (December) and late (mid April) closing. There were greater amounts of green herbage present in August from the early closing in two seasons, but more dead herbage present after early closing than late.…”

The quantity and quality changes of pasture in an all grass wintering system on a high country station, Central Otago, were studied at the end of the 1981 winter after an autumn of good pasture growth and during the 1982 autumn and winter after poor growth in the autumn. Higher levels of green herbage survived after the winter in 1981 compared with poor survival in 1982. Less than half of the green herbage present at the beginning of June was utilised during grazing, and losses of green herbage by frosting or senescence during June 1982 ranged from 35 to 70%. Green percentage of herbage was a good predictor of digestibility when values of 100% green and 100% dead material analyses were added to those of mixed herbage samples, with an average of 89% of variation in herbage digestibility being accounted for by the regressions of in vitro digestibility and % green. Prediction of digestibility from % green of mixed herbage samples alone was not as good (r 2 = 0.53 for June and 0.67 for July). Digestibility of 100% green herbage was high (82% mean) and varied little, whereas that of standing dead fluctuated, and was low (40% mean). Little, if any, dead herbage was eaten, and presence of dead herbage was of no advantage in autumn-saved pasture. There were no differences between clovers, grasses, or other species in winter survival or in digestibility of green herbage.
