2. We collected data on voluntary food intake in mammals on forage-only diets and 22 related this to dietary neutral detergent fibre (NDF) content, assuming a nonlinear 23 correlation between these measurements. Generally, the paucity of corresponding data 24 is striking. 25 3. Elephants and pandas showed very high food intakes that appeared unrelated to 26 dietary fibre content. Only in small rodents, and possibly in rabbits, was an increase in 27 food intake on forages of higher NDF content evident. In particular, other large 28 2 herbivores, including horses, followed patterns of decreasing intake with increasing 29 forage NDF, also observed in domestic cattle or sheep. 30 4. For large herbivores, empirical data therefore do not -so far -support the notion that 31 intake is increased in response to declining diet quality. However, data are in accord 32 with the assumption that most large herbivores have an anticipatory strategy of 33 acquiring body reserves when high-quality forage is available, and reducing food 34 intake (and potentially metabolic losses) when only low-quality forage is available. 35 5. Intake studies in which the influence of digestive strategy on food intake capacity is 36 tested should be designed as long-term studies that outlast an anticipatory strategy and 37 force animals to ingest as much as possible. 38 6. We suggest that a colonic separation mechanism coupled with coprophagy, in order to 39 minimize metabolic faecal losses, is necessary below a body size threshold where an 40 anticipatory strategy (living off body reserves, migration) is not feasible. Future 41 studies aimed at investigating fine-scale differences, for example between equids and 42 bovids, should focus on non-domesticated species. 43

“…The similarly low (P<0.05) mean DM1 of goats fed diets 1 and 2 (49.88gkg-'BWO may be attributed to their relatively high CF content (Table 1). A considerable body of authors are in support of kw DM1 due to high CF content of forage (Jones et al, 1972;El Hag, 1976;Sharma et al, 1977;Huston, 1978;Devendra, 1g78;Brown et al, 1984Brown et al, , 1988Hennessy et al, 1983;Huston et al, 1988;Lascano et al, 1993). Feed efficiency of goats led diet 3 with 40% water hyacinth inclusion (g gain/kg feed) (47.24±5.80) was superior (P<0.05) to the corresponding (P>0.05) mean (40.55±5.80) of goats fed diets 1 and 2 with 30% water hyacinth inclusion.…”

“…The heifers of Spragg et al (1986) had intakes of alkali-treated straw (on a per kg W 075 basis) which were approximately midway between those of the cattle and buffaloes studied here. Direct comparisons of VFI between cattle and buffaloes have been inconclusive, some authors reporting higher intakes by cattle (Grant et al 1974;Bhatia et al 1979Bhatia et al , 1980Ponappa et al 1971), others reporting no significant between-species difference (Johnson et al 1968;Moran et al 1979;Moran et al 1983) and yet others observing significantly higher intakes by buffaloes (Williams & Dudzinski 1982;Sharma & Mugdal 1975;Sharma & Rajora 1977). Clearly, further investigation is required before drawing conclusions about the usefulness of prediction equations derived from data on Bos taurus animals in temperate areas to prediction of intakes by working cattle (often Bos indicus or Bos taurus x Bos indicus crosses) and buffaloes under tropical conditions, especially when only poor-quality roughages are the major feedstuff.…”

Intake, digestion and gastro-intestinal mean retention time in Asiatic buffaloes and Ayrshire cattle given two contrasting diets and housed at 20° and 33 °C

S U M M A R YFour adult (4-5-7 years old) swamp buffaloes (Bubalus bubalis) and four adult (4-5 years old) Ayrshire cattle (Bos taurus) were housed in climate chambers maintained at 20° or 33 °C and given ad libitum access to a medium-quality, complete pelleted diet (AA6) or a lower-quality pelleted diet of alkali-treated barley straw supplemented with urea, sulphur, minerals and vitamins (ATS). Using a balanced double cross-over design, each animal was studied at each temperature and whilst consuming each of the two diets in experimental periods lasting 20 days. On day 13 of each period, animals were given single doses of two nonabsorbable markers, and food intake and complete collections of faeces were measured for the remainder of the period. Blood samples were taken at the end of each period.Voluntary food intakes on a per kg body weight (W) or per kg W 0 ' 5 basis were significantly higher for the cattle than for the buffaloes, although this difference was reduced with the lower-quality diet and at the higher temperature. Cattle appeared to be more heat stressed at 33 °C than the buffaloes, but species had little effect on digestion or gastro-intestinal mean retention time. Calculations suggested that a greater proportion of digestion of ATS than of AA6 occurred postruminally.tropics. For example, data are needed on the energy costs of work (Lawrence 1985), on specific nutrient The requirements for energy and nutrients of rumi-needs for muscle metabolism in ruminants (Leng nants used as draught animals are poorly understood.1985) and on the voluntary intake of working animals Whilst recognizing the paucity of data specific to such (Weston 1985). Draught animals in the tropics animals, attempts have been made (Mathers 1984; frequently subsist on poor-quality roughages which Mathers et al. 1985;Lawrence 1985) to calculate the would be expected to reduce the intake of dry matter energy needs of draught oxen using as a framework (DM) and hence put a low ceiling on potential ME the Agricultural Research Council (1980) proposals intake (Agricultural Research Council 1980). Theorbased upon Blaxter's (1962) metabolizable energy etical calculations have indicated that, with poor-(ME) system and designed for nonworking sheep and quality diets, low voluntary food intake (VFI) may be cattle in temperate regions. Graham (1985) reviewed, a major constraint on work output (Mathers et al. briefly, the relevance of the Agricultural Research 1985).
