“…In spring, grass consumption accounted for 61.1% of total intake (Table 2), higher than that of woody species (37.0%) and acorns (1.9%). These proportions have also been reported by Tieszen et al (1979), Malechek and Provenza (1983), Morand-Fehr et al (1983), Pfister and Malechek (1986b). More specifically, Bourbouze (1980) reported April grass consumption to be 72% of intake, while the present study gives an approximate figure of 80% for the same month.…”

The contribution of three strata of pasture (grass, woody species and acorns) to the diet of goats during a grazing season was studied. Results showed that in autumn-winter acorns (61.6%) were the dominant dietary dry-matter component, followed by woody species (25.8%) and grass (12.6%). The opposite was true in spring when the greatest contribution was from grass (61.1%), followed by woody species (37%) and acorns providing a mere 1.9%. In summer, however, woody species increased their contribution to 47.4%, thus constituting an important intake component for grazing goats in the region. Acorns proved to be an important resource, as they are produced at a time when there is a shortage of grass and when woody species have limited nutritional value. Results showed that goats should not be classed solely as browsers but placed midway between strictly herbivorous animals and true browsers, given the contribution of grass to their diet, although an opportunist capacity for adaptation to changes in the quality of available feeds should also be taken into account.

“…In animal diets, the fruits and flowers were required seasonally (Pfister and Malechek, 1986). Sheep feed generally consist of more than 50% grasses during all the seasons, while shrub components tends to increase during dry seasons in Africa (Migongo-Bake and Hansen, 1987).…”

In the present investigation, 161 plant species were judged for palatability purpose in Tehsil Takht-eNasrati, District Karak, Khyber Pakhtun Khawa, Pakistan. The study shows that 161 plant species including 22 (13.4%) trees, 23 (14%) shrubs and 116 (72.6%) herbs were grazed among five animals in different seasons. Of the 161 recorded species, 29 species (18.01%) were non palatable, 32 species (19.88%) were highly palatable, 43 species (26.71%) were mostly palatable, 34 species (21.12%) were less palatable and 23 species (14.29%) were rarely palatable. The overall animals preferred 83 plant species (62.88%) in a fresh form, single species (0.76%) in dry form and 48 species (36.4%) in both forms. The goat preferred the most plant (118 species, 33.52%), camel (79 species, 22.4%), cow (61 species, 17.33%), sheep (51 species, 14.5%) and donkey (43 species, 12.22%). The most preferred species by animals were Zizyphus mauritiana, Acacia modesta, Cyperus species, Dichanthium annulatum, Euphorbia prostrata and Kickxia ramosissima. In winter, there is less availability of palatable species in plain areas from an agriculture point of view, while it is reverse in hilly areas. It was observed that palatability and animal preference increased in summer. As such, a recommendation was made to evaluate the nutritional and mineral status of high palatable plants.

“…In northeast Brazil, increasing herbaceous production during the wet season, a time when forage quantity and nutritional quality are not generally limiting, may not enhance livestock production during the dry season, a time when forage quantity and nutritional quality are often limiting [27,28]. In addition, leaf litter from deciduous trees is an important forage reserve during the dry season.…”

Clearcutting is a common practice for removing woody vegetation in the semiarid tropics of northeast Brazil. The prevalent belief is that clearing increases carrying capacity for livestock by increasing herbaceous vegetation, yet iittle empirical evidence exists to support or refute the contention. We investigated the implications to small ruminant nutrition of clearcutting in the semiarid tropics of northeast Brazil. We found that biomass of herbaceous species increased sixfold following cutting of trees, but much of this increase was in the form of poorly palatable stem. The large supply of leaf litter from woody species that was typical of uncleared areas during the dry season was replaced by persistent green foliage on coppicing trees the year following clearing. This green foliage may enhance the nutritional quality of the diets of sheep and goats foraging on cleared areas during the dry season.
