“…A similar pattern of seasonal variation in CP content was also reported by other researchers (Karachi, 1998;Peiretti and Gai, 2006). DM, NDF and ADF contents increased as plants matured (Papachristou and Papanastasis, 1994;Karachi, 1998;Peiretti and Gai, 2006). These results are both in agreement with the report of Kamalak et al (2005), who found that NDF and ADF contents increased and CP content decreased with increased maturity.…”

“…Its use for forage is becoming a common practice in China and other parts of the world with a temperate climate due to the high leaf biomass and high nutritive value for livestock when compared with other woody fodder species (Baertsche et al, 1986;Papachristou and Papanastasis, 1994;Papanastasis et al, 1997;Ainalis and Tsiouvaras, 1998;Burner et al, 2005). Moreover, no significant differences have been observed between goats fed R. pseudoacacia and at 300-600 g kg -1 in terms of average daily gain.…”

Samples of leaves, stems and whole plant of tetraploid Robinia pseudoacacia harvested at four different growth stages (first rapid growth, slow growth, second rapid growth, and leaf-colour changing) were analysed for chemical composition and in situ disappearance of protein and fibre using the nylon bag technique. The crude protein content was the highest in leaves, followed by whole plant, and the lowest in stems, while the opposite trend was found for dry matter, NDF, and ADF. Moreover, the crude protein content of the three plant parts decreased during maturation. Effective degradability of crude protein was higher for stems (519.0 g kg -1 ) than for whole plant (353.6 g kg -1 ) and leaves (270.4 g kg -1 ). Effective degradability of ADF was significantly higher in leaves than in the whole plant and stems. Ruminal disappearance of nutrients in the three plant parts was higher during the first rapid growth stage than at later stages.

“…The silvopastoral systems are another agro-forestry combination where woody fodder species can be key sources of nutrients for livestock (e.g. Papachristou and Papanastasis, 1994;Rigueiro-Rodríguez et al, 2005). Goat grazing can benefit the production of trees (oil palms, rubber trees, coffee, etc.…”

a b s t r a c tGoats have developed in harmony with local conditions of climate, terrain, vegetation, and even pathogens over centuries in many areas, while they have been blamed of causing environment degradation in other ones. The paper summarizes the situation of goat's population worldwide, the status of the breeds and the multiple implications of their conservation, the interactions of goats with other animal species (wild or domestic) and the main issues regarding the consequences of goat grazing from the environmental point of view. It underlines that most of the environmentally harmful effects of goat grazing arise from improper management practices at very high grazing pressures whereas goat grazing can be a useful tool for conservation if managed adequately. Moderate grazing pressures can be compatible with high levels of biodiversity and provide externalities, whereas high intensity at short term can be a valuable tool for weed control. Goat genetic heritage is seriously threatened and requires more studies and greater support from national and international institutions, in parallel with other efforts in rural development, especially for remote areas which hold an outstanding reservoir of livestock diversity adapted to the local conditions and managed by impoverished communities. A multidisciplinary approach of scientists, policy makers, rangeland managers and local communities is required for the design of future sustainable management plans.

“…Due to the high levels of difficult-to-digest lignin and secondary metabolites, most woody species are generally avoided by cattle (Gordon 2003). However, browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures (Papachristou and Papanastasis 1994;Lehmkuhler et al 2003;Bakker et al 2004;Allcock and Hik 2004). The consumption of woody plants increases when high quality forage is unavailable, often under dry weather conditions (Holechek et al 1982;OwenSmith and Cooper 1987;Fritz et al 1996) or in late summer (Leloup et al 1996).…”

Short-Term Effects of Cattle Browsing on Tree Sapling Growth in Mountain Wooded Pastures

et al. 2006

Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountainwooded pasture. Two size classes (ca. 12-17 cm and 41-59 cm) of each of 4 species (Picea abies, Abies alba, Acer pseudoplatanus and Fagus sylvatica) were exposed to zero, low and high grazing intensities. We measured the proportion of saplings browsed and the effect of browsing on growth. A mowing treatment within the zero grazing intensity treatment showed no significant effect on sapling growth. One percent of the large saplings but 25% of the small saplings escaped browsing. Saplings were better protected when surrounded by taller vegetation. The proportion of saplings browsed was not significantly different among species although evergreen tree saplings lost a larger proportion of biomass than deciduous species when browsed. Under grazing, average current-year shoot production and total aboveground biomass of all species were significantly reduced. Browsing effects tended to be smaller at the lower grazing intensity. Because the deciduous species were least reduced in aboveground growth, especially under the low grazing intensity, we conclude that at least in short-term, deciduous species are less affected by cattle browsing.
