“…Observed digestibility of browse undertaken by Toure et al (1998) appeared lower than in this study, and this might indicate the extent to which goats used in this study might have adapted to the consumption of browse as compared with sheep used in that study. The OM digestibility values of A. senegalensis and A. hypogaea appeared to be higher than those of Medicago sativa hay, which is considered to be of good nutritive value (Ramirez-Orduna et al 2003), but similar to that of an intensively managed grassland silage in a digestibility study conducted by Bruinenberg et al (2003). Digestibility values of extensively managed grassland silages were however lower than the digestibilities observed in this study (Bruinenberg et al 2003) with the exception of P. erinaceus and A. africana whose values were comparable.…”

An in vivo digestibility trial was conducted to evaluate the digestibility of six forages. These were selected indigenous browse species and groundnut haulms in Lawra and Jirapa Districts of the Upper West Region of Ghana. Groundnut haulms served as a control due to its known good digestibility in small ruminants. Thirty West African Dwarf (WAD) young castrated billy goats with a mean age of 8 months were used. The average live body weight was 8.9 ± 0.1 kg. The animals were randomly assigned to the six treatments and replicated five times in a completely randomized design. They were confined in metabolism cages. The adaptation period was 3 weeks after which data was taken for 10 days. The treatments were the leaves and tiny twigs of T1 Annona senegalensis, T2 Ficus gnaphalocarpa, T3 Pericopsis laxiflora, T4 Pterocarpus erinaceus, T5 Afzelia africana, and T6 (control) Arachis hypogaea. Feed intake, faecal matter and urine output were measured. The results indicated that dry matter (DM) contents of the feedstuffs were less than 50% but crude protein (CP) contents were higher than the minimum required for sustaining ruminants. Neutral and acid detergent fibre contents were high, and F. gnaphalocarpa, in particular, contained a higher level of phosphorus (P). The amounts of feed intakes were typical of most fodder species with the exception of P. laxiflora and P. erinaceus, which were lower (P < 0.05). The apparent digestibility values were also typical of most fodder species but the digestibility of A. africana fibre appeared to be lower. Nitrogen retention was positive for all test species with the exception of P. laxiflora, which was negative. Mortality was recorded in animals on P. laxiflora, and the rate was high. Pericopsis laxiflora leaves, even though morphologically similar to the leaves of P. erinaceus, were not a suitable fodder. Ficus gnaphalocarpa appeared to be the overall best fodder species in terms of nutrient uptake.

“…These include several shrubs, small trees, spontaneous forbs, fruits, flowers, pods and cacti which are essential components of natural communities such as shrublands and woodlands (Juarez-Reyes et al 2008). They cover large areas and constitute grazing lands for all domestic and wildlife small ruminants (Ramı´rez-Ordun˜a et al 2003). However, forage production and nutritive value vary widely among species, varieties, plant parts, phenological state and seasons of the year.…”

Native forages such as trees Quercus eduardii and Quercus grisea; shrubs such as Atriplex canescens, Acacia constricta, Acacia shaffneri, Cassia wislizeni, Celtis pallida, Condalia lycioides, Cordia parvifolia, Flourencia cernua, Larrea tridentata, Mimosa biuncifera and Prosopis leavigata; forbs such as Coldenia greggii, Dalea bicolor, Jatropha dioica and Parthenium incanum; cacti such as Opuntia imbricata, Opuntia leptocaulis and Opuntia leucotricha; red and white fruits from O. leucotricha; fruits from O. leptocaulis, O. imbricata and A. canescens; pods from P. leavigata; pods from A. shaffneri and flowers from Yucca spp. were collected to estimate and compare the mineral content. Plant samples were collected during the dry and wet seasons of two consecutive years (2006Á2007) at seven locations situated in four counties of the state of Durango, Mexico. All macrominerals and trace elements were significantly different among plants within each group of plants. The Ca, Mg, K, Fe and Mn content of most plants were in sufficient amounts to satisfy adult range requirements; however, P, Na, Cu and Zn resulted with marginal deficiencies.

“…CP content of inflorescences of Y. carnerosana was lower than that of alfalfa, but it was high enough not to be limiting to grazing animal production. This level of CP compares favorably with leaves of most desert fodder shrubs of northern Mexico (Ramirez and Hernandez, 1997;Ramírez-Orduña et al, 2003).…”
