“…Therefore, all browse species evaluated in this study would be good protein supplements provided that they were adequately degraded and non-toxic to the rumen microbes and host animal. The preference of differences in the CP concentration across the plants is inconsistent with the reports of Mekoya et al, 2008;Mekonnen et al, 2009;Ngodigha andAnyanwu, 2009 andArigbede et al, 2011. In the present study, the CP concentration of the browse species was greater than the minimum level of 7-8% CP in DM required for optimum rumen function and feed intake in ruminant livestock (Norton, 1994;Van Soest, 1994;McDonald et al, 2002).…”

“…This obviously adds to the poor performance of ruminant livestock. Improvement of the performance of ruminants in Sub-Saharan Africa (Kaitho et al, 1998;Mekonnen et al, 2006Mekonnen et al, , 2009Mekoya et al, 2008) calls for using the methods of extending the availability and quality of local feedstuffs. One potential way for increasing the quality and availability of livestock feeds is the use of various multipurpose trees and shrubs (MPTS) (Ngodigha and Anyanwu, 2009).…”

ABSTRACT:The study was aimed at determining the chemical composition, in sacco ruminal dry matter and organic matter degradability of leaves and fruits of tropical condensed tannin rich multipurpose tree species (MPTS). The MPTS studied were Ekebergia capenesis, Ficus sycomorus, Maesa lanceolata, and Rhus glutinosa. Chemical composition of dry matter (DM), crude protein (CP), crude ash (CA), ether extract (EE), crude fibre (CF), neutral detergent fibre (NDF), non-fibre carbohydrates (NFC), and condensed tannin (CT) was determined. In sacco rumen degradability was measured using three rumen fistulated Holstein FriesianBoran cross steers at 0, 6, 12, 24, 48, 72, and 96 h. The DM and organic matter (OM) degradability data were fitted to the equation Y = a + b(1 -e -ct ). The values for each chemical constituent ranged 5.43-11.49% (CA), 7.97-17.06% (CP), 1.57-31% (EE), 12.20-27.5% (CF), 5.84-39.30% (NFC), and 7.2-16.72% (CT). Ekebergia capensis leaves had the greatest values for slowly degradable fraction (b), effective degradability (ED), and rate of degradation (c) in DM (P < 0.001) whereas E. capensis fruit had significantly the greatest soluble fraction (a), potential degradability (b), and effective degradability (ED) values as compared to the a, PD, and ED values in the fruits of other plants(P < 0.001). Yet in OM degradation kinetics, the greatest and least values of potential degradability (PD) were recorded for F. sycomorus (89.89%) and E. capensis (55.90%) leaves (P < 0.001). Similar to the rapidly soluble fraction a, ED was found to be the greatest in fruits as compared to leaves of the plants (P < 0.001). Generally variation of plant parts led to significant differences in chemical composition, DM, and OM degradability and the degradable parameters. The leaves and fruits recorded more than 60% DM and OM degradability at 24 h, which implied that they were all greatly degradable in the rumen.

“…The CP content of all the seven fodder tree species was well above the minimum (70-80 g kg −1 DM) level required for ideal ruminal fermentation [24], but it was below the content reported for five planted forage legumes, Moringa spp. and foliage of four highland fodder tree species [7,11,13]. It was within the range reported for leaves of some fodder trees [21,22] including Acacia nilotica, A. tortilis and Ziziphus spina-christi [3,25] and browse forages [23].…”

“…The neutral detergent fibre content of the cell wall (i.e., the insoluble) ranged from 329.9 g kg −1 DM in T. indica to 636.5 g kg −1 in Z. spina-christi indicating that the latter is the richest in its energy content compared to the others. The NDF contents are lower when compared with some reported studies for browse forages [23], comparable to higher with the content for some fodder species reported by Mokoboki et al [7], Mekonnen et al [11] and Sandoval-Castro et al [21], and much higher to Moringa species [13].…”

“…These include laboratory analysis of proximate, detergent fibre, in vitro digestibility fractions, anti-nutritional factors and major mineral constituents' determination [6][7][8]. Nutritional analysis conducted so far in this regard in Ethiopia dealt with only a few exotic tree legumes and some indigenous species [9][10][11][12][13], and most of the browse resources in the pastoral and agro-pastoral regions remain unexplored.…”

Background: Indigenous tree and shrub species are critical feed resources for the pastoralist and agro-pastoralist areas in Ethiopia. Nutritional and mineral composition of seven high priority leguminous indigenous tree species, (Acacia nilotica, Acacia tortilis and Tamarindus indica) and non-leguminous species (Berchemia discolour, Cordia sinensis, Dobera glabra and Ziziphus spina-christi) were characterized to inform decisions on the species utilization and domestication. Method: Data on a total of 17 nutritional factors were generated on leaf samples from 10 to 12 trees per species following standard lab procedures. Descriptive statistics, one-way analysis of variance among species and types, and Spearman correlations between the nutritional factors were conducted. Results: Result showed that there were significant differences among the species for all chemical compositions and mineral contents except for iron. The leguminous species had significantly higher mean dry matter, organic matter, lignin and in vitro digestible organic matter in dry matter, whereas the non-leguminous species had significantly higher mean total ash, neutral detergent fibre, acid detergent fibre and hemi-cellulose. Similarly, the leguminous species had significantly higher mean iron, whereas the non-leguminous species had significantly higher mean macro-minerals, Mn and Zn. Across all the species and samples analysed, the majority (69%) of the paired comparisons revealed significant associations among the chemical compositions and digestibility, whereas nearly 54% of the comparisons were significant among the mineral contents. Conclusions: We conclude that the tree species investigated are important sources of protein, energy and minerals, and utilization and domestication should target both the leguminous and non-leguminous types.
