“…Present results are in concurrence with earlier reports, who have reported that CT are beneficial to ruminants at low concentration because they protect plant proteins from degradation in the rumen (Waghorn and Shelton, 1992;Wang et al, 1994;Dey et al, 2008;. Higher CT level (more than 5%) in the diet of ruminants adversely affect the intake and digestibility of forage (Perevolotsky et al, 1993). Rowe et al (1988) reported a reduction in apparent digestibility of OM across the whole digestive tract, but particularly in the abomasum of H. contortus infected sheep.…”

The experiment was carried out in 12 local adult male goats of average body weights (26.49±0.87, kg) and they were allocated in 3 groups (4 goats in each). Multi nutrient blocks (MNB) were supplemented in first two groups i.e. in T 1 (no infection) and T 2 (Haemonchus contortus infection @ 1500 larvae) group, while, condensed tannins (CT) containing multi nutrient blocks (MNB-CT) were supplemented in T 3 (H. contortus infection @ 1500 larvae) group in completely randomized block design during a feeding trial of 75 days. All the animals were fed concentrate mixture @ 100g/ day, adlib wheat straw and MNB or MNB-CT to meet their maintenance requirement. Daily intakes (kg W 0.75 ) of dry matter (DM), organic matter (OM), concentrate mixture, MNB, MNB-CT, wheat straw and digestibility of DM, OM, crude protein (CP) and acid detergent fibre (ADF) differed significantly (P<0.05) irrespective of groups. MNB-CT supplementation significantly (P<0.001) reduced serum urea (mg/dl) level and faecal egg counts (FECs) in T 3 group as compared to MNB supplemented (T 2 ) group. Serum proteins differed significantly (P<0.001) among groups. It may be concluded that MNB-CT supplementation indicates a positive impact on protein bioavailability and encouraging impact on nutrient utilization, biochemical constituents and health status of goats by lowering serum urea and FECs.

“…Condensed tannin concentrations greater than 5% adversely affect forage intake and digestibility (Perevolotsky et al, 1993;Silanikove et al, 1996). However, some reports from literature confirmed that ruminant animals are able to handle browse plants with tannin content below 100 g/kg DM (Gasmi-Boubaker et al, 2005) although the tolerance level may vary between animal species (Onwuka, 1992).…”

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.

“…Presumably the reason for the low intake of these shrubs was not poor nutritional quality (Rogosic et al, 2006b), but because they contained high concentrations of secondary compounds. High concentrations of tannins in Q. calliprinos (Perevolotsky et al, 1993) have been found to reduce preference for that shrub by sheep and goats. Tannins also limit the intake of strawberry trees (A. unedo) and holly oak (Q. ilex), dominant shrubs in Mediterranean maquis vegetation (Rogosic et al, 2006a(Rogosic et al, , 2006b.…”

“…The nutrient composition of these shrubs varies considerably (Rogosic et al, 2006b), ranging from low to intermediate diet quality. However, utilisation of the Mediterranean shrubs is often limited by secondary compounds such as tannins, terpenes and saponins (Perevolotsky et al, 1993;Silanikove et al, 1994;Rogosic et al, 2003Rogosic et al, , 2006aRogosic et al, , 2007Rogosic et al, , 2008. High concentrations of these components can adversely affect forage intake and animal health.…”

Maquis plant communities are one of the most varied vegetation types in the Mediterranean region and an important habitat for wild and domestic herbivores. Although the majority of these shrubs are nutritious, the secondary compounds are the main impediments that reduce their forage value. In five experiments, we determined the effect of supplementing the diets of goats with calcium hydroxide plus barley and with barley alone on their intake of five dominant shrubs (Quercus ilex, Erica multiflora, Arbutus unedo, Viburnum tinus and Pistacia lentiscus) of the Mediterranean maquis community. The combination of calcium hydroxide plus barley and barley alone increased the utilisation of Q. ilex, E. multiflora and P. lentiscus, while the intake of A. unedo and V. tinus was not statistically significantly different. Calcium hydroxide and barley (energy) enhance the use of secondary compound-containing plants, which may increase the production of alternate forages and create a more diverse mix of plant species in the Mediterranean maquis plant community.
