Two strains of obligately anaerobic cellulolytic bacteria designated as PS7 and PS8 (PS for porcupine species) were isolated from hindgut fluid of a crested porcupine (Hystrix cristata). The rates of cellulose degradation, total volatile fatty acids, and gas production from cellulose by the isola...

The effect of five multipurpose trees (MPTs), Acacia angustissima, Acacia saligna, Chamae-cytisus palmensis, Leucaena pallida and Sesbania sesban on ciliate protozoa was investigated in rumen cannulated Ethiopian sheeBoth entodiniomorphs and holotrichs were counted. The protozoa counts from S. se...

Effect of multipurpose tree (MPT) supplements on ruminal ciliate protozoa
Supplementation of basal diets with multipurpose trees (MPTs) increases essential nutrients available to rumen microbes, increases rate of passage of particulate matter by 23-53 percent and of liquid matter by 9-43 percent. Supplementing teff straw with graded levels of cowpea or lablab significa...

The role of legume forages as supplements to low quality roughages - ILRI experience
Nine different accessions of Sesbania sesban were examined for their toxicity to ciliate protozoa from sheep receiving a mixed grass hay-barley/fishmeal concentrate in Aberdeen, Scotland. Several accessions were much more toxic than those (ILRI 10865, ILRI 15036) identified and tested in a previo...

Influence of foliage from different accessions of the sub-tropical leguminous tree, Sesbania sesban, on ruminal protozoa in Ethiopian and Scottish sheep
Acacia angustissima has potential in agroforestry systems for forage production in tropical environments. However, feeding trials indicate that the leaves are potentially toxic. Signs of toxicity in sheep are similar to those presented by sheep fed flatpea (Lathyrus sylvestris) hay which contains...
Tannins limit the use of fodder trees as feed for ruminants. Removal of the effects of tannins would thus improve the nutritional quality of these trees. This prompted the study to evaluate the effect of rumen or faecal mixed cultures from different animals on tannin degradation. Tannin extracts,...

Four straight rods and three spherical bacteria were isolated using roll tubes inoculated with rumen fluid from sheep and goats and enriched with tannic acid. The isolates were characterized by morphology, products of fermentation and restriction fragment length polymorphism that indicated the co...

In most tropical countries poor nutrition limits ruminant productivity. The main feed resources include native pasture and crop residues, which are low in nitrogen (6.2-10.6 g/kg DM) and high in fibre (676-772 g/kg DM). Nutritional deficiencies of these feeds can be alleviated by supplementation ...
