Odenyo, A.A.[Managing the rumen to increase the supply of nutrients from fodder trees with multipurpose function]Managing the rumen to increase the supply of nutrients from fodder trees with multipurpose function

A study was carried out to determine if the protozoal fauna of indigenous African wild ruminants was different from that found in their domestic counterparts and if the animal's diet influenced the number and types of protozoa. Samples of rumen contents were collected in 1997 and 2001 from variou...

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,...

The capabilities of rumen fluid sources from indigenous African ruminants and hindgut fluid from zebra to ferment leaves of Acacia angustissima, Calliandra calothyrsus, Leucaena diversifolia, Leucaena leucocephala, Leucaena pallida, and Tephrosia bracteolata were evaluated to determine the presen...


Odenyo, A.A.McSweeney, C.S.Palmer, B.Negassa, D.Osuji, P.O.[In vitro screening of rumen fluid samples from indigenous African ruminants provides for rumen fluid with superior capacities to digest tannin-rich fodders]In vitro screening of rumen fluid samples from indigenous African ruminants provides for rumen fluid with superior capacities to digest tannin-rich fodders

There are conflicting Reports in the literature about the benefits of defaunation, the removal of ciliate protozoa from the rumen, in ruminant production. Ciliate protozoa are not essential for proper functioning of the rumen nor for the life of the host and that their contribution to microbial p...

Foliage from the tropical leguminous tree, Sesbania sesban, is toxic to rumen protozoa in vitro, due to materials present in a saponins-containing extract of the foliage (Newbold et al 1997). Suppression of protozoal numbers in vivo when S. sesban is added to the diet is either transient or non-e...

The experiment was carried out using a replicated (3x3) Latin square design with six sheep, to assess, the effect of supplementing maize stover fed ad libitum at three levels (100, 150 or 200 g) of Leucaena diversifolia. The sheep had an initial live weight of 26.4 kg (+ or -) 1.78 kg. In each pe...


Hindrichsen, I.K.Osuji, P.O.Odenyo, A.A.Madsen, J.Hvelplund, T.[Effects of supplementation of a basal diet of maize stover with different amounts of Leucaena diversifolia on intake, digestibility, nitrogen metabolism and rumen parameters in sheep]Effects of supplementation of a basal diet of maize stover with different amounts of Leucaena diversifolia on intake, digestibility, nitrogen metabolism and rumen parameters in sheep
