The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Animal Health Management
Effect of Crude Extracts of Viscum Verrocosum Treatment on Nematode Parasite Faecal Egg Count in Female Tswana Goats
Abstract:
The present study was carried out at Notwane Farm of
Botswana College of Agriculture with local Tswana goats. Goats
graze and browse on a mixture of Acacia savanna with broadleaved
middle layer trees with no or little supplementation.
Infestation with nematode parasites is one of the factors that
impinge on growth of goats and also increase healthcare costs.
Various concentrations of traditional medicine derived from
mistletoe (Viscum verrocosum) extracts were orally
administrated to nematode infested goats. The excreta of
control animals (dosed with distilled water) had significantly (P
< 0.05) high worm eggs than those dosed with an anthelmintic
drug (Valbazen) and crude extract of V. verrocosum at
concentration rates of 130, 260 or 500 g/l (1828, 913, 780, 1089
and 945epg respectively). There was also a highly significant
(P < 0.001) treatment x time interaction for faecal worm eggs
due to higher faecal egg counts, at various time points, from
control goats than other treatment groups. There was no
significant difference (P > 0.05) in live weight of goats from
different treatments probably indicating resilience of Tswana
goats to nematode parasites. This plant was previously found
to contain high concentration of condensed tannins which may
be responsible for its action on nematode parasites. This
preliminary dosing trial confirms previous studies on the efficacy
of V. verrocosum in reducing feacal egg count in Tswana
goats.
La présente étude a été réalisée à la ferme de Notwane du
Collège des Sciences Agronomiques du Botswana sur des
chèvres locales du Tswana. Des chèvres paissent et broutent
sur un mélange de savane des acacias faits des feuillus de
couche intermédiaire sans ou avec peu de supplémentation.
L’infestation par les parasites nématodes est l’un des facteursqui affectent la croissance des chèvres et qui augmentent
aussi les coûts des soins de santé. Diverses concentrations de
la médecine traditionnelle provenant des extraits de gui
(Viscumverrocosum) ont été administrées par voie orale à des
chèvres infestées de nématodes. . Les excréments des animaux
témoins (traités avec de l’eau distillée) avaient significativement
(P <0,05) plus d’oeufs de vers que ceux traités avec un
médicament anthelminthique (Valbazen) et un extrait brut de V.
verrocosum à des taux de concentration de 130, 260 ou 500 g /
l (1828, 913, 780, 1089 et 945epg respectivement). Il y avait
aussi un traitement hautement significatif (P <0,001) et une
interaction temporaire pour les oeufs de vers fécaux due à un
nombre plus élevé d’oeufs fécaux, à divers moments, des
chèvres témoins que les autres groupes de traitement. Il n’y
avait pas de différence significative (P> 0,05) de la charge utile
des chèvres de différents traitements sans doute indiquant la
résilience des chèvres de Tswana aux parasites nématodes.
Cette plante est reconnue de contenir une forte concentration
de tanins condensés qui peuvent être responsables de son action
sur les parasites nématodes. Cet essai de traitement préliminaire
confirme les études antérieures sur l’efficacité de V. verrocosum
dans la réduction du nombre des oeufs fécaux chez les chèvres
de Tswana.
