Research Project: SUSTAINABLE CONTROL OF

GASTROINTESTINAL NEMATODES IN SMALL RUMINANTS

Location: Dale Bumpers Small Farms Research Center,

Booneville, Arkansas

2008 Annual Report

1a.Objectives (from AD-416)

Objectives are to.

1)increase level of adoption of available sustainable

gastrointestinal nematode control strategies in the

southeastern USA and Puerto Rico,.

2)investigate use of existing and developing novel nonchemical approaches for controlling gastrointestinal nematode

in small ruminants, and.

3)develop and test sustainable small ruminant parasite

control systems integrating conventional and novel

gastrointestinal nematode control strategies.

1b.Approach (from AD-416)

Producer and advisor workshops will be held on smart

drenching and use of FAMACHA that include education and

training on these integrated programs (this will be conducted

by all cooperators). The following will be examined:.

1)test the anthelmintic potential of condensed tannins (CT) in

sericea lespedeza (SL) as part of the small ruminant diet

(conducted by ARS-AR for lambs, LSU for breeding ewes, FVSU

for goats),.

2)test the potential anthelmintic effect of copper oxide wire

particles (COWP) on H. contortus infection (conducted by ARSAR for lambs, LSU for breeding ewes, FVSU for goats),.

3)test potential of using the FAMACHA system for identification

of GIN-resistant sheep and goats (conducted by all

cooperators),.

4)test the potential of Duddingtonia flagrans as a biological

control agent against parasitic nematodes of small ruminants

(conducted by LSU and FVSU),.

5)test H. contortus hidden gut antigen as a means to

vaccinate goats against infection (conducted by LSU and

FVSU),.

6)experiments using combinations of conventional

(anthelmintic treatment) and novel (FAMACHA, CT-containing

forages, COWP, nematode-trapping fungi, vaccination and

breeding for resistance) control technologies will be conducted

to determine possible synergistic or antagonistic effects

between the different control methods being evaluated and

cost-benefit analysis will be used to determine the economic

feasibility of each of the integrated control programs tested

within this project (initially conducted by ARS-AR, LSU, FVSU

and on-farm testing will be conducted by all cooperators).

3.Progress Report

An investigation in efficacy of copper oxide wire particles

between kids and lambs revealed that reduction in fecal egg

counts was more rapid in lambs than kids, but was highly

effective for both species. However, another study indicated

that copper oxide wire particles were not effective directly

after weaning in lambs and kids. A third study indicated that

copper oxide wire particles mixed in feed may be more

effective than in a bolus for control of Haemonchus contortus

in goats. These data are being prepared for publication.
