Research Project: SUSTAINABLE CONTROL OF

GASTROINTESTINAL NEMATODES IN SMALL RUMINANTS

Location: Dale Bumpers Small Farms Research Center,

Booneville, Arkansas

2007 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

reimbursable agreement between ARS and Fort Valley State

University. Additional details of research can be found in the

As such, objectives of this research relate to Component IV

(Grazing Management) of the NP205 action plan. This is the

second year of this project. A study was conducted with

mature goats grazing sericea lespedeza compared with other

forages for gastrointestinal nematode control and samples

are being analyzed. Preliminary analyses indicate that there

was a low frequency of deworming required for all treatments.

Another study was conducted with goats grazing curly dock or

mixed grasses for parasite control. There were no treatment

differences for variables examined. Use of copper oxide wire

particles was used for gastrointestinal nematode control, and

only one chronically anemic animal required any chemical

deworming. Trials on use of copper oxide wire particles in

goats is ongoing and a paper was published in Journal of

Animal Science. Communication between ARS and FVSU

occurred at meetings (October 2006 at Fort Valley State

University; February 2007 at the Southern Section ASAS

meeting in Mobile, AL; May 2007 at Virginia Tech) and by

regular (weekly or monthly) email.
