Drug resistance to multiple drugs and sometimes to all available drugs in parasites of goats is extremely common. In order to deliver effective treatments to their animals, it is recommended that producers learn which dewormers still work on their farms by doing fecal egg count reduction tests (FECRT, comparing before and after fecal egg counts) or having a DrenchRite® larval development assay (LDA) done. Several land grant universities now offer low cost ($5/sample) fecal egg counting for this purpose. For more information, go to https://www.wormx.info/lowcostfec . For information about the cost and availability of the DrenchRite test, send an email to email@example.com .
To improve the effectiveness of deworming treatments, it is now recommended that goats be given combination treatments. A combination treatment is when you give drugs from different classes to the same animal at the same time. It is important not to mix the different drugs together as they are not chemically compatible.They should be given separately, but can all be given at the same time, one right after the other. It is always recommended to treat goats selectively given their individual need for treatment based on FAMACHA© score and/or the Five Point Check©. Sometimes performance (ADG, milk production, litter size) is used as a criterion for deworming. This recommendation is even more important when using drugs in combination. If all animals in the herd are treated, resistance to the dewormers will develop rapidly, and if using a combination, there will be nothing left to use when this happens.

Reduced survival of lambs from maiden ewes exposed to mature ewes pre-lambing
S.M. Robertson, M.B. Allworth, M.A. Friend
Vol. 151, p11–15
The suboptimal survival of new-born lambs is a major source of reproductive inefficiency, is often lower in maiden (first-lambing) compared with multiparous ewes, and this may be associated with poor maternal behaviour due to inexperience. This study examined whether the survival of lambs from maiden ewes could be increased by exposing maiden ewes to multiparous lambing ewes in the month before lambing. Pregnant maiden Merino ewes (n = 446) which had been mated at 18 months of age were allocated to three replicates of two treatments.
We just got word of a great workshop coming up in just a few days. We hope some of you will be able to attend.
Objective: Discuss genetic selection strategies to identify parasite resistant individuals applicable for the conditions of the sheep and goat flocks of México and Latin America.
“Bridges between scientific advances and farm development”
by Hervé Hoste
This conference took place in Toulouse, France from March 24th to March 28th, 2013, and joined with a session of the COST Action FA0805 CAPARA on “Goat-Parasite Interactions: From Knowledge to Control”
Aims and Scope
Since the first meeting in Armidale (Australia) in 1995, the International Conferences on the Novel Approaches (NA) to the Control of Helminth in Livestock aimed at stimulating links between scientists and specialists of extension services from developed, emerging and developing countries on the specific topic of the control of helminthes in livestock. The main objectives of the COST (European Cooperation in Science and Technology) Action CAPARA (Goat-parasite interactions: from knowledge to control) FA0805 are similar to those of the Novel Approaches meeting. However, as indicated by its title “Goat-Parasite Interactions: From Knowledge To Control” this COST Action is specifically dedicated to caprine production.
Both the Novel Approaches Conferences and the CAPARA Cost Action FA0805 are frameworks where the importance to maintain or expand links between scientific advances and extension services and end-users is underlined. Last but not least, this conference was also supported by the International Goat Association.
The International Goat Association promotes goat research and development for the benefit of humankind, to alleviate poverty, to promote prosperity and to improve the quality of life.
