Handbook of Equine Parasite Control – review
Like it or not, the days of calendar-based worming programs are behind us.
One tin dismiss imagine to a greater extent than or less Equus caballus owners, used to grabbing their dewormer of alternative in addition to firing it downwardly the throats of their horses at regular intervals, powerfulness survive a tad grumpy over the whole affair.
I mean, what could survive easier than buying a bunch of wormers every few weeks in addition to dispensing the joy?
Parasitologists instantly believe this so-called interval-based dosing plan in addition to its derivatives accept been principal contributors to electrical flow levels of drug resistance inwards Equus caballus establishments.
The overwhelming bear witness suggests that the way frontward is evidence-based parasite command (EBPC), authors Craig Reinemeyer in addition to Martin Nielsen explicate inwards their novel book, “Handbook of Equine Paraside Control“.
By implementing such a program, Equus caballus owners volition speedily position which of their horses are most vulnerable to heavy parasite burdens in addition to many may survive surprised at how they cut back their operate of dewormers spell nonetheless keeping parasite numbers inwards check.

In doing so, they volition survive eliminating unnecessary operate of deworming drugs in addition to doing their fleck against the rising of drug resistance amidst parasites.
Reinemayer in addition to Nielsen, both equine parasitologists, tell evidence-based parasite command is a relatively novel evolution inwards equine medicine, which to a greater extent than or less vets in addition to Equus caballus possessor may nonetheless encounter every bit “new-fangled”.
However, Equus caballus vets are instantly to a greater extent than receptive to the approach, in addition to their mass is their endeavor to address that involvement past times offering practical advice in addition to logical recommendations, based on the latest science.
Change, they say, does non come upwards easily.
“The authors human face the challenge of changing a mindset, of overcoming 4 decades of tradition, literally tens of millions of episodes of implementation, in addition to competing recommendations from the marketing departments of every pharmaceutical companionship amongst a Equus caballus inwards the race,” they write.
“Change is painful but necessary, in addition to progress inwards parasite command volition survive measured i practitioner in addition to i Equus caballus possessor at a time.”
The authors accept successfully distilled a pregnant trunk of textile into a 210-page mass containing a well-balanced mix of the latest science, together amongst practical advice for implementing evidence-based programs.
The get-go subdivision delves into internal parasites in addition to factors affecting their transmission, neatly summarizing the likes of their biology, life cycles, environmental factors, in addition to aspects of the host in addition to the parasite that touching on transmission.
It is surprising what scientific discipline cannot enjoin us virtually to a greater extent than or less of these organisms, signalling that time to come inquiry nonetheless has pregnant range to amend parasite management inwards horses.
Take encysted pocket-size strongyles, for example. At a certainly phase inwards their life cycle they burrow into the wall of the digestive tract for a menstruation ranging from a few weeks upwards to 2.5 years.
They are constantly surrounded past times a pocket-size mass of clear fluid, but the properties of this liquid are virtually unknown.
Once mature, the adult larvae interruption through the cyst in addition to into the digestive tract, doing impairment to the gut wall inwards the process, to survive ejected dorsum into pasture. Relatively lilliputian is known of the mechanical in addition to chemic agency past times which the larvae create this.
The minute subdivision explains the principles of parasite control, dealing non solely amongst anthelmintic use, but non-chemical agency of parasite control, such every bit pasture hygiene in addition to quarantine practices.
This subdivision outlines the anthelmintic drugs available in addition to the normal handling regimens, from interval dose programs, almost invariably used without diagnostic testing to assess worm burdens, to to a greater extent than strategic dosing – again, without testing for worm burdens. It likewise explains low-dose daily treatments, which may survive responsible for high levels of pyrantel pamoate/embonate resistance inwards North America.
The 3rd subdivision delves into diagnosing in addition to assessing parasitologic information, the tests for assessing worm burdens in addition to the operate of fecal egg counts to let on resistance to anthelminitics.
By now, the yoke accept set the groundwork to lay out a synopsis for evidence-based parasite control.
They lay out the scientific arguments for this approach inwards compelling fashion.
“When veterinary practitioners in addition to Equus caballus owners plough to parasitologists for advice in addition to guidance, the sense unremarkably results inwards frustration, annoyance, or wholesale rejection of whatever ‘new fangled’ recommendations,” the yoke admit.
“Those involved amongst the practical aspects of equine management typically essay uncomplicated in addition to straightforward advice, in addition to parasite command inwards horses has long been only that – a one-size-fits-all, generic recipe that solely considers a drug in addition to calendar.
“Unfortunately, evidence-based parasite command is to a greater extent than complicated than most pragmatists suspect, in addition to this mass has attempted to explicate why.”
An evidence-based approach relies on the operate of diagnostic testing earlier applying the strategic operate of the correct anthelmintics to attain iii things:
- Minimize the conduct a opportunity of parasitic disease.
- Reduce infection pressure.
- Maintain in addition to prolong the effectiveness of existing drugs.
The concluding subdivision of the mass is a practical goldmine of information, where the authors push clit xx real-life instance histories. They outline the number or work inwards each case, in addition to pose the questions raised inwards each circumstance. They in addition to thence explicate their thinking on the number in addition to the answers.
It is a dandy approach, providing easily digestible information on a broad hit of practical parasite problems.
The instance histories are an eclectic mix, ranging from dealing amongst a riding-school possessor sceptical virtually the accuracy of egg counts (subsequent testing of 31 horses on iii occasions showed no extreme variability – horses that had higher fecal eggs counts inwards the get-go tests tended to proceed inwards the same vein for afterward tests, in addition to horses amongst lower counts tended to rest low).
There are likewise instance histories involving private horses – i amongst repeated colic, a foal amongst diarrhea, to a greater extent than or less other amongst oral lesions.
In all, the cases supply a dandy mix of to a greater extent than or less pretty interesting scenarios.
One suspects that the labor confronting Reinemayer in addition to Nielsen, inwards assessing what was worthy of inclusion inwards the handbook in addition to what should survive left out, was non easy. The yoke did an first-class labor inwards that regard, producing a handbook which is logically structured in addition to lays out what veterinarians, technicians in addition to others amongst an involvement inwards worm command demand to know to position together a parasite command plan using the latest principles.
The mass is beingness promoted every bit a companion for equine veterinary practitioners, veterinary students, equine veterinary technicians in addition to nurses, researchers inwards equine parasitology, Equus caballus owners, in addition to farm in addition to stable managers.
Each chapter concludes amongst the references to relevant scientific papers, should equine professionals select to delve further.
Nielsen told Horsetalk: “The target reader would survive veterinary practitioners, laboratory in addition to veterinary technicians, farm managers in addition to other equine professionals. The ordinary Equus caballus possessor may let on it a fleck difficult to read, but a lot accept dandy involvement inwards parasite command in addition to would belike let on the mass useful.”
That said, a keen Equus caballus possessor amongst a particular involvement inwards parasite command volition let on it a valuable beginning of useful information, such every bit the management issues inwards dealing amongst “lawns in addition to roughs” inwards pasture, the merits of harrowing pastures, in addition to pasture rotation strategies, permit lonely the sensible operate of drugs to hold worm numbers nether contol.
Reinemeyer in addition to Nielsen are to survive congratulated for producing the book, having identified a clear demand for such a handbook. It is the variety of pro-active activity that volition promote much-needed alter – one practitioner in addition to i Equus caballus possessor at a time.
Craig R. Reinemeyer graduated from the Ohio State University College of Veterinary Medicine inwards 1976, in addition to spent five years inwards mixed brute practise earlier returning to OSU to pursue a PhD inwards veterinary parasitology. He was a faculty fellow member of the University of Tennessee College of Veterinary Medicine from 1984 to 1998, in addition to served every bit the President of the American Association of Veterinary Parasitologists from 2003 to 2004. In 1997, Dr. Reinemeyer founded East Tennessee Clinical Research, a contract inquiry organization that conducts pharmaceutical studies to facilitate the evolution of novel veterinary drugs. ETCR’s efforts accept contributed to the blessing of several currently marketed anthelmintics for horses, cattle, in addition to pets.
