Topic:Deworming
Deworming is a management practice aimed at controlling internal parasites in horses. It involves the administration of anthelmintic drugs to reduce the burden of parasitic worms such as strongyles, ascarids, and tapeworms. Effective deworming strategies are based on understanding the life cycles of parasites and the use of fecal egg counts to tailor treatment plans. This practice helps maintain horse health by preventing parasite-related issues such as colic, weight loss, and poor coat condition. This page compiles peer-reviewed research studies and scholarly articles that explore the efficacy, methodologies, and impacts of deworming protocols on equine health and management.
Ivermectin performance in horses diagnosed with equine endocrine disorders. Anthelmintic performance against equine cyathostomins can be evaluated by two different non-terminal measures; the Fecal Egg Count Reduction Test (FECRT) and the Egg Reappearance Period (ERP). Most available FECRT and ERP data have been determined in populations of young horses, and very little information is available from mature and senior horses. Furthermore, it is unknown how commonly occurring equine endocrine disorders such as Insulin dysregulation (ID) and Pituitary pars intermedia dysfunction (PPID) may interfere with these measurements, but it has been suggested that horses with these...
Worm control practices used by Thoroughbred horse managers in Australia: A national survey. This study assessed worm control practices used by Australian Thoroughbred farm managers with an online questionnaire survey. The questionnaire comprised 52 questions (close-ended: 44; open-ended: 8) about farm demography and general husbandry practices, farm managers' knowledge of gastrointestinal nematodes (GIN) and their importance, diagnosis, worm control strategies and anthelmintics, anthelmintic resistance (AR) and grazing management. Following the pilot survey, the link for the questionnaire survey was sent to all (n = 657) registered members of the Thoroughbred Breeders Australia on ...
Survey on sanitary practices and knowledge about infectious diseases among equine owners in the State of Rio Grande do Norte, Brazil. As the primary decision-maker about the health, nutrition, and well-being of their horses, owners' knowledge of correct management practices and clinical changes can potentially affect the immediate health of their horses, in addition to having an impact on the prevention of disease spread in the herd. The adoption of management practices to prevent the introduction and spread of pathogens depends on various factors, including demographics, awareness of the problem, perceived responsibility, previously held beliefs, and sociocultural norms. This study aimed to evaluate the health management pr...
Assessment of worm control practices recommended by equine veterinarians in Australia. This study aimed to assess Australian veterinarians' knowledge, perceptions and treatment strategies for worm control in horses with an online questionnaire. The questionnaire comprised 64 questions covering various aspects of: (i) veterinary practice; (ii) the veterinarian's knowledge of gastrointestinal nematodes (GINs) and the importance of parasites in different age groups of horses; (iii) the diagnosis and control of worms; (iv) anthelmintics and anthelmintic resistance (AR); (v) grazing management; and (vi) the means of communication and the discussion between veterinarians and their cli...
Characterization of gastrointestinal inflammatory cell type in equine glandular gastric disease. To compare small intestinal inflammation with gastric inflammation in horses with and without equine gastric glandular disease (EGGD), we evaluated endoscopic, macroscopic, and microscopic findings of the glandular stomach and microscopic findings of the small intestine. Methods: 36 horses. Methods: Horses underwent endoscopy and were scored for EGGD. After euthanasia, stomachs were collected and macroscopically evaluated. Normal pyloric mucosa, glandular lesions, and small intestinal (duodenum, mid-jejunum, and ileum) samples were collected and processed for microscopic examination. Cellular ...
Helminth infection in horses – a cross-sectional study from stables in Lower Silesia (Poland). Parasitosis in horses may be uncontrolled and expose breeders and owners to serious financial losses or, possibly, to the loss of animals. Therefore, the prevention and monitoring of the development of parasitic diseases should play an important role in the breeding process. The aim of this study was to confirm the influence of factors such as age, breed, herd size, deworming program, and type of anthelmintics, on the prevalence and intensity of parasites (helminths) in domestic horses in Lower Silesia. The study was carried out between August and November of 2020. The samples of horse feces w...
Severely Asthmatic Horses Residing in a Mediterranean Climate Shed a Significantly Lower Number of Parasite Eggs Compared to Healthy Farm Mates. The relationship between helminth infection and allergic diseases has long intrigued the scientific community. This interaction was previously studied in a horse family with high incidence of severe equine asthma and in non-related severely asthmatic horses from equine hospital referrals in Switzerland. Our aim was to determine if this interaction would also be observed in a group of non-related client-owned severely asthmatic horses living in a Mediterranean climate and recruited through a first-opinion veterinarian group. Fecal samples from severe equine asthma-affected and healthy horses li...
Selective Anthelmintic Treatment in Horses in Sweden Based on Coprological Analyses: Ten-Year Results. In Sweden, routine deworming has been used for several decades; however, to slow down the development of anthelmintic resistance, selective treatment is currently recommended. As part of a monitoring programme, equestrian premises submitted faecal samples to the National Veterinary Institute (SVA) twice per year between 2008 and 2017. Analyses for strongyles (small and large), tapeworms and ascarids, followed by premise-specific advice regarding deworming and parasite control strategies, were provided. In total, 43,330 faecal samples, collected from 26,625 horses on 935 premises in springtime ...
Helminths and their management in Swiss Army horses: differences between riding horses and pack horses evidence the need of improvement. Intestinal helminth management in horses has both clinical and epidemiologic relevance, in additional association with anthelmintic resistance. The Swiss Army employs military owned riding horses and privately owned pack horses, which are brought together for service periods up to 12 weeks. We compared husbandry conditions and intestinal helminth management of both groups via questionnaire and analysed faecal samples of 53 riding horses and 130 pack horses using combined sedimentation/flotation, the McMaster method and larval cultures. Riding horses only had cyathostomin infections (prevalence...
Feasibility of selective anthelmintic therapy to horses in tropical conditions: the Cuban scenario. For the past several decades, selective anthelmintic therapy (SAT) has been recommended in temperate climate countries for controlling gastrointestinal parasites in horses. However, the feasibility of this approach in tropical climates remains unknown, given the very different parasite transmission patterns and a larger representation of working equids. The aim of this study was to evaluate the bio-economic feasibility of SAT in horses kept under tropical conditions of Camagüey, Cuba. Fecal egg counts were determined from 794 adult horses and used for evaluating three different putative treat...
Apparent Digestibility of Nutrients, Blood Parameters and Body Development of Dewormed and Not Dewormed Weanlings. Weanlings undergo rapid body development in the first year of life and, in this period, are more susceptible to helminth infection that can impair their growth. The objective of this study was to compare the apparent digestibility of nutrients, blood parameters, and body development of deworming and not deworming weanlings. Fourteen Mangalarga Marchador weanling colts, on a farm in Northern Minas Gerais, Brazil, were divided into two groups: dewormed (D) and not dewormed (ND) groups. The weanlings were kept separately for 3 months in two pastures of Cynodon nlemfuensis cv. African Star Grass....
Outcome of tactile conditioning of neonates, or “imprint training” on selected handling measures in foals. Behavioural reactions to selected handling procedures were compared between conditioned, or imprint-trained, and untrained foals raised on the same farm. Nineteen randomly chosen healthy foals were imprint trained at birth and 24 h later (Group A). Twenty-one similar foals that were not imprint-trained served as age-matched controls (Group B). Training began within 10 min of birth and consisted of touch desensitization by gentle rubbing. Each tactile stimulus was repeated 30-50 times over 45-60 min, until the foal no longer resisted the procedure and appeared relaxed. The procedure was then re...

Methods: Each month for 12 months, participating veterinarians were sent forms to collect information on 1 horse with colic and 1 horse that received emergency treatment for a condition other than colic, information collected included signalment, farm management and characteristics, diet, medical and preventive medical factor...
Patterns of health maintenance on Michigan equine operations. Data from two 12 month prospective monitoring programs that followed management, economics and animal health from randomly-sampled equine operations in Michigan were used to determine patterns of health maintenance. Health maintenance measures were grouped, and average uses per year were computed for the most-common measures reported: respiratory, Potomac Horse Fever, neurological and multiple-system vaccinations, deworming, and general farrier work. Factors examined for potential association with health maintenance measure use were numbers of equids and horse-days on the operation, average ag...
[Testing of a deworming scheme for horses]. In 1983 and 1984 the effect of a deworming scheme, in which horses were treated at turn out and 4 and 8 weeks later, on the egg output, larval differentiation, weight gain, herbage infestation and in 1984, the percentages of some serum proteins were tested. In 1983 the experiment was done with 42 mares, 54 two year old male horses and 42 male yearlings, kept in groups with permanent or rotational grazing. In 1984 only 90 male yearlings were investigated. In 1983 albendazole and ivermectin were used, 1984 ivermectin. The results of the faecal examinations showed that after ivermectin treatment ...
