Topic:Herd Management
Herd management in horses involves the organization and oversight of groups of horses to ensure their health, welfare, and productivity. This encompasses various practices, including the arrangement of living conditions, feeding strategies, health monitoring, and social dynamics within the group. Effective herd management requires understanding the natural behaviors and social structures of horses, which can influence their physical and mental well-being. Factors such as pasture management, rotational grazing, parasite control, and vaccination schedules are integral to maintaining a healthy herd. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, challenges, and outcomes associated with herd management in equine populations.
Transmission of endoparasites in horse foals born on the same pasture on a farm in central Kentucky (1996-1999). Research carried out during the last 4 years (1996-1999) of an 11-year study of the prevalence of internal parasites naturally transmitted to horse foals born on the same pasture on a farm in central Kentucky is presented here. Horses in this herd were not treated with any antiparasitic compound for over 20 years except for a replacement stallion in 1994. A total of 22 species, including 12 species of small strongyles, were recovered in the 4-year period. Transmission patterns of all species (n=35) of endoparasites recovered are compared for the 11-year study. Some of the changes were an incre...
Risk factors to tick infestations and their occurrence on horses in the state of São Paulo, Brazil. From December 1998 to March 1999, 40 stud farms were studied in the state of São Paulo, Brazil. During visits to farms, horses reared under grazing conditions were examined for the presence of ticks. On each farm visit, horse pastures were closely inspected and a questionnaire was given to the farm supervisor with the purpose of gaining information about ecological and management variables (independent variables) that could be associated with the presence and infestation levels of ticks on the farm (dependent variables). Three tick species were found during the study. Anocentor nitens, Amblyo...
The importance of ethology in understanding the behaviour of the horse. Domestication has provided the horse with food, shelter, veterinary care and protection, allowing individuals an increased chance of survival. However, the restriction of movement, limited breeding opportunities and a requirement to expend energy, for the benefit of another species, conflict with the evolutionary processes which shaped the behaviour of its predecessors. The behaviour of the horse is defined by its niche as a social prey species but many of the traits which ensured the survival of its ancestors are difficult to accommodate in the domestic environment. There has been a long asso...
Horses and the rural economy in the United Kingdom. The horse industry is large and varied, but until comparatively recently its contribution to the economy of the UK has been virtually ignored and this, together with the disparate nature and small size of the individual businesses involved, has resulted in a general lack of universally available data. What is undoubtedly true, however, is that the horse touches upon the professional and recreational aspects of many peoples' lives and that, without the horse, not only would a significant proportion of the rural working population be unemployed but many ancillary industries would have considerab...
Prevalence of antibodies to Brucella spp. in cattle, sheep, goats, horses and camels in the State of Eritrea; influence of husbandry systems. Samples from 2427 cattle, 661 goats, 104 sheep, 98 camels and 82 horses were screened for brucella infections by the Rose Bengal Test and positive reactors confirmed by the complement fixation test. In cattle, the highest individual seroprevalence was in dairy herds kept under the intensive husbandry system, with an individual prevalence of 8.2% and unit (herd) seroprevalence of 35.9%. This was followed by the pastoral husbandry system in the Western Lowlands with 5.0% individual but a higher unit (vaccination site) prevalence of 46.1%. The lowest was in the mixed crop-livestock system in the ...
Modelling the spread of a viral infection in equine populations managed in Thoroughbred racehorse training yards. A Monte Carlo model that simulates the management life cycle of a horse population in training on a Thoroughbred flat racing yard (i.e. stable) was developed for computer implementation. Each horse was characterised by several state variables. Discrete events at the horse level were triggered stochastically to reflect uncertainty about some input assumptions and heterogeneity of the horse population in a particular yard. This mathematical model was subsequently used to mimic the spread of equine influenza (EI) within a typical yard following the introduction of one or several infectious horses...
Effect of daily floor treatment with sodium bisulfate on the fly population of horse stalls. To determine application rate and effectiveness of sodium bisulfate to decrease the fly population in a horse barn environment. Methods: 12 privately owned farms in southeastern Pennsylvania. Methods: Application rates of sodium bisulfate were approximately 2.3 kg/stall, 1.1 kg/stall, and 0.5 kg/stall. Two or 3 stalls were treated, and 1 or 2 stalls were not treated (control stalls) at each farm. Farm personnel applied sodium bisulfate in treated stalls daily for 7 days. Fly tapes were hung from the same site in treated and control stalls. After 24 hours, the fly tape was removed, flies adheri...
Reproductive behavior of stallions and mares: comparison of free-running and domestic in-hand breeding. Based on observational studies comparing social organization and reproductive behavior of equids breeding under feral, semi-feral, and domestic conditions, a series of comparisons and findings on reproductive physiology and behavior are presented. Simple changes in management and handling of mares and stallions that can improve reproductive efficiency and fertility or that can overcome specific breeding problems are discussed.
[Health aspects and the duty of care in the rearing of young horses]. Future competition horses may suffer from health impairments due to complex or partial genetic components as well as to management faults in respects to keeping, feeding and health prophylaxis against infectious diseases. This health risks exist during the whole rearing period: from late pregnancy till far beyond weaning. Health impairments reduce trade value and practical use, and interfere with aspects of animal protection. In the field of breeding permission, first in stallions, applied research ist needed. For horse farms a praxis-oriented comprehensive advisory service should be establish...
Adaptive explanation in socio-ecology: lessons from the Equidae. Socio-ecological explanations for intra- and interspecific variation in the social and spatial organization of animals predominate in the scientific literature. The socio-ecological model, developed first for the Bovidae and Cervidae, is commonly applied more widely to other groups including the Equidae. Intraspecific comparisons are particularly valuable because they allow the role of environment and demography on social and spatial organization to be understood while controlling for phylogeny or morphology which confound interspecific comparisons. Feral horse (Equus caballus Linnaeus 1758) p...
Management factors affecting the risk for vesicular stomatitis in livestock operations in the western United States. To identify management factors affecting the risk of animals developing vesicular stomatitis (VS). Methods: Case-control study. Methods: Horses, cattle, and sheep with suspected vesicular stomatitis on 395 premises in Colorado, New Mexico, Utah, and Arizona. Methods: Data were collected during the VS outbreak of 1997. Diagnosticians interviewed livestock owners and completed a supplemental questionnaire. Cases were defined as those premises that had a completed questionnaire and had > or = 1 animal positive for VS. Control premises were all premises investigated that had a completed questionna...
Parasite diversity and anthelmintic resistance in two herds of horses. Diversity of parasite populations was compared between two herds of horses, one a regularly treated herd the other a feral herd which has bad no anthelmintic treatment for at least 25 years. Eggs obtained from fecal samples of both herds were tested for anthelmintic resistance by use of an in-vitro larval hatch/development assay (LDA), DrenchRite. A fecal egg reduction test was also performed with the domesticated herd using fenbendazole, pyrantel pamoate and ivermectin. Cyathostomes were the predominant group of worms present in both herds. Trichostrongylus axei was seen in both herds, but St...
Safe handling of large animals. The major causes of accidents with cattle, horses, and other grazing animals are: panic due to fear, male dominance aggression, or the maternal aggression of a mother protecting her newborn. Danger is inherent when handling large animals. Understanding their behavior patterns improves safety, but working with animals will never be completely safe. Calm, quiet handling and non-slip flooring are beneficial. Rough handling and excessive use of electric prods increase chances of injury to both people and animals, because fearful animals may jump, kick, or rear. Training animals to voluntarily coop...
A field survey on the distribution of strongyle infections of horses in Sweden and factors affecting faecal egg counts. Faecal egg counts were performed during the first quarter of 1995 on samples from 1183 horses of varying breeds, ages and gender on 110 farms in 3 regions of Sweden. The majority of the horses had been treated with ivermectin or pyrantel when stabled the previous autumn. The risk of reinfection with strongyles between treatment and sampling was therefore considered to be minimal. Consequently, the results reflect primarily the occurrence of worms originating from inhibited strongyle larvae refractory to anthelmintic treatment. A total of 922 (78%) individuals were found to shed strongyle eggs,...
Fertility of Shetland pony stallions used in different breeding systems: a retrospective study. In horses reproductive performance is usually expressed as the foaling rate. This rate ranges from 40% to 80%. Three major factors contribute to this variation namely, the stallion, the mare and management. In this study, the performance of Shetland ponies kept in three different breeding systems was investigated retrospectively. In one breeding system, the stud farmer travelled with his stallion (n = 9) to the mare (system 1) while in another system, the stallion (n = 3) stayed at the stud farm and the mares came to the stallion (system 2). The last system was pasture breeding (system 3; n = ...
[Marking of horses]. The author informs on up to date identification methods of horses. The implantation of passive transponders is a practicable method for marking of horses. Because it gives less pain to horses, this method is to prefer. Stress inflicted on horse is minimal, it compares to a intramuscular injection. The reliability of the system in use has so far been very high. Members of ISO have voted overwhelmingly in favor of a standard for electronic identification of animals. From now on, countries and user organizations can make use of this technique to identify animals and if used can rely on the fact t...
