Topic:Working Horses

Working horses are equines specifically trained and utilized for various tasks such as agriculture, transportation, and other labor-intensive activities. These horses are integral to certain industries and communities, providing physical labor and support. The category of working horses includes draft horses, carriage horses, and those used in logging or ranch work. Their management involves considerations of nutrition, health, and welfare to ensure their ability to perform tasks efficiently. This page gathers peer-reviewed research studies and scholarly articles that explore the roles, management practices, and welfare concerns associated with working horses, as well as their impact on human economic activities.
Articular fetlock injuries in exercising horses.
The Veterinary clinics of North America. Equine practice    March 4, 2008   Volume 24, Issue 1 117-132 doi: 10.1016/j.cveq.2007.11.011
Santschi EM.Articular injuries to the fetlock joint can be categorized as injuries to the soft tissues (synovium, ligaments, cartilage) or bone (third metacarpus/metatarsus, first phalanx, proximal sesamoids). This article focuses on the traumatic injuries to the cartilage and bone from anatomic, functional, and pathophysiological perspectives. An understanding of fetlock motion and loading will assist clinicians in the diagnosis, treatment, and, most importantly, prevention of fetlock injury in working horses.
Trypanosomosis in The Gambia: prevalence in working horses and donkeys detected by whole genome amplification and PCR, and evidence for interactions between trypanosome species.
BMC veterinary research    February 20, 2008   Volume 4 7 doi: 10.1186/1746-6148-4-7
Pinchbeck GL, Morrison LJ, Tait A, Langford J, Meehan L, Jallow S, Jallow J, Jallow A, Christley RM.The Gambia has an increasing population of equidae largely used for agriculture and transportation. A review of cases at The Gambian Horse and Donkey Trust (GHDT) indicated that a common reason for presentation is a poorly defined medical condition often attributed to trypanosomosis. There are few reports describing the prevalence or the range of clinical signs associated with infection with different species of trypanosomes in horses and donkeys, but given the importance of these animals, the role of trypanosomosis requires investigation. Results: In total 241 animals from the Central River D...
The physiological demands of horseback mustering when wearing an equestrian helmet.
European journal of applied physiology    January 5, 2008   Volume 104, Issue 2 289-296 doi: 10.1007/s00421-007-0659-5
Taylor NA, Caldwell JN, Dyer R.The hottest months on northern Australian cattle stations are from September to November, and it is during these months that horseback cattle mustering occurs. Stockmen wear clothing that restricts heat loss, and protective helmets have recently been introduced. Anecdotal evidence points to the possibility that helmets may increase the probability of developing heat illness, or reducing workplace performance. In this project, we quantified the working (thermal) environment on such cattle stations, and measured the metabolic demands on, and concurrent physiological strain in stockmen during mus...
Occurrence of antibodies against Leptospira spp. in horses of the urban area of Londrina, Paraná, Brazil.
Revista do Instituto de Medicina Tropical de Sao Paulo    November 21, 2007   Volume 49, Issue 5 327-330 doi: 10.1590/s0036-46652007000500010
Hashimoto VY, Gonçalves DD, Silva FG, Oliveira RC, Alves LA, Reichmann P, Muller EE, Freitas JC.A total of 320 horses were studied in this paper, both male and female, between two and 17 years of age, which were used for traction of wagons in the urban area of the municipality of Londrina (PR). These animals were kept, after their daily work, in abandoned areas or plots, in the outskirts of the urban area of the city. When these animals were attended by the veterinarians, between 1996 and 2005, none of them presented symptoms suggesting leptospirosis. The most frequent reasons for the visit were loss of weight, unwillingness for work, parasitism, laminess, and wounds. Microscopic Seroagg...
Equine histoplasmosis: treatment trial in cart horses in Central Ethiopia.
Tropical animal health and production    November 11, 2007   Volume 40, Issue 6 407-411 doi: 10.1007/s11250-007-9099-9
Hadush B, Ameni G, Medhin G.Therapeutic effects of Sodium Iodide (NaI), Potassium Iodide (KI), ground berries of "Endod" (Phytolacca dodecandra) and Penstrip were evaluated on 70 cases of equine hitoplasmosis (EH). Response to each treatment was assessed using clinical examination of the lesions. Statistically significant difference (P = 0.0036) in therapeutic effect was observed among the different remedies. Cases treated either with a combination of NaI and Penstrip (F = 6.34, P = 0.004) or "Endod" and Penstrip (F = 3.64, P = 0.031) demonstrated significant response. The difference in response to treatment between earl...
Risk factors for strap-related lesions in working donkeys at the World Heritage Site of Petra in Jordan.
Veterinary journal (London, England : 1997)    September 14, 2007   Volume 178, Issue 2 263-271 doi: 10.1016/j.tvjl.2007.07.014
Burn CC, Pritchard JC, Farajat M, Twaissi AA, Whay HR.A risk analysis was undertaken in an attempt to improve improvised rump straps on donkeys carrying tourists at the World Heritage Site at Petra, Jordan. Tail-base lesions were identified in 63 of the 86 donkeys. Observations and questionnaires were used to collect data relating to the straps, donkey health and human attitudes. The worse lesions were associated with padded rather than unpadded straps, if tightly fitted. Padding could be a cause of, or a response to lesions, but results suggest that it did not effectively aid healing. Significantly worse lesions occurred with unclean than with c...
Delivery of health and husbandry improvements to working animals in Africa.
Tropical animal health and production    August 9, 2007   Volume 38, Issue 2 93-101 doi: 10.1007/s11250-006-4363-y
Pearson RA, Krecek RC.Problems have been identified in the delivery of extension messages about the maintenance of healthy and well-fed working animals. The different factors that need to be considered in developing effective disease control and prevention programmes for working oxen and equids including vector-borne diseases, helminth disease, and vaccination programmes have been reported and discussed and experiences in improving husbandry including footcare, harness, and worm management reported. Most draught animals are owned by people who lack the financial means to pay for or to access the information needed ...
Hepatitis E virus infection in work horses in Egypt.
Infection, genetics and evolution : journal of molecular epidemiology and evolutionary genetics in infectious diseases    October 12, 2006   Volume 7, Issue 3 368-373 doi: 10.1016/j.meegid.2006.07.007
Saad MD, Hussein HA, Bashandy MM, Kamel HH, Earhart KC, Fryauff DJ, Younan M, Mohamed AH.Hepatitis E virus (HEV) is an important cause of hepatitis among young Egyptian adults with high seroprevalence rates seen in both rural areas of the Nile Delta and in suburban Cairo. Because natural antibodies to HEV have been detected in animals and zoonotic transmission is postulated, we surveyed work horses in Cairo for evidence of HEV exposure and viremia. Sera from 200 Cairo work horses were tested by ELISA for the presence of IgG anti-HEV antibody revealed a seropositivity of 13%. Among 100 samples processed for detection of viral genome by means of nested polymerase chain reaction (N-P...
Validity of a behavioural measure of heat stress and a skin tent test for dehydration in working horses and donkeys.
Equine veterinary journal    September 22, 2006   Volume 38, Issue 5 433-438 doi: 10.2746/042516406778400646
Pritchard JC, Barr AR, Whay HR.Dehydration and heat stress are serious welfare issues for equids working in developing countries. There is a lack of any standardised method or validated interpretation of the skin tent test in horses and donkeys. Owners of dehydrated and heat-stressed animals often depend on veterinary examination for identification of these conditions, leading to delays in treatment and unnecessary reliance on external sources to effect welfare improvement. Objective: To validate a standardised skin tent test for dehydration and a behavioural measure of heat stress in working equids; and to examine the effe...

Ameni G.A study was conducted between January 2003 and June 2004 on 19,082 carthorses in 28 towns in Ethiopia to investigate the epidemiology of equine histoplasmosis (EH). Clinical and microscopic examinations were used and an overall prevalence of 18.8% (3579/19082) was recorded. Statistically significant (P<0.001) differences was observed in the average prevalence with high, medium, and low prevalence categories. The highest prevalence (39%) was recorded at Mojo while the lowest (0.0%) was recorded at five towns, namely, Agaro, Bokoji, Debre Berhan, Dinsho, and Sagure. The prevalence of EH was n...
[Evaluation of the quality of husbandry of Franches-Montagnes horses in their breeding farms].
Schweizer Archiv fur Tierheilkunde    May 18, 2006   Volume 148, Issue 4 191-197 doi: 10.1024/0036-7281.148.4.191
Ionita JC, Poncet PA, Doherr MG, Steiger A.The quality of husbandry of Franches-Montagnes horses (FM) in Switzerland is evaluated on the basis of an investigation carried out in 2002 by the Swiss FM breeding federation. Questionnaires were sent to 3500 of its members and the results include data from 968 breeding enterprises, housing a total of 3965 FM: 46.1% were breeding mares (61.0% with foal at foot), 26.5% young stock, 1.3% stallions and 26.0% non breeding stock (74.6% of which were pleasure horses and 25.4% working horses). 57.6% of the FM were housed in individual boxes with or without permanent outdoor access, 25.4% were hold i...

Assessment of the welfare of working horses, mules and donkeys, using health and behaviour parameters.
Preventive veterinary medicine    March 16, 2005   Volume 69, Issue 3-4 265-283 doi: 10.1016/j.prevetmed.2005.02.002
Pritchard JC, Lindberg AC, Main DC, Whay HR.Working animals provide an essential transport resource in developing countries worldwide. Many of these animals are owned by poor people and work in harsh environments, so their welfare is a cause for concern. A protocol was developed to assess the welfare of working horses, mules and donkeys in urban and peri-urban areas, using direct observation of health and behaviour parameters. In this study, 4903 animals used for draught, pack and ridden work in Afghanistan, Egypt, India, Jordan and Pakistan were assessed between December 2002 and April 2003. The data showed that donkeys were more likel...
[Housing and use of horses in Switzerland: a representative analysis of the status quo].
Schweizer Archiv fur Tierheilkunde    August 15, 2002   Volume 144, Issue 7 331-347 doi: 10.1024/0036-7281.144.7.331
Bachmann I, Staᆲher M.Out of a representative sample of 1861 Swiss horse yards, 622 horse keepers (35.2%) with 2536 horses, ponies and donkeys sent back a questionnaire about general farm characteristics, their horse-specific training, horse stock, housing conditions, intraspecific social contacts, feeding, ability to move freely, use of the horses and management. 83.5% of horses were kept individually (thereof 18.3% tethered, 32.3% in a loose box indoors, 28.4% in a loose box outdoors, and 4.5% in a loose box with permanent access to a paddock or an individual pasture), and 16.5% lived in group housing systems. 36...
Common vetch (Vicia sativa) for improving the nutrition of working equids in Campesino systems on hill slopes in Central Mexico.
Tropical animal health and production    April 24, 2002   Volume 34, Issue 2 169-179 doi: 10.1023/a:1014274308054
Velázquez-Beltrán LG, Felipe-Pérez YE, Arriaga-Jordán CM.Campesino systems on hill slopes in Central Mexico rely on equids for multiple activities and have a problem in adequately feeding them. A participatory trial was conducted to evaluate the inclusion of common vetch in the traditional forage oat crop to improve its feeding value. An agronomic evaluation was undertaken by intersowing common vetch at 40 kg seed/ha with oats at 80-100 kg/ha in small plots, recording the yield and the chemical composition of the fresh forage in ten plots at harvest. The data were analysed as a completely random design, taking each farmer/plot as a treatment. A feed...
[Keeping of horses in circus and show businesses].
DTW. Deutsche tierarztliche Wochenschrift    April 20, 2002   Volume 109, Issue 3 126-129 
Pollmann U.The conditions under which horses are kept and the performance of acts in the circus ring may give rise to animal protection-relevant aspects for circus and show horses. A number of intolerable conditions under which horses are kept and procedures adopted for the work with circus and show horses are described. In addition, attention is drawn to monitoring methods capable of exposing the deplorable shortcomings of these businesses.
Cataract phacofragmentation in horses.
Veterinary ophthalmology    June 9, 2001   Volume 3, Issue 2-3 157-164 doi: 10.1046/j.1463-5224.2000.00139.x
Millichamp NJ, Dziezyc J.Cataract surgeries were carried out in fifty-one eyes of 36 horses over a 15-year period. Cataracts were removed using phacofragmentation and aspiration. Useful vision was restored after surgery in 30 horses. One year after surgery 16 of the 19 horses for which follow up information was available were still visual with several still being used as working horses. At 5-6 years after surgery three horses were still visual. The most frequent intraoperative complication was tearing of the posterior lens capsule. The most frequent postoperative problem was superficial corneal ulceration. Four eyes i...

Should equine athletes commence training during skeletal development?: changes in tendon matrix associated with development, ageing, function and exercise.
Equine veterinary journal. Supplement    February 5, 2000   Issue 30 201-209 doi: 10.1111/j.2042-3306.1999.tb05218.x
Smith RK, Birch H, Patterson-Kane J, Firth EC, Williams L, Cherdchutham W, van Weeren WR, Goodship AE.In human athletes, conditioning, training and competition are commenced before skeletal maturity. Yet in equine athletics, racing of young (age 2 years) horses remains contentious. Tendon injury persists as major causes of wastage in equine athletes. Minimising injury and associated welfare issues could involve a radical approach to the timing and implementation of conditioning and training. Tendons were examined from Thoroughbreds, Dutch Warmblood foals, working horses and also a group of wild horses to evaluate effects of age, function and exercise. Gross mechanical properties did not differ...
Alternative approaches to control of cyathostomes: an African perspective.
Veterinary parasitology    September 15, 1999   Volume 85, Issue 2-3 151-225 doi: 10.1016/s0304-4017(99)00095-3
Krecek RC, Guthrie AJ.Cyathostomes are common nematode parasites of horses, donkeys and mules in developing countries. These equids usually work on a daily basis and this includes transportation of goods, crops and people. Stress, associated with work, and limited nutrition often result in a loss of condition, and cyathostomid nematodes may, then, cause clinical disease. Because anthelmintics are not always accessible or affordable in many parts of Africa, or there may be anthelmintic resistance to current remedies, management practices are often used as an adjunct to chemotherapy. This paper discusses some current...
Performance and management of draught animals in agriculture in sub-Saharan Africa: a review.
Tropical animal health and production    January 9, 1999   Volume 30, Issue 5 309-324 doi: 10.1023/a:1005059308088
Pearson RA, Vall E.Use of animal power generally enables farmers in sub-Saharan Africa to increase agricultural production and improve the quality of life. Effective use of working animals depends on an understanding of the capabilities of the animals for work, their husbandry requirements and the factors which can influence their performance. These issues are reviewed in this paper in the context of the use of animal power in agriculture in sub-Saharan Africa. The type of animal used for work determines power available to the farmer. The performance of donkeys, horses and cattle have been compared in work tests...
[The components of the phenotypic dispersion of the basic typological traits and of work capacity in horses of the Ukrainian saddle breed].
TSitologiia i genetika    January 8, 1999   Volume 32, Issue 3 93-96 
Kotsiubenko AA.The indexes of standardized deviations by the measured characters (probits) are expedient to be used for distribution of horses according to classes M-, M0 and M+, under these conditions one can select individuals M0 for to rise their capacity for work and expressivity of the type of breed.
Effect of density and weight of load on the energy cost of carrying loads by donkeys and ponies.
Tropical animal health and production    August 28, 1998   Volume 30, Issue 1 67-78 doi: 10.1023/a:1005021729061
Pearson RA, Dijkman JT, Krecek RC, Wright P.Two experiments were designed to compare the energy used in carrying loads by donkeys and ponies. In the first experiment 3 donkeys and 3 ponies were compared on treadmills in the UK. Density of load (lead shot or straw) had no significant effect on the energy cost of carrying loads; however, the energy cost of carrying a load decreased significantly (p < 0.001) as the weight of the load increased (in donkeys 6.44, 4.35 and 3.03 J/kg load/m, in ponies 5.82, 3.75 and 3.68 J/kg load/m, for loads of 13, 20 and 27 kg/100 kg liveweight (M) respectively). Differences between species were not sign...
[Adaptation to hypoxia as a factor enhancing work capacity].
Vestnik Rossiiskoi akademii meditsinskikh nauk    January 1, 1997   Issue 5 46-50 
Kozlov SA.The results of applying N. N. Sirotinin's concept of the use of hypoxic adaptation to enhance working capacity are given. There is evidence for the efficiency of adaptation of trotters to two hypoxias: to hypoxic hypoxia (in the midmountains) and to exercise hypoxia (during interval training under the conditions of Moscow) for increasing their performance. These studies demonstrated that in the midmountains, the trotters had more infrequent respiration, increased respiratory and minute respiratory volumes which were more obvious by the end of a monthly mountain stay. The monthly training of tr...
Flexion test of the metacarpophalangeal and interphalangeal joints and flexion angle of the metacarpophalangeal joint in sound horses.
Equine veterinary journal    January 1, 1997   Volume 29, Issue 1 50-54 doi: 10.1111/j.2042-3306.1997.tb01636.x
Verschooten F, Verbeeck J.This paper describes the application of a measuring device 'Flextest' to control the effect of traction force and traction time during flexion tests of the distal limb joints of the forelimbs. The optimal force for a flexion test is 100 N, over 1 min. A higher force (150 N) was not harmful. A slightly positive flexion response (100 N/1 min) in a horse with no other clinical signs or radiographic abnormalities is not of clinical significance. Individual left and right flexion and extension angles are almost identical and do not depend on age. Stabled horses which have been rested or horses rest...
Effects of sex and age on the ossification of the collateral cartilages of the distal phalanx of the Finnhorse and the relationships between ossification and body size and type of horse.
Research in veterinary science    January 1, 1997   Volume 62, Issue 1 34-38 doi: 10.1016/s0034-5288(97)90177-6
Ruohoniemi M, Laukkanen H, Ojala M, Kangasniemi A, Tulamo RM.The ossification of the collateral cartilages of the distal phalanx was evaluated in dorsopalmar radiographs of the front feet of 202 Finnhorses (101 females and 101 males, aged six months to 20 years) with reference to the sex, age, body measurements and type of horse. Ossification was more common and more extensive in females than in males from about two years of age. In females, the lateral cartilages were significantly more ossified than the medial cartilages; in males, ossification was more symmetrical in the cartilages of each foot. The amount of ossification increased rapidly during the...
Integrative model for predicting thermal balance in exercising horses.
Equine veterinary journal. Supplement    July 1, 1996   Issue 22 7-15 doi: 10.1111/j.2042-3306.1996.tb05026.x
Mostert HJ, Lund RJ, Guthrie AJ, Cilliers PJ.A theoretical integrative model was developed to determine the heat balance of horses working in a given environment. This model included the following parameters: metabolic heat gain, solar heat gain, evaporative heat loss due to sweating, respiratory tract heat loss, radiation from the body and heat gain or loss due to convection and conduction. The model developed in this study includes an unique approach for estimating heat loss via evaporation of sweat from the animal's skin surface. Previous studies modelling evaporative heat dissipation were based on the volume of sweat loss. While it i...
Estimation of the liveweight and body condition of working donkeys in Morocco.
The Veterinary record    March 9, 1996   Volume 138, Issue 10 229-233 doi: 10.1136/vr.138.10.229
Pearson RA, Ouassat M.The age, sex, liveweight and body measurements (heart girth, umbilical girth, height, length from elbow to tuber ischii and circumference of the foreleg cannon bone) of 516 donkeys used to transport goods in Morocco were recorded. There were few donkeys over 12 years of age. For adult donkeys weighing from 74 to 252 kg, the best equation with only one variable for predicting liveweight was: liveweight (kg) = heart girth (cm)2.65/2188. The inclusion of two variables improved the prediction marginally, but the addition of further variables gave little further improvement. The best prediction equ...
