Livestock and horses are integral components of agricultural systems, providing resources such as meat, milk, fiber, and labor. Horses, in particular, have unique roles in agriculture, sport, and recreation, distinguishing them from other livestock. This topic explores the management, breeding, nutrition, and health of horses and other livestock species. It encompasses studies on husbandry practices, welfare considerations, and the impact of these animals on the environment and economy. The page includes peer-reviewed research studies and scholarly articles that investigate various aspects of livestock and equine science, offering insights into their biological, ecological, and economic significance.
Broquist HP, Mason PS, Hagler WM, Harris TM.When infested with the fungus Rhizoctonia leguminicola, certain forages, e.g., red clover hay, can cause a "slobber syndrome" of varying severity when consumed by ruminants. The causative agent has been presumed to be slaframine [(1S,6S,8aS)-1-acetoxy-6-aminooctahydroindolizine], which is produced by R. leguminicola. In one serious outbreak of the slobber syndrome in horses, the red clover forage involved was carefully examined and found to contain R. leguminicola and slaframine. An identical hay sample is shown here by ion-exchange chromatographic and gas chromatographic-mass spectrometric an...

Gray SJ.Faecal samples from 110 horses, 115 pigs, 111 sheep and 123 cows were examined for the presence of Aeromonas hydrophila, which was also sought in the available drinking water. The overall faecal rate was 11.8%, but significantly more bovine than other samples were found to be positive. There was significant association between the isolation of A. hydrophila from all animal faeces and its presence in drinking water, but this was not found when individual animal groups were analysed separately. An enrichment technique increased the total number of isolates by 77.1%. Strains of differing origins ...
Bouillant AM, Becker SA.The successive steps of maturation of seven retroviruses from five species of farm animals and one retrovirus from a mouse were compared in cell cultures. The viruses included three type C oncoviruses, one spumavirus, and three lentiviruses. Although members of the 3 subfamilies shared some gross morphologic features such as budding on plasma membranes, core, and surface projections, differences were noted in the ultrastructural detail of these features. Type C oncoviruses did not show any structural differentiation in identifiable form in the cytoplasm as opposed to characteristic features ob...
Baba AI, Gaboreanu M, Rotaru O, Kwieczinsky R.Malignant melanomas in 5 horses, 1 calf, 1 cow and 2 pigs were described. The disease, in white or gray horses, was tegumentally located and generalized in the organs of the abdominal cavity. Microscopically, dendritic and fusiform pigment cells and multinucleated cells were identified. In the hypophysis there microcysts and in one case a hypophyseal adenoma were encountered. Electronmicroscopically, differentiated melanophores and melanophages were also found. The mature melanosomes were intensely black and the elementary granules concentrically and lamellarly arranged. In cattle, the general...
Weiser MG.Erythrocyte volume distribution curves (erythrograms) were determined on a total of 300 blood samples from healthy dogs, cats, horses, and cattle (dairy cows). An index of anisocytosis was determined for these animals. Erythrograms were highly reproducible, and the mean corpuscular volumes determined from erythrograms compared well with those determined from hemograms. Bovine and equine erythrocyte volumes were found to be stable after the blood was stored at 4 C for 24 hours. Under the same conditions, canine and feline erythrocytes increased slightly in volume. After incubation of blood dilu...
Oltner R, Edqvist LE.Progesterone concentrations in heparinized plasma harvested immediately after blood collection were compared with levels obtained after storage of the corresponding whole blood for 2 h, 4 h, 6 h, 1 day, 2 days and 5 days at room temperature and in a refrigerator. The blood was taken during the luteal phase from 4 dogs, 4 horses, 4 pigs and 8 cows. For 4 cows the storage time was extended to 9 and 20 days. No significant effect of whole blood storage time on plasma progesterone concentrations could be shown for dogs or pigs. For the horse a slight but significant decrease was demonstrated when ...
Okoh AE.Between 1944 and 1977, the distribution of confirmed cases of rabies in farm livestock in Nigeria were 15 in cattle, 8 in goats, 4 each in sheep, pigs and horses and two in donkeys respectively. The less-cared-for pastoralist sheep - dogs as well as stray dogs have so far been the sole propagating animal species of rabies to farm livestock although wild fauna have been suspected. The fact that cases are sporadic and lower incidence of livestock rabies is generally reported than the number that actually occurs makes the formulation of a definite control measures difficult. The need to educate n...
Molenda J.Using the indirect hemagglutination test, antibodies against Enterobacteriaceae common antigen (CA) were tested in the sera of 123 horses, 142 cows, 108 sheep, 142 mature pigs and 60 piglets (3-4 weeks of age). Anti CA antibody level and antibody titers for somatic antigens (phenol-water extracts) various serogroups of E. coli (0149, 0138, 0115, 078, 09) and S. typhimurium were compared. Ca antibodies in titer equal or higher than 1:15 were found to occur in 100% of the examined horses and cows, while in the sera of 92% sheep, 80% of mature pigs and 60% of piglets antibodies to the common Ente...
Gherardi PB, Lindsay DR.Groups of 50 ewes were injected with serum from pregnant mares on 5 occasions, 3 months apart, and ovulation rate was estimated at laparoscopy. In Exp. 1, new ewes were used at each time and 3 dose rates (identical to 400, 630 and 1000 i.u. PMSG) were studied. In Exp. 2, the same ewes were used throughout and only 1 dose was given (1000 i.u.). In both experiments the response in ovulation rate of ewes varied significantly throughout the year, with the lowest response in spring (September) and the highest in autumn (March). The ewes in Exp. 2 were as responsive at the end as at the beginning of...
Archer M.The pasture needs for horses as compared to those for farm livestock are reviewed. The differing preferences of various types of grasses and other plants, and the patterns of grazing seen on"horse-sick" pastures, are discussed. Suggestions for practical management include frequent collection and removal of droppings, the use of grazing by cattle, adequate rest from horses and the application of cattle manure. Methods for controlling weeds and renovating horse-sick paddocks are discussed and compared to ploughing up. Finally, the place of fertilisers is considered for use on pastures for horses...
Willeberg P, Ruppanner R, Behymer DE, Haghighi S, Kaneko JJ, Franti CE.The prevalence of agglutinating serum antibodies against Coxiella burnetii, the cause of Q fever in humans, was tested in a hospital population of companion animals and livestock in California during 1973--1975. A sample of stray dogs was also tested. Among the hospitalized animals 346 (48%) of 724 dogs, 7 (9%) of 80 cats, 9 (32%) of 28 cattle and 31 (26%) of 121 horses had antibodies against C. burnetii. Of 316 stray dogs 208 (66%) were seropositive. The overall prevalence of 53% among 1040 dogs tested was comparable to the 63% antibody prevalence found in an earlier survey among coyotes and ...
Gareau L.Over the past decade, the cattle industry has experienced practically a full circle. With the promising beef prices in the early 1970s, with the glut of grain and a generous assist from government incentive programs, the forage acreage and cattle population have increased at a record rate. By 1974, the tide began to turn - grain prices went up sharply and beef prices became sluggish - and by 1976 a major crisis faced the producers. The cattle industry which had been developing on a cheap grain economy was now obliged to rely more on forage for its survival. Unfortunately, the forage was not ex...
Keeler RF, Balls LD, Shupe JL, Crowe MW.Cows, ewes, and mares varied considerably in susceptibility to toxicoses from the oral administration of the piperidine alkaloid, coniine. Cows were most susceptible and ewes least. Only calves had teratogenic effects from maternal administration of coniine during gestation; lambs and foals were apparently resistant. Results suggest that the marked differences between cattle and sheep are probably not due to variation in gut absorption or rumen metabolism.
Sharma VD, Sethi MS, Yadav MP, Dube DC.Sero-prevalence of brucellosis in man and animals was studied during the years 1976 and 1977. Samples were collected from Hospitals/slaughter houses/livestock farms located in Delhi and different districts of Uttar Pradesh (U.P.). The sera samples tested were from 1685 men, 1607 goats, 438 sheep, 244 pigs, 361 cattle, 551 buffalos, 50 dogs, 318 equine and 43 free living animals. The percentage of seropositivity, excluding doubtful ones, was recorded as: man 0.89, goat 5.53, sheep 3.42, pigs 15.98, cattle 6.37 buffalo 4.9 and equine 12.89. Additionally an evidence of agglutinins was also detect...
Wilson RT.Equines have been largely ignored in modern scientific literature on domestic animals, probably because they are not providers of meat and milk. Their contribution to the economy in the Sudan, however, is considerable and they are the principal means of transport both as baggage and as riding animals. They also play an important role in the supply of fuel and the distribution of domestic water in the larger villages and towns. Information on population structure is provided and descriptions, with particular reference to withers height and weight, are given of two types of donkey and of the hor...
Grant RC, Basson PA, Kidd AB.A paralytic condition of farm stock in South West Africa, characterized by prominent neuronal and some mild extraneuronal pigmentation, is described. The distribution of the pigment, which was mainly located in the larger neurones of the brain and spinal cord, is given. Experimental evidence, obtained by feeding the plant, is presented that the condition is caused by Trachyandra laxa var. laxa. The histochemical features of the pigment proved to be compatible with a lipofuscin.
Yilmaz O, Wilson RT.Mules are known to have been used as carriage and riding animals in Mesopotamia and Anatolia as early as the beginning of the second millennium BC but may have been first bred in Anatolia in the Third Century BC. They have thus contributed to Turkey's cultural, social and economic heritage for more than 4,000 years and were an ancient component of its guild of domestic animals and overall biodiversity. Once bred country-wide most mules are now introduced "illegally" to the southeast and east from Iraq and Iran. Mules are now bred only in one small area in north-central Turkey close to the Blac...
Verrinder JM, Phillips CJC.With growing understanding of animals' capabilities, and public and organizational pressures to improve animal welfare, moral action by veterinarians and other relevant professionals to address animal issues is increasingly important. Little is known about how their action choices relate to their moral reasoning on animal ethics issues. A moral judgment measure, the VetDIT, with three animal and three non-animal scenarios, was used to investigate the action choices of 619 students in five animal- and two non-animal-related professional programs in one Australian university, and how these relat...
Ramadan MM, Dailey D.This is the first account of fatal toxicity in horses resulting from grazing on the pasture plant creeping indigo, , on the island of Oahu, in the Hawaiian Islands. A survey in the town of Waialua on the north shore of Oahu island indicated that creeping indigo is common and abundant on grazing lands during the rainy season and requires intensive chemical and physical control measures. Four pastures were surveyed where ranchers reported mortality of more than 17 horses since 2020. We document these incidents to alert state animal and livestock support officials, groups monitoring invasive spec...
Alves BG, Alves KA, Hyde KA, Aguiar FLN, Souza SS, Brandão FAS, Garcia EC, Pinto Y, Gastal MO, Figueiredo JR, Teixeira DIA, Gastal EL.Ovarian tissue transplantation (OTT) is a technique well established and successfully applied in humans using mainly orthotopic or heterotopic transplantation sites. In livestock, OTT is still in its infancy and, therefore, different aspects of the technique, including the efficiency of different heterotopic OTT sites as well as the potential effect of age (i.e., young vs. old mares) in the ovarian graft quality, need to be investigated. The present study investigated the efficacy of the intramuscular (IM) or the novel subvulvar mucosa (SV) heterotopic autotransplantation sites to maintain the...
Woodger K, Stone EA.This article seeks to examine the history of equine surgery at the Ontario Veterinary College (OVC) in the context of the changing horse economy during the first half of the 20th century. We argue that despite the transition to livestock medicine, public health and small animal practice, the horse, especially as a surgical topic, retained a (diminished) place at OVC due to the lucrative new recreational equine market, the deep links between horses and veterinary medicine, and the equine focus for nearly half a century of Dr. W.J.R. Fowler, the College's primary surgical instructor.

Boland CJ, Morris RS.A survey by means of a postal questionnaire was undertaken to investigate the patterns of work and the need for information of veterinary practitioners in New Zealand. Of the 670 eligible veterinarians, 399 practitioners (60 per cent) participated in the survey. Of these, 38 per cent were in large animal practice (less than 20 per cent of work devoted to cats and dogs) and 31 per cent were in small animal practice (more than 80 per cent of work with cats and dogs). The remaining 31 per cent were in mixed practice, with a workload intermediate between the other two groups. Across the entire sam...
Velle W.This presentation is limited to the three groups of steroid sex hormones which alone or in combination have been shown to be anabolic when used in farm animals. It seems essential for realistic evaluation of public health aspects of use of these hormones that the discussions include naturally occurring levels of the hormones. The following topics will be dealt with for each group of hormones: 1. Types and sources; 2. Production rates; 3. Plasma levels; 4. Tissue concentrations; 5. Metabolism and excretion. Gestagens. Progesterone and 20-dihydroprogesterones are mainly produced in ovaries and p...
Hall SJ.An objective and accountable method is needed for deducing the number of registered animals in a breed from registration data. By following the principle that individual breeders register sufficient young females to be certain of having enough replacements for their current breeding stock, the ratios were calculated of the number of adult females in a breed to the number of female registrations, in a given year. Number of breeds considered were 8 cattle, 16 sheep, 8 pigs, 1 goat and 2 equines, all in the United Kingdom or Ireland. This yielded multipliers (4.4 for cattle, 3.3 for sheep, 3.1 fo...

Kouba V.This analysis of global veterinary personnel was based on the available quantitative data reported by individual countries to international organisations. The analysis begins with a time series of globally reported numbers of veterinarians, starting in the year 1959 (140,391). In 2000 this number reached 691,379. Of this total, 27.77% of veterinarians were working as government officials, 15.38% were working in laboratories, universities and training institutions and 46.33% were working as private practitioners. The ratio of veterinarians to technicians was 1:0.63. The global average of resour...
Inácio CT, Magalhães AMT, Souza PO, Chalk PM, Urquiaga S.Variations in the relative isotopic abundance of C and N (δC and δN) were measured during the composting of different agricultural wastes using bench-scale bioreactors. Different mixtures of agricultural wastes (horse bedding manure + legume residues; dairy manure + jatropha mill cake; dairy manure + sugarcane residues; dairy manure alone) were used for aerobic-thermophilic composting. No significant differences were found between the δC values of the feedstock and the final compost, except for dairy manure + sugarcane residues (from initial ratio of -13.6 ± 0.2 ‰ t...
Skarda RT, Muir WW, Ibrahim AI.The CSF concentrations of mepivacaine in 10 Standardbred horses and of procaine in 10 Holstein cows given the drugs by thoracolumbar subarachnoid injection were determined. Mepivacaine hydrochloride was injected into the horses (502 +/- 60.5 kg) at an average dosage of 30 mg (1.5 ml of 20 mg/ml solution). Analgesia was produced 7.5 +/- 4.3 minutes after injection, extended between spinal cord segments T13 and L3 on both sides of the spinal column, and lasted 47 +/- 18.7 minutes at the T18 dermatome. Procaine hydrochloride was injected into cows (614 +/- 51.5 kg) at a dosage ranging between 75 ...
Vincze B, Gáspárdy A, Kovács L, Albert E, Kézér L, Baska F, Szenci O.Transabdominal ultrasonography has been shown to be a useful and reliable method for assessing fetal well-being in horses and cattle. To test the applicability of fetal aortic diameter measurement in cattle, 44 late-term pregnant cows and heifers were examined 21 to 0 days prior to calving. Mean fetal aortic diameter was 2.07 ± 0.14 cm and mean fetal heart rate (FHR) was 109 ± 17 bpm. Three dead calves were dissected and their aortic diameter was measured in a water bath. The mean birth weight (n = 44) was 39.9 ± 5.8 kg. There was a significant negative correlation between FHR and fetal aor...
Mumford EL, McCluskey BJ, Traub-Dargatz JL, Schmitt BJ, Salman MD.To determine potential risk factors for vesicular stomatitis (VS) in Colorado livestock in 1995 and evaluate VS virus (VSV) exposure of Colorado livestock in 1996. Methods: Retrospective case-control study of VS risk factors and seroprevalence evaluation. Methods: Premises included 52 that had VS-positive animals and 33 that did not have VS-positive animals during the 1995 epidemic, and 8 in the vicinity of premises that had VS-positive animals during the 1995 epidemic. Methods: Layout and management data for premises were collected during site visits in 1996. Signalment and management data we...
Rozhkov IuI, Okhapkin SK, Vorob'ev EG, Bezenko SP, Galimov IR.A stabilizing selection which is made in cattle according to phenotypic characters affects simultaneously a genetic character--the level of individual heterozygosity++. As a result animals with mean (modal) level of heterozygosity++ have the least probability of elimination. Similarly, the driving selection in pigs and horses leads to a change in both phenotypic characters and genetic character, the level of individual heterozygosity++. In this case the most heterozygous animals have the least probability of elimination.
Feugang JM, Ishak GM, Eggert MW, Arnold RD, Rivers OS, Willard ST, Ryan PL, Gastal EL.Despite the progress in assisted reproductive techniques, there is still a lack of rapid and minimally invasive in situ approaches for further enhancements of female fertility. Therefore, we synthesized clinically relevant liposome nanoparticles for ovarian intrafollicular injection to allow in vivo cellular imaging for future drug delivery, using the mare as an animal model. Ovarian follicles of living mares were injected in vivo with fluorescently labeled liposomes. Samples of the follicular wall (mural granulosa, theca interna, and theca externa), granulosa cells, and follicular fluid wer...
Kaplan RM, Denwood MJ, Nielsen MK, Thamsborg SM, Torgerson PR, Gilleard JS, Dobson RJ, Vercruysse J, Levecke B.The faecal egg count reduction test (FECRT) remains the method of choice for establishing the efficacy of anthelmintic compounds in the field, including the diagnosis of anthelmintic resistance. We present a guideline for improving the standardization and performance of the FECRT that has four sections. In the first section, we address the major issues relevant to experimental design, choice of faecal egg count (FEC) method, statistical analysis, and interpretation of the FECRT results. In the second section, we make a series of general recommendations that are applicable across all animals ad...
Goranov Kh.The alkaline phosphatase enzyme, isolated by Morton's method from leukocytes of sheep, goats, and pigs gave after agarose elctrophoresis two isoenzyme fractions moving to the positive pole at the sites of the alpha 1- and alpha 2-globulins of the blood serum. In bovine leukocytes, besides these two fractions there was a third one that moved more slowly in the zone of the beta-globulins. In horses the alkaline phosphatase of leukocytes produced a wide band within the zones of the beta-globulins and the albumins. It was established that the proportion between the individual isoenzyme fractions o...
Littlewood KE, Beausoleil NJ, Stafford KJ, Stephens C, Collins T, Fawcett A, Hazel S, Lloyd JKF, Mallia C, Richards L, Wedler NK, Zito S.This descriptive study explored how end-of-life management was taught to students in all eight Australasian veterinary schools. A questionnaire-style interview guide was used by a representative at each university to conduct structured interviews with educators in a snowball sampling approach. Four categories of animals were addressed: livestock, equine, companion and avian/wildlife. This article focuses on the first part of the questionnaire: teaching the technical aspects of euthanasia. Euthanasia techniques were taught at more universities in clinical years than preclinical years. Clinical ...
Broder CC, Xu K, Nikolov DB, Zhu Z, Dimitrov DS, Middleton D, Pallister J, Geisbert TW, Bossart KN, Wang LF.Hendra virus and Nipah virus are bat-borne paramyxoviruses that are the prototypic members of the genus Henipavirus. The henipaviruses emerged in the 1990s, spilling over from their natural bat hosts and causing serious disease outbreaks in humans and livestock. Hendra virus emerged in Australia and since 1994 there have been 7 human infections with 4 case fatalities. Nipah virus first appeared in Malaysia and subsequent outbreaks have occurred in Bangladesh and India. In total, there have been an estimated 582 human cases of Nipah virus and of these, 54% were fatal. Their broad species tropis...
Easton S, Pinchbeck GL, Bartley DJ, Hotchkiss E, Hodgkinson JE, Matthews JB.The aim of this study was to determine practices, attitudes and experiences of UK prescribers of anthelmintics for horses and livestock. A questionnaire was sent by direct email to groups licenced to prescribe these medicines. These were veterinarians, Suitably Qualified Persons (SQPs, registered with the Animal Medicines Training Regulatory Authority) and veterinary pharmacists. The survey was also advertised through social media. It comprised questions relating to demographics, training experiences, current prescribing practices, as well as personal opinions on anthelmintic selection, diagno...
Mello GW, Riet-Correa F, Batista MC, Carvalho CJ, Dias AC, Franklin FL, Silva SM, Dias A.Farmers in the State of Piauí in northeastern Brazil reported nervous signs in ruminants and donkeys after ingestion of Brunfelsia uniflora at the start of the rainy season when the plant is flowering. Leaves of the plant, collected at the start or at the end of the rainy season, were administered in single doses of 5-20 g/kg body weight to 8 sheep and 3 donkeys. Two sheep and 1 donkey that ingested 10 g/kg of the plant in November at the start of the rainy season, when the plant was flowering, developed severe convulsions and diarrhea. One sheep was euthanized and autopsied, and no significa...
Ahuir-Baraja AE, Cibot F, Llobat L, Garijo MM.More than 50 years after anthelmintic resistance was first identified, its prevalence and impact on the animal production industry continues to increase across the world. The term "anthelmintic resistance" (AR) can be briefly defined as the reduction in efficacy of a certain dose of anthelmintic drugs (AH) in eliminating the presence of a parasite population that was previously susceptible. The main aim of this study is to examine anthelmintic resistance in domestic herbivores. There are numerous factors playing a role in the development of AR, but the most important is livestock management. T...
Sharma M, Nunez-Garcia J, Kearns AM, Doumith M, Butaye PR, Argudín MA, Lahuerta-Marin A, Pichon B, AbuOun M, Rogers J, Ellis RJ, Teale C, Anjum MF.In recent years, there has been an increase in the number of livestock-associated methicillin resistant Staphylococcus aureus (LA-MRSA) clonal complex (CC) 398 recovered from S. aureus isolated animals in the UK. To determine possible origins of 12 LA-MRSA CC398 isolates collected after screening more than a thousand S. aureus animal isolates from the UK between 2013 and 2015, whole genome sequences (WGS) of CC398 European, including UK, and non-European isolates from diverse animal hosts were compared. Phylogenetic reconstruction applied to WGS data to assess genetic relatedness of all 89 iso...
Aldayarov N, Tulobaev A, Salykov R, Jumabekova J, Kydyralieva B, Omurzakova N, Kurmanbekova G, Imanberdieva N, Usubaliev B, Borkoev B, Salieva K....In their centuries-old nomadic life, since their livestock was the backbone of their lives, the Kyrgyz people used a variety of wild medicinal plants for ethnoveterinary practices. However, the plants used for the treatment of livestock ailments never have been recorded, except rarely in local publications. In this study, we present the HSHR (homemade single species herbal remedy reports), their methods of preparation and application, and the livestock ailments for which these remedies were used. Objective: The collect data from the five different high-altitude valleys of the Kyrgyz Republic o...
Lamarque D, Haessler C, Champion R, Granga D, Bendina , Steinmetz P, Guelina A, Maurice Y.An epidemic of human and animal anthrax raged in Chad mainly in the Department of Chari Baguirmi from September to December 1988, infesting more than 50% of donkeys and horses. 716 human cases have been reported, with 88 deaths. Thanks to a geographical distribution of animal and human prevalence, one sees immediately the interdependency between sanitary state of live-stock and public health. An unusual means of transmission from donkey to donkey by insects as the vector is suggested to explain the intensity of animal epidemics. Two strains of B. anthracis were isolated and described. Systemat...
