Topic:Livestock

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.
Clinical assessment of selenium status of livestock.
Journal of animal science    December 1, 1992   Volume 70, Issue 12 3928-3933 doi: 10.2527/1992.70123928x
Stowe HD, Herdt TH.Assessment of the selenium status of livestock is an important aspect of production medicine, but variations in reported values between laboratories and between methods may be > 30%. Reliable interpretations require considerable experience with an assay and an extensive database from field and research case samples of a variety of species. The Michigan State University Animal Health Diagnostic Laboratory (MSU-ADHL) has offered Se analyses by acid-digestion and fluorometric detection since 1982. This laboratory expects serum Se values (nanograms per milliliter) of livestock to increase graduall...
Comparison of trace elements in milk of four species.
Journal of dairy science    November 1, 1992   Volume 75, Issue 11 3050-3055 doi: 10.3168/jds.S0022-0302(92)78068-0
Anderson RR.The objective of this study was to compare trace elements in milks of four species. Milk samples of 4 ml or more were obtained from guinea pigs, dairy cattle, horses, and humans. The milks were analyzed for the trace elements Al, B, Ba, Cu, Fe, Li, Mn, Mo, Si, Sr, Ti, and Zn by inductively coupled argon plasma spectroscopy. Zinc ranged from more than 4 ppm in guinea pig milk to less than 2 ppm in mare milk. Strontium was over 1 ppm in the milk of guinea pigs and less than .1 ppm for the human. Iron ranged from over .7 ppm for the guinea pig to less than .2 ppm for the cow. Copper was over .5 p...

Milk and water intakes of foals sucking grazing mares.
Equine veterinary journal    July 1, 1992   Volume 24, Issue 4 295-299 doi: 10.1111/j.2042-3306.1992.tb02839.x
Martin RG, McMeniman NP, Dowsett KF.Intakes of milk and milk nutrients were determined for 8 foals at 11-18 days of age and for 10 foals at 30-44 days and 60-74 days of age while sucking grazing mares. Water intakes (sources other than milk) of the foals were determined at 30-44 days and 60-74 days of age. Five of the 10 mares were fed a protein supplement (24% crude protein) in addition to grazing during the stud season. The protein supplement did not influence foal intakes of milk and milk nutrients, milk composition, weight gains of the mares or the growth rate of the foals. Foal milk intakes increased (P less than 0.05) from...
Venezuelan equine encephalomyelitis and African horse sickness. Current status and review.
Annals of the New York Academy of Sciences    June 16, 1992   Volume 653 217-227 doi: 10.1111/j.1749-6632.1992.tb19650.x
Walton TE, Holbrook FR, Bolivar-Raya R, Ferrer-Romero J, Ortega MD.The arthropod-borne virus (arbovirus) diseases of livestock have worldwide impact. The prevention of an introduction of an exotic disease and the control of one subsequent to an introduction will require the attention, cooperation, and support of the livestock industry, regulatory agencies, and researchers. The most effective protection of our livestock industries is to prevent the introduction of an exotic disease agent. This implies complete restriction of animal imports and exports. However, "zero risk" is an unacceptable option in today's world of internationally integrated and interdepend...
Dietary selenate versus selenite for cattle, sheep, and horses.
Journal of animal science    June 1, 1992   Volume 70, Issue 6 1965-1970 doi: 10.2527/1992.7061965x
Podoll KL, Bernard JB, Ullrey DE, DeBar SR, Ku PK, Magee WT.Food and Drug Administration regulations currently permit addition of .3 mg of Se per kilogram of diet for chickens, turkeys, ducks, swine, sheep, and cattle. However, field reports indicate that this level may not be adequate for ruminants in all situations. Because sodium selenite is the most common supplemental form and is known to be readily absorbed to particles or reduced to insoluble elemental Se or selenides in acid, anaerobic environments, studies were conducted with dairy cattle, sheep, and horses fed sodium selenate to determine whether Se from this source was more bioavailable than...
Effects of fescue toxicosis on reproduction in livestock.
Journal of animal science    May 11, 1992   Volume 70, Issue 5 1594-1603 doi: 10.2527/1992.7051594x
Porter JK, Thompson FN.Fescue toxicosis in livestock is due to ingestion of endophyte (Acremonium coenophialum) -infected tall fescue. Understanding mechanisms responsible for decreased calving and growth rates, delayed onset of puberty, and impaired function of corpora lutea in heifers at puberty consuming endophyte-infected fescue is an emerging field in reproductive toxicology. The condition decreases overall productivity through a reduction in reproductive efficiency, reduced weight gains, and lowered milk production. Reproduction in cattle may be further compromised by winter coat retention, increased susceptib...

Management of stallions on large breeding farms.
The Veterinary clinics of North America. Equine practice    April 1, 1992   Volume 8, Issue 1 219-235 doi: 10.1016/s0749-0739(17)30477-7
McCarthy PF, Umphenour N.Often, there is an adversarial relationship between senior management and livestock managers. It is important that the veterinarian responsible for breeding management and health care maintain open communications with senior managers. Although the veterinarian may recognize livestock-management deficiencies that need changing, he or she must remain flexible within the constraints provided on the breeding farm. Years may be required to solidify this give-and-take relationship, and opinions on the value of many management procedures will change. The underpinnings of a successful stallion manager...

The present status of BCG treatment in the veterinary practice.
In vivo (Athens, Greece)    November 1, 1991   Volume 5, Issue 6 605-608 
Klein WR, Rutten VP, Steerenberg PA, Ruitenberg EJ.Horses with sarcoids, cows with ocular squamous cell carcinoma and dogs with mammary tumors were treated with intralesional injection of Bacillus Calmette Guérin. This treatment appeared to be effective in most cases of equine sarcoids, in 50 - 60% of the cows with ocular squamous cell carcinoma and was not effective in dogs with mammary tumors.
Ultrasonic determination of fetal gender in horses and cattle under farm conditions.
Theriogenology    November 1, 1991   Volume 36, Issue 5 809-814 doi: 10.1016/0093-691x(91)90346-f
Curran S, Ginther OJ.Accuracy of transrectal ultrasonic diagnosis of fetal gender by identifying and locating the genital tubercle was assessed in 85 horses and 102 dairy heifers and cows. Examinations were made once (horses and cattle) under farm conditions (cattle) on approximately Days 50 to 100. Definite diagnosis was made by removal of fetuses (horses) or after calving or abortion (cattle). In both species and both parities, accuracy was 100% (109 109 totaled over both species) when the certainty level recorded at the time of examination was 95 or 99%. At the lower levels of certainty (65 to 80%, 85 to 90%), ...
Trypanosoma evansi infection in cattle, buffaloes and horses in Indonesia.
Veterinary parasitology    March 1, 1991   Volume 38, Issue 2-3 109-119 doi: 10.1016/0304-4017(91)90121-b
Payne RC, Sukanto IP, Djauhari D, Partoutomo S, Wilson AJ, Jones TW, Boid R, Luckins AG.Cattle, buffaloes and horses in several areas of Indonesia were examined for evidence of infection with Trypanosoma evansi by the microhaematocrit centrifugation technique (MHCT) and an enzyme-linked immunosorbent assay (ELISA) for detection of antibodies to T. evansi. Evidence of infection was found in animals at each sampling site although differences were seen in prevalence rates between sites. Prevalence rates in buffalo were usually higher than in cattle in the same area while in horses they were much lower than in cattle or buffalo. An age-dependent prevalence rate was seen in buffalo an...
Hazards in confinement housing–gases and dusts in confined animal houses for swine, poultry, horses and humans.
Veterinary and human toxicology    February 1, 1991   Volume 33, Issue 1 32-39 
Pickrell J.Indoor atmospheres in swine or poultry confinement buildings, horse stalls or human dwellings contain gases, dusts and endotoxin in concentrations significantly in excess of those in outdoor environments. Although concentrations of such constituents differ appreciably between species, many of such differences may be related to differences in indoor mass loading and ventilation, or to the homogeneity of such ventilation. The high protein content of these indoor dust particles suggest they are of animal origin. Their ability to form bacterial colonies and to form or bind endotoxin suggest that t...
Synthesis of heat stress proteins in lymphocytes from livestock.
Journal of animal science    September 1, 1990   Volume 68, Issue 9 2779-2783 doi: 10.2527/1990.6892779x
Guerriero V, Raynes DA.Cultured bovine, equine, ovine and chicken lymphocytes responded to heat stress by the increased synthesis of a specific set of proteins known as heat stress proteins (HSP). Proteins with molecular weights of 70 and 90 kDa were synthesized in all species. Additional proteins were found in bovine, ovine and chicken lymphocytes. A time course of induction showed an increased synthesis of some of these proteins with only 30 min of heat stress and of several proteins with 60 min of heat stress. A specific monoclonal antibody was used to identify HSP70 as one of the stress proteins in bovine lympho...

The toxic factor in white snakeroot: identity, analysis and prevention.
Veterinary and human toxicology    January 1, 1990   Volume 32 Suppl 81-88 
Beier RC, Norman JO.White snakeroot (Eupatorium rugosum Houtt) has been known to cause trembles in animals and milk sickness in humans since the American Revolution. It still continues to poison animals. Horses and goats are particularly sensitive to white snakeroot poisoning. Resurgence of livestock production on small farm units, and utilization of fresh raw milk may result in milk sickness; if the animals have white snakeroot exposure. The goat is the only animal with good toxicity threshold data. In other animals and humans the toxicity thresholds of white snakeroot are not known, and that until responsible t...
Comparative features of retroviral infections of livestock.
Comparative immunology, microbiology and infectious diseases    January 1, 1990   Volume 13, Issue 3 127-136 doi: 10.1016/0147-9571(90)90275-x
Evermann JF.Retroviral infections of livestock have become of increasing importance due to their usefulness as comparative models for human retroviral infections and their effects upon animal health and marketability of animals and animal products nationally and internationally. This paper presents a perspective on the retroviruses of economic concern in veterinary medicine with emphasis on the importance of understanding the modes of virus transmission and the species specificity of the viruses. The retroviruses reviewed include the oncovirus, bovine leukosis virus, and the lentiviruses, equine infectiou...
Accuracy of prediction of the liveweight of horses from body measurements.
The Veterinary record    November 25, 1989   Volume 125, Issue 22 549-553 doi: 10.1136/vr.125.22.549
Jones RS, Lawrence TL, Veevers A, Cleave N, Hall J.Fifty-three horses, all but two of them over two years of age and varying in type, sex and liveweight (230 to 707 kg) were weighed and seven different body measurements were recorded in duplicate by a single operator. The best overall prediction of liveweight using an equation with two variables was found to be: liveweight (kg) = (umbilical girth [cm])1.78 X (length of body from tuber ischii to elbow [cm]0.97/3011). This equation had an adjusted R2 value of 94.9 per cent and was derived from the pooled data, because differences of sex, type and weight did not significantly affect the relations...
Forms of employment and species caseload of veterinary practitioners in New Zealand.
New Zealand veterinary journal    September 1, 1989   Volume 37, Issue 3 112-116 doi: 10.1080/00480169.1989.35577
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...
Tremorgenic syndromes in livestock.
The Veterinary clinics of North America. Food animal practice    July 1, 1989   Volume 5, Issue 2 291-300 doi: 10.1016/s0749-0720(15)30977-4
Nicholson SS.Grasses that are essential components of livestock grazing programs sometimes are the source of tremorgenic toxicants to the animals consuming them. Morbidity can be high but mortality need not be if management closely observes the cattle daily and removes them at first sign of trouble. Specific treatment generally is not available nor needed. Survivors recover completely within a few days or weeks, except in chronic phalaris poisoning, where sheep and cattle may die after prolonged illness--or at least not make an economical recovery. Certain poisonous plants are responsible for tremorgenic s...
[Anthrax in Chad: a zoonosis that still exists today].
Medecine tropicale : revue du Corps de sante colonial    July 1, 1989   Volume 49, Issue 3 245-251 
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...
Comparative ventilation and gas exchange in the horse and the cow.
Research in veterinary science    May 1, 1989   Volume 46, Issue 3 331-336 
Gallivan GJ, McDonell WN, Forrest JB.Ventilation and gas exchange were studied in healthy, adult horses and cows, two large species with different lung structures and different breathing patterns. The oxygen uptake (VO2), carbon dioxide output (VCO2), respiratory rate (fR), minute ventilation (VE), alveolar ventilation (VA), alveolar oxygen pressure (PAO2), and VE/VO2 ratio were higher in the cows, while the tidal volume (VT) and physiological dead space (VD) were larger in the horses. The arterial blood gases, alveolar-arterial oxygen pressure difference (PAO2-PaO2) and VD/VT ratio did not differ between the two species. The hig...

Single-dose pharmacokinetics of detomidine in the horse and cow.
Journal of veterinary pharmacology and therapeutics    March 1, 1989   Volume 12, Issue 1 65-72 doi: 10.1111/j.1365-2885.1989.tb00643.x
Salonen JS, Vähä-Vahe T, Vainio O, Vakkuri O.The pharmacokinetics of detomidine, a novel analgesic sedative, was studied in the major target species after high (80 micrograms/kg) i.v. and i.m. doses. In addition, drug residues in some organs were determined. Concentrations were measured using a sensitive, detomidine-specific radio-immunoassay method. Rapid absorption following i.m. dosing occurred. Absorption half-lives were 0.15 h (horse) and 0.08 h (cattle). The mean peak concentration in the horse (51.3 ng/ml) was achieved in 0.5 h and in the cow (65.8 ng/ml) in 0.26 h. The areas under the concentration curve after i.m. dosing were 66...
[Effect of selection on heterozygosity of farm animals].
TSitologiia i genetika    January 1, 1989   Volume 23, Issue 1 36-39 
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.

Kairi virus identified from a febrile horse in Argentina.
The American journal of tropical medicine and hygiene    November 1, 1988   Volume 39, Issue 5 519-521 doi: 10.4269/ajtmh.1988.39.519
Calisher CH, Oro JG, Lord RD, Sabattini MS, Karabatsos N.A virus isolated from the blood of a febrile horse in Argentina was identified as a strain of Kairi virus. This is the fifth Bunyamwera serogroup virus isolated from livestock and wild animals in the Americas. Bunyamwera serogroup viruses have been isolated from febrile humans in the Americas and Africa.
Arboviruses recovered from sentinel livestock in northern Australia.
Veterinary microbiology    October 1, 1988   Volume 18, Issue 2 109-118 doi: 10.1016/0378-1135(88)90056-9
Gard GP, Shorthose JE, Weir RP, Walsh SJ, Melville LF.Over 700 arboviruses were recovered between 1981 and 1987 from the blood of sentinel livestock near Darwin. Twenty-three isolates were made from sheep, goats, swamp buffalo (Bubalus bubalis) and horses, and the remainder were from cattle. The isolates have been typed as 27 separate viruses belonging to the bluetongue, epizootic haemorrhagic disease, Palyam, Simbu, bovine ephemeral fever, Tibrogargan and alphavirus groups. Ten of these viruses have not been isolated elsewhere in Australia and four have been isolated only in Darwin. Considerable annual variations in virus activity and in the dur...
