A comparison of fitness between horses with different exercise history AgEcon
Barker, Anna B.E.; Warren-Smith, A.K..
Anecdotal evidence suggests that a horse’s prior fitness level has an effect on the horse’s ability to return to that previous level of fitness. This trial aimed to test this assumption which would benefit horse trainers to create individual fitness programs for horses. Standardised exercise testing was used to compare the progress of two groups of horses during weeks three and seven of a 14-week training program. Group A had undergone a similar training program twelve months previously and Group B had not. Plasma lactate samples and heart rate monitoring were used to assess the levels of fitness of the horses. Analysis of variance showed that there was no significant difference in post-exercise plasma lactate concentration between the groups. The horses...

Teixeira-Neto,A.R.; Ferraz,G. C.; Moscardini,A. R. C.; Balsamão,G. M.; Souza,J. C. F.; Queiroz-Neto,A..
This study tried to monitor the alterations of muscle enzymes activity - creatinokinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferase (AST) - in a group of horses that participated of 70 and 100km distance rides in five competitions of an annual endurance championship under tropical climate. Pre ride levels (U/l) were 245.13±9.84 for CK, 496.61±14.76 for LDH, and 328.95±8.65 for AST. When compared to these levels, the results revealed a significant decrease in all enzymes activities in the first moment of the rides. Peak levels, significantly different, were reached, immediately after rides by CK (413.591±50.75); 24 hours post rides by LDH (628.61±33.30); and 48 hours after rides by AST (389.89±16.96). Monitoring of recovery period...

An update on equine laminitis Ciência Rural
Laskoski,Luciane Maria; Valadão,Carlos Augusto Araújo; Dittrich,Rosangela Locatelli; Deconto,Ivan; Faleiros,Rafael Resende.
ABSTRACT: Laminitis is a severe podal affection, which pathophysiology remains partially renowned. Ischemic, enzymatic, metabolic and inflammatory mechanisms are connected to the development of laminar lesions. However, few therapeutic measures are effective to prevent or control the severity of acute laminitis and its prodromal stage, which often determines serious complications such as rotation and/or sinking of the distal phalanx and even the loss of hoof. The purpose of this study is to compile the actual knowledge in respect to the pathophysiology and treatment of equine laminitis.

Biometrical alterations of Trypanosoma evansi isolate in laboratory rodents. Repositório Alice
DAVILA, A. M. R.; RAMIREZ, L.; SILVA, R. A. M. S..
Biometrical alterations in a horse Trypanosoma evansi isolate were observed when passaged in laboratory rodents. The major parasite transformation observed was the increase in the total length as a consequence of an increase in some parasite measurements. These transformations probably occurred as a consequence of a host change from horse to rodents. No kinetoplastic forms were observed.

Blood lactate threshold reflects glucose responses in horses submitted to incremental exercise test Arq. Bras. Med. Vet. Zootec.
Ferraz,G.C.; D’Angelis,F.H.F.; Teixeira-Neto,A.R.; Freitas,E.V.V.; Lacerda-Neto,J.C.; Queiroz-Neto,A..
Determinou-se, em eqüinos, o efeito do treinamento sobre as concentrações sangüíneas de lactato e plasmáticas de glicose durante exercício de intensidade progressiva em esteira rolante. Demonstrou-se que o treinamento aeróbico causou diminuição da concentração máxima de lactato e que o limiar de lactato corresponde ao ponto de inflexão da curva de glicose plasmática, confirmando esse parâmetro como indicador da capacidade aeróbica de cavalos.

Carbohydrate metabolism and metabolic disorders in horses R. Bras. Zootec.
Hoffman,Rhonda M..
Horses evolved consuming primarily fermentable forage carbohydrates, but forage diets have been traditionally supplemented with grain meals rich in starch and sugar in order to provide additional calories, protein and micronutrients. Starch and sugar are important for performance horses, but the consumption starch-rich meals may cause equine digestive and metabolic disorders. The critical capacity for preileal starch digestibility appears to be 0.35 to 0.4% but may be as little, depending on the source of starch. Small intestinal absorption of simple sugars is limited by the activity and expression of two classes of glucose carrier proteins, which are affected by chronic intake of hydrolyzable carbohydrate but may be sluggish to respond to abrupt changes...

Cardiovascular assessment in horses sedated with xylazine or amitraz Arq. Bras. Med. Vet. Zootec.
Linardi,R.L.; Canola,J.C.; Valadão,C.A.A..
Cardiovascular effects due to intravenous (IV) xylazine (1.0mg/kg) or amitraz (0.1 or 0.4mg/kg) were evaluated in horses. Left ventricular function indexes, heart rate (HR), and cardiac output (CO) were measured by echocardiography. Second degree atrioventricular (AV) block was detected by electrocardiography. Invasive arterial blood pressure (AP) was also evaluated. All parameters were measured immediately before and during 60 minutes after drug injection. HR, CO, and second degree AV block were different between xylazine and amitraz-0.4mg/kg groups. Xylazine induced initial hypertension 10 minutes after injection, and hypotension was observed 30 minutes after amitraz-0.4mg/kg administration. Except for the second degree AV block which occurred only at...

Cerebral equine hydatidosis in Southern Brazil Ciência Rural
Ruas,Jerônimo Lopes; Schild,Ana Lucia; Fernandes,Cristina Gevehr; Ferreira,João Luiz Montiel; Müller,Gertrud.
Equine cerebral hydatid disease is described in a 7-year-old, crossbred, female horse. Clinical signs were characterized by circling gait, pressing of head against fences or objects and motor incoordination. On gross examination of the brain the hemispheres were swollen, mainly the left one. On transversal sections, a 5cm X 7cm fluid-filled cyst was observed within the lateral ventricle of the left hemisphere. The cyst extended from the parietal to the occipital lobe, and compressed the third ventricle. There was also marked mid line deviation. Histologically, the brain lesion adjacent to the cyst, was characterized by a piogranulomatous process and vacuolization of neuropil. A diagnosis of equine hydatidosis caused by Echinococcus granulosus was made on...

Prioli,R.A.; Curi,R.A.; Chardulo,L.A.; Gomes,V.N.; Prioli,S.M.A.P.; Mota,M.D.S..
The objectives of this study were to standardize a PCR-RFLP genotyping method for the AY_731081:g.1900T>C SNP of the equine CD14 gene, and to characterize this SNP and two other polymorphisms (AY_005808: c.1530A>G of the TLR4 gene and AX_463789: g.133T>C of the Cε gene) in Mangalarga horses, in order to contribute to future studies investigating the association between DNA markers and traits related to immune system physiology in this breed. A total of 151 Mangalarga horses of both sexes and variable ages, representative of the population of São Paulo State, were used. PCR-RFLP was found to be adequate for genotyping of the AY_731081: g.1900T>C SNP of the equine CD14 gene. However, this polymorphism is probably not present in Mangalarga horses,...

Santos,Renato de Lima; Oliveira,Tatiane de Fátima Brandão de; Oliveira,Taismara Simas de; Galvão,João Felipe Brito; Paixão,Tatiane Alves da; Goloubeff,Barbara.
A 22 year-old horse developed cholelithiasis with marked atrophy of the right lateral hepatic lobe. The horse had a history of intermittent colic since three years of age, and one of the first episodes of colic was associated with icterus. The size of the right lateral hepatic lobe was extremely reduced. There was a large choledocholith in the common hepatic duct, and several hepatoliths and choleliths in the intra- and extra-hepatic billiary ducts. Microscopically, there was severe atrophy of the right lobe with diffuse proliferation of connective tissue and billiary ducts. The left lateral lobe had peri-portal fibrosis with proliferation of billiary ducts, and billiary stasis. Chemical analysis of the calculi detected amorphous and triple phosphate,...

Clinical use of laparoscopy in horses MV&Z
Silva, Luís Cláudio Lopes Correia da; Ferreira, Márcio Augusto; Baccarin, Raquel Yvonne Arantes; Fernandes, Wilson Roberto.
Although laparoscopic techniques have been known and used in horses since 1970, their clinical use has improved only during the last years. Laparoscopy is frequently indicated in cases of peritonitis, intestinal lesions, duodenojejunitis, adhesions, cryptorchidism, internal organ biopsy and diagnosis or abdominal abscesses and tumors. Adequate knowledge about the technique, laparoscopic anatomy and clinical applications wil1 allow laparoscopy to become a routine diagnostic method in equine medicine.

Comparative polypeptide profiles of whole cell lysate antigens of Trypanosoma evansi isolated from three different hosts of eastern India OAK
Laha, R; Sasmal, N.K; Bandyopadhyay, S.
Trypanosoma evansi from buffalo, cattle and horse isolates were purified by Diethylaminoethyl cellulose column chromatography. The purified trypanosomes from each sources were used separately for preparation of whole cell lysate antigens. A comparative study on polypeptide pattern of whole cell lysate antigens of these three isolates of T. evansi was studied. It showed a total of 11 dominant polypeptide bands with relative molecular weight ranging from 95 to 13 kDa, when resolved in 10% sodium dodecyl sulphate polyacrylamide gel electrophoresis and stained with Coomassie brilliant blue. Except some minor differences between the relative molecular weight of isolates in a particular region, the polypeptide profiles of these three isolates did not resolve any...

Comparison of behavioral and clinical effects of intravenous amitraz or romifidine administration in horses Arq. Bras. Med. Vet. Zootec.
Mendes,M.C.; Reis,R.G.; Valadão,C.A.A.; Marques,J.A..
Clinical and behavioral effects of intravenous injection of romifidine (60mcg/kg) or amitraz (0.4mg/kg) were compared in six horses, over 120 min. Romifidine caused head ptosis (HP), reduced respiratory rate (RR) and ileo-cecal sphincter activity (IC) until 120 minutes; produced posture changes (PC) until 90 minutes, upper eyelid drop (ED) and sedation (SD) until 60 minutes, intestinal motion (IM) reduction and lower lip drop (LD) until 45 minutes. Amitraz reduced heart rate (HR), RR, IM and IC, and promoted HP, ED, LD, penis drop (PD) and sedation with posture changes until 120min. At 90min amitraz produced HP and ED more intensively than romifidine. The LD was similar between 45 and 60 minutes. Romifidine produced intense sedation at 10min while amitraz...
