“…As expected, the horses tolerated the two days of fasting without notable clinical signs. Similar results were described in Caspian miniature horses (Seifi et al, 2002), Akhal Teke horses (Tóth et al, 2018), Thoroughbred horses (Freeman et al, 2021), and mules and donkeys (Gupta et al, 1999) during fasting for 2 to 10 days.…”

“…Although severe behavioral changes were not observed during this restriction, the animals became more lethargic (reduction of ambulation and interaction) compared to the control animals, similar to the results described for ponies (Brinkmann et al, 2013), donkeys and mules (Gupta et al, 1999), Akhal Teke horses (Tóth et al, 2018) and sheep (Naqvi & Rai, 1988). These behavioral changes can be associated with normal adaptive behavior to conserve energy (Gupta et al, 1999) and may also be interpreted as an indicator of reduced welfare (Tóth et al, 2018). To our knowledge, our study is the first to analyze the effects of food restriction on blood and clinical parameters in horses maintained before the study in pasture in the summer.…”

“…Other studies have found an increase in levels of serum triglycerides, aspartate aminotransferase and alanine aminotransferase and decrease of glucose concentrations (Seifi et al, 2002). The effect of food restriction in horses has been evaluated in many studies (Connysson et al, 2010;Dugdale et al, 2010;Tóth et al, 2018). However, to our knowledge there are no reports of the effects of controlled feed restriction on horses kept outdoors under natural conditions in a tropical country.…”

The objective of this study was to evaluate the effect of feed restriction on some physical and blood parameters in horses kept outdoors under natural conditions. Twenty horses were deprived of food for 48 h. They were closely monitored and examined, and blood samples were taken at the beginning (0) of the experiment and 6, 12, 18, 24, 30, 36, 42 and 48 hours afterward. During the experimental period, the control group (12 animals) had free access to water and hay, while the restricted group had free access to water only. Data were submitted to two-way analysis of variance with repeated measures, and statistical significance was P ≤ 0.05. The horses tolerated feed restriction without complications. Feed restriction had no effect on body mass and body condition score, heart rate, respiratory rate, capillary filling time and body temperature. However, feed restriction decreased the intensity of gastrointestinal sounds (P<0.05) compared to the control horses. Feed restriction did not cause any changes in erythrocyte variables and gamma glutamyl transferase, creatinine, total protein, and albumin concentrations. During fasting, there was a reduction in the leukocyte response (P<0.05). Feed restriction significantly raised the levels of blood urea nitrogen (24 to 48 hours), aspartate aminotransferase (36 to 48 hours) and total cholesterol (42 to 48 hours). During 48 hours of fasting, there was a continuous increase in triglyceride concentration. Feed restriction for 48 h had a marked effect on the intensity of gastrointestinal sounds and was responsible for important metabolic changes in the healthy horses of our sample.

“…Acute stress can affect insulin and glucose concentrations via activation of the adrenocortical axis and by catecholamine release. It is advisable to minimize stress from transportation, environmental and feeding management changes, pain from active laminitis, or excessive starvation before testing . Although the absence of feed intake might be expected to decrease insulin concentrations, fasting for as little as 6 hours can cause IR in horses and donkeys .…”

Equine metabolic syndrome (EMS) is a widely recognized collection of risk factors for endocrinopathic laminitis. The most important of these risk factors is insulin dysregulation (ID). Clinicians and horse owners must recognize the presence of these risk factors so that they can be targeted and controlled to reduce the risk of laminitis attacks. Diagnosis of EMS is based partly on the horse's history and clinical examination findings, and partly on laboratory testing. Several choices of test exist which examine different facets of ID and other related metabolic disturbances. EMS is controlled mainly by dietary strategies and exercise programs that aim to improve insulin regulation and decrease obesity where present. In some cases, pharmacologic aids might be useful. Management of an EMS case is a long‐term strategy requiring diligence and discipline by the horse's carer and support and guidance from their veterinarians.

“…Já na parte de bioquímica sérica são demonstrados valores de redução de triglicérides, colesterol, uréia e glicose (MATSUZAWA; SAKAZUME, 1994;KALE et al, 2009). Para equinos, não existe na literatura consultada informações detalhadas sobre as variações ocorridas nos exames hematológicos e de bioquímica sérica durante diferentes períodos de jejum e seus efeitos sistêmicos, embora informações como hiperbilirrubinemia e hipertrigliceridemia tenham sido relatadas (MCKENZIE III, 2011;LIMA, 2013;TOTH et al, 2017).…”

ARANTES, J. A. Avaliação da influência do jejum no perfil bioquímico sérico e na cicatrização de feridas cutâneas induzidas em equinos. 2018. 103p. Dissertação Paulo, Pirassununga, 2018 O jejum ou anorexia podem resultar em diversos distúrbios metabólicos prejudicais ao organismo. Este estudo objetivou avaliar e comparar os efeitos do jejum no perfil hematológico, de bioquímica sérica e na cicatrização de feridas cutâneas induzidas em equinos. Os animais foram distribuídos aleatoriamente em quatro grupos experimentais, sendo eles: DT12, representado por quatro equinos que permaneceram 12 horas em jejum e receberam dieta total na reintrodução alimentar; DC12, representado por quatro equinos que permaneceram 12 horas em jejum e receberam dieta convencional na reintrodução alimentar; DT72, representado por quatro equinos que permaneceram 72 horas em jejum e receberam dieta total na reintrodução alimentar; e DC72, representado por quatro equinos que permaneceram 72 horas em jejum e receberam dieta convencional na reintrodução alimentar. A dieta total e a dieta convencional possuíam a mesma composição bromatológica, porém, a dieta total era composta por um único produto triturado (volumoso e concentrado) e misturado, enquanto a dieta convencional era composta por volumoso e concentrado fornecidos separadamente. No dia de início do jejum, foi induzida ferida de pele no flanco de todos os animais experimentais. O experimento foi desenvolvido em duas etapas, sendo utilizados os mesmos animais, respeitando-se um intervalo de 15 dias e realizando-se a ferida cutânea no flanco contralateral. Foram realizadas análises laboratoriais comparadas de hemograma, bioquímica sérica e avaliação macro e microscópica da cicatrização das feridas de pele, assim como avaliação de alterações em peso, escore corporal, consumo hídrico, aceitação e tempo de consumo das dietas e consistência das fezes. Os animais dos gru≤os DT72 e DC72 apresentaram hipertrigliceridemia, hiperbilirrubinemia, redução de leucócitos, aumento dos valores de ureia, AST, colesterol e redução no peso em até 6% (p≤0,05). Após a inclusão da alimentação, foi observada elevação dos valores de lactato. Nos grupos DT12 e DC12 não foram observadas alterações hematológicas e de bioquímica sérica, assim como não houve influência do tipo de dieta. A cicatrização das feridas cutâneas não foi influenciada pelo jejum ou pelo tipo de dieta, embora observações macroscópicas sugiram melhor cicatrização nos animais que permaneceram 12 horas de jejum. Conclui-se que 12 horas de jejum não apresentam alterações hematológicas e de bioquímica sérica, enquanto 72 horas de jejum acarretam distúrbios metabólicos e perda de peso.Palavras-chave: privação alimentar, dieta total, hipertrigliceridemia, pós-operatório, lactato ABSTRACT ARANTES, J.A.

Effect of feed deprivation on selected parameters of lipid mobilisation and hepatic function in healthy Akhal Teke horses

Abstract: Healthy Akhal Teke horses did not develop a catabolic crisis following 4 days of feed restriction and hyperlipaemia did not occur. Total BIL and tBA did not increase, thus were not useful indicators of inappetence in this group of horses.
