“…Given this stability, correlations between the different weight measurements and fat thickness during this period were expected. In addition, the correlations between measures of fat and metabolic weight corroborate the results of Marchiori et al [7], who demonstrate a difference between the values of fat increase in mares at the end of gestation when compared to other months. This is because the energy reserves for breastfeeding are acquired at this time of pregnancy, being an important tool to assess the differentiation of obese and healthy animals.…”

“…It was to be expected that the fact that triglyceride is one of the components of adipose tissue correlated with fat measurements. Marchiori et al [7] evaluating nonobese pregnant mares noted that the average fat thickness in the rump and retroperitoneal was 1.22 mm and 1.919 mm, respectively, and differed from the pregnant obese mares that dissipated an average of 1.13 mm, 2, 0.8 mm. The maximum value of our animals reached up to 0.889 mm of retroperitoneal fat and 1095 of fat on the rump.…”

Background: Mares are very different from other species during pregnancy, and studies on the physiological changes of this period are important. During late pregnancy, the distribution of weight and body fat are often used as indicators of adequate nutrition. This is a physiological period that results in an increase in metabolic demand. There is a tendency for the Criollo breed to have a higher body condition score that becomes more evident during pregnancy, a period when mares tend to gain more weight. The current study monitored serum cholesterol and triglyceride levels in pregnant mares during late gestation to determine a possible correlation with the distribution of fat or body weight.Materials, Methods & Results: Four body parameters of thirty-four Criollo-type mares in late gestation were evaluated: body weight measured with a weight scale, body weight using a commercial weight tape, total body fat and fat thickness and the serum levels of total cholesterol and triglycerides. The fat thickness was measured in an ultrasound device and the prediction of total body fat was calculated using an equation. According to the days prior foaling, biometric monitoring and blood collection were carried out in five periods: F-90 (± 90 days prior to foaling) n = 33; F-60 (± 60 days prior to foaling) n = 33; F-30 (± 30 days prior to foaling) n = 31; F-15 (± 15 days prior to foaling) n = 29 and Foaling (at day of foaling) n = 14. Mares were monitored daily and accompanied foaling was also performed, ensuring collection at the right time. Comparisons of means were performed between variables in addition to the Pearson correlation test. Statistical significance was established at P < 0.05. There was no difference in relation to the period in body composition measurements (P > 0.05). A strong positive correlation was observed between the average weights (P < 0.001). The fat thickness showed a correlation between the weights (P < 0.01). There was no correlation with body composition (P > 0.068). There was a strong positive correlation between weights (P < 0.001). In addition, differences in total cholesterol levels (P = 0.0016) were observed, with higher levels found in the Foaling period. The same was not observed for triglyceride levels (P = 0.443). There was no correlation between blood variables in this period (P > 0.191). There was also no correlation with the body composition (P > 0.068).Discussion: The absence of difference between the periods in relation to the weight measures and the correlations existing in these measures is related to the period in which they were collected, since the maximum relative weight of the foal is reached in ten months, causing the mare's weight stability. Interestingly, an unexplained increase in total cholesterol levels was found on the day of foaling. As the same change in triglycerides was not observed and there was no change in the diet or feeding behavior of the mares, the effects of the diet can be excluded in this case, which requires further studies to explain this result. Our hypothesis is that this increase is linked to hormones that tend to change in this pre-delivery period and that have their metabolism strongly linked to cholesterol levels. Levels of body fat and mare weight can therefore be correlated in the late gestation, allowing for their use as indicators of adequate nutritional and energy reserves.

“…Athlete horses generally present an ideal body condition score, while animals intended to morphology competitions usually have a higher BCS. Therefore, some authors assumed that Criollo breed is potentially predisposed to develop metabolic disturbances considering the genetic basis of the breed and the tendency towards obesity [13,15].…”

Background: The abdominal lipomas are benign tumors of hyperplastic growth that originate from mesenteric adipose tissue, most commonly in the small intestine. Pedunculated lipoma strangulation occurs when the pedicle wraps around an intestinal loop and its mesentery, obstructing the intestinal lumen and blood supply of the affected segment. The aim of the present study is to report a case of a Criollo mare presenting a strangulating obstruction of the jejunum and ileum by a pedunculated lipoma, focusing the discussion in the causes and epidemiology of this alteration.Case: A 24-year-old Criollo mare with a body condition score 8 out of 9 was referred to a Veterinary Clinical Hospital of the Federal University of Pelotas (HCV-UFPel) presenting acute abdominal pain. At the hospital, the mare was presenting mild signs of abdominal discomfort. At the initial clinical exam, the mare had an increased heart and respiratory rates, normal body temperature, hyperemic mucous membranes, capillary refil time of 3 s and absent gut sounds in all four quadrants during auscultation. Mild dehydration was present, increased fibrinogen and serum lactate. Rectal palpation revealed distention of the small intestine by gas, during abdominal ultrassonography the small intestinal wall thickness was found increased. Peritoneal lactate was 11 mmol/L and protein was 6 mg/dL. Due to the clinical findings during the exam, an exploratory celiotomy was performed. Necrosis of the final third of jejunum and the entire extension of ileum was found. Examining the compromised intestinal portion, it was observed a linear structure strangulating two segments of the small intestine. Taking into account the extensive area of irreversible necrosis and the advanced age of the patient, euthanasia was performed. The mare was then referred for necropsy and findings confirmed the strangulation of the final portion of the jejunum and all the extension of the ileum caused by a mesenteric pedunculated lipoma.Discussion: Increased mesenteric fat can predispose horses to the development of mesenteric lipomas. Although there is no scientific evidence of the association of mesenteric lipoma and obesity, it has been observed that pedunculated lipomas are more common in horses with metabolic alterations, for example, Criollo breed, that is potentially predisposed to develop metabolic disturbances. Elderly horses are at the highest risk of colic by mesenteric lipoma, as well as geldings, however, others authors describe that females are more commonly affected. Horses considered of short stature are more predisposed when compared to jumping or race horses. Pedunculated lipoma occurs in 18% of all cases of treated colic and is found more frequently in the small intestine when compared to the smaller colon. In most cases, surgery is indicated and resection of the pedicle and the affected segment may be necessary, however, in this case, the extensive area of intestinal necrosis and the impossibility of externalization of the affected segment lead the decision to proceed with euthanasia. In conclusion, the mare of the present study had an advanced age and a high body condition score, which the authors’ believe were two predisposing factors that increased the risk of it developing a mesenteric lipoma. Considering that, further epidemiologic studies should be conducted to better understand this relation.

“…Porém, no presente estudo, as éguas adultas gestantes (entre quatro e onze anos de idade) não foram suplementadas com concentrado, diferente do estudo de Heyden et al (2012), onde foram mantidas em sistema extensivo a campo. Contudo, estas éguas, mesmo em sistema a campo e sem suplementação apresentam média de escore de condição corporal 8, média de peso 557,29 +13,66 kg, gordura da base da cauda de 30,54 +3,17 mm e ECC > 8, compatíveis com a obesidade para éguas da raça Crioula, segundo Paz et al (2013) e Marchiori et al (2015). Gomes e Reis (1997), observaram uma concentração de produção de forragem relativa para o azevém de 56% no período da primavera, 30% no inverno e 14% no outono.…”

A busca intensiva por um manejo nutricional eficaz fez com que animais de diferentes categorias apresentassem sinais de sobrepeso. A obesidade é citada em diferentes raças como a causa de inúmeros problemas ortopédicos como laminite, osteocondrite dissecante e osteoartrite juvenil. O objetivo deste trabalho é avaliar por meio da avaliação radiográfica, a presença de alterações nas articulações do tarso de animais nascidos e criados em manejo extensivo em um criatório da raça Crioula, e que se mantinham em sobrepeso durante o ano todo. Foi realizado um estudo retrospectivo de coorte em condições de campo de fêmeas com sobrepeso e/ou obesidade desde o nascimento, até a idade adulta. Foram avaliadas 37 fêmeas equinas da raça Crioula, nascidas e criadas nesta mesma propriedade. Foi realizada a pesagem com fita e mensuração da gordura da base da cauda com a utilização de aparelho de ultrassonografia. As projeções radiográficas foram confeccionadas na região do tarso em ambos membros pélvicos. As éguas apresentaram média de escore de condição corporal 8, média de peso 557,29 +13,66 kg, gordura da base da cauda de 30,54 +3,17 mm. Cerca de 62,16% dos equinos apresentaram achados radiológicos, com alterações de diminuição de espaço articular, proliferações ósseas e osteófitos classificadas em grau 2, 3 e 4. Nos animais de um ano de idade (12 meses), foi observado 70% de alterações articulares nos ossos do tarso. Tanto a obesidade nas éguas em reprodução, quanto o sobrepeso nos animais em desenvolvimento, podem ser fatores etiológicos importantes para o desenvolvimento desta doença na raça Crioula.
