          Abstract

          O objetivo deste estudo é comparar e descrever medidas morfométricas e perfil energético de éguas da raça Crioula no terço final da gestação. Foram utilizadas vinte éguas gestantes, divididas em 2 grupos conforme o escore corporal (BCS); o GrN (n=10), grupo de éguas com BCS 5 ou moderado, e GrO (n=10), grupo de éguas obesas ou BCS 9, analisadas conforme o mês de gestação (8º, 9º, 10º e 11º). Foram realizadas coletas de sangue e avaliações morfométricas mensais do peso corporal (PC), perímetro torácico (PT), perímetro abdominal (PA), altura da crista do pescoço (AC), espessura de gordura subcutânea na base da cauda (EGBC) e espessura de gordura retroperitoneal (EGRP). Para avaliar o perfil energético, foram mensurados os níveis séricos de triglicerídeos (TAG), ácidos graxos não esterificados (NEFA), Leptina (LEP) e Adiponectina. Os resultados das mensurações analisadas demonstraram no GrN incremento (P<0,05) nas variáveis PC, PT, PA e NEFA do 8º para o 9º mês de gestação. Porém, na variável EGBC, o aumento (P<0,01) foi observado entre o 8º e o 11º mês avaliado. No GrO, o PA demonstrou incremento (P<0,01) entre o 8º e o 11º mês de gestação, e a LEP apresentou aumento (P<0,05) entre o 10º e o 11º mês. Quando os dois grupos foram comparados, as variáveis PC, PT, EGBC e EGRP apresentaram diferença (P<0,05) em todos os meses avaliados. Na análise de correlação, o BCS associou-se com o PC (r=0,691; P<0,0001), PT (r=0,705; P<0,0001), EGBC (r=0,701; P<0,0001), EGRP (r=0,627; P<0,0001), níveis séricos de LEP (r=0,426; P<0,0001) e Adiponectina (r=0,217; P<0,05). Dessa forma, pode-se afirmar que a gordura corporal aumentou progressivamente nas éguas do GrN, diferentemente do observado no GrO. Através dos métodos utilizados neste trabalho, torna-se possível a avaliação prática da morfometria das éguas da raça Crioula no terço final da gestação, possibilitando de forma objetiva a identificação de indivíduos obesos.

          The aim of this study was to compare and describe morphometric measurements and energy profile of the Crioula breed mares at the end of gestation. Twenty pregnant mares were used and separated into 2 groups according to body condition score (BCS). The GrN (n= 10) group of mares with BCS 5 or moderate and GrO (n = 10) group of obese mares or BCS 9 were analyzed according to the month of pregnancy (8th, 9th, 10th and 11th). Blood samples and monthly morphometric evaluation were performed for body weight (PC), heart girth (PT), waist circumference (PA), height of the crest of the neck (AC), thickness subcutaneous fat on the base of the tail (EGBC) and retroperitoneal (EGRP). To evaluate the energy profile serum levels of triglycerides (TAG), non-esterified fatty acids (NEFA), leptin (LEP) and adiponectin were measured. The results of the analyzed measurements showed an increase in GrN (P<0.05) in the PC, PT, PA and NEFA variables between the 8th and 9th month of pregnancy. Although there was an increase (P<0.01) between the 8th and 11th month of pregnancy in the EGBC variable, in GrO the PA was increased (P<0.01) between the 8th and 11th month of pregnancy and the LEP showed an increase (P<0.05) between the 10th and 11th month. When both groups were compared, the variables PC, PT, EGBC and EGRP showed differences (P<0.05) in all months evaluated. In the correlation the BCS was associated with PC (r=0.691, P<0.0001), PT (r=0.705, P<0.0001), EGBC (r=0.701, P<0.0001), EGRP (r=0.627, P<0.0001), serum leptin levels (r=0.426, P<0.0001) and adiponectin (r=0.217, P<0.05). Thus, it can be stated that the body fat increased progressively in mares GrN, different from that observed in GrO. Therefore, by the methods used in this study, the morphometry practical evaluation of the Crioula breed mares in the last third of gestation became possible, allowing an objective way to identify obese individuals.

          Adiponectin and leptin are related to fat mass in horses.

          Plasma concentrations of adiponectin and leptin were measured in 23 mature Standardbred mares (age: 10+/-3 years) and 12 weanling fillies (10 Quarter Horse/Belgian crossbreds and two Quarter Horses; aged: 4+/-3 months) to test the hypothesis that adipocytokines are proportional to adiposity in horses. Rump fat thickness was measured using B-mode ultrasound and percent body fat (% fat) calculated using a published formula for the estimation of fatness in horses. Plasma adiponectin and leptin were determined using radioimmunoassay. In the absence of purified equine adiponectin or leptin, results were expressed as human equivalents (HE) of immunoreactive (ir) adipocytokines. Plasma ir-leptin HE concentration was positively correlated (r=0.543; P<0.001) with percent body fat and (r=0.556; P<0.001) to fat mass in all horses. The plasma ir-leptin HE concentration was lower (P=0.03) in weanlings (1.90+/-0.34 ng/mL HE) than in mature mares (3.47+/-0.50 ng/mL HE). The ratio of ir-adiponectin HE to ir-leptin HE was negatively correlated (r=-0.621; P<0.001) to percent fat and (r=-631; P<0.001) to fat mass in all horses. The ratio of ir-adiponectin HE to ir-leptin HE was higher (P<0.001) in weanlings (3.04+/-0.51) than mature mares (1.03+/-0.13). These data suggest that leptin is proportional while adiponectin is inversely proportional to adiposity in horses.
