“…Biomarkers of energy metabolism are important indicators of the state of nutrition and health of animals. The total CHOL (1.55 -2.60 mmol/L) and TRIG (0.68 -1.02 mmol/L) in donkeys are well described in the literature (Lee et al 1995, Mori et al 2003, Laus et al 2015, Barbosa et al 2016, different from NEFA. Both TRIG and NEFA are related to management system and food availability, different from total CHOL, so they should be used to evaluate the nutritional status of animals under different conditions.…”

“…Also it was observed that NEFA was significantly different between males (0.26 mmol/L) and females (0.11 mmol/L) (Chiofalo et al 2012, Simenew et al 2011, which it was also observed in present experiment, but inversely. Furthermore, Barbosa et al (2016), demonstrated that, when adult male and female donkeys are better fed, NEFA concentration decreases but TRIG did not change. Therefore, NEFA determination, associated with TRIG, may be a good indicator of donkeys' nutritional status and should always be used to evaluate the general state of these animals, even though it is not a method regularly used in practice.…”

Summary:In order to test the hypothesis that donkeys, housed in different management systems, present minimal variations in the concentration of various blood values, an experiment was carried out to evaluate blood values in Northeastern donkeys at maintenance, of both sexes, in different management systems. Sixty-two Northeastern donkeys were used, of both sexes, adults, healthy and housed in three management systems: Limoeiro (LIM), Natal (NAT) and Mirandiba/Salgueiro (MS), three different regions in the Northeast of Brazil. Body condition score, red blood cell count, haemoglobin, hematocrit, MCV, MCHC, leukocytes, lymphocyte, other white cells, RDW-CV, RDW-SD, platelets, MPV, total plasma protein, albumin, urea, creatinine, uric acid, glutamine, glutamate, triglycerides, total cholesterol, nonesterified fatty acids, AST, ALT, AP, CK, GGT, Ca, P, Cl, Fe, Na, K and Se were evaluated. Results were submitted to ANOVA with two factors (sex and rearing site) and to Tukey test, considering p<0.05. Results showed no difference in body score (p>0.05) and, in blood biomarkers, it was observed that RDW-CV and MPV were higher in females (p<0.05). In G-MS, red blood cells, Hb, HT and lymphocytes were lower than in G-LIM and G-NAT (p<0.05). In G-LIM, MCV and RDW-SD were lower (p<0.05). In relation to metabolic biomarkers, high concentrations of UA, TRIG, TC, NEFA, Ca and P (p<0.05) were observed in females. Higher concentrations of UA, TRIG, TC, P and Cl were detected in G-LIM (p<0.05), and G-NAT had the highest values for URE, GLU and CK (p<0.05). Results indicated that, even when kept under different management systems, donkeys may present some haematological and blood chemistry values with similar concentrations, and the few differences found may not present clinical significance for the evaluation of these animals. It was concluded that donkeys may present significant variations in different blood and metabolic parameters, when they are of different sexes and/or housed in different management systems. The red series, electrolytes and trace elements were not very sensitive to identify variations related to gender and/or rearing site groups. However, the count of lymphocytes, the combination of MVC with RDWs, CK, as well as concentrations of NEFA and triglycerides, can be used to better understand the adaptations of different management conditions or breeding systems, since they can be modified by the evaluated conditions, contributing to a better understanding of the state of health or disease of the animals of that species.

“…O pico da glicose também ocorreu, entre 120 e 180 minutos após a suplementação, de forma semelhante ao de outros trabalhos (Ralston e Baile, 1982;Healy et al, 1996;Witham e Stull, 1998 Barbosa et al (2016).…”

Efeito da suplementação com concentrados ricos em óleo sobre biomarcadores metabólicos para cavalos [Effects of supplementation with concentrates rich in oil over metabolic biomarkers in horses]"Artigo Científico/Scientific Article" Palavras-Chave: glicose; triglicérides; ureia, nutrição, equino. AbstractThe performance of athletic horses had been improved with the elevation of the fat percentagem (EE) in concentrates. The objetive of this research was evaluate the supplementation with concentrate with different levels of EE over metabolic biomarkers in athletic horses, using a latin square with five horses and 5 treatments (6,5% EE (T6,5%), 8% EE (T8,0%), 12% EE (T12,0%), 14% EE (T14,0%) e 20% EE (T20,0%)). Animais received their isocaloric supplementation during 15 days and at 16th day, we did blood collection in these period: overnight fastening and after 0.5, 1.0, 2.0, 3.0, 4.0, 5.0 e 6.o hours after they were fed. Blood was used to determine: hematocrit, glucose, total plasma protein, urea, creatinine, triglycerides, and total cholesterol. Results were anylaszed by ANOVA, with two factores and repeated measurements, and Tukey test, both with P<0.05%. Results showed variation in [Glucose] during blood collection phases (P<0.05), but without differences between treatments and the interaction treatment and phases (P>0.05). Also, there was no difference at the [glucose] peak between treatment and area under the curve (P>0.05). All other biomarkers did not change (P>0.05). In conclusion, isoenergetic supplementation with concentrates with different levels of fat did not produce changes in analyzed biomarkers, showing that variation in EE, between 6,5 and 20.0%, may be used for equine athletes similarly.

O uso em larga escala dos grãosde cereais processados para equinos tem sido associado à obesidade, síndrome metabólica e às disfunções na microbiota intestinal nessa espécie. Esses trabalhos objetivaram avaliar o teste oral com glicose de milho, com e sem sódio, sobre as concentrações plasmáticas de glicose, insulina e proteínas plasmáticas em cavalos sadios. A hipótese a ser testada é de que a adição de sódio à glicose de milho irá produzir diferentes curvas de glicose e de insulina quando os equinos em jejum, quando comparado com similar produto sem sódio. Foram utilizados seis equinos, distribuídos em um fatorial com três tratamentos (6x3). Os tratamentos foram: 400cal de glicose de milho com sódio (T-GNa400), 200cal de glicose de milho com sódio (T-GNa200), e 400cal de glicose de milho sem sódio (T-G400). Amostras de sangue foram colhidas com os animais nas seguintes fases: pré-teste (jejum) e 0,5, 1,0, 1,5, 2,0, 3,0 e 4,0 horas após a ingestão do tratamento. O plasma obtido foi utilizado para determinação da glicose ([GLIC]), insulina ([INSU]) e proteínas plasmáticas totais ([PPT]). Os resultados foram submetidos ao ANOVA com dois fatores (três tratamentos e sete fases) e ao teste deTukey, pelo programa SigmaPlot 13.0, com P estabelecido em 5%. Os resultados indicaram que [GLIC] difere tanto entre os tratamentos como entre as fases (P < 0,001), e que há interação significativa entre os tratamentos e as fases (P = 0,044). A [GLIC] foi mais elevada no T-GNa400 (~113,8 mg/dL), seguido pelo T-G400 (~106,4 mg/dL) e mais baixa no T-GNa200 (98,5 mg/ dL) (P < 0,001). Também a [INSU]apresentou diferenças entre os tratamentos e entre as fases (P < 0,001), e com interação significativa entre os tratamentos e as fases (P = 0.037). A maior [INSU] foi observada no T-GNa400 (~18,6 µIU/mL), seguido pelo T-G400 (~13,1 µIU/mL) e pelo T-GNa200 (~9,3 µIU/mL) (P < 0,001). Não ocorreram diferenças entre os tratamentos e entre as fases na [PPT]. Conclui-se que a glicose de milho, com sódio, durante o teste oral com ingestão produz curvas sanguíneas de glicose e insulina quando comparado com produto sem sódio, quando os equinos estão em jejum, sendo mais elevadas no T-GNa400.
