“…Urea and GGT have lower limits than those described by Hodgson et al (2014). Souza et al (2016) found wider reference ranges for AST, CK, urea, and creatinine in Campeiro horses than those observed in the Brazilian sport horses of this work. This difference can be explained by the homogeneity in management of the horses used in this study, which have the same diet, housing, and training protocol.…”

-This study aimed to provide baseline data for the serum biochemical parameters of Brazilian sport horses undergoing physical training for eventing to be used as a practical guide. A total of 139 blood samples were collected by vacuum venipuncture of the jugular vein from healthy horses in training. Tubes without anticoagulant were used for biochemical analysis. Means and standard deviations were determined for aspartate aminotransferase (AST) (306.27±84.66 U/L), creatine kinase (CK) (181.06±80.38 U/L), urea (29.51±5.82 mg/dL), creatinine (1.44±0.20 mg/dL), gamma glutamyl transferase (GGT) (14.58±6.55 U/L), calcium (13.22±0.59 mg/dL), and albumin (2.86±0.16 g/dL). The specific reference ranges were: AST, 197-454 U/L; CK, 116-290 U/L; urea, 22-42 mg/dL; creatinine, 1.2-1.8 mg/dL; GGT, 9-26 U/L; calcium, 12.2-14.2 mg/dL; and albumin, 2.6-3.1 g/dL. Beneficial effects of the training program on the horses were observed and these effects did not lead to any changes in the biochemical parameters studied. The environment may influence the serum biochemical parameters, particularly AST and CK, of Brazilian sport horses.

“…Blood values are affected by different factors such as individual variations, breed, and level of training (Barrelet and Ricketts, 2002). It is important to note the differences in normal values found in this study as compared with other reports (Hodgson et al, 2014;Souza et al 2016). …”

“…The groups treated with haylage presented a discrete decrease that persisted for three weeks (T1, T2 and T3). Mean values observed in both G1 and G2 ranged respectively from 200.43U/L to 259.97U/L and 138.39U/L to 230.23U/L, similarly to those reported by Souza et al (2016) of 140U/L and Padilha et al (2017) with means of 246.34U/L. According to Kaneko & Harvey (1997) all values remained within the normal range (226-366 U/L).…”

Clinical biochemistry profile of American Quarter Horse broodmares fed Tifton-85 (Cynodon spp.) hay and haylage

The conservation of haylage (a pre-dried feed) can be challenging, since there is an increased risk of mould growth, which can contaminate this foodstuff with mycotoxins. However, when the hygienic quality is secured, haylage enhances grass palatability and provide enough supply of dry matter throughout the year. Due to the lack of information regarding its effect on blood parameters in horses fed exclusively with this foodstuff, the aim of this study is to provide information regarding its use in comparison to hay and ensure that it does not affect horses’ biochemical profile. Twelve Quarter Horse broodmares were distributed into two groups, each fed with Tifton-85 (Cynodon spp.) hay or haylage for a period of 28 days, and the biochemical profile was done in five different times (T0 before the experiment started and, chronologically, seven days apart - T1, T2, T3 and T4), It was analyzed total protein (TP) and its fractioning; enzymes alanine aminotransferase, aspartate aminotransferase and γ-glutamyl-transferase; endogenous catabolism products urea and creatinine; and ions calcium and phosphorus. Mycotoxins in haylage were also investigated and remained below the legislation thresholds. Only TP was higher in the last sampling (T4) of the haylage group, which may be related to the foodstuff’s higher protein digestibility. No differences were observed between serum enzymes, urea, creatinine and Ca/P from both experimental groups. Haylage has proven to be safe, when well prepared for horses, without causing impairing side effects, as shown by the normal serum biochemistry parameters presented in this study.

“…The Campeiro horse is locally adapted in the Planalto Serrano Catarinense region (southern Brazil) and has a characteristic gaited to be credited to exist organic adaptations to the environment, as they were observed in other studies (Fonteque et al, 2016;Souza et al, 2016). Therefore, knowledge of protein fractions that make up the serum protein profile, its proportions and the influence of biological factors associated in sex, age, reproductive period (Miller et al, 1998), are necessary for knowledge of the physiologic standards of the race and its variations.…”

The aim of this study to measure the fractions of the total serum proteins of the Campeiro horse and identify the influences of biological variants. Blood samples were taken in 138 horses of the breed Campeiro for measuring the concentration of total serum protein by the biuret method. Serum concentrations of protein fractions were measured by electrophoresis using agarose gel. Groups were formed according to age, sex and reproductive condition. The average values of serum fractions: albumin (2.85±0.36g/dl), alpha 1 (0.28±0.11g/dl), alpha 2 (0.26±0.08g/dL) beta 1 (0.57±0.15g/dl), beta 2 (0.89±0.28g/dL), gamaglobulinas (1.86±0.34g/dL), albumin/globulin ratio (0.75±0.18) and 2.5% percentile and 97.5% had slight differences in relation to the reference interval proposed for the species. They observed higher values of alpha 1 and 2 globulins in the group from that had six to eight years old and gammaglobulins in group above 13 years old. Serum protein concentrations were similar in horses and mares and between non-pregnant and pregnant. Sex and pregnancy status did not affect serum proteinogram. Alpha and gammaglobulins have higher values as the age increases. Serum proteinogram of Campeiro horses shows variations that have to be considered in the interpretation of laboratory tests.
