During participant interactions with horses, it is important to consider the risks that equines pose as they are animals prone to fight and flight behaviors. The Professional Association of Therapeutic Horsemanship International recommends that equines should be evaluated for suitability to participate in EAS prior to their participation so that the risks associated with equine-human interactions can be properly managed. To assess equines for EAS, the Basic Ground Skills Assessment (BGSA) was developed and subsequently tested for validity and reliability. Fourteen lesson horses were assessed on BGSA competencies by an EAS professional. Heart rate, an indicator of stress levels that is correlated to safe and unsafe equine behaviors, was collected throughout the testing and compared to each horse’s average BGSA scores as assigned by the rater. This comparison demonstrated that the BGSA was a valid (r = −0.947, p < .001) predictor of equine stress levels and thus a valid indicator of horse behavior. Additionally, two EAS professionals rated a horse using the BGSA to determine inter- and intra-rater reliability. Score comparisons revealed that inter-rater reliability was moderate (κ = 0.769; p < .018) and intra-rater reliability was moderate (κ = 0.769; p < .018).

The goal of this study was to evaluate hematologic, clinical chemistry, and physical parameters of eight female SAFS from coastal Uruguay.

The mean aspartate aminotransferase (AST) was similar to that reported previously for females and pups, except two females that showed higher levels.

This study examined the effects of synbiotic supplementation on selected antioxidant markers and immune response in Murrah buffalo calves. A total of twenty-four Murrah buffalo calves aged 5–7 d were enrolled randomly into three treatment groups based on body weight (BW) in a sixty-day feeding trial. Treatments were (1) control (CON); basal diet with no supplementation; (2) SYN1; control + synbiotic formulation 1 (200 mL fermented milk prepared from Lactobacillus acidophilus NCDC15 + 8g Cichorium intybus root powder); (3) SYN2; control + synbiotic formulation 2 (200 mL fermented milk prepared from Limosilactobacillus reuteri BFE7 + 8g Cichorium intybus root powder). Supplementation of SYN1 and SYN2 to calves significantly improved (P < 0.05) the cell-mediated immune response to phytohaemagglutinin-P (CMI; delayed type of hypersensitivity response to PHA-P). At the same time, the humoral immune response to chicken RBC (HIR; antibody titre to C-RBC) was enhanced (P < 0.05) in SYN-fed calves than in CON calves. Moreover, increased superoxide dismutase and catalase activities (P < 0.05) were observed in synbiotic-fed calves compared to CON calves. However, glutathione peroxidase activity was not influenced by SYN supplementation.
