“…The higher content of K in the R category (intact adult males) in the present study could be explained by the higher physical activity of rams during mating season. Since the slaughter was performed at the end of the mating season, greater physical activity during matting is implicated in the fatigue process, in which the K + ions are released from contracting muscles in the extracellular compartment [ 55 , 56 ]. Another possible hypothesis is that the higher content of K in R (intact adult male), compared to E (intact adult females) and W category (castrated adult males), is promoted by gender differences.…”

The aim of this research was to determine the effect of sex, castration, and processing on the chemical properties of mutton in the production of kaštradina—a traditional Dalmatian dry-cured meat product. Therefore, the carcasses of 20 ewes (E), 20 rams (R), and 20 wethers (W) of the Dalmatian pramenka breed were processed by dry-curing. On the 1st, 35th, and 60th days of processing, the samples from the scapulae were taken, then the proximate chemical, NaCl, and mineral analyses were performed, and significant differences between most of the parameters were found. Unlike W, the R samples contained significantly more proteins (p < 0.01), NaCl (p < 0.05), and potassium (p < 0.05) and less fat (p < 0.05). Furthermore, compared to the W and R categories, the E category of kaštradina contained significantly more calcium (p < 0.05). The higher contents of intramuscular fat, potassium, and calcium and lower content of NaCl could positively affect the sensory (marbling, flavor, juiciness, and tenderness) and chemical (fatty acid profile) properties of kaštradina. These findings suggest that the W and E raw mutton could be a better-quality raw material for production of kaštradina than could the R, but further research is needed for a more comprehensive picture of its quality.

“…The quantity of sweat was also correlated with PC1 (Discomfort; behaviours and facial expressions of discomfort). Sweat is a physiological reaction to exercise that is accompanied by ion loss and can disturb the body's acid-base equilibrium (Demirtaş et al, 2015). Although sweating is necessary to maintain a viable body temperature during exercise, extreme water loss through sweat may lead to physical tiredness.…”

“…Consequently, understanding horse responses to exercise is essential for detecting physical tiredness and exibly adapting training programs. In this study, we use the term "physical tiredness" to refer to physiological and behavioural responses to physical exercise, including potential alterations related to fatigue, de ned as the inability to maintain the intensity of a given exercise (Demirtaş et al, 2015).…”

“…Intense physical exercise challenges physiological equilibrium and induces physiological and behavioural modi cations (e.g., in horses (Allen et al, 2016;Lykkeboe et al, 1977;Poole and Erickson, 2011) and dogs (Poole and Erickson, 2011)). For example, in horses, intense exercise induces hyperthermia, accumulation of lactate (which breaks down into hydrogen ions and lactic acid), and changes in phosphate, calcium and potassium levels in muscle cells (Demirtaş et al, 2015). In humans, medium-term effects of intense physical exercise include sleep disturbances (Driver and Taylor, 2000), negative impacts on mood (Peluso and Guerra de Andrade, 2005), and reduced energy intake (King et al, 1994;Sim et al, 2014) that may cause weight loss (men (Staten, 1991)).…”

Physical activity, especially high-intensity exercise, leads to physiological and behavioural changes. The objectives of this study were to investigate i) the effects of physical exercise on weight, behaviours, and head and ear positions on the days after low-intensity training (LIT) or high-intensity training (HIT) and ii) if behaviours, facial expressions, and/or physiological parameters (sweat, salivation and blood lactate levels) during training predict post-training behaviours. A total of 19 French trotter horses housed in four different training centers were studied the day before (Dpre) and after LIT or HIT (afternoon after training (Dtraining) and 2 days after training (D1Post and D2Post)). The results showed that horses exhibited i) longer durations of resting and head below the withers (HBW) on Dtraining and D1Post than on Dpre and ii) shorter eating durations on D1Post and D2Post than on Dpre after HIT. This was associated with significant weight loss on D2Post. Several behaviours and facial expressions associated with discomfort (e.g., head conflict behaviours, nose behind the vertical, and opened mouth), as well as amount of sweat, predicted the durations of resting, HBW and eating on D1Post. Thus, behaviours are impacted by training, and a combination of behaviours, facial expressions and visible physiological parameters exhibited during training could predict physical tiredness in harness racing horses.
