The aim of this paper was to select atmospheric factors and their values, which may disrupt the correct behavior and physiological condition of recreational horses. The studies were carried out from 1 July until 1 September on 16 Anglo-Arabian geldings. Each day, from 09.00 to 10.00 hours, the horses worked under saddle. The riders and the authors gave a qualitative behavioral assessment for each horse. Mood and willingness to work were evaluated. The quantitative assessment was called 'incorrect behavior of the horse while riding' (IBHR). The percentage time of duration and the number of occurrences of the features while riding were calculated. Heart rate, body temperature and respiratory rate were taken at 08.00 hours (resting measurement) and at 10.05 hours (post-exercise measurement). Air temperature, relative air humidity, wind speed and atmospheric pressure were measured at 08.00 and 10.00 hours. The results showed that adverse changes in the behavior of recreational horses can occur if the horse is ridden when the air temperature is above 26°C and when wind speeds exceed 5.5 m/s. Such conditions may cause a reduction in the mood and willingness to work in horses. Physiological parameters like heart rate and body temperature seem to be more sensitive indicators of the horse body reaction to the weather than behavioral reactions.

“…Given that these studies were limited to elite races run over middle and long distances, our results are broadly consistent (in terms of improvement rates) even if our qualitative conclusion-that horses are still getting faster-is different. The qualitative discrepancy likely reflects our greater statistical power combined with explicit modelling of environmental factors known [10] or hypothesized to influence speed. Ongoing improvement in sprint performance, not previously analysed, is much more rapid.…”

Previous studies have concluded that thoroughbred racehorse speed is improving very slowly, if at all, despite heritable variation for performance and putatively intensive selective breeding. This has led to the suggestion that racehorses have reached a selection limit. However, previous studies have been limited, focusing only on the winning times of a few elite races run over middle and long distances, and failing to account for potentially confounding factors. Using a much larger dataset covering the full range of race distances and accounting for variation in factors such as ground softness, we show that improvement is, in fact, ongoing for the population as a whole, but driven largely by increasing speed in sprint races. In contrast, speed over middle and long distances, at least at the elite level, appears to be reaching an asymptote. Whether this reflects a selection limit to speed over middle and long distances or a shift in breeding practices to target sprint performances remains to be determined.

ESTIMATION BREEDING VALUE AND MPPA (Most Probable Producing Ability) OF RACEHORSES BASED ON NATURE OF RUNNING SPEED. The aim of this study was to obtain the estimated number of breeding values from the racehorses parent in Minahasa for racehorse selection based on the superiority of genetic traits of speed. The descriptive analysis such asaverage, standard deviation and coefficient of variation of the speed and performance were done as the first step. Heritability, ripitability and the probability of breeding value (PBV) were calculated after all. The results of this study indicate that the value of heritability and repeatability obtained varies from low to high. The highest estimation of breeding value (PBV) for male (H), the highest MPPA (Most Probable Producing Ability) value in the population (individual B010) and the average MPPA value for the entire population were 0.0869, 0.1845 and 0.0239 respectively. The conclusion of this study puts the racehorse with the name "Swift Jhon" and "Super Princes" as males and individuals who have an average increase in the nature of the highest running speed.
