“…Basal plasma lactate values are <2 mmol/l in horses (Lumsden et al 1980;Moore et al 1980;Flisinska-Bojanowska et al 1991) and peritoneal fluid lactate concentrations of 0.7 ± 0.2 and 0.66 ± 0.43 mmol/l have been reported (Moore et al 1977;Parry and Crisman 1991). Plasma lactate is always higher in normal, resting horses than peritoneal fluid lactate (Moore et al 1977).…”

Summary Reasons for performing study: The most common cause of death as a direct result of colic is acute circulatory failure secondary to intestinal ischaemia. Early and accurate recognition of ischaemic bowel is essential to decrease complications and increase survival. Blood to peritoneal lactate values have been evaluated as a prognostic indicator, but lactate values characterised by type of lesion have not been reported. Hypothesis: Plasma and peritoneal lactate values are higher in horses with intestinal ischaemia secondary to a strangulating obstruction (ISSO). Methods: Venous blood and peritoneal fluid were collected sequentially from 20 clinically healthy horses and 189 horses admitted for colic during a one‐year period. Blood gas, pH, electrolyte (K+, Na+, Ca++, Cl‐), glucose and lactate values were determined for blood and peritoneal fluid samples; other values recorded for peritoneal fluid included gross appearance, total protein and nucleated cell count. Information regarding diagnosis, treatment and outcome was retrieved from the medical records. Results: Peritoneal and plasma levels of lactate were lower in control compared to clinical cases. Horses with ISSO had a higher peritoneal lactate value (8.45 mmol/l) than those with nonstrangulating obstruction (2.09 mmol/l). Factors with the strongest correlations with the presence of ISSO were changes in the gross appearance of the peritoneal fluid and values of peritoneal fluid chloride, pH and log10 lactate. Conclusions: Analysis of peritoneal fluid gross appearance, pH, lactate and chloride can be used for diagnosis of ISSO. Potential relevance: Peritoneal fluid lactate is a better predictor of ISSO than blood lactate and may aid in early detection of catastrophic peritoneal lesions such as intestinal strangulation and rupture.

“…In foals during the first three months of life, distinct disturbances in the acid-base balance was observed (Flisin´ska-Bojanowska et al 1991), with high levels of lactic and pyruvic acids, transitory metabolites in processes of energy freeing. The levels of pH, pO 2 , pCO 2 , lactic and pyruvic acids showed circadian rhythms in growing foals, with acrophases similar to those of their mother (Gill and Flisin´ska-Bojanowska 1994).…”

The presence of these rhythms underlay the high efficiency of homeostatic mechanisms in these animals despite the action of strong physiological factors as development of an organism.…”

This article reviews the literature on the daily rhythm in horses. Many physiological processes have been studied in horses to investigate their daily rhythmicity. In horses many rhythms are driven by an endogenous pacemaker, some of them endogenously generated, others influenced by external stimuli. It then addresses the influence of maturation and ageing, physical exercise and jet lag on these rhythms. The study of daily rhythms in horses is of considerable importance in all aspects of horse management to maintain the natural physiological behaviours of this species, necessary to guarantee the good welfare in breeding and athlete horses. Chronophysiology in horses also has clinical implications, it can influence disease occurrence, diagnostic tests and the effect of medical treatments.
