“…Concentrations of l ‐lactate and ammonia in the faecal water are practically not affected by the hay intake and so the differences in the faecel pH are probably caused by SCFA. Tisserand et al. (1980) found higher concentrations of SCFA in the caecum of horses when 3.0 kg hay plus oats (4 : 1) were fed compared with 3.5 kg hay/100 kg BW × day.…”

To investigate effects of hay intake and feeding sequence on indicators of the microbial activity within the hindgut, six horses were fed 1.00 kg oats plus 0.50, 0.67, 0.83 or 1.00 kg hay/100 kg body weight (BW) · day, each for 14 days. Oats was offered either 30 min prior to hay (OA) or in the reversed sequence (HA) in a 2 · 8-week crossover design. Because typically exercised horses should be subjected to the study, faeces was used as substrate. Faecal dry matter (DM), the faecal watersÕ short-chain fatty acids (SCFA, in mmol/l) and molar percentages (mol%) of propionate and iso-butyrate were highest with OA (p < 0.01). Acetate mol%, acetate-propionate quotient (A/P) and buffering capacities 1 and 2 (BC1: current pH to pH 6; BC2: pH 6 to 5) of the faecal water were highest with HA (p < 0.01). While the hay intake rose, faecal pH, acetate mol%, A/P, BC1 and BC2 (the latter with HA only) increased (p < 0.05), but DM, SCFA and propionate mol% declined (p < 0.05). The hay-induced rise in A/P and BC1 was much higher with HA than with OA. l-Lactate and ammonia were unaffected by the feeding sequence and hay intake. In conclusion, hay intake and feeding sequence influence the microbial activity within the hindgut, although the concentrate level remains consistent. In horse rations with 1.00 kg oats/100 kg BW · day amounts of at least 0.83 kg hay/100 kg BW · day and offering the hay first seem to have the potency to protect the hindgut content from acidification. Behavioural abnormality was not observed any longer first with 1.00 kg hay/100 kg BW · day.

Vergleichbar der Pansenacidose des Rindes kann so bei stär-kereicher Fütterung und der geschilderten Disposition des Pferdes über den Substrat-und den damit verbundenen pHEffekt (Abel et al 1990) eine überstimulierte mikrobielle Aktivität im stark besiedelten hinteren Verdauungstrakt zu klinisch relevanten acidotischen Milieuveränderungen führen.…”

ZusammenfassungIleum und Caecum des Pferdes markieren den Übergang der zwei großen Verdauugsräume: Magen-Dünndarm-Bereich mit überwiegen-der Verdauung durch körpereigene Enzyme und Dickdarm mit seinem umfangreichen, mikrobiell vermittelten fermentativen Potential. Das Ileum imponiert funktionell vor allem mit einer hohen Motilität und der Fähigkeit, den Dünndarmchymus in das Caecum weiterzuleiten. Dieser Entleerungsmechanismus ist allerdings sehr störanfällig. Im Caecum wiederum weisen Besatzdichte, Artenspektrum und Aktivität der Mikroorganismen eine bemerkenswert enge Beziehung zum Nährstoffangebot über die ileocaecal passierende Ingesta auf. Diese "Fütte-rungsabbhängigkeit" birgt ein hohes Risiko für Dysbiosen mit enteraler (z. B. Kolik, Diarrhoe) und extraenteraler (z. B. Hufrehe) Ausprä-gung. Hinsichtlich der Aufrechterhaltung physiologischer Bedingungen in beiden Darmteilen sind jeweils verschiedene Fütterungsfaktoren von Bedeutung.Schlüsselwörter: Pferd, Ileum, Caecum, Motilität, Intestinalflora Physiology of the digestion in ileum and caecum in the horseThe passage from ileum to caecum represents the border between the mainly enzymatic digestibility in the lower gut and the highly developed microbial fermentation in the hind gut. The transfer of digesta from the terminal lower gut into the caecum is the main physiological function of the ileum and highly endangered by disturbances. Within the caecum, microbial population and it's activity are dependent on the nutrient composition of the ileal digesta. These dependency causes a risk potential for developing a defective fermentation with the possible result of enteral (e. g. colic, diarrhoea) as well as extraenteral (e. g. laminitis) disturbances. To maintain physiological conditions feeding practice should consider the specific requirements of the individual gut segments.
