“…The main work, so far, has been centred on the periodicity of the excretion of the two types of faeces, whether it is induced by an endogenous clock, or by external factors such as food intake or day-length (Watson, 1954;Heisinger, 1962Heisinger, , 1965Hornicke & Batsch, 1977;Jilge, 1976Jilge, , 1979a.

“…For example, Lockley (1964) notes that he never saw the wild rabbits discard faeces in the burrows in the course of a four-year observation period. Heisinger (1962Heisinger ( , 1965 regarded the 4-or 5-h period after the reingestion of the last soft faeces until the evening, during which fresh food was not eaten and only hard pellets were in the rectum, as a fasting period. This interpretation is based on the assumption that hard faeces are not reingested and it may be unjustifiable.…”

Coprophagy in the Japanese hare (Lepus brachyurus): reingestion of all the hard and soft faeces during the daytime stay in the form

The daily rhythms of formation and reingestion of hard and soft faeces were studied in Lepus brachyurus. Although the Leporidac have long been known to reingest soft faeces, the Japanese hare also reingests a substantial amount of hard faeces. All the faeces excreted during the daytime stay in a form, comprising first hard faeces, then soft faeces and again hard faeces, were reingested. Hares repeatedly sit straight up from the squatting position to practise reingestion. A reingestion bout for hard faeces consists of repeated faeces‐taking actions each followed by mastication, whereas that for soft faeces includes only one faeces‐taking action without mastication. If deprived of food during foraging at night, the Japanese hare reingested most of the faeces that were normally discarded. Evidence in literature indicates that other Leporidae also practise reingestion of hard faeces.

Colonic Separation Mechanism in Lagomorph and Rodent Species - a Comparison

Small hcrbivorous animals living on coarse food during cold or dry periods require a mechanism to be able to eat large quantities of food without losing the micro-organisms they need for fermentation. They use colonic separation mechanisms (CSM) that allow rapid transport of the less digestible food particles through the digestive tract whilst at the same time they retain micro-organisms and easily digestible food particles in their caecum for sufficiently long time periods in order for fermentation and microbial reproduction to take place. As a result of CSM, micro-organisms accumulate in the caecum. All species provided with a CSM utilise microbial proteins and vitamins via caecotrophy. A comparison is made between species belonging to the order Lagomorpha (hare, rabbit, pika) and species belonging to two suborders of Rodentia [myomorph rodents (rat, lemming, vole) and caviomorph rodents (guinea pig, chinchilla, nutria)].The effects of the CSM are similar amongst the species studied, however, the efficiency of the CSM differs between individual species independent of the orderisuborders to which they belong. The anatomy of the caecum and proximal colon is similar within the lagomorph order, but different compared to the rodents. It is more or less similar within each of the rodent suborders but differs between suborders. The mode of trapping and returning micro-organism is similar in myomorph and caviomorph rodents but different compared to the lagomorph species. Outside of the lagomorph and rodent orders CSM producing similar effects are found only in a few marsupial species. The anatomical and physiological background of the CSM in these species is not known.
