“…The field of physiology was the first to be explored in this rodent, with a report by Ewer on the form and function of the GCR describing its structural and behavioural primary feeding adaptations. No other significant contribution was made in this field until 43 years later when Yapi et al provided more insight into the physiology of this rodent, highlighting the caecum as an important site for fermentation in digestion.…”

Background: The greater cane rat (GCR), reputed to be African's second largest rodent, is a precocial hystricomorph with an uncommon phenotype and life history. Scientific and socio-economic interests in the GCR have led to heightened research efforts targeted towards a better understanding of its biology and exploration of its economic and translational usefulness.Methods: Records of all online scientific publications on the GCR from Google, Google Scholar, PubMed, science.gov, Ebscohost and Worldwide science, with the exception of research theses, proceedings, unpublished projects and abstracts, were collated and analyzed using descriptive statistics. Results:A total of 146 published scholarly articles spanning about six decades were retrieved, with 98% of the GCR publications originating from African countries. Nigeria boasts the highest number of publications (58.22%) followed by Ghana (21.23%) and South Africa (5.48%) while Senegal contributed the least (0.69%).Publications were sorted into ten field categories. The field with the highest number of articles (41.78%) was animal breeding and management recording, closely followed by anatomy (37.67%). Lesser contributions were made by parasitology (5.48%), biochemistry/hematology (4.8%), pharmacology/toxicology (4.11%), pathology (2.06%), and surgery/anesthesia and physiology (1.37% apiece). The fields with fewest contributions were microbiology and developmental biology (0.69% each). Conclusion:This study chronicles the spectrum of knowledge available on the GCR, highlighting the knowledge gap that still exists in various fields in order to provide advocacy for new frontiers in research efforts on this rodent. We suggest the need for a clearly defined and well integrated national/regional policy aimed at establishing Africa's foremost micro-livestock rodent, the greater cane rat, on the world's scientific radar.

“…Anatomically, the stomach was divided into three regions: cardia, body, and fundus. The stomach displayed two curvatures, the greater and lesser curvatures, which have been previously described by Yapi et al (2012) [36] and Scopin et al (2011) [37] in rats. Cooper and Schiller (1975) [22] described the guinea pig stomach as having two curvatures, the greater and lesser curvatures, and four regions, a cardia, a fundus, a body, and a pylorus.…”

Although the Genus Oryzomys is widely distributed in the Americas, there are very few published data on the morphology of this rodent group. Notably, in relation to the digestive apparatus, the data are sparse and fragmented. In addition, because rodents are important animal models, this information may be useful in recent and promising areas for applied studies, such as clinical, therapeutic, and surgical models. Here, we describe the morphological characteristics of the digestive system in Oligoryzomys nigripes using gross morphology and light and scanning electron microscopy. In total, five specimens were used. After an incision from the oral to pelvic cavities, all organs of the digestive system were exposed and dissected. Next, all structures from the oral cavity, pharynx, esophagus, stomach, intestines, liver, and pancreas were processed and evaluated by microscopy. The results revealed that the digestive system of O. nigripes consisted of an oral cavity, in which the tongue, minor and major salivary glands, and dental arch were predominant. Behind the oral cavity, the pharynx, esophagus, stomach, intestines, liver, and pancreas were identified and presented typical morphological characteristics of rodents. In conclusion, our results suggest that the morphology of the O. nigripes digestive system differs from the previously described data for other rodent species, mainly due to the absence of the molar teeth and gallbladder in this species.

“…Several studies have been carried out in order to develop such feed but nutritional requirements of the cane rat remain largely unknown. Concerning dietary fibres for instance, recent studies showed that the cane rat can digest relatively high amounts of fibres [15], due to its well developed caecum [16], but the optimum of fibres levels in the diet suitable to each physiological stage of this animal remain largely unknown.…”

In order to increase animal protein self-sufficiency, the government of Ivory Coast chose a policy of livestock activities diversification including the promotion of mini-livestock such as cane rat husbandry. Today, cane rat breeding has a craze among Ivorian people, but it struggles to really take off. With the aim of contributing to an optimal development of cane rat husbandry in Ivory Coast, we performed a diagnosis of the breeding systems in order to determine the factors that hinder the proper development of this activity. The diagnosis was performed using a survey questionnaire. The survey was carried out using the Participatory Rapid Appraisal Method. Sixty-six farms in 13 administrative Regions of Ivory Coast were investigated. The results showed that most of breeders (55%) were well equipped with livestock buildings in modern materials. However, the animal feeding system was inadequate, characterized by crude protein deficiency. The poor quality of the feed associated with an approximate hygiene management led to high mortality of the animals, reaching over 60% in many farms. The development of complete pelleted diets suitable to the cane rat digestive physiology, with a better control of animal health should allow cane rat breeding to take a jumpstart in Ivory Coast.
