Rumen impaction in sheep with indigestible foreign bodies in the semi-arid region of Nigeria

Postmortem Study on Indigestible Foreign Bodies in Rumen and Reticulum of Ruminants Slaughtered at Asella Municipal Abattoir, Southeastern Ethiopia

“…This is in contrast with the reports of Remi-Adewunmi et al [6]. However, higher prevalence of indigestible foreign bodies in female sheep and goats have also been reported by other authors [11,12,15,18,20]. This may be due to increased appetite of female animals and high nutritional demands during gestational period.…”

“…In contrast, most of small ruminant owners in this study area let their animal to forage on the highly polluted ground with no supplementary feed (Figure 4) their animals are likely to face a negative energy balance that will force them to ingest unusual materials including plastic, cloth, rope and even metallic objects Furthermore, most all bovine slaughtered in Asella municipal abattoir were male and this may also be associated lower prevalence in cattle. [11,12,[15][16][17][18]. This difference in the prevalence of foreign bodies between different areas may be associated with differences in animals' management system, age of animal slaughtered, sex and the extent of foreign body management between different study areas.…”

“…Other harmful effects of foreign body include reduced feed intake, failure to absorb volatile fatty acids, reduced rate of weight gain, internal injury, and death following obstruction of the intestinal tract [3,11]. Nonmetallic indigestible foreign bodies in the reticulorumen cause recurrent rumen tympany in adult dairy cattle.…”

Study on rumen and reticulium foreign bodies in cattle slauthered at Wolaita Sodo municipal Abattoir, Ethoipia

“…The ingestion of indigestible materials may occur during period of feed scarcity (Igbokwe et al, 2003). Reports from cattle and sheep reared within urban and sub-urban environments indicates that impaction of the rumen resulted from the accumulation of foreign bodies such as plastic bags interfered with flow of ingesta leading to the distention of rumen (Abdullahi et al, 1984;Igbokwe et al, 2003;Remi-Adewunmi et al, 2004).…”

The presence of foreign bodies in the rumen and reticulum also hampers the absorption of volatile fatty acids and consequently reduction in the rate of animal fattening (Igbokwe et al, 2003).…”
