PROXIMATE COMPOSITION OF GREEN OFFAL (STOMACH AND INTESTINE) FROM CATTLE, SHEEP, GOAT, AND CAMEL

Abstract

The study assessed the proximate composition of green offal (stomach and intestine) from cattle, sheep, goat, and camel to evaluate their nutritional value and potential for dietary applications. Samples of the stomach and intestine were obtained, cleaned to remove debris, boiled, and analysed for proximate composition following standard AOAC methods. Data were statistically analysed using the general linear model procedure, and significant differences were compared using Duncan’s multiple range test. The results revealed significant variations in proximate composition influenced by both animal species and offal parts. Among the species, goat and camel offal exhibited the highest protein content (27.81 and 27.50%, respectively), while sheep offal showed the highest lipid content (7.74%). Conversely, the lowest protein (22.43%) and lipid content (5.01%) were recorded in sheep and cattle offal, respectively. The stomach had higher dry matter (48.14%), lipid content (8.84%) and crude protein content (25.59%) compared to the intestine with values of 45.82%, 6.70% and 25.01%, respectively. Intestine contained higher nitrogen-free extract (4.92%) compared to the stomach (4.39%). Ash content was not significantly different (P>0.05) across the offal parts. The study concludes that goat and camel offal were superior in protein, nitrogen-free extract contents, while sheep and goat offal exhibited the highest lipid levels. The stomach generally contained higher dry matter, lipid and protein contents than the intestine. Hence, efforts should be directed on promoting the utilization of green offal, particularly goat and camel offal, as a sustainable and affordable protein source.
