Evaluation of selected agricultural solid wastes on biochemical profile and liver histology of Albino rats

Abstract

Wheat bran, groundnut shell, watermelon peel and corn bran were analyzed for chemical composition and amino acid profile. A feeding trial was conducted to assess their effect on biochemical profile and liver histology of rats. Watermelon peel obtained the highest dry matter content (91.93±0.03 g/100g), followed by groundnut shell meal (89.57±0.31 g/100g). Carbohydrate content ranged between 35.28±0.08 g/100g and 65.19±0.13 g/100g. Crude protein content ranged between 6.53±0.06 g/100g (groundnut shell meal) and 10.88±0.02 g/100g (wheat bran). Liver histopathology revealed normal architecture. The nutritional analyses of the wastes revealed rich nutritional content which may be explored for feed ingredient in livestock production. Further processing of these wastes may further enhance their nutritional composition; thereby providing alternative cheap animal feed for improved animal production and consequently improved animal protein consumption in developing countries.

Agricultural Solid Wastes: Causes, Effects, and Effective Management

“…A nonconventional feed ingredient, mycomeat has also been produced from agricultural solid wastes. The wastes served as substrate and a mixture of the substrates and the cultivated fungi (mushroom) was feed to broiler chicks, as a nonconventional feed ingredient, mycomeat [33,[35][36][37][38] fed some agricultural solid wastes to albino rats and recommended processing of the wastes in order to obtain a better result. Adebiyi et al [39] recommended the combination of 40% cassava peel +40% concentrate +20% watermelon wastes for feeding grower pigs.…”

Effects of extruded rice bran based diets on the performance, intestinal microbiota and morphology of weaned pigs

“…Effects of extruded rice bran based diets on the performance, intestinal microbiota and morphology of weaned pigs of a low-quality agricultural by-product to a high value feed source. The use of agricultural wastes and by-products as animal feeds in order to reduce cost of production and as an effective means of handling their disposal is encouraged (Adejumo et al 2017a;Adejumo et al 2017b;Adetunji and Adejumo 2017). The temperature reached by the feed during extrusion cooking can be as high as 200 °C but the exposure time at this elevated temperature is very short (5 s to 10 s).…”
