Microbial populations in herbivores gut attack, degrade and ferment structural carbohydrates in forage cell walls, producing volatile fatty acids and microbial proteins for the host. Exocellulases, endocellulases and cellobiases are the major cellulolytic enzymes while hemicellulase (xylanase) exposes cellulose for fermentation. This study aimed to isolate proteins that hydrolyse fibre or assist fibrolysis in any way... Read more.

Polyphenols are the second largest abundant organic molecules in nature. One of the principal reported biological activities is the antioxidant capacity. 2,2-Diphenyl-1-picrylhydracyl (DPPH) method has been used to quantify polyphenols antioxidant activity in many different products with reproducible and reliable results. We proposed and validated a methodology to analyze this antioxidant activity with smaller amount of... Read more.

High content of total fatty acids (TFA) was found in fat (62.06 ± 3.4 g/100 g) followed by liver (50.68 ± 4.72 g/100 g) and muscle tissues (10.9 ± 0.81 g/100 g). Saturated fatty acids (SFA) formed 72.9% TFA in the... Read more.

The nutritive value of corn cob following pretreatment by fermentation with fungal species of Lachnocladium spp. was investigated. Corn cob was milled and subjected to incubation with fungal species for a period of one week. Significant increase (p<0.05) in protein, ash and some mineral elements were observed. Calcium, magnesium, zinc and sodium content were observed to be higher in fermented cobs while significant... Read more.

Antioxidants are beneficial compounds found in a lot of foods. Cordia africana (Lam.) is a small fruit eaten all over Tigray and other parts of Ethiopia. The fruit was tested for its antioxidant content using the ferric reducing antioxidant power (FRAP) assay and total phenols (TP) measured with Folin Ciocalteu`s reagent, across four different agroecological zones and three land use classes in Tigray. The average FRAP... Read more.

Obesity increases the risk of developing a number of diseases such as insulin resistance, type 2 diabetes, hypertension, hypercholesterolemia, stroke and heart attack. The aim of this study was to investigate the impact of ethanolic root bark extract of Anthocleista vogelii on weight reduction in high carbohydrate diet (HCD) induced obesity in male Wistar rats. Thirty male Wistar rats were housed in three... Read more.
