Substitution of concentrate mixture with dried brewery spent grains improved biological and economical performance of 50% Dorper × Menz crossbred sheep.

The study aimed to investigate the potential of dried brewery spent grains (DBG) to substitute concentrate mixture (CM) in a diet of growing 50% Dorper × Menz crossbred ram lamb. Randomized complete block design (RCBD) was used for this study, and experimental animals were stratified into 7 blocks based on their initial body weight and age. Ram lambs from each block were randomly assigned to one of the five treatments.
