Nine Baladi goats of 23.80.4 kg of BW were divided into 3 groups of 3 goats. The goats were housed in tie stalls with free access to water. Three diets were formulated with 50:50 (DM) forage:concentrates ratio to meet their nutrient requirements when fed at 3% of BW (which was changed continuously based on changes in BW; Khattab et al., 2011). The Control diet consisted of Egyptian berseem clover (Trifolium alexandrinum) and concentrate mixture on a 1:1 DM basis. The other two diets contained 0.25 (SRS25) and 0.45 (SRS45) (w/w, DM basis) of SRS. Diets were fed to each goat at 08:00 and 16:00 h in equal portions. The ingredient and nutrient composition of the diets are in Table
