AbstractThe objective of this study was to evaluate the effect of protected soybean meal (SBM) on total milk yield (TMY) and composition, milk energy and body weight (BW) in lactating Meriz does. Eighteen does (BW 33.13±0.41 Kg) were randomly divided into two equal groups, control (untreated soybean meal) (C) and the treated soybean meal chemically treated with formaldehyde (T). Results revealed that protected soybean meal significantly (P<0.001) increased TMY (44.20 vs 34.08 kg), milk fat % (4.14±0.13 vs 3.32±0.06), and yield (25.45±0.75 vs 16.08±0.41 gm/day) , milk protein % (4.86±0.05 vs 4.31±0.04), and yield (30.73±1.02 vs 20.99±0.52 gm/day), and milk energy (3.38±0.05 vs 3.03±0.02 MJ/kg) as compared to control. It can be concluded that protection process of soybean meal increased milk yield, fat and protein content.
