摘要：Upgrading the nutritive value of sun dried Rumen Contents (RC) by enzymatic treatments and additives can make it a valuable feed resource for ruminants. The objective of this study was to determine the feeding value of partial replacement of Berseem Clover (BC) by treated RC with a mixture of exogenous enzymes (ZADO^® or ZAD^®) from anaerobic bacteria in the ration of early lactating Baladi goats. Twelve lactating Baladi goats weighed 26±0.5 kg in the first week of lactation were randomly assigned among four experimental treatments using 4x4 Latin square design to be fed four rations. 60% Concentrate Feed Mixture (CFM)+40% BC (Control); 60% CFM+20% BC+20% DRC (T₁); 60% CFM+20% BC+20% DRC treated with compound ZAD (T₂); 60% CFM+20% BC+20% DRC treated with ZAD compound+20 g compound ZADO /head/d fed directly before feeding (T₃). The period of this trial divided into four experimental periods each of 30 days. Results showed that T₃ and T₂ groups recorded higher values of digestibility coefficients compared with control and T₁ group. Groups contained DRC recorded higher values (p>0.05) of ruminal pH and non Protein Nitrogen (NPN) than the control. The treated groups (T₂, T₃) showed higher (p<0.05) values for rumen liquor ammonia, NPN and total volatile fatty acid s (TVFA's) (p>0.05) compared with untreated group (T₁). Results showed insignificant differences for blood serum total proteins, globulins, urea, Creatinine, Serum aspartate aminotransferase (AST), Alanin aminotransferase (ALT) and glucose. Biological treated groups (T₃ and T₂) increased (p>0.05) daily milk yield, 4%fat corrected milk (4% FCM), fat, Total Solids (TS), Solids Not Fat (SNF) and lactose yields compared with T₁ group. It could be concluded that feeding goats on rations containing DRC treated with ZADO and/or ZAD compounds as a partial substitute of berseem improved the performance of lactating goats without any adverse effect on animals’ health.
