ABSTRACT


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 260.5 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 CFM40 BC Control 60 CFM20 BC20 DRC T1 60 CFM20 BC20 DRC treated with compound ZAD T2 60 CFM20 BC20 DRC treated with ZAD compound20 g compound ZADO headd 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 p0.05 of ruminal pH and non Protein Nitrogen NPN than the control. The treated groups T2, T3 showed higher p0.05 values for rumen liquor ammonia, NPN and total volatile fatty acids TVFA's p0.05 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 p0.05 daily milk yield, 4fat 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 andor ZAD compounds as a partial substitute of berseem improved the performance of lactating goats without any adverse effect on animals146 health.
