Three different berseem silages were evaluated in this study. Berseem was chopped into 3-5 cm, then sun dried to get wilted berseem silage (S1) or mixed with ground barley grains (S2) or ground com grains ($3) at 75:25%. Part from each type of silage was packed in double layer bags (50 Kg each for exp. 1) and the other part was kept in over ground silo (for exp. 2) for 70 days. Two experiments were carrled out to: 1) evaluate the quality and nutritive value of different silages via laboratory analysis and digestion trials using three adult male balady sheep in a Latin square 3x3 design (Exp. 1). and 2) compare the effect of feeding berseem silage with berseem hay rations on the performance of milk production using four lactating Holstein Friesian cows in "Swing Over" design (Exp. 2). ‘ = ‘ Data indicated that corn-berseem silage (83) had the best silage characteristics, nutritive values and nitrogen balance compared with other barley- berseem silage (S2) or wilted berseem silage (S1). Cows fed ration contained 83 produced more milk than those fed ration contained berseem hay. There were insignificant differences in milk composition between cows fed berseem hay or corn- berseem silage rations. except that there was a significant increase in solids not fat and ash content in milk of cows fed corn-berseem silage ration. Also, the lowest feeding cost per 1 kg 4% fat corrected milk was observed in feeding corn-berseem silage grOUp being 0.72 L.E. compared to 0.89 L.E. in berseem hay group. In conclusion, feeding dairy cows on corn-berseem silage may improve the performance of milk production and decrease the cost of milk production.
