Abstract: Three cannulated buffaloes (male calves) and eighteen mature Ossimi rams were used in two trials to evaluate different treatments of berseem silage production for ruminants feeding. In addition, nine and twelve lactating buffaloes were used in the third trial (experiment 1 and 2). In a primary study, (first) In-situ technique was used to determine DM and OM disappearance for berseem (Trifolium Alexandrinum) as fresh; (B), hay (BH) and ensiled with one of different additives [ground corn5%; (BSC), molasses5%; (BSM), whey10%; (BSW), formic acid 0.4%; (BSF) or without additives; (BS)] by the nylon bag technique. The second trial, metabolism experiments were conducted to evaluate the digestibilities, feeding values and some rumen parameters using the same previous berseem hay and additives. The third trial was conducted to investigate milk production and composition, experiment (1) was carried out to study the effect of replacing roughage with berseem silage with two R : C% ratios. Experiment (2) was conducted using the same previous berseem additives. Ensiling characteristics indicated that the smell of all silages was good and the color of all silages was light green especially berseem silage with whey as an additive. However, whey did not prolong the stability when out of the silo. The lowest pH value was found in (BSF) and the highest value in (BS). Values of ammonia-N in silage were lower for BSF than others. The lactic acid percentage was the highest for (BSF). DMD% after 48 hrs incubation times for BSW was the significantly lowest value (p<0.05) among all treated silages or fresh berseem. Digestibility of DM and NFE were significantly the highest (p<0.05) values for BSC. No significant differences (p>0.05) were obtained for digestibilities of CP, and CF for different berseem silage additives and berseem hay in experimental rams. No significant differences were observed for both TDN and SV values. Berseem silage with molasses recorded a higher significant DCP than berseem silage with no additives. The highest (p<0.05) rumen acidity and TVFA’s were caused by BSM treatment and the lowest acidity was recorded for the BS treatment. The highest milk yield was recorded for 75:25%; berseem silage to concentrate ratio. Milk production increased with ground corn and whey as a silage additive than others.
It was concluded that berseem silage with different additives was good quality and digestibility when compared with silage with no additives. Milk yield was increasing with increasing silage intake. In addition, using whey as a silage additive was benefit to increasing milk yield and was the most efficient economic treatment.
