Nutrient intake and blood profile of Nellore calves supplemented with cellulolytic fungi from rumen

This study evaluates the effects of cellulolytic fungi from rumen on nutrient intake and blood profile Nellore calves. A diet was formulated with 56.79% lignified hay Urochloa brizantha 43.21% concentrate. Sixteen calves were evaluated in completely randomized blocks using two calf groups: four males females. The first group supplemented a culture medium containing mixture Aspergillus terreus (VN 15 isolate) Trichoderma longibrachiatum 20 isolate). second received sterile only. Ether extract ingestion higher control calves; however, showed tendency to improve feed efficiency. No significant differences detected profiles or serum biochemistry between groups. Further research analyzing different dosages, adjusting protein levels, increasing proportion roughage could better elucidate interference these performance parameters weaned
