Produção, composição, consumo e digestibilidade em vacas recebendo milho reidratado e ensilado com silagem de cana de açúcar como volumoso

Abstract

replacement. Cows that were fed diet 100% replacement had higher milk yield, fat corrected milk yield, fat yield, protein, casein and lactose higher compared to the control diet. The apparent digestibility of dry matter, ether layer, total carbohydrates, no fiber carbohydrates, organic matter, crude protein and starch was higher in cows fed the diet with 100%replacement diet compared with 0% replacement of SRM by DGC. The relative production of propionic acid was higher and the concentration of NH 3 -N was lower 3 h after feeding in ruminal fluid for cows fed the diet 100% replacement diet compared with 0% replacement.The relative production of propionic acid was higher and aconcentração of NH 3 -N was lower 3 hours after feeding in ruminal fluid for cows fed diet 100 % replacement diet cm compared to 0 % replacement. The time of ensiling progressively operates the degradation rate of MS MRE. Also complete replacement of DGC by REC in the diet of dairy cows increased intake, digestibility, milk yield and solids decreased the ammonia concentration and increased the proportion of propionic acid in the rumen fluid.
