Produção e qualidade do leite de vacas da raça Holandesa alimentadascom silagens de grama estrela ( Cynodon nlemfuensis Vanderyst ) - DOI: 10.4025/actascianimsci.v29i1.261

Production and quality of milk from Holstein cows fed stargrasssilages (Cynodon nlemfuensis Vanderyst). The study aimed to evaluate animalperformance and quality of milk from Holstein cows during the final third period oflactation fed stargrass silages supplied with inoculant or urea in relation to corn silage.Stargrass silages with enzymatic-bacterial inoculant (80 g of additive/ton of silage), ureasupply (7 kg t -1 ) and corn silage were evaluated. Six Holstein cows with an average bodyweight of 480 kg were allocated in a double Latin square design (3 x 3). Corn silagepresented the highest values of DM, CP and NDF digestibility when compared to stargrasssilages. Supplying Holstein cows with stargrass silages with additive and urea did notpromote any effect on production and milk quality. Thus, it can be an alternative in animalproduction systems based on conserved roughage, depending on economical analysis for thereplacement of corn silage.
