Sward allowance at early lactation of primiparous dairy cows: Ⅰ‐Milk yield and composition
Grazing the whole year round represents the dominant feeding system in Uruguayan dairies.The inter‐relationship between pasture and the grazing ruminant is a dynamic, two‐way process.The quantitative, qualitative and structural aspects of the different plant species present in the pastures influence the plant material ingested by the animal, which in turn modifies the plants remaining and their subsequent production and fate (Chilibroste et al., 2005 ).Farm surveys carried out at dairy farms in Uruguay have shown that individual milk production levels are under the breed milk production potential, specially in first lactation dairy cows (Chilibroste et al., 2004).This experiment was carried out to understand the impact of daily sward allowance on milk production and composition of early lactation first calving dairy cows grazing temperate pastures.
