Contenido :  Feed efficiency is a most common method to determine biological efficiency of milk production. One way to increase feed efficiency is to balance rations and make more strategic use of supplement. Admore, it is known that cows selected for milk yield have a higher feed efficiency when fed well-balanced diets ad libitum, but it is not clear how it is affected as pasture is included in the diet. Thereby, the aim of this study was to quantify the effect of feeding strategy (FS) and cow genotype (G) on individual animal performance and feed efficiency in pasture-based feeding systems during spring. The experiment was a randomized complete block design, with a 2?×?2 factorial arrangement of treatments, combining feeding strategies and Holstein Friesian cow genotypes.

Contenido :  Abstract: Aims: The Rio de la Plata grasslands are one of the largest areas of temperate humid and sub-humid grasslands of the world. A substantial fraction of these natural grasslands are preserved in Uruguay, occupying more than 60% of the country. So far, Uruguayan grasslands have been indirectly classified using only geomorphological and edaphic criteria. An adequate description of vegetation heterogeneity is a prerequisite to study ecosystem function and to design management and conservation strategies for this region. To this end, we present a classification of the natural grassland communities of Uruguay based on a wide and comprehensive set of phytosociological relevés. Study area: Uruguay. Methods: Three hundred eight grassland relevés were utilized for classification and ordination multivariate analyses. Agglomerative clustering based on the flexible Beta linkage method and Sørensen distance measure were employed to identify relevé groups. Indicator species analysis was also performed to identify diagnostic species. We used Non-metric multidimensional scaling to determine the main floristic gradients. Results: Five communities and 14 sub-communities were identified. Two of the communities were restricted to the ?Basaltic? region of central and northern Uruguay, while the other three were distributed through the Eastern Hills, North Eastern Sedimentary Basin and the South Central regions. Three of the communities correspond to densely-vegetated grasslands associate... Presentar Todo
