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.
