| Successful grazing when using AMS is possible without having to devote a great deal of time to organize and fetch cows every day. However, a careful strategy and good infrastructure, and observation of cow behaviour and pasture are necessary, and the herd has to adapt to the chosen design and routines. In practice, sectional permanent grazing, part-time grazing and structured rotational grazing have been shown to be successful, in terms of allowing outdoor grazing while still maintaining milking frequency and milk yield. In addition, part-time grazing can be combined with either of the other two systems. |

| The objective of this research, was to quantify sustainability indicators of organic dairy farms using Automatic Milking Systems (AMS), and a comparative group of organic dairy farms using conventional milking systems (CMS). Milk yield per cow was higher for AMS farms but did not result in higher net return to management. Nitrogen surplus per ha of available land was higher for AMS farms, Animal health was unaffected by AMS use, as also most milk quality aspects; somatic cell count, clostridium spores and urea. Acid degree value (ADV), measured as free fatty acids (FFA) in the milk, was higher in milk from AMS users. Labour time was decreased by almost 50% for AMS users, to 2.3 min/cow/day. It could be concluded from quantification of selected indicators... |
