… where 5 had TMR and 5 hade separate feeding of forage and concentrates. The milk yield and feed consumption was registered for one day at each herd. A comparison between the herds was made by using milk income minus the cost of the feed. The results show that the herds that used …
… a grazing management strategy that gives a high utilisation of grazed grass in milk production in the north of Scandinavia. To do this, a grazing experiment was planed and performed during the summer 2005. Simulations in the DSS were run to get a suggestion of how the cows …
… change in feed, environment, and new routines. There are indications that the milk somatic cell count (SCC) rises in a peak shortly after the let out. The purpose of this study was to see if peaks in the SCC could be observed after the let out, and to study the contribution of …
