Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient …

… to the cattle. Both the nutritional and hygienic quality is crucial to a high milk yield and a good health in your stock. If the silage process is unsuccessful you may have to use this feed during the whole season, just because you don’t have anything else to use for silage …

… themselves by grazing. This saves both money and time. According to research milk yield decrease with an increasing proportion of pasture in the diet. This is because cows on pasture will have lower dry matter intake than cows with supplements. On a pasture-only diet, high …

… Prolonged daily rumination was positively correlated with higher milk yield and long daily rumination was also positively correlated with extended the inter-cycle periods.

… of imprinted genes have been found in livestock that affect traits such as milk yield, growth and carcass traits, fat and meat deposition and fetal development. The implementation of breeding programs taking imprinting into account, will require changes in the current standard …

… is unknown. The dairy cattle of today live a stressful life, as their high milk yields forces them to eat large amounts of feed and spend a great portion of the day ruminating. Do they have time to get enough sleep? Which factors affecting the need of sleep in dairy cattle are …

… has a moderate to high heritability and is also highly genetic correlated to milkability, milk yield, growth and carcass traits. The feeding behaviour does not differ much between different individuals or breeds. The rank order is positively correlated to body size within breed …
