One of the biggest variable costs on livestock farms is undoubtedly feed costs and figures are often quoted that grazed grass is the cheapest feed on the farm. However, if we all agree that grazed grass is the cheapest feed on a farm then one target should be to maximise its use. The second obvious target alongside that is to maximise the use of grass silage in those periods when grazed grass is not sufficient to meet the needs of the stock on your farm. There are many choices to be made when considering grass silage the first being whether to bale or to clamp.
Negative energy balance during early lactation is a demanding physiological state for the cow at the best of times, and can be made worse through the feeding of butyric silage. The cow’s liver requires optimal condition as the demand for glucose increases from 1kg/d in late gestation to 2.5kg/d 3 weeks post calving. A successful transition determines the success of the subsequent lactation, with energy levels crucial to immune function during the transition period. The feeding of butyric silage, however, can increase the risk of ketosis in cows at all stages of lactation. This is often referred to as type III ketosis, which is the focus of this article.
Having a plan to harvest some of your cereal crops for whole-crop cereal silage is a "no brainer" if you need to top-up tight grass silage stocks on dairy and other livestock farms, says silage specialist, Derek Nelson.
