protein synthesis, lowering metabolisable protein supply and milk output. These mechanisms originate under the maize silage cover, but their consequences are expressed at the feed bunk, in the milk tank, and ultimately, in farm profitability. From a production perspective, even relatively small energy deficits of 300 to 400 VEM per cow per day translate into measurable milk losses of approximately 0,7 to 1,0 litres per cow per day. When combined with intake limitations, these losses are often greater than expected and frequently only become visible once reflected in a declining milk yield. Under the silage cover lies either controlled performance or silent losses. Progressive dairy producers recognise that when transitioning to a new maize silage bunker, the ration must be reformulated accordingly; otherwise, the cows will make that adjustment themselves. Every newmaize silage stock is a new feed, so to ensure good, sound feeding of maize silage and to prevent any pit falls get practical tips and support from your local De Heus technical advisor and keep your cows healthy and productive – https:// www.deheus.co.za/meet- our-team/. www.deheus.co.za | 031 785 1575 | infosa@deheus.com www.agribonus.co.za Winter 2026 BONUS 119
