Request a silage analysis for nutrients and minerals.
You will be feeding it soon, if you have not already opened the pit.
2017 grass silages are not testing as well as we would like, due to the slightly delayed first cut. It is highly recommended that you test your silage before you buy concentrates, so that you are balancing it properly. Grazed grass dry matter is 12-15% currently, so monitor intakes, and supplement where necessary.
Continue to supplement suckled cows at grass with magnesium post weaning. There have been many reports of tetany, as nights have been getting colder.
The calcium in lick buckets will also help to prevent milk fever in milkier type cows.
Growing weanlings and store cattle
Young stock destined for further feeding or breeding on grass alone are not thriving well and now need supplementation to maintain performance.
Advanced stock out on grass are not thriving well at present and should be supplemented on grass or housed for finishing at this stage of the year. Watch that cattle on heavy feeding do not get acidosis post housing. Introduce concentrates and/or beet slowly, to prevent digestive upsets, and watch for indications of poor rumen function, such as loose dungs, cud balls, drooling of saliva, and lameness.
