Winter Forage 2014
We are fast approaching the winter feeding season and many 1st cut silage clamps made in spring 2014 are now being opened. There is a wide range of silages made this season due to the variable weather conditions in May. National milk production is beginning to fall over the past few weeks. Milk quality is also very variable with both low protein and low butterfat levels being reported.
Season Averages So Far
The table below shows the average of the samples received by the lab so far this season:

Dry matter is good as an average but there is a wide range from 17% to over 50%. ME and D Value are significantly lower on average than last season.
Grass silages can probably be split into four main categories
• Low dry matter, highly acidic 20% DM, 10.8ME, 48% NDF
• High Dry matter, low ME high fibre 35+% DM, 10.0ME, 55%NDF
• Good all round 28% DM, 11.4ME, 45% NDF
• Traditional 28% DM, 10.5ME, 50% NDF
These silages will require very different nutritional approach this winter.
The table below shows the amount of silage and compound required for M + 30 litres and recommended type of compound for each type of silage.

Balancing Diets
The exact balance will depend on the individual silage analysis and on farm circumstances.
There may be a requirement for additional products to balance particular silages. For example, it is likely that the high acid silages will require a rumen buffer (Acid Buf) especially with high levels of compound. Also some of the high dry matter low D value silages may benefit from adding some Amaferm.
Current Milk Production
Based on Dairy Co Figures, daily milk production has continued to fall. This was particularly affected by the extreme heat at the end of July. Production has fallen by around 3.5% since the middle of July. This equates to around an average of 1 litre per cow per day.

Production is still significantly above the previous two years’ production. However, the next 8 weeks production will be critical in terms of winter production. With grass growth levels falling in the past few weeks, feeding management will need to be altered to maintain levels of milk production and cow body condition.
Overall the current level of production is unlikely to result in the UK being over milk quota in the final year of quotas.
