Understanding the analysis
• The first step is to identify the cows’ allowances for energy, protein, fibre and minerals based on bodyweight and yield.
• The next step is to determine the supply of nutrients from the feeds and supplements the cows are getting
• The difference between these two is the gap which needs to be filled. The mineral/trace element gap should be filled.
Most Dairy Companies have been giving their suppliers their herd bulk milk, Milk Urea (MU) figure for some time now. For the last few weeks MU has been available on fencepost for Fonterra suppliers.
Over the last few weeks many farmers have been asking me questions about their MU levels and how this affects their herd production and reproduction.
Understanding your urea levels can help optimise farm performance, by improving rumen efficiency - conversion of feed to milk and also reduce the impact on environmental nitrogen loading, reduce animal stress and possibly improve herd fertility.
When considering calcium in dairy cows, most people think of milk fever (clinical hypocalcaemia). This is something we can see but it is the unseen consequences of subclinical levels (lower than normal) of calcium in the blood that may have the greatest impact. Most commonly seen in mature cows around calving and early lactation (transition), hypocalcaemia can occur in any cattle at any time.Read Post
Best understood as the milk produced from the purchase of feed over and above what is produced within the farming system
It is only viable as long as the extra cost of producing the milk is less than the price being paid for the milk.
