NO RAIN = NO PASTURE
The very dry conditions in the UK Midlands, is currently very serious for pasture based dairy farmers. Little or no rain has fallen in Shropshire, Staffordshire, Herefordshire, Derbyshire orNottingham for
months. On farm pasture is critical & farmers are heavily feeding. Winter
feed supply is critical. A look at the monthly rainfall patterns in the UK each month
is very revealing.

Not only is rainfall scarce but ground water supplies on
some farms are very low. Some on farm water bores are drawing less than 20% of
normal supply. Daily water demand is more than twice normal due to the dry
diets being fed….concentrates, silage & minimal high DM% pasture. Normal
daily water used for dairy cows is approx 2x daily milk production. Some farms
using electro pulse meters (LMS systems) have recorded daily use as high as
100litres per cow per day. Water tables are very low throughout the Midlands . If the autumn winter rainfall in these areas is
low this will be very serious next summer not only for pastures but for
livestock water supply too.
Phil Evans from LMS http://www.liquidminerals.co.uk/
tells me that the normal pattern of daily water consumption is 40% after am
milking & 60% after pm milking. Water use is seasonal & dependent on
the diet (DM%)
The water demand of a country is usually expressed as the
total water withdrawn from rivers, lakes & aquifers in that country for
different sectors of its economy. However this doesn’t equate to the total
demand for water as a country as many products including food are imported. The
“Water Footprint” of a country or a product like milk is calculated to include
both the direct water used & the virtual water associated with that
product’s production. Unlike carbon footprints of which there are hundreds of
different versions (total shambles!) there is only one agreed water footprint
method of calculation.
On farms there are three types of water available…Green
water = rainfall (not including runoff which is lost). Blue water = surface
& groundwater. Grey water = recycled water including effluent & dirty
water.
Globally animal production takes a very big proportion of
the total water used. 19% of total livestock water is used by dairy
cattle….mainly for feed (drinking water is only a small proportion of the
total). The less cereals in the cow diet usually results in less water use. The
less imported feed also results in less water being used. It looks as though a
total grazing system uses approx 60% of the water of a high input fully housed
system of dairying. A massive plus for pasture based dairying.
Globally the Water Footprint for milk is 1000 litres of water
used to produce 1 litre of Milk.
On farm nothing crashes milk production more than being
short of water. Drinking water is NOT just about water troughs. Rather it’s the
combined impact of the water supply, pumps, water pipe diameter & trough
size. The biggest on farm problems relate to the circulation/delivery water
pipes not being large enough.
The most efficient & lowest cost installation is a ring
main system with minimal laterals to the water troughs.
In the UK we tend to take water for granted. In Australia water is gold! Now we find that we are very short of water in some areas.....its very serious! Its very stressful too.

Situation now critical in Midlands. Can you help with feed?
Contact me if you can help especially if you have organic feed that could be transported into the Midlands. Ring me.
