Water Delivery

Sunday, October 28th, 2007

Dam water can reduce performance by 20%Water delivery was the biggest cost associated with setting up this cell grazing system.
There is published data stating that cattle drinking clean water out of troughs compared to cattle drinking water out of dams performed up to 20% better in weight gains.

The problem being was the build up of undesirable animal urine and dung around theThe trough set up, 2 litres per second edges of the dams and so eventually the dam becomes polluted. Cattle will still drink from the dambut will not consume the necessary amount of water there for reducing animal performance.

Our floodplains have numerous dams spread across them and would have supplied sufficient water for the cell grazing operation but we too realised how rank the water looked towards the middle to end of the dry season. So we opted to do the job properly and install a trough in every paddock within the cell.The trough set up, 2 litres per second

I gave the job to “Southern Cross” to design the best layout in the paddock and to also supply the correct pump system to pressurize the pipe to achieve the 2 litres per second.

Electric Fencing

Tuesday, October 16th, 2007

See the differance in pasture height.Electric fencing is no doubt the most cost effective means of keeping cattle where you want them. At first, there was no way I was going to use electric fencing. The Northern Territory is a “tough” place with “tough” cattle that need “tough” fencing. Talk about a “Paradigm shift”, I have now tried electric fencing and have been blown away with its effectiveness.

The paddocks in our cell system on our floodplains have been constructed with steel
Star pickets, 25 metres apart with one hotwire running at about 750mm above the ground. Between each picket we attached pink surveyors tape to assist in the wire to stand out. Central station, Larger paddock split into 4 smaller ones.Gateways were made using the Gallagher gate handles and gateways were about 25 metres wide. The majority of the wire was 2.5mm flexi bell by Waratah with 4mm wire running through the centre of the cell to assist in limiting the loss of voltage over long distances.

The Gallagher energizer we use is the MX7500, the most powerful energizer on the market today.Gallager MX7500 Energizer

The earth system that we built involved 3 galvanised star pickets (Waratah maxi extreme) 1.8m long driven into the ground 1m apart. This earth station was located down on the floodplain about 300m from the energizer itself. The pickets were driven all the way into the ground with only a couple of inches left above the ground to attach the earth cable. The small earth area was then fenced off from stock and any possible mishaps with vehicle tyres.

The fencing set-up is actually very fast and cost effective. It’s reliable and certainly creates a psychological barrier.

Why Cell Grazing Works

Tuesday, October 16th, 2007

cell grazing is a process that improves animal nutrition and pasture health. Other outcomes are also very noticeable, such as cattle with a better frame of mind and ease of handling.  Without going into too much detail the process works as follows;

Paddock sizes are reduced using electric fencing. (paddock size depends on cattle numbers and pasture quality)

Large mobs of cattle are rotated through smaller paddocks quickly. Movements within the cell could be as quick as 1 day.

The full rotation through the paddocks within the cell here at Finniss River is 30 days.

So cattle are back were they started 30 days later eating fresh regrowth. It is this fresh regrowth that is the highest in nutrition.

The following help explain the process and principles of cell grazing.
