Sheep Feedlot, Renmark
|Trial Date||April 2016|
To control algae and film sheep drinking habits.
Untreated river water.
Yes, a very high concentration of algae in the cement water trough which required daily cleaning.
Merino lambs/220 (top lot) and Saam lambs/120 (bottom lot).
|Cleaning frequency (pre-trial)||
Every day for feed remnants, dirt and debris.
There were 2 feedlots involved in this trial. These are referred to as the Top Feedlot and Bottom Feedlot for trialling purposes.
- Each feedlot contains an existing cement trough.
- A new galvanised trough was set up with a solar pump within four metres of the existing cement trough in each feedlot.
- Water meters were fitted to all four troughs.
- The cement troughs did not have solar pumps fitted.
- Prior to the trial, the client was cleaning the cement troughs daily to remove algae and feed.
- The client reported no algae in the new galvanised troughs with the solar pump fitted, but a high concentration of algae in the original cement troughs.
- These observations are clearly apparent from the video footage we have collected.
The water meter readings provided conclusive evidence as to which troughs the sheep were drinking from. However, the drinking habits of the sheep appeared to be a little strange; they spent considerable time herding around the cement trough and appeared to be sipping water or licking the cement trough. However, the water meters suggested otherwise.
- In the first week, a water meter was deemed faulty. Three weeks after replacing the faulty water meter, trial readings were resumed.
Galvanised trough with solar pump: 4,593 Litres (4th–25th April)
Cement Trough no solar pump: 486 Litres (4th–25th April)
Galvanised trough with solar pump: 163 Litres (25th–26th April)
Cement Trough no solar pump: 5 Litres (25th–26th April)
*Note - On 26th April the solar pump on the galvanised trough in the Bottom Feedlot was removed and fitted to the cement trough.
