lowing the passing of
large solids in suspen- sion.
The downside of these pumps has been the limited heads de- livered often top out at around 20m.
“These units were designed for opera- tors in piggeries, sale- yards, dairy farms and chicken feeding estab- lishments,” Mr Hales said.
Aussie Pumps has designed a new high- pressure semi-trash pump with truly amazing performance.
With a maximum flow of 1200 litres per minute, the pump’s performance is excep- tional.
“We know customers want to not only pump the liquid but often to pump it a fair distance fromtheyard–toa holding pond or some form of irrigation.”
An addition to the Aussie Pumps GMP semi-trash pump range, the pump combines the ability to handle solids in suspension with a maximum head of 80m.
A major advantage is the ability to self-prime through a vertical lift of 6m, allowing it to pump from the pit and then distribute liquid effluent at pressure.
Aussie Pumps in- tends to bring a wide range of high-pressure semi-trash pumps to the market.
The pump is self- priming and in mono- bloc execution, with a

No evidence of SVA or PRRS infection was ob- served in pigs consuming feed supplemented with pHorce at 3kg per metric tonne, however evidence of infection – SVA, PEDV and PRRS – and clinical signs were apparent in the positive control popula- tion.
pHorce is a concen-
trated blend of pure
liquid formic and propi-
onic acids on a unique
mineral carrier delivery llensygsetemo–declh.osen to en- sure maximum efficacy during feed manufacture and throughout the gas-
trointestinal tract. Recent trial work sup-
feed bin room.
Viral challenge was
for clinical illness (if ap- parent) 15 days post-in- oculation and pigs were observed daily for clinical signs of infection.
No clinical signs asso- ciated with any disease were seen in pHorce sup- plemented pigs.
ported by Anpario has shown positive results of including pHorce in feed that was co-infected with porcine reproductive and respiratory syndrome virus, porcine epidemic diarrhea virus and Seneca virus A.
administered on days zero and six using the ‘ice block model’, where known volumes of SVA, PRRSV and PEDV were provided in a suitable frozen media, which would melt and permeate the feed before it was au- gured into the designated room.
All samples were evalu- ated for viral presence by polymerase chain reac- tion and nucleic acid se- quencing.
Pigs supplemented with pHorce exhibited lower mortality and a significant increase in average daily gain compared to the posi- tive control treatment.
Feed was identified as a potential risk for con- tamination of porcine epi- demic diarrhea virus and subsequently, the risk to feed associated with other viruses had been identi- fied.
Feeder samples were collected on days zero, six and 15 post-inoculation of the feed.
In addition, performance parameters of start and end body weight and mor- tality were collected from all pigs and analysed for significant difference by analysis of variance testing.
pHorce has been shown to be effective in miti- gating the effects of viral infection from feed.
Therefore, work of this nature is valuable in un- derstanding how these risks can be mitigated. Trial design
Post-mortem samples were collected from 30 pigs per room selected
The full trial method is available upon request.
Recommended min- imum pHorce inclusion for antiviral activity is 3kg per metric tonne.
An independent trial was conducted with Dr Scott Dee at Pipestone Applied Research facility in the US to test the anti- viral efficacy of pHorce using their standard pro- tocol.

Treatments included a positive control (infected feed, no mitigants) and pHorce (infected feed, 3kg per metric tonne pHorce).
Pigs were selected for body weight of 15kg and originated from a naïve herd documented to be free of all three viral path- ogens by monthly testing and clinical history.
