Gorman-Rupp quality wastewater pump
SOUTHERN Meats Pty Ltd is a hi-tech sheep and lamb processing facil- ity strategically located slightly south of Sydney, where the company has access to sheep grown in the healthy environment of the NSW Southern Highlands region.
unreliable equipment in its wastewater treatment systems.
Additional safety fea- tures built into the pump are designed to protect operators and the pump from damage.
Southern Meats pro- vides quality meat to the local market and exports around the world, using hi-tech automated equip- ment in its slaughtering, boning, chilling, freezing and rendering facilities. The problem
So, when Southern Meats went looking for a dependable and reliable wastewater pump to de- liver 50LPS plus to its treatment area, the com- pany looked no further than Gorman-Rupp.
By using self-priming pumps, asset owners don’t need to buy rated lifting chains or have the yearly burden of inspection or replacement, as would be needed if submersible pumps were used.

In line with its quality approach to processing, the plant did not want its operators spending need- less time attending to
Being able to mount the pump at ground level – and not in the wet well – meant the pumps were safer and more conveni- ently accessible by opera- tors.
Keeping in mind that some of these items re- quire annual trips to the manufacturer for inspec- tion and service.

200 seconds – are indica- tive of sprouted grain that produces a less viscous suspension due to alpha- amylase activity, which hydrolyses the starch to sugars.
While the grain is just sprung – prior to the shoot emerging – all the starch and sugars are retained in the grain and the nutrient value will not have altered.
The solution
Gorman-Rupp is the world leader in self-prim- ing pump technology, particularly in wastewater pumping applications.
And because wet well lids remain closed, the ne- cessity of having fall pro- tection equipment – such as anchorage points, body support, connectors and descent rescue equipment – is greatly reduced.
The results
Southern Meats plant engineer Mick Speering is very pleased with his purchase and more than happy to recommend Gorman-Rupp pumps to anyone wanting a quality wastewater pump.

Falling number has no impact to nutrient value of feed grain
Therefore, AusScan On- line conducted a study in which 23 samples of sprouted grain from the 2021-22 harvest were ana- lysed for falling number, test weight and digestible energy values.
In the falling number test, the wheat sample is ground, mixed with water and heated to form a ge- latinous suspension, and the falling number value is the time taken for a metal stirrer to fall through the gelatinous suspension.
In 2008, Black found that germination periods from 16 - 48 hours significantly reduced the falling number.
The falling number value is used by industry to determine the degree of sprouting in suspected
Low values – less than
The results showed ac- ceptable energy values for pig faecal digestible – see Graph 1 – and broiler ap- parent metabolisable ener- gy – see Graph 2 – ranging from 13.5 - 14.0MJ/kg and 12.5 - 13.0MJ/kg across the range of falling number values.
However, the broiler AME content improved for barley and was unchanged for sorghum and triticale, though wheat broiler AME content was initially re- duced after 20-hour germi- nation but recovered after 48-hour germination.
termine whether the degree of sprouting as indicated by the falling number is rel- evant to the nutrient value of the feed grain.
Alpha-amylase enzyme activity is activated when mature grain is rained on prior to harvest, hydrolys- ing the starch to sugars.
Once the shoot emerges, energy reserves begin to be drained and the test weight will begin to fall.

ing abattoirs or boning rooms that the compli- ance requirement was terribly onerous,” Bruce said.
tling bullying bureau- cracies has become a sad way of life for small livestock producers and the consuming public is typically the loser.
PrimeSafe became the sole authority regulat- ing the production of meat and seafood in the state.
“And that the regula- tor was draconian and heavy-handed and ap- plied these regulations that were not appro- priate to small-scale farms.”
And that’s not right, because it’s the public who pay the taxes to fund the bureaucrats.
In the eye of the regulator, small-scale producers became the biggest potential risk area because they often didn’t understand the rules or couldn’t afford to employ food-safety officers.
So, Bruce closed his business and Sommer- lad chickens became inaccessible in Victoria.
A close look at the names that make up the boards of such influen- tial bodies usually re- veals a liberal dose of powerful ‘big boys’ and maybe a few ‘big girls’, but typically no ‘little boys’ or ‘little girls’.

Unfortunately, the feed grain quality data reported in the AusScan Early Har- vest Reports were not able to compare sprouted and normal wheats.
This study was conducted at the NSW Department of Primary Industries AgEn- viro Testing Services in Wagga Wagga, and the samples were supplied by the University of Sydney Plant Breeding Institute at Narrabri.
Wheat that has not been weather damaged has un- hydrolysed – or high in- tegrity – starch, which will form a more gelatinous suspension and record a falling number of 300-400 seconds.
The test weights for these grain samples were not low and therefore the degree of sprouting was not ad- vanced.
Much safer and much easier to maintain.

The falling number val- ues showed that more than half the samples recorded 62 seconds, with 21 out of 23 samples being less than 200 seconds.
Other broiler production indices – such as growth rate and feed conversion efficiency – were positive- ly impacted by sprouted barley and unchanged for sprouted sorghum and triti- cale.
Only two samples were greater than 300 seconds.
As noted in previous ar- ticles from APRIL in this publication, livestock stud- ies provide good evidence that sprouted wheat in some cases can improve growth rate in young pigs and poultry when included in diets.
The test weights – not presented – ranged be- tween 72.6 - 80.4kg/hL and were considered good for feed-grade wheat.
A total of 21 samples were classified as sprouted grain and would have been downgraded to feed wheat, while all samples have acceptable pig faecal DE and broiler AME energy values.
However, a study from Idaho State University in- dicated feed efficiency was slightly reduced with in- creasing inclusion rate of sprouted grain in weanling pigs but not finisher pigs.
The sprouted wheat sam- ples in this study have an equivalent nutritional value to normal wheat and could be used as a stockfeed in- gredient.
In summary, this study dataset helps to emphasise that sprouted wheat in most instances has an equivalent nutritional value to normal wheat and that falling num- ber is of no consequence when considering grain for livestock feed.
The results indicated that falling number is of no consequence when con- sidering grain for livestock feed.
