Putting animal waste back into the food chain as animal feed is apparently
state of the art now. Wonder if this could have something to do with the
emergence of diseases like avian flu and mad cow...

was notified it was too long--unfortunately today you have to register at

Pro-Cal Turns Waste to Feed
By Laura Bruegge

Previously, the waste fat skimmings — a byproduct of poultry processing —
were “hard to handle.” They had to be mixed with other materials, such as
soybean meal, if they were going to be used as feed for domestic animals
such as chickens and cows.
In January, Simmons opened a $10 million, 125,000-SF commercial production
plant in Southwest City, Mo., dedicated to making Pro-Cal.
Currently, the wastewater is pumped from poultry kill rooms to a treatment
plant where the DAF skimmings are recovered. The blood, fat and protein
material is then pumped or trucked to the Pro-Cal plant. It is blended,
mixed and heated. From there, more water is extracted before the product
goes into the dryer. The end product is a rust-colored powder.
Previously, Simmons added cooked blood from its slaughter operations to
its feather meal. About six loads of DAF skimmings had to be hauled away
every day from Simmons’ processing plants in Southwest City, Jay, Okla.,
and Siloam Springs. Those plants combined process 3 million broilers and
355,000 breeder hens per week, Haid said. The plant has the capacity to
handle ten 50,000-pound loads of DAF per day.
If Simmons costs associated with land applying DAF skimmings were applied
to the average weekly poultry slaughter rate of about 168 million birds
nationwide (based on Watt Poultry USA 2005 data), it would mean a cost
savings of about $588,000 per week or $30.6 million annually.
Simmons is currently producing about 350 to 400 tons of Pro-Cal per week,
Haid said. The plant has the capacity to produce 17,000 tons per year,
which could be doubled with an additional dryer. The majority of the
product is fed internally to about 17 to 18 million of Simmons’ birds
weekly. The balance is shipped to dairy operations of about 5,600 head of
cattle in western Kansas.
Gene Woods, president of Pro-Cal, said Pro-Cal is valuable in a dairy
cow’s diet because of its quality as a bypass fat and protein.
“Basically, they are taking a waste product that has been a nuisance and
making it a valuable feed ingredient,” Waldroup said.
