Peterborough – Local researchers have developed several strains of algae that can clean waste water as well as serve as a potential livestock superfood.

Nobletech Inc.’s Noble Purification division is currently piloting its algae-based clean water technology, and Noble Biotech has developed sustainable animal feed that is high in protein and omega fatty acids. The company is part of the Greater Peterborough Innovation Cluster.

“Our core technology for both of these applications is the algae product itself,” explains Dr. Andressa Lacerda, a recent Ph.D. graduate of Trent’s environmental and life sciences program. “We’re algae farmers, and we grow algae with different purposes.” Continue reading

New nano sensor detects dairy cattle diseases quickly, easily

Device ready to move to commercialization
By Lilian Schaer for AgInnovation Ontario

Suresh GryphSens Pic1A new handheld instrument can quickly and easily detect two significant diseases in dairy cattle before the animals become sick.

Invented at the University of Guelph by engineering professor Suresh Neethirajan and researchers in the BioNano Laboratory, the nano biosensor uses small test strips to indicate whether a cow has ketosis or metabolic disease by analyzing a small volume of blood or milk.

Nanosensing diagnostic platforms for biomarkers of ketosis and metabolic disease have been developed, which help to rapidly identify elevated levels that can indicate the presence of either of the diseases in animals that appear healthy.

Currently, blood samples must be taken and sent to a lab for analysis, a process that is costly and can take five to seven days to return a diagnosis. Continue reading

Ontario student wins national innovation contest

A Wellington County high school student has won a nation-wide science competition sponsored by 4-H Canada.

Charlene Elliott, a Grade 11 student at Eastwood Collegiate in Kitchener, placed first with her freestall dairy barn scraper concept, which she has dubbed “Lugano 100”.

Scrapers currently used in freestall dairy barns – where cows can move about freely instead of being in individual stalls – will clean manure out of the alleyways, but don’t touch the bedded areas where cows lie down.

Washing and re-bedding resting areas for dairy cows is time consuming work, so Elliott set about devising a system that would automate that process. Continue reading

Livestock bedding offers markets for miscanthus, switchgrass growers

The current wheat straw shortage is sending farmers in search of bedding alternatives for their livestock and poultry.

And they may have found it in biomass crops like miscanthus and switchgrass.

Originally intended for alternative energy production or as ingredients into plant-based plastics and other bioproducts, these crops are increasingly in demand by farmers as livestock bedding for dairy or beef cattle, broiler chickens, sheep or even deep-bedded pigs. Continue reading

Keeping calves free of disease and getting them off to a good start in life is a top priority for dairy farmers Henry and Rose Keunen of Strathroy.

In fact, an integrated milk pasteurizer and calf bottle washer system designed by Henry has won the Keunens a Premier’s Award for Agri-Food Innovation Excellence.
