OK, I got it, BioE programs are not quite like old Agricultural Engineering…
In January of this year, Beijing’s mayor announced that his city was no longer “livable” on account of the air pollution levels that take a daily toll on its 21.5 million inhabitants. Today (November 30, 2015), never mind odours or visibility, airborne particulates reached 976 µgm-3, whereas the safe level is… 25 µgm-3.
My better half and I just returned from a business trip in China’s Inner Mongolia, where I presented some tips for the design of no-till corn planters, at No-Till & Conservation Tillage Workshop hosted by a local manufacturer, and chaired by Professor Li Hongwen, director of the National Soil Conservation Centre, housed in the College of Engineering of the China Agricultural University in Beijing. We also spent a couple days in Beijing, and we didn’t see the sun shine for very long…

What was formally the AgTEch Centre in Lethbridge Alberta has been given a new name and renewed focus.
The Farm Stewardship Centre in Lethbridge provides a renewed focus on applied research, evaluation and implementation of new methods and technology aimed at reducing the environmental footprint of farming and food production.
“Established in the 1980s, the Lethbridge research facility continues to evolve to meet the needs of the agriculture sector. Under its new mandate, the centre is undertaking projects that range from the assessment of greenhouse gas emissions linked to fertilizer to developing systems that improve water and energy use on farms.” Says Virginia Nelson, Director of Engineering and Climate Services.
Strengthening environmental stewardship practices is crucial to the responsible growth of a strong and sustainable agriculture sector that will help further diversify the Alberta economy. The staff at the centre work closely with producers, commodity groups and the research community to explore innovative approaches to grow food and care for the environment.
The long-term success of the agriculture industry relies on Alberta continuing to show leadership in sustainable and environmentally responsible development. The Farm Stewardship Centre is a resource for agriculture producers to help them make informed decisions about how to best manage their operations.
The work at the centre will complement other government initiatives including Growing Forward 2, which are designed to support the development of a sustainable and competitive agriculture industry.
Through the federal-provincial Growing Forward 2 program, producers and agri-businesses have access to funding to support advances in animal health, food safety, market access, value-added industry development and environmental stewardship.
On September 24, the annual UMCSBE & Biosystems BBQ was held at the University of Manitoba. The BBQ is a great opportunity for networking for students and professionals alike.
This year, the event was well attended, with about 50 students, 10 industry representatives, and several professors, and a good time was had by all.
Mark Armstrong, P.Eng. (20 year member) received his Agricultural Engineering degree at the University of Guelph. He founded Armco Solutions Inc. that specializes mainly in two areas; energy savings ideas for new and more efficient technologies in agricultural, commercial and industrial applications; and solutions for indoor air quality in the same sectors. Mark’s advice for younger members is to ‘Find a niche that the industry needs, but not everyone else is doing. Work on expressing your ideas and remember that presentation is very important.’
Michael Toombs, MSc., P.Eng. (27 year member) received his Engineering degree at Concordia University and his Masters at the University of Guelph. He works for the Ontario Ministry of Agriculture, Food and Rural Affairs at Guelph. He has held several positions with OMAFRA, but now is Director of Research and Innovation focusing on research priorities for the agricultural, food and rural affairs sectors and on research infrastructure renewal. Two examples; the new $25 m Elora dairy research facility, a joint project between the Agricultural Research Institute of Ontario, University of Guelph, and the Ontario dairy; and the new $10 m research greenhouse at the Vineland Research and Innovation Centre. Mike’s advice for younger members; ‘Be resourceful, proactive and bring more than the technical to the table’.
Doug Trivers, P.Eng. (29 year member) received his Engineering degree at the University of Guelph. He is the owner/operator of Dayson Agricultural Ventilation Ltd. (daysonav.com). Doug was raised on a small Ontario mixed farm and developed an aptitude for “things mechanical” and agricultural. He decided on Engineering since he was good at math and science. After graduation he worked as an OMAFRA Livestock Energy Specialist; great training to learn the importance of customer service and gain skills in control strategies and energy management. He took a leave after 10 years to test the private sector, and as the ”Remington” story goes “I liked it so much, I bought the Company (20 years ago)”. He provides turn-key ventilation systems to growers for on-farm storage of mainly potatoes, carrots, onions, rutabagas and squash. He specializes in ‘free-cooling’, taking advantage of the cool air available in Canadian evenings and winters. His advice for new members is simple…’READ; a wealth of knowledge is available in trade publications and on association websites to assist learners or entrepreneurs’.
Up until recently, dairy farmers have been hindered in quickly detecting possible reasons for a reduction in milk production among their herd. One such reason is sub-clinical ketosis (SCK) when an affected cow appears to be well but only becomes observably under stress when SCK becomes full ketosis affecting major organs, or it could be other metabolic diseases. The only true method of detecting these abnormalities was by taking vials of the affected cow’s blood and sending samples to a lab for diagnosis. However, Bionanolab of the School of Engineering has advanced this procedure by putting the ability to diagnose a cow’s health in the hands of farmers themselves, thereby saving crucial time in detecting certain bovine metabolic irregularities, and thereby providing earlier treatment.
By detecting certain enzymes in blood, the newly developed device can pick out these biomarkers present in miniscule amounts and help identify diseases. A combination of the device’s unique composition of electrodes, a plant enzyme, and the correct amount of electric current were discovered by the Bionano research team to be the winning formula used collectively in the device known as a “Gryphsens”.
A New Tool on the Farm
Through the implementation of a hand held sensor, a dairy farmer can rapidly detect whether a cow has sub-clinical ketosis or other metabolic diseases through a small amount of blood being taken and having the sample analyzed in real-time through interfacing with the Internet by a smart phone. Such technology not only allows a dairy farmer to rapidly determine a cause for a reduction in milk production, but it also allows early detection of metabolic diseases that can then be treated, facilitating a cow to return to its normal milk volume levels in a shorter period of time. The cost saving of such early detection is substantial for small and larger dairy herds.
In the case of larger dairy herds, this Canadian invention that uses a unique electrochemical measurement of samples can be engineered for use with in-line robotic milking machines to monitor a herd individually, yet collectively, to avoid the repetitive and time-consuming method of testing each cow separately. The sensor, developed at Guelph’s Bionano laboratory of the School of Engineering by a team headed by Dr. Suresh Neethirajan is able to detect minute electrochemical activity in biological fluids that indicate biomarkers for certain irregularities and diseases. These markers flag slightly elevated levels of non-esterified fatty acids (NEFA), and a ketone prevalent in cows, β-hydroxybutyrate (BHBA), that at higher levels can both signal the early onset of ketosis and other metabolic diseases.
A Critical Time Line
Historically, the calving period is a stressful time for cows, described as a time of negative energy balance (NEB), when the onset of ketosis or other metabolic diseases are most prominent. Although the levels of NEFA and BHBA are miniscule at the beginning, early detection can reduce complications and a faster recuperation period, otherwise a later detection could lead to fatty liver, ketosis, displaced abomasum (twisted stomach), and inflammation of the uterus or a retained placenta. Dairy farmers are highly cognizant that charting a cow’s NEFA and BHBA levels is the litmus test for the animal’s overall health. One of the great advantages of testing for on-farm dairy cow diseases using our developed biosensor is that it not only significantly reduces the stress on the animals due to relying on a drop of blood instead of vials sent, but also provides instant test results.
The Lab Comes to the Barn
Traditionally, these levels are determined through expensive and lengthy tests performed in laboratories. Through electrochemistry and nanotechnology the University of Guelph’s Bionano team has made it possible for dairy farmers from all scales of operation to ascertain for themselves their herd’s health. Although humans have similar devices for measuring glucose levels for diabetes, the cow’s organism presents a further challenge by having 11 major blood groups versus four. The challenge was developing the sensor’s electrode that could simultaneously detect both NEFA and BHBA in variable metabolic conditions that can include a number of interfering components, which could alter the test results. Ability to detect multiple disease biomarkers from just a droplet of blood sample that could be used by untrained farmers is unique.
A Plant with the Answer
An issue the University of Guelph team had to surmount was the insulating property of GO that hindered the electrochemical function crucial for the biosensor. A particular enzyme from the soybean plant was integral in solving this problem and was incorporated into the dual electrodes. Although lipoxygenase is found in animal and plant species, using soybean lipoxygenase-1 (SLO) was itself a first for catalyzing direct electrochemical oxidation of NEFA in conjunction with graphene oxide nanomaterial. The result is a biosensor that has a dual function of detecting NEFA and BHBA in less than a minute on-site by the dairy farmer using a small sample of whole blood. Dairy cattle are an investment that must be kept in prime condition to maintain optimal production levels, and the Canadian biosensor is the latest tool for dairy farmers and large scale operations to monitor the health of their herds. The dual sensor can be an important part of routine screening used by farmers in the dairy barn.
