How RFID delivers big data on cows and milk production
We know that big data has been used in retail, healthcare and finance, but you might be surprised to find out that it also helps farmers with dairy production. This practice, called precision dairy farming, involves the use of technology such as RFID tags and sensors to track the health of cows, which are essential to the economy in areas such as India.
Vishvas Chitale, director of Chitale Dairy in Bhilawadi, India, explained the role the grass-grazing animals play for farmers. “It’s very important for them as revenue because for farming companies in India we call cows ATMs.”
“If you feed the animal, you get milk the next day,” Chitale said. “By a week’s time you get money, and that’s very important for the rural community in India. That’s why we’ve been able to sustain for the last 75 years as an organization.”
The company produces about 500,000 liters of milk a day, along with cheese, cottage cheese, cream, butter, yogurt and skimmed milk powder.
Chitale sells about 60 million liters of milk a year from its dairy farm and smaller farms in Bhilawadi. From 2014-2015, India has exported more than 66,000 metric tons of dairy products, according to the Indian government’s agricultural and processed food products export development authority.
For Chitale Dairy, the goal is to increase the amount of milk production while reducing the number of cows, which in great numbers contribute to the amount of methane in the environment, Chitale said. “By reducing the number of cows, we can really help the environment,” he said. “We want to have less cows but more productivity.”
The dairy deploys a “cows-to-cloud” strategy to increase the milk yield. Farmers access the data in a cloud portal and use the data to help with animal trading. “It’s like creating an ecosystem whereby all the stakeholders get the benefit of the compute,” Chitale said. “If [farmers] want to trade their animal and we publish that information about her health, it provides value to them.”
At a weekly bazaar, the Chitale Dairy farmers receive money in exchange for the cow milk they’ve produced for the week. In addition, many farmers in India are trading cows online.
To monitor the cows, Chitale Dairy places Allflex RFID tags in cows’ ears to receive information on whether the animals are in heat or need to be vaccinated or dewormed. This information is transmitted via the cloud to farmers’ mobile devices.
Farmers call the Chitale Dairy call center, which sends the data to a mobile app, with the RFID number matching up with a particular cow. The farm then sends a to-do list to farmers in their local language each morning on what each cow needs based on the data collected from the RFID signals. (Companies such as Allflex, GEA and Y-Tex offer these RFID tags.)
Chitale Dairy maintains a database of 10,000 animals, along with a complete progeny and medical history.
“The secret of the whole system is this is cow 1626, and whatever data I collect relates to her,” stated Michael Hutjens, professor emeritus in animal sciences at the University of Illinois. “The beauty of the tag is the ability to track the animal.”
Chitale Dairy uses the data to track blood profiles and the nutrition requirements of cows, such as whether the animals are getting the proper iron or calcium. From the data received by RFID tags, Chitale Dairy performs mineral mapping and blood profiling.
Monitoring the data allows Chitale Dairy to increase milk production by more than five liters an animal, Chitale said.
The sensors also keep track of how much a cow eats per day. “If one day cows only spend one day eating, then these alerts tell us something is going on with this cow and then we can look at her and try to find the best course of action,” said Jeffrey Bewley, associate extension professor at the University of Kentucky.
“The whole idea is to have a complete life cycle of the animal,” Chitale said. For example, the system sends messages on whether a cow is having a calf. The dairy farm also uses genetic mating software to track whether offspring are producing with “greater genetic gain” than their mothers.
By monitoring the health of cows using RFID tags and sensors, farmers can detect whether the animals suffer from conditions such as mastitis, a potentially fatal infection of the udder tissue, or lameness, which is difficulty in moving around.
Discovering mastitis is a top parameter for farmers to adopt precision dairy technology such as RFID, according to Bewley and fellow University of Kentucky researcher Matt Borcher. Other factors include standing heat and daily milk yield.
