Another postdoctoral scholar working with the team, Essam Abdelfattah, is exploring the costs and benefits of alternatives to control the problem.
“Everybody brings a new perspective and a new piece of information, and overall, it's a synergetic collaboration because everybody bringing their expertise is a much better result,” said Ferreira.
The team thought certain feeds might be contributing to the bunching problem because their odor and water content can increase fly breeding. They are studying removing fly attractants from the rations, adding fly deterrents and other strategies to mitigate flies, such as erecting short cement walls to impede leg-biting flies.
Rossow and Ferreira also study the production and economic impacts of adding supplements to feed. “The areas that we work in complement each other so well, because for dairies the largest cost is nutrition,” said Rossow. “Any way that dairies can become more feed-efficient and produce more milk for less is a major benefit to the industry.”
Jersey cows aggregated in a circle with signs of tail switching and foot stomping as protective behaviors against stable fly attack. Such aggregating behavior is commonly known as cow bunching.

Their collaboration has focused on understanding what supplements are beneficial to production and economically feasible to introduce. Rossow values the unique practicality that Ferreira brings to their model. “To have someone who can do an examination and look at historical milk prices and historical feed prices and come up with some guidelines is just incredible,” she said.
“These kinds of collaborations help us to ultimately benefit our clientele by translating research into a more digestible language and applied knowledge to improve their production,” noted Ferreira.
Rossow and Ferreira discussed the importance of networking across the system to advance one’s career. They advise talking to as many people as possible to look for complementary areas of research. “You'll come up with new ideas and new collaborations, and on top of that you'll know what resources are available,” said Rossow. “They can give you ideas on where to go to get funding and actually get projects done,” she added.
“We need to answer questions that are coming from the farmers and producers,” Ferreira commented. “Working with multiple people from different backgrounds and different specialties but with a common objective ultimately has also made me learn more about myself, which is really important.”
Rossow appreciates that Ferreira is skilled at making connections. “The ability to do that is a huge asset, and she's a good model for incoming faculty and extension personnel on how to get up and running on a program as soon as possible.”
