"After ZeroFly Livestock installation, each cow produces 10 litres of milk on average per day, a milk increase of 10%. The animals are at peace and no longer kicking during milking. They are sleeping with ease as they are no longer stressed by the many flies that excited previously. The animals are also feeding comfortably without spilling feeds and milk pours averaging 10% milk loss, which used to be frequent due to biting flies but no more."

"This is a fantastic product that has amazing results with animals sleeping with no disturbance, flies disappearing and animals being stress free and wasting less feed. The milk production has increased from 30 litres to 40 litres, which is a 30% increase in milk production. Milk pours of average 10 litres was being lost weekly due to fly biting and cow being disturbed by flies."

"After installation, the cows have calmed and body condition has improved by 30% due to improved feed intake, feed conversion and the animals are resting better. Previously, the animals were always being disturbed by flies, but today there is no stamping of feet and twisting of the tails. There is no eye irritation due to flies and there is reduction of flies by more than 80%."

"There is an increase in milk production of 10% as the animals are more at peace. No more flies even in the house as the population of the many flies before has disappeared. The animals are able to sleep, rest and are not disturbed anymore. The kicking due to flies used to be frequent due to fly bites causing up to 10 litres milk pour weekly and it's no more after installation of ZeroFly Livestock."

Vestergaard S.A. primarily funds specific projects with specific outcomes. The grantee’s budget for each research agreement should reflect all of the expenses that are required for, and can be tracked directly to, the research project (i.e., direct costs). Vestergaard S.A. allows indirect costs up to 10 percent of the total project costs. For example, for project costs totaling $100,000 - up to $10,000 can be used for indirect costs and the remaining $90,000 can be applied toward project direct expenses. We understand that the indirect cost rates may not cover all of a grantee’s general operating costs, and grantees may need to use other resources to cover these costs.
