Feeding the World: A Global Perspective on Dairy Farming

Mission of state to feed their population

The mission of states is to ensure all citizens have access to healthy and nutritious food, encompassing both its production and distribution.

Dairy production, a crucial role in providing essential nutrients

Milk and dairy products are rich sources of protein, calcium, and vitamins which are vital for growth and development, especially for children and the elderly.

States must support the dairy industry through policies that promote sustainable practices, improve animal welfare, and ensure the quality and safety of dairy products. Investing in research and development can lead to innovations that enhance the efficiency and sustainability of dairy production.

EarlyFerty, your individual immunologic rapid test, faster and easier in detecting pregnancy

Our individual immunologic rapid test is a simple diagnostic tool that detects specific proteins with only a few drops of blood, using antibodies that react to these markers. EarlyFerty works by detecting a natural protein found in the blood of pregnant cows, giving a clear result in 20 minutes.

PAGs, The Early Sign

You Can Trust

PAGs or Pregnancy-Associated Glycoproteins are proteins belonging to the subclass of aspartic proteinases produced by trophoblast cells.

During pregnancy, cows produce these special proteins (PAGs) that appear just days after embryo attachement and stay throughout gestation. Since PAGs are only found in pregnant animals, EarlyFerty’s rapid test is highly specific and can detect pregnancy as early as 28 days after AI, helping you act quickly and manage your herd.

One Test. Multiple Species.

EarlyFerty isn’t just for cows.

Thanks to the detection of Pregnancy-Associated Glycoproteins (PAGs), the test is equally reliable for other ruminants and Artiodactyla species. Whether in goats, sheep, buffalo, deer or camels, EarlyFerty delivers the same fast, accurate results, helping farmers and veterinarians make timely decisions across different herds.
