Are there environmental factors that can cause hydrocephalus in cattle or is it always a genetic condition?

While genetics can play a role in the development of hydrocephalus in cattle, environmental factors can also be contributing factors. Some environmental factors that have been linked to an increased risk of hydrocephalus in cattle include:

1. Nutritional Deficiencies: A lack of certain essential nutrients, such as vitamin A, copper, and iodine, during the early stages of development can increase the risk of hydrocephalus.

2. Viral Infections: Infections with certain viruses, such as bovine viral diarrhea (BVD) and bovine herpesvirus-1 (BHV-1), during pregnancy can lead to the development of hydrocephalus in calves.

3. Trauma: Physical trauma to the head of a calf during birth or soon after can also cause hydrocephalus.

4. Toxic Substances: Exposure to certain toxic substances, such as lead, mercury, and some pesticides, can also erhöhen the risk of hydrocephalus.

It is important to note that the exact causes of hydrocephalus in cattle can be complex and may involve a combination of genetic and environmental factors. Therefore, if you suspect that a calf may have hydrocephalus, it is essential to consult with a veterinarian for proper diagnosis and management.
