What is one major cause of all reproductive problems in cows?

The most commonly recognized causes for reproductive failure are poor cow nutrition (energy and micronutrients); venereal diseases, such as trichomoniasis (trich) and vibriosis (vibrio); other infectious diseases, such as BVDV, IBR, and leptospirosis; bull infertility, disease and injury; and changes to breeding season …

What causes a cow not to breed?

The most common cause of infertility in beef herds is poor cow nutrition. Over conditioning can also be detrimental, especially in heifers, but is far less common a problem. Body condition before calving, after calving, and at breeding can all contribute to infertility.
