A Danish cow, four years old, third calf, and her son, a five-month-old calf. I bought her in Ramadan from Al-Taktak. The account was Abu Abdulaziz Al-Dossari and the person's name is Abdullah Al-Hujailan from Buraidah. He said she produces 16 liters, and with me, she produces 6 to 7 liters. Besides that, she was leaving the calf. I changed her feed, and she got diarrhea, may God honor you. After that, she didn't eat well, and her milk production decreased significantly. I brought a veterinarian, and he said she has a heart problem due to eating metal that penetrated the rumen, and this problem occurred a long time ago. I haven't given her any medications. Here are pictures of her and her son, and there is a video. God knows best about the doctor's words. Whoever wants to buy her alone, or with her son, or the calf alone, there is no problem.
