How can I find my cow is pregnant

Pregnancy is best checked by a vet exam or ultrasound. In general, a cow may show no heat after breeding, her milk yield may dip a little, and the belly slowly starts changing after a few weeks. For a more exact check, blood or urine progesterone test can be done at twenty eight to thirty five days after AI, and confirmation is usually by ultrasound or rectal exam at sixty to ninety days. If you want to buy a cow, always milk her in your presence and check all four quarters with a CMT test.
