This is false. Bulls are more able to identify a cow in heat by pheromones excreted in her urine, and by her actions of trying to mount other cows, but mostly be other cows mounting her. Bulls "taste" her urine and do a flehman response by curling back is upper lip to smell if she is in heat or not or close to standing heat. A cow in heat can carry pheromones to a bull on the breeze as well, which goes to show you what farmers say when a "bull can smell a cow in heat for miles" is more true than the changes in frequency and pitch in her bellering.
Pheromones. The cow in heat gives off pheromones in her urine and feces, as well as through her skin, to alert a bull that she's in estrus and needs him to settle her ASAP.
Yes.
If she's in heat, most definitely. Often a bull will go look for the cow that is in heat, no matter if he's the neighbor's bull or not.
Yes. A barren cow (one that is open, or not pregnant) is able to come into heat or estrus.
Only if she's in heat and is desperate for a bull to settle her. Otherwise, if she's not in heat or pregnant, she will not be actively looking for or trying to attract a bull to breed with her.
most female pit bull go in to heat when they are 1year and a half at least my red nose pit bull did.
heat in sheep
yes they did
A marker bull is a bull that is used to detect cows in heat but not breed them. The cows that he detects to be in heat are put in a chute to be artificially inseminated. Marker bulls are also called Gomer bulls. Such bulls are bulls that are not desirable for breeding due to structural soundness issues or inferior genetics, and are altered in such away that they are still able to be sensitive to the female's estrus/estrous levels and retain testosterone levels but is unable to conceive successfully. A marker or gomer bull wears a halter with a chin ball attached which enables him to "mark" the cow or heifer that is in heat when he mounts her.
