the bull detects the oestrus about 2 days before 

he picks his moment by taking a sample

New herd members can be a useful means of stimulating

sluggish bulls

Mounting causes an immobilisation reflex in the oestrous females that are being mounted

the circulating endocrine balance

some receptive cows sniff males or involve in mock fighting

indiscriminate agonistic interactions
pawing the ground and snorting he rests his chin on her rump 

Cattle have slit-shaped pupils and weak eye muscles

Cows that are in heat will exhibit telltale signs such as riding and being ridden by other cattle

23.12.21.12.12, 

they stroll around sniffing for pheromone fluids sometimes lapping exuberantly

the pasture  


The flehmen response assists pheromones and scent molecules in reaching the vomeronasal organ in the roof of the mouth
