I got the notion somewhere along the way that unlike deer or antelope that run in the face of danger, a cow has to stand and fight when predators come calling. Most predators are hunkered down during a rain or snowstorm, so its an opportunity for the cow to give birth unmolested. The rain and snow also wash away scents and trails. So evolution or Darwin tells me the risk of predator is larger than the risk from weather. So a drop in pressure signals the cow to drop the calf while the weather is bad. Also if you think about it, mankind is forcing these cattle to calve in January Feb. or March. Left to nature, they would loose their calves to early weather and eventually their pregnancy/birth cycles would sync to calving in May/June when the ground is warm and a rain not so bone chilling? Far less chance of hypothermia. Any thoughts???? Also, cattle have been domesticated a looong time, so bison or water buffalo may be a better example of how they would reproduce naturally. And even though we don't have predator issues much today, we're talking about 10s of thousands of years of evolution that makes them act the way they do. And then again...what do I know????
