There are many methods employed to detect if a cow is pregnant. Trans rectal palpation of the uterine horns to determine if one is larger than the other and presence of fluid in the larger one is a method that in less invasive and used often. There is also the palpation of the amniotic vesicle by “placing all four fingers dorsally and the thumb ventrally along the greater curvature of the horn”. After 60 days, the amniotic vesicle becomes flaccid which makes direct palpation of the fetus possible. Adapted nutrition is important in any gestating female. As for cows, their nutritional needs are similar to their maintenance needs in early gestation. As they approach calving, cows need more protein and even more energy when they are lactating.

    When you are going into the fridge to find something to eat or drink, do you think about where the food or drink comes from?

That is why it is so important to have research on dairy cows due to how important they are for human health. Without dairy cows I believe that humans would not have thrived as long as we have due to how many products dairy cows are associated with today.

Ideas that are evaluated are that human gestation is shorter than needed, human fetuses receive less maternal investment than expected during gestation, and that walking upright efficiently requires narrow pelvises and therefore narrow birth canals. Evidence against each of these ideas is presented and statistical analysis of comparative data across other primate species is used to disprove the…
