Failure to expel the afterbirth from a previous pregnancy, luteal cysts, or metritis, an infection of the uterus, are common causes of infertility
Pregnant, lactating, and elderly women, for example, are susceptible to anemia and low bone density, mainly due to inadequate iron and calcium intake — nutrients readily available in red meat ...

Later, the food is regurgitated to the mouth, a mouthful at a time, where the cud is chewed by the molars, grinding down the coarse vegetation to small ...
By using cows that produce offspring within a one to two-week period, synchronized breeding allows dairy farmers to artificially inseminate cows for maximum pregnancy rates with minimal effort. [29] BST is a placental lactogen (PL) hormone and falls under the class of growth hormone, or somatotropin.

If it was a cow's first time calving, she will take longer to re-breed by at least 10 days. [4] However, beef cattle can also be bred through artificial ...
