Cows are at their most fertile between 60 and 80 days after calving. Cows remaining "open" (not with calf) after this period become increasingly difficult to breed, which may be due to poor health. Failure to expel the afterbirth from a previous pregnancy, luteal cysts, or metritis, an infection of the uterus, are common causes of infertility
Most beef cattle are mated naturally, whereby a bull is released into a herd of cows approximately 55 days after the calving period, depending on the cows' body condition score (BCS). If it was a cow's first time calving, she will take longer to re-breed by at least 10 days. [ 4 ]
A few mammalian species, such as rabbits, do not have an estrous cycle, instead being induced to ovulate by the act of mating and are able to conceive at almost any arbitrary moment. Generally speaking, the timing of estrus is coordinated with seasonal availability of food and other circumstances such as migration, predation etc., the goal ...
“We didn’t think dairy cattle were a host for flu, at least a meaningful host,” Andrew Bowman, a professor of veterinary preventive medicine at Ohio State University, told NBC News this summer.

Today, clip art is used extensively and comes in many forms, both electronic and printed. However, most clip art today is created, distributed, and used in a digital form.
However, not all mutilated animals display these anomalies, and those that do have slightly different anomalies from one another. On account of the time between death and necropsy, and a lack of background information on specific cattle, investigators have often found it impossible to determine if these variations are connected to the animals ...
