The second breeding phase of the rut takes place three to four weeks after the first breeding phase. This is due to younger cows coming into estrus, as well as older cows that were not bred on their first estrus cycle coming back into estrus. Herd bulls are less aggressive towards satellite bulls at this phase in the rut due to exhaustion. [14]
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
Research shows that milk production may be negatively impacted if cows do not acquire enough protein during their dry phase. [13] If farms are unable to provide separate diets for far-off and close-up cows, producers may choose to manage their diets with a shorter dry period and a negative DCAD (dietary cation-anion difference) ration diet.
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 ...
An article from Maurice Eastridge, a professor in the department of animal sciences at Ohio State University, noted that having between 3% to 5% sugar in a dairy cow's diet can help with proper ...
Without ovulation, she may enter interestrus, which is the combined stages of diestrus and anestrus, before reentering estrus. With the induction of ovulation, the female becomes pregnant or undergoes a non-pregnant luteal phase, also known as pseudopregnancy. Cats are polyestrous but experience a seasonal anestrus in autumn and late winter. [19]
The Ohio Department of Agriculture confirmed an Ohio cattle herd in Wood County has tested positive for bird flu.The test result is awaiting confirmation from the U.S. Department of Agriculture.
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]
