Estrus in a cow or heifer only lasts for ~24 hours.
21 days
The length of estrous for cattle is approximately 21 days. The estrus period last about 18 hours.
A cat's heat period (also known as estrus) can last anywhere from 3 to 14 days, with the average duration being around 7 days. Cats typically go into heat seasonally, with peak periods occurring in the spring and fall.
A female dog's heat cycle or estrus typically lasts around 2-4 weeks. This cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus. During the estrus stage, which is when she is fertile, the female dog may actively seek out males for breeding.
The entire heat cycle lasts about 20 days. 14 days in diestrus (not in heat) and 6 days in estrus (heat). There are a number of variables that can change this ratio, exposure to a stallion, early embryonic death, infection, hormone imbalance, ovarian and pituitary tumors.
Same amount for a beef cow: estrus is around 24 hours. Estrous is 21 days long.

Cows do not have "periods." They have what are called Estrous periods or cycles. They last around 21 days long, with heat or estrus lasting around 24 hours.

Wait for 12 hours after you've last seen her estrus activity before AI'ing a heifer or cow.
All dogs have typically two estrus or heat cycles a year about 6 months apart that last 2-3 weeks For a Great Dane, 9 to 12 months is not unusual.
Cats, known for their enigmatic behaviors and independent nature, exhibit a fascinating range of reproductive behaviors. One of the most notable and often challenging aspects for cat owners is managing a cat’s heat cycle. If you’re a first-time cat owner or if your cat is going through her first heat, understanding the duration and characteristics of this phase can be crucial. This article will explore how long a cat stays in heat for the first time, the signs to look for, and how to manage this period effectively Understanding the Feline Estrus Cycle Before delving into the specifics of the heat cycle’s duration, it’s essential to understand the feline estrus cycle. The estrus cycle, or heat cycle, is a natural part of a female cat’s reproductive system. Cats are seasonally polyestrous, meaning they can go into heat multiple times during a breeding season, typically influenced by the length of daylight. The estrus cycle in cats consists of several stages: Proestrus: This is the preparatory phase lasting 1-2 days, where the cat begins to show signs of coming into heat, such as increased affection and restlessness, but she is not yet receptive to mating. Estrus: This is the actual heat phase, lasting anywhere from 4 to 10 days. During this time, the cat is receptive to mating, and you’ll notice more pronounced signs of heat. Interestrus: If the cat does not mate during estrus, she will enter this phase, which lasts about 1-2 weeks. If she does not become pregnant, she will cycle back into estrus. Diestrus: If mating and ovulation occur but the cat does not become pregnant, she will go into diestrus, a period of inactivity in the reproductive cycle. Anestrus: This is the resting phase between breeding seasons, typically occurring in the winter when daylight hours are shortest. Duration of the First Heat Cycle When a female cat (queen) goes into heat for the first time, it usually occurs around the age of six months, although it can vary between 4 and 12 months depending on the individual and breed. The first heat cycle can be a bit unpredictable in duration but generally follows the typical estrus pattern. For most cats, the first heat cycle can last between 4 to 10 days, aligning with the duration of the estrus phase. However, since this is the cat’s first experience with estrus, the signs might be less pronounced or slightly irregular compared to subsequent cycles. website : emmoceb
Like Females we have are period and female dogs also have there period every six months.But there is called heat not a period it usally last up to 3 weeks.
9 weeks to 2 months
The entire heat cycle lasts about 20 days. 14 days in diestrus (not in heat) and 6 days in estrus (heat). There are a number of variables that can change this ratio, exposure to a stallion, early embryonic death, infection, hormone imbalance, ovarian and pituitary tumors.
